[0003] April 14, 2025 SKIYI / P Lightweight Fabric with Heavy Appearance Based on Two Warp Yarn Sets with Defined Density and Count-Density Parameters

[0004] The present invention relates to the field of fabrics, in particular textile fabrics such as woven fabrics, and more specifically to the construction of fabrics that visually resemble traditional heavy-weight textiles while maintaining a low overall weight and high mechanical stability. The invention focuses on a dual warp yam system with defined yam density and count-density parameters that ensure improved structural integrity and slippage resistance in a lightweight fabric with a heavy appearance.

[0005] In woven fabric design, the interplay between yam count, yam density, and weave pattern determines key physical and visual properties such as weight, flexibility, durability, and overall aesthetic. Fabrics that aim to appear visually heavy and voluminous typically employ yams with a high yam count (i.e. , coarse yams), resulting in heavy-weight fabrics. These coarse yams provide bulk and a heavy look, and due to their larger cross-sectional area and increased inter-yarn friction, they offer acceptable structural integrity even at lower yam densities compared to fabrics constructed with finer yams, i.e. yams having a lower yam count.

[0006] However, reducing yam density too far in an effort to decrease the overall fabric weight can compromise the internal cohesion of the fabric. A lower number of warp-weft interlacing points and inter-yarn friction results in diminished resistance to yam displacement, commonly referred to as slippage. This becomes especially problematic in garment applications, where fabrics are subjected to mechanical stress during wear and reguire dimensional stability over time.

[0007] Conventional attempts to reduce fabric weight often involve yams with a low yam count (i.e., fine yams) combined with reduced yam densities. While such configurations can yield lightweight and breathable fabrics, the associated reduction in binding points tends to degrade the structural integrity of the textile. Fine yams generally reguire increased yam densities to prevent slippage; however, this approach increases fabricweight and production cost, thereby limiting design flexibility. Moreover, fine yams do not contribute to a visually heavy or voluminous fabric appearance.

[0008] Although coarse yams can help maintain structural stability even at lower densities, this approach has its own physical limitations. When the interlacing frequency falls below a certain critical threshold, the increased volume and friction of coarse yams are no longer sufficient to ensure slippage resistance. As a result, conventional fabric design involves an inherent trade-off between weight, heavy appearance, and mechanical performance.

[0009] It is an object of the present invention to overcome disadvantages of known fabrics, in particular to provide a fabric that combines the visual and volumetric characteristics of a heavy-weight fabric with a significantly reduced overall weight, while ensuring sufficient structural integrity and resistance to yam slippage, particularly under mechanical stress during wear.

[0010] More specifically, the invention aims to overcome the limitations of conventional fabric constructions, which either rely on coarse yams at low densities, resulting in slippage at critical density thresholds, or on fine yams at high densities, leading to increased weight and production complexity without achieving a heavy appearance.

[0011] The invention seeks to enable the design of lightweight fabrics with a heavy look, while maintaining a high number of interlacing points (binding points) and ensuring the dimensional stability of the fabric over time, especially in applications requiring drapability, comfort, and mechanical durability such as garments.

[0012] The object of the invention is achieved by the independent claims. The dependent claims show preferred embodiments.

[0013] A first aspect of the invention relates to a fabric, comprising a first set of warp yams, in particular comprising staple fibers, and a second set of warp yams, in particular comprising synthetic filaments, wherein the warp yams of the second set of warp yams have a lower yam count than the warp yams of the first set of warp yams, wherein the first set of warp yams has a warp yam density of less than 24 warps / cm.As the warp yams of the first set of warp yams have a lower yam count than the warp yams of the second set of warp yams, in the following, the warp yams of the first set of warp yams will be referred to as „coarse yarns" or “first warp yam” while the warp yams of the second set of warp yams will be referred to as „fine yarns" or “second yams”. However, it should be clear that this reference is only intended to make it easier to read the present disclosure. In no case shall the wording „coarse yarn" or „fine yarn" be interpreted as limiting the yams of the first set of warp yams and the yams of the second set of warp yams beyond the limitation that the warp yams of the second set of warp yams have a lower yam count than the warp yams of the first set of warp yams.

[0014] The reduction in warp density for the first set of warp yarns (coarse yams) allows for a lighter and softer fabric without compromising the visual appearance of heaviness, as coarse yams particularly still dominate the fabric’s surface. The presence of a second warp yam system with lower yam count (fine yams) compensates for the lower structural binding that would otherwise result from the coarse yams’ reduced interlacing frequency. Thanks to the lower yam count of the fine yams, the weight of the fabric is only slightly increased leading to a reduction in weight. In summary, the first aspect of the invention provides a lightweight fabric with heavy appearance, while the overall structure particularly maintains a stable, slippage-resistant fabric.

[0015] The term “first set of warp yams” can alternatively be phrased as “primary warp yams”, “coarse warp yams” or “first warp yams”. The expression “second set of warp yams” may alternatively be referred to as “auxiliary yams”, “stabilizing yams, “fine warp yams” or “second warp yams”.

[0016] The term ..staple fibers” may include natural or regenerated fibers such as cotton, linen, viscose, or blends thereof.

[0017] The first set of warp yams preferably comprises cotton or cotton-rich blends (e.g., cotton / polyester), preferably with a yam count in the range of 600-1000 dtex, e.g. corresponding to coarse yams used for denim or similar heavy-appearance fabrics. A preferred warp yam density for the first set of warp yams may lie between 10 and 20 warps / cm, more preferably between 12 and 16 warps / cm. The second set of warp yams may be inserted between each coarse warp yam. preferably in a 1 / 1 plain weave, and may be visually and tactilely masked by the bulkier yams of the first set of warpyarns. The positioning of the second set is preferably alternating or interleaved, ensuring a homogeneous distribution of binding points and uniform structural stability across the fabric width.

[0018] The „warp yam density" or „weft yam density" as used herein may be measured according to DIN EN 1049-2, ASTM D3775, or equivalent standards. The measurement is preferably performed using a fabric sample under relaxed conditions by counting the number of warp yams over a defined length and converting to a value per centimeter.

[0019] The „yarn count", which may alternatively be phrased as ..linear density", can be expressed in tex. dtex, Ne. Nm. or denier. Yam count may be determined in accordance with ISO 2060. The expression “higher yam count” or “lower yam count” as used herein refers to a comparison of count / density values expressed in tex. dtex or denier.

[0020] In the context of this invention, particularly for the purpose of determining warp yam density, yam count, and their product as count-density, the condition of the fabric sample used for measurement may be specified.

[0021] Unless otherwise stated, the fabric parameters relevant to this invention, such as yam count, warp yam density, weft yam density, count-density, fabric weight and binding point density, are to be measured on the woven fabric in the relaxed state, e.g. after removal from the weaving loom, and preferably without any post-weaving treatments such as washing, shrinking, sanforizing, mercerizing, or finishing. Preferably, after taking the fabric from the loom, it is allowed to relax naturally under ambient temperature and humidity for at least 24 hours, laid flat and unrestrained, to remove residual tensions from the weaving process. This "off-loom, relaxed" condition reflects the actual woven structure before any dimensional changes introduced by wet or thermal finishing processes. Particularly preferred, fabric samples are conditioned in accordance with ISO 139, typically for at least 24 hours at 20°C ± 2°C and 65% ± 4% relative humidity, before measuring fabric parameters, e.g. yam count and yam density.Although the off-loom relaxed state is the primary measurement reference, depending on the intended use or specification control, On-Loom Conditions or Post-Finishing Conditions could be decisive too. In case of On-Loom Condition, measurements are taken directly on the loom. In case of Post-Finishing Condition, measurements taken after washing, shrinking, or finishing may reflect end-use dimensions, especially for garments or home textiles. With respect to washing, the measurement could be made after standard wash cycle according to ISO 6330.

[0022] In an embodiment of the first aspect, the first set of warp yarns has a warp yam density of less than 20 warps / cm, preferably less than 18 warps / cm, more preferably less than 16 warps / cm, most preferably less than 14 warps / cm, and / or of at least 6 warps / cm, preferably at least 8 warps / cm, more preferably at least 10 warps / cm, most preferably at least 12 warps / cm. The inventors have found that the upper boundary ensures that the coarse warp yam system is present in a density range that balances structural function and aesthetic contribution. In particular, densities below 20 warps / cm reduce fabric weight and improve drape and softness, while still retaining enough surface definition through the bulk of the coarse yams. The lower limit, in particular of at least 6 warps / cm, ensures that the fabric retains coherent structure and does not suffer from open gaps or excessive slippage, especially where the secondary warp system is not yet fully compensatory. The narrower preferred ranges (e.g., 10-14 warps / cm) provide practical design guidance for optimizing between heavy appearance, low weight and structural integrity of the fabric.

[0023] A warp yam density of 10 to 14 warps / cm is especially preferred when the yam count of the first set of warp yams lies in a range of 750-850 dtex. Densities below 12 warps / cm are advantageous for softer, more drapey fabrics, such as those intended for lounge or fashion garments. For applications where a stiffer, more structured fabric is desired (e.g., outerwear or jeans), densities near the upper end of the range (16-18 warps / cm) may be used.

[0024] A second aspect of the invention, which may be combined with the first aspect and its embodiments and vice versa, relates to a fabric, comprising a first set of warp yams, in particular comprising staple fibers, and a second set of warp yams, in particular comprising synthetic filaments, wherein the warp yams of the second set of warp yamshave a lower yarn count than the warp yams of the first set of warp yams, wherein the first set of warp yams has a count-density, which can be calculated by multiplying the warp yam density of the first set of warp yams with the yam count of the warp yams of the first set of warp yams, of less than 18,000 dtex / cm. Preferably, the fabric is a woven fabric. In particular, the second aspect introduces the count-density as a combined metric that reflects both the yam fineness (yam count) and the yam density (threads per cm) of the first warp yam set. In particular, the count-density expresses the mass of warp yams per fabric width unit, in particular in weft direction, providing a more nuanced control parameter than either yam count or density alone. Limiting the countdensity of the first warp set to below 18,000 dtex / cm ensures that the overall warp yam mass remains low, despite the use of coarse yams, thus contributing directly to reduced fabric weight of a fabric heaving heavy appearance. In particular, this allows coarse yams to be used at relatively low densities without exceeding mass thresholds, facilitating the visual heaviness and textile bulk without undermining comfort and drapability.

[0025] The term “count-density” may also be referred to as linear mass density per unit width, or warp yam linear weight concentration. The feature „count-density, which can be calculated by multiplying the warp yam density of the first set of warp yams with the yam count of the warp yams of the first set of warp yams, of less than 18,000 dtex / cm, may alternatively be phrased in that „the total linear density per unit width of the warp yams of the first set of warp yams is less than 18,000 dtex / cm.”

[0026] The term „count-density“ as used herein may be calculated by multiplying yam count and warp yam density, e.g. by the following formula:

[0027] count-density (dtex / cm) = Yarn count (dtex)xWarp yarn density (yarns / cm)

[0028] For example, coarse yams with a yam count of 800 dtex and a warp yam density of 20 yarns / cm would have a count-density of 1.600 dtex / cm (800x20=16,000 dtex / cm).

[0029] Preferably, the first set of warp yams may have yam counts between 700-900 dtex, with densities adjusted to stay below the 18,000 dtex / cm threshold. For example, a yam of 850 dtex may be used at a density of up to 21 warps / cm; a coarser 1000 dtex yam would need to be used at a maximum of 18 warps / cm to satisfy the limit. Theseconfigurations allow tailoring the heavy appearance and weight of a fabric, while the contribution of structural integrity is supported by the second warp set.

[0030] In an embodiment of the second aspect, the first set of warp yams has a count-density of less than 17,000 dtex / cm, preferably less than 15,000 dtex / cm, more preferably less than 13,000 dtex / cm, even more preferably less than 12,000 dtex / cm, most preferably less than 11,500 dtex / cm, and / or of at least 6,000 dtex / cm, preferably at least 8,000 dtex / cm, more preferably at least 9,500 dtex / cm, even more preferably at least 10,500 dtex / cm, most preferably at least 11,000 dtex / cm. This particularly provides a refined set of upper and lower boundaries for the count-density of the first warp yam system, ensuring the fabric achieves an optimal balance between low weight, mechanical integrity and heavy appearance. A count-density below 17,000 dtex / cm (especially below 12,000 dtex / cm) particularly helps to limit fabric mass per unit area, which is beneficial for producing lightweight heavy-look fabrics. A minimum count-density of at least 6,000 dtex / cm ensures a sufficient amount of material and frictional interface to preserve slippage resistance and dimensional stability, which is particularly beneficial when using lower warp yam densities. The narrower preferred ranges (e.g., 10,500-11,500 dtex / cm) provide a heavy look combined with low weight, while maintaining enough inter-fiber friction to avoid deformation during wear and laundering.

[0031] In particularly preferred embodiments, the first warp yams have a yam count of between 750 and 900 dtex, with warp densities between 12 and 14 warps / cm, yielding count-densities between 9,000 and 12,500 dtex / cm. These ranges have been found to offer an ideal compromise between a visually heavy fabric and a lightweight construction, adequate inter-yarn friction to prevent slippage in typical garment use conditions, and compatibility with standard weaving equipment and industrial yam supply. Additionally, or alternatively, the use of 3 / 1 or 2 / 2 twill weaves for the first warp system has shown particular effectiveness in these ranges, as such patterns maximize yam exposure and visual impact, even at moderate densities.

[0032] A third aspect of the invention, which may be combined with the first and / or second aspect and its embodiments and vice versa, relates to a fabric, comprising a first set of warp yams, in particular comprising staple fibers, and a second set of warp yams, in particular comprising synthetic filaments, wherein the warp yams of the second setof warp yarns have a lower yam count than the warp yams of the first set of warp yams, wherein the second set of warp yams has a warp yam density of at least 8 warps / cm. Preferably, the fabric is a woven fabric. The third aspect particularly introduces a minimum warp yam density for the second set of warp yams, which provides a stabilizing role in the fabric construction. The second set comprises, preferably consists, of finer synthetic filament yams, in particular hidden between the coarser primary warp yams of the first set. A minimum density of 8 warps / cm ensures that the second warp system contributes meaningfully to the binding point density, especially if it is woven in a 1 / 1 plain weave or similarly tight pattern. The increased frequency of interlacing between the second warp yams and the weft yams compensates for the low density of the first warp set, improving dimensional stability, slippage resistance, and tear strength of the fabric. At this density, the second warp system particularly creates a network of internal reinforcement that stabilizes the entire textile structure without interfering with the surface appearance or hand feel.

[0033] The second set of warp yams preferably comprises, more preferably consists of, synthetic filaments, such as polyester or nylon, with yam counts below 150 dtex, preferably below 100 dtex, in particular as further described within the present disclosure. The second warp set is preferably woven in a 1 / 1 plain weave, interleaving with each weft yam to maximize the number of binding points. Particularly preferred, the second warp yam density lies between 10 and 14 warps / cm, which, in combination with fine yam count, ensures structural reinforcement with minimal weight addition and does not visibly alter the fabric surface due to its concealed positioning between the coarse yams.

[0034] The two warp yam systems may be inserted alternately (e.g., coarse-fine-coarse-fine...), or grouped in structured ratios (e.g., 1 coarse to 1 fine), depending on the desired balance between fabric stiffness, drape, and process compatibility.

[0035] In an embodiment of the third aspect, the second set of warp yams has a warp yam density of at least 9 warps / cm, preferably at least 10 warps / cm, more preferably at least 11 warps / cm, even more preferably at least 12 warps / cm, most preferably at least 13 warps / cm, and / or of less than 50 warps / cm, preferably less than 40 warps / cm, more preferably less than 30 warps / cm, even more preferably less than 20 warps / cm, mostpreferably less than 15 warps / cm. This provides refined lower and upper bounds for the warp yam density of the second set of warp yams, offering a precisely controllable design range to balance mechanical reinforcement and fabric softness and flexibility. In particular, the increased minimum value of at least 9 warps / cm) improve binding point density, especially when the second warp yams are woven in a tight interlacing pattern (e.g., 1 / 1 plain weave), enhancing slippage resistance and dimensional stability. The upper limits of less than 50 warps / cm, preferably less than 15 warps / cm ensure the fabric does not become overly stiff or dense, which would negatively affect drape, softness, or breathability. These ranges allow the designer to fine-tune the influence of the second warp system depending on the primary warp density, yam counts, and target application (e.g., lightweight shirting vs. structured denim-like fabrics).

[0036] A preferred warp yam density of the second set of warp yams between 10 and 14 warps / cm has been shown to provide sufficient interlacing frequency for mechanical reinforcement, limited impact on weight and fabric thickness, and excellent compatibility with fine synthetic yams in the range of 50-100 dtex. For instance, a fine warp yam density of 12 warps / cm with 70 dtex yams contributes a count-density of 840 dtex / cm, which significantly enhances the internal binding structure. In fabrics where maximum softness is desired, a fine warp yam density of 10-11 warps / cm provides a good balance between support and drape. It is also preferred that the second warp yams interlace in a weave pattern that differs from the first warp set (e.g., plain vs. twill), as this increases the distribution of binding points and prevents alignment of float zones, thus improving slippage resistance.

[0037] A fourth aspect of the invention, which may be combined with the first, second and / or third aspect and its embodiments and vice versa, relates to a fabric comprising a first set of warp yams, in particular comprising staple fibers, and a second set of warp yams, in particular comprising synthetic filaments, wherein the warp yams of the second set of warp yams have a lower yam count than the warp yams of the first set of warp yams, wherein the second set of warp yams has a count-density, which can be calculated by multiplying the warp yam density of the second set of warp yams with the yam count of the warp yams of the second set of warp yams, of at least 700 dtex / cm. The „count density of at least 700 dtex / cm“ of the second set of warp yamsmay alternatively be phrased in that the second set of warp yams comprise a combined linear mass per unit fabric width of at least 700 dtex / cm. Preferably, the fabric is a woven fabric. This fourth aspect defines a minimum count-density threshold for the second warp yam system, ensuring that it contributes a sufficient degree of structural support to the woven fabric despite using fine (low-count) yams. Introducing a countdensity threshold ensures that the total linear mass per unit width of the second warp set reaches a level that contributes meaningfully to the binding point density, slippage resistance, and dimensional stability of the fabric. The threshold of 700 dtex / cm ensures that, even with very fine yams (e.g., 70 dtex), the warp density is sufficient (e.g., >10 warps / cm) to provide structural integrity. This particularly enables the visual heaviness and low weight of the fabric, by offsetting the structural weakness of the coarse, low-density first warp set through high-frequency fine interlacings, in particular forming an ..invisible reinforcing grid".

[0038] The second warp yams preferably have a yam count between 50 dtex and 100 dtex. and are used at a density of at least 10 warps / cm, more preferably between 11 and 13 warps / cm, yielding a count-density range of 700-1300 dtex / cm. Such configuration particularly ensures increased number of binding points per cm2(especially when woven in plain weave), low visual impact, as fine yams remain hidden beneath the coarse warp system, and minimal addition to overall fabric weight, maintaining the lightweight nature of the invention.

[0039] In an embodiment of the fourth aspect, the second set of warp yams has a countdensity of at least 750 dtex / cm. preferably at least 800 dtex / cm. more preferably at least 900 dtex / cm. even more preferably at least 950 dtex / cm. most preferably at least 1.000 dtex / cm. and / or of less than 6,000 dtex / cm. preferably less than 3,000 dtex / cm. more preferably less than 1,500 dtex / cm. even more preferably less than 1,300 dtex / cm. most preferably less than 1.100 dtex / cm. These defined ranges allow precise control over the mechanical reinforcement provided by the fine synthetic yams, while avoiding excessive material use and stiffness. A minimum count-density of 750-1.000 dtex / cm ensures that the second warp system provides sufficient internal interlacing strength, which is particularly beneficial when the first warp system has a low warp yam density. The upper limits, capped at 1,100-6,000 dtex / cm. prevent the auxiliary warp system from becoming overly dense, which would increase fabric weight

[0040] -io-unnecessarily, stiffen the structure, or even obscure the intended appearance and drape of the fabric. This range allows for structural integrity with lightweight fine filaments, while keeping the stabilizing system non-intrusive and hidden beneath the fabric surface.

[0041] Preferably, the second set of warp yams has a count-density between 750 and 1,100 dtex / cm, more preferably between 800-1 ,000 dtex / cm. In a preferred embodiment, the second set of warp yams comprise, in a particular consist of, 70-90 dtex synthetic filament yams (e.g., polyester) used at warp density between 10 and 14 warps / cm, in particular yielding a count-densities between 700 and 1,300 dtex / cm. Count-densities above 1 ,100 dtex / cm may be used where extremely high structural rigidity is required, such as in technical fabrics or upholstery, but are less preferred for garments due to reduced flexibility and comfort.

[0042] In an embodiment of any of the previously described aspects of the invention or their embodiments, the warp yams of the second set of warp yams have a yam count of less than 400 dtex, preferably less than 200 dtex, more preferably less than 150 dtex, even more preferably less than 110 dtex, most preferably less than 90 dtex, and / or of at least 20 dtex, preferably at least 35 dtex, more preferably at least 50 dtex, even more preferably at least 60 dtex, most preferably at least 70 dtex.

[0043] This embodiment introduces a defined yam count range for the second set of warp yams, i.e. , the fine stabilizing warp system that complements the coarse, lower-density first warp set. This range ensures that the second warp system is composed of yams, e.g. synthetic filaments, that are significantly finer than the coarse staple yams of the first warp set, as per the inventive concept, that the fabric remains lightweight and minimally intrusive, contributing to internal structural integrity without affecting the appearance, weight, or hand feel of the fabric surface and provides sufficient binding capacity per unit area when used at yam densities and / or count-density ranges of the second set of warp yams as specified herein. The combined result is a lightweight fabric with a heavy appearance, structurally stabilized by a virtually invisible fine warp network.

[0044] In particular in this embodiment, the second warp yams are preferably synthetic continuous filaments, e.g., polyester or nylon, with yam counts between 60 and 100dtex, more preferably 70-90 dtex, which particularly leads to high tensile strength and low elongation, to resist deformation and contribute to binding point stability.

[0045] In an embodiment of any of the previously described aspects of the invention or their embodiments, the yam count of the warp yarns of the first set of warp yams is at least 200 %, preferably at least 400 %, more preferably at least 600 %, even more preferably at least 800 %, most preferably at least 1 ,000 %, larger than the yam count of the warp yams of the second set of warp yams and / or less than 3,000 % larger, preferably less than 2,500% larger, more preferably less than 2,000 % larger, even more preferably less than 1 ,500 % larger, most preferably less than 1 ,200 % larger, than the yam count of the warp yams of the second set of warp yams. This embodiment introduces a proportional relationship between the coarse first warp yams and the fine second warp yams, ensuring that first warp yams dominate the surface appearance and visual structure of the fabric due to their significantly higher linear density (thicker yams), while the second warp yams remain hidden, acting as a structural stabilizer that contributes binding points without altering the fabric’s look or feel. By setting the yam count of the first set to be at least 200%, preferably at least 400 % or 600%, larger than that of the second set, the invention ensures a clear functional and visual separation between the two systems. Limiting the ratio to less than 3,000%, preferably 1,200%, ensures that the second set still provides enough material mass per cm to have a meaningful structural effect.

[0046] The expression that a yam count of the warp yams of the first set of warp yams is larger than the yam count of the warp yams of the second set of warp yams count could alternatively be phrased in that the yam count of the warp yams of the first set of warp yams is between x and y, e.g. 2* and 30x, the yam count of the warp yams of the second set of warp yams, preferably between 6* and 12*. ”

[0047] In this embodiment, the coarse warp yams preferably have a yam count between 800-900 dtex (e.g., cotton staple), wherein the second warp yams have a yam count between 70-90 dtex (e.g., polyester filament), in particular in that yam count of the coarse warp yams is 800-900% larger than the yam count of the fine warp yams, which particularly ensures that the coarse yams define the fabric’s visual and tactilequalities, while the fine yarns invisibly support structural cohesion, maximizing the aesthetic-to-weight performance ratio of the fabric.

[0048] In an embodiment of any of the previously described aspects of the invention or their embodiments, the warp yams of the first set of warp yams comprise, preferably consist of, staple fibers, preferably cotton fibers.

[0049] This embodiment particularly defines that the first warp yams, which form the visually dominant and structurally coarser layer of the woven fabric, are made of staple fibers, with cotton being the preferred material. The use of staple fibers, especially cotton, offers several advantages in the context of the invention, such as visual and tactile bulk (staple fiber yams tend to be more voluminous and textured than filament yams, enhancing the “heavy look” of the fabric), surface coverage (Their hairy and fibrous character helps conceal the fine synthetic yams of the second warp set, preserving the desired appearance), comfort (Cotton offers excellent skin feel, moisture absorption, and breathability, making it suitable for direct-to-skin applications) and process compatibility (Cotton yams are well-suited for twill weaves, commonly used in denim, workwear, and casual garments).

[0050] By optionally limiting the composition to “consist of’ staple cotton fibers, this embodiment allows the first warp system to function as the aesthetic and mechanical base of the fabric, in line with the inventive concept.

[0051] The expression “staple fibers” particularly refer to fibers of finite length (as opposed to continuous filaments), which may be natural, regenerated, or synthetic in origin.

[0052] The coarse yams may comprise, in particular consist of, ring-spun yams, in particular ring-spun cotton yams (preferred for softness and strength) or open-end or compact spun yams (depending on the intended handfeel and surface character). Additionally, or alternatively, the coarse yams may comprise or consist of blends, for example blends of cotton with 10-20% polyester, which may be used to improve dimensional stability, reduce shrinkage, or enhance abrasion resistance in garments, while still retaining the visual and tactile characteristics of cotton. Additionally or alternatively, the coarse yams may be woven with the weft yams as twill weave (e.g., 3 / 1 , 2 / 2), enablinglonger surface floats for the coarse yams to define the fabric’s visual texture, while the second warp set handles structural reinforcement.

[0053] In an embodiment of any of the previously described aspects of the invention or their embodiments, the warp yams of the second set of warp yams comprise, preferably consist of, filaments, and / or comprise, preferably consist of, synthetic material, preferably polyester or nylon, most preferably polyester. The use of synthetic continuous filaments, particularly polyester, offers several advantages directly supporting the invention’s technical goals. Their high linear strength at very low yam counts enables the use of fine yams with strong structural contribution, increasing binding point density without adding bulk. Their low elongation ensures that these yams anchor the fabric and prevent slippage, especially under stress (movement, laundering). Their smooth filament surfaces allow them to remain unnoticeable in the fabric surface, hidden beneath the coarse first warp set thereby preserving the desired “heavy look”. Their durability, resistance to moisture, and shape retention make synthetic filaments especially suited for reinforcement roles in multi-component fabric constructions.

[0054] The expression “comprise filaments” particularly permits partially filamentous structures, such as core-sheath or wrapped yams. The expression ..consist of filaments” particularly restricts the second warp yams to 100% continuous filament yams monofilament or multifilament. The expression ..comprise synthetic material” particularly includes a broad range of polymers, such as polyester (preferred), nylon (polyamide), polypropylene, polyethylene, or elastomeric filaments. The use of polyester is most preferred in view of its high modulus, thermal and chemical resistance, wide availability in fine dtex counts (e.g., 70-90 dtex), and excellent compatibility with cotton warp systems.

[0055] In this embodiment, the fine warp yams preferably comprise, in particular consist of. multifilaments, preferably multifilament polyester (e.g., 34-filament, low-denier per filament yams), for high flexibility and minimal surface visibility. Alternatively, low-denier monofilaments may be used for stiffer applications. Preferably additionally, the yam count of the fine warp yams is between 60 and 100 dtex. more preferably 70-90 dtex. Preferably additionally, the fine warp yams are woven in a 1 / 1 plain weave, inparticular to maximize the binding points. Preferably additionally, the fine warp yams are interleaved between the coarse warp yams, in particular to form an internal stabilizing grid. Preferably additionally, the fine warp yams have a tensile strength of at least 2,5 cN / dtex, an elongation at breack of less than 20% and a moisture regain of less than 1 %. For performance fabrics (e.g., workwear or technical textiles), nylon filaments may be preferred for enhanced abrasion resistance. For sustainability-focused products, recycled polyester (rPET) filaments may be used.

[0056] In an embodiment of any of the previously described aspects of the invention or their embodiments, the warp yams of the first set of warp yams and weft yams of the fabric interlace in a pattern differing from a 1 / 1 plain weave, wherein the pattern is preferably a twill weave, a satin weave or a basket weave, preferably a twill weave, most preferably a 3 / 1 twill weave. Alternatively, it could be said that the coarse warp yams are woven in a pattern that reduces the frequency of interlacing with the weft compared to the fine yams, such as a twill or satin weave, in particular thereby enhancing surface visibility and bulk.

[0057] This embodiment particularly specifies that the coarse warp yams, which particularly provides the fabric’s visual and tactile identity, is woven not in plain weave, but in a pattern with fewer interlacing’s, such as twill, satin, or basket weave. The choice of a non-plain weave, and in particular a twill weave, has multiple functional effects: It’s lower interlacing frequency results in longer floats of the coarse warp yams on the surface, allowing them to dominate the fabric appearance and provide the desired “heavy look.” Patterns like 3 / 1 twill (one interlace every four picks) reduce the number of binding points contributed by the first warp system, which is intentional — the second warp system compensates for this structurally. Twill weaves allow for better drapability than plain weaves, despite their structured appearance. The diagonal surface effect of twill enhances the textile aesthetics, typical of fabrics like denim, chino, or workwear.

[0058] In this embodiment, the coarse warp yam preferably floats over three weft yams, then under one. Alternative, the coarse warp yams may be woven in a 2 / 2 twill (balanced look and drape), a 4-end satin (higher luster and smoother hand) or in a basket weaves (chunky, textured surface, but limited structural control).In an embodiment of any of the previously described aspects of the invention or their embodiments, the warp yams of the second set of warp yarns and weft yams of the fabric interlace in a pattern of a 1 / 1 plain weave and / or in a pattern differing from the pattern in which the warp yams of the first set of warp yams and weft yams of the fabric interlace with each other, preferably in a pattern with more, preferably at least 50 % more, more preferably at least 100 % more, binding points than the pattern in which the warp yams of the first set of warp yams and weft yams of the fabric interlace with each other. Alternatively, it could be said that, the second warp yams interlace with the weft more frequently than the first warp yams do. As a further alternative, it could be said that the two warp sets are woven with different patterns, wherein their binding point contributions are asymmetrical, i.e., the second warp yams primarily ensure mechanical integrity, while the first warp yams provide aesthetic and tactile characteristics.

[0059] This embodiment particularly defines that the fine yams are interlaced with the weft yams in a tighter weave pattern than that of the first (coarse) warp yams, preferably 1 / 1 plain weave, which maximizes binding point frequency. This allows the fine warp yams to act as an internal stabilizing grid, compensating for the lower interlacing frequency of the first set (e.g., twill weave). The fine warp yams creates more interlacing points per cm2than the first warp set — ideally at least 50% more, most preferably 100% or more, thereby significantly increasing the overall binding point density of the fabric. This setup prevents warp / weft slippage and enhances dimensional stability, even at low total warp densities and with reduced fabric weight.

[0060] The expression “pattern with more binding points” particularly means that, per unit area, the second warp set forms a denser interlacing structure with the weft than the first warp set. The second warp yams may Be woven in 1 / 1 plain weave (1 over, 1 under) or in any pattern that results in greater interlacing frequency than the coarser warp yams (e.g., 2 / 2 twill vs. 3 / 1 twill).

[0061] In an embodiment of any of the previously described aspects of the invention or their embodiments, the weft yams have a weft yam density of at least 6 wefts / cm, preferably at least 8 wefts / cm, more preferably at least 10 wefts / cm, even more preferably at least 12 wefts / cm, most preferably at least 14 wefts / cm, and / or of less than 50 wefts / cm,preferably less than 30 wefts / cm, more preferably less than 20 wefts / cm, even more preferably less than 18 wefts / cm, most preferably less than 16 wefts / cm.

[0062] This embodiment introduces the density of the weft yam system, a structural element that interacts with both warp yam sets to generate binding points and control the fabric's mechanical integrity, handle, and dimensional performance. A minimum weft density of 6-14 wefts / cm ensures that sufficient interlacing opportunities are available to support both warp systems which is particularly important where the first warp system is low in density and the second system must stabilize the fabric. An upper limit of 16 wefts / cm particularly prevents over-tightening of the fabric, preserving softness and drape, lightweight construction, breathability, and the intended low-mass feel of the product. Thus, this weft density range is tuned to maximize binding point efficiency while minimizing mass. Most preferred, the weft yam density is between 12 and 16 wefts / cm, especially in garments where structure and drape must be balanced. For soft fabrics, weft densities of 10-12 wefts / cm may be preferred, while 14-16 wefts / cm offer greater structural Integrity and recovery.

[0063] In an embodiment of any of the previously described aspects of the invention or their embodiments, the weft yams have a count-density, which can be calculated by multiplying the weft yam density of the weft yams with the yam count of the weft yams, of less than 25,000 dtex / cm, preferably less than 18,000 dtex / cm, more preferably less than 15,000 dtex / cm, even more preferably less than 14,000 dtex / cm, most preferably less than 13,500 dtex / cm, and / or of at least 8,000 dtex / cm, preferably at least 10,000 dtex / cm, more preferably at least 11 ,000 dtex / cm, even more preferably at least 12,000 dtex / cm, most preferably at least 12,500 dtex / cm.

[0064] This embodiment introduces a count-density of the weft yams, in particular a structural metric that reflects the mass of weft material per unit fabric width. Like the warp countdensity disclosed herein, count-density of the weft yams may be used to balancing fabric weight, structural stability, and binding point performance. A minimum countdensity (>8,000 dtex / cm) particularly ensures that there is sufficient weft material to properly engage with both warp systems, generate enough binding points, and provide the transverse reinforcement needed for mechanical integrity. A maximum countdensity (<25,000 dtex / cm, preferably <13,500 dtex / cm) particularly ensures the fabricremains lightweight, flexible, and does not become overly stiff or heavy from excessive weft insertion. This embodiment enables designers to control weft contribution to fabric structure without specifying absolute yam size or pick.

[0065] In this embodiment, the count-density of the weft yarns is preferably between 12,000 and 13,500 dtex / cm, which is particular advantageous for generating high binding point density in combination with second warp yarns, maintaining fabric softness, drape, and low weight. Such count density can be realized for example with weft yams having a yam count between 800-1000 dtex and a weft yam density of 12-14 wefts / cm. Fabrics in such range particularly feel light yet robust, exhibit minimal slippage and are suitable for apparel, home textiles, and durable fashion fabrics.

[0066] In an embodiment of any of the previously described aspects of the invention or their embodiments, the weft yams comprise, preferably consist of, yams with a yam count of at least 200 dtex, preferably at least 400 dtex, more preferably at least 600 dtex, even more preferably at least 700 dtex, most preferably at least 800 dtex, and / or less than 2,000 dtex, preferably less than 1 ,500 dtex, more preferably less than 1 ,200 dtex, even more preferably less than 1 ,000 dtex, most preferably less than 900 dtex.

[0067] The lower limit (>200 dtex) particularly ensures that the weft yams contribute sufficient mass and surface area to engage effectively with the warp yams, especially the coarse first warp system, which floats over multiple picks in low-binding-point patterns like twill. The upper limit (<900-2,000 dtex) particularly prevents the weft yams from being too bulky or rigid, which would impair drape and handfeel, increase fabric weight beyond the goals of the invention, and interfere with the “lightweight-heavy look” combination. Thus, this embodiment particularly ensures that the weft yams contribute appropriately to both visual texture and mechanical performance, within a targeted weight envelope.

[0068] The weft yams can be of any yam type, e.g. staple fiber yam, filament yam or mixtures thereof, can be produced by any yam producing method, e.g. ring spinning or open-end spinning, and comprise or consist of any material, e.g. natural fibers, such as cotton, or synthetic fibers, such as polyesters.

[0069] In an exemplary embodiment of any of the previously described aspects of the invention or their embodiments, the weft yams comprise, in particular consist of, staplefibers, in particular cotton fibers. This embodiment introduces the material and structure of the weft yams, aligning them with the aesthetic and tactile properties of the coarse first warp yams and supporting the invention’s goal of achieving a heavy visual appearance with soft and flexible performance. Using staple fibers, particularly cotton, in the weft contributes to the natural, voluminous surface texture and traditional look often associated with heavy woven fabrics like denim, twill, and canvas. Staple fiber weft yams are particularly preferred in combination with staple fiber coarse yams for enhancing interlacing stability with both warp systems. This composition reinforces the design intent: to simulate the appearance of heavy-weight fabrics using natural, familiar materials, while lightening the structure internally through the second warp yam system. In particular in this embodiment, the weft yams may consist to 100 % cotton fibers, or may be comprise cotton-rich blends, e.g. comprising at least 80 wt.-% of cotton in combination with another fiber, such as polyester, e.g. 20 wt.-% polyester. The weft yams may comprise or consist of ring-spun yams and / or open-end spun yams. However, as described above, the use of cotton fibers for the weft yam is only exemplary. The weft yams can be made of any type, produced by any method and comprise or consist of any material.

[0070] In an embodiment of any of the previously described aspects of the invention or their embodiments, the ratio of the warp yam density of the first set of warp yams to the warp yam density of the second set of warp yams is less than 2 / 1. Alternatively, it could be said that the first warp yams are inserted at no more than twice the frequency of the second warp yams, in particular ensuring that the structural function of the second warp set is preserved. This embodiment establishes a maximum allowable ratio between the warp yam densities of the first set of warp yams (coarse staple yams) and the second set of warp yams (fine filament yams). A ratio of less than 2:1 ensures that the second warp yam system is sufficiently dense to provide structural stability, contribute a high number of binding points, and compensate for the reduced interlacing frequency of the first warp system (e.g., in 3 / 1 twill or similar patterns. This ratio promotes achieving, the invention’s ability to achieve a low overall fabric weight, a heavy fabric appearance (from the coarse warp yams), and a high slippage resistance (from the fine warp yams). By limiting the warp density imbalance, the claim ensures that the stabilizing warp system is not underrepresented in the structure. Maintaininga ratio under 2 avoids over-dominance of the coarse yarns, which could lead to slippage, open structure, or dimensional instability if not properly reinforced.

[0071] The Warp Density Ratio may be calculated as follows:

[0072] Warp Density of first warp yarns / warp density of second warp yarns

[0073] If the second set of warp yams has the same or higher warp density than the first set of warp yams, the ratio is <1 , which is even more preferred.

[0074] In one embodiment, the ratio is between 1.0 and 1.5, in particular to ensure that the coarse yams dominate visually (lower density, larger diameter), while the fine filaments stabilize the structure.

[0075] In an embodiment of any of the previously described aspects of the invention or their embodiments, the ratio of the warp yam density of the first set of warp yams to the warp yam density of the second set of warp yams is 7 / 4 or less, preferably 5 / 3 or less, more preferably 3 / 2 or less, most more preferably 1 / 1 or less, and / or 1 / 5 or more, preferably 1 / 4 or more, more preferably 1 / 3 or more, most preferably 1 / 2 or more. Alternatively, it could be said that the warp yams of the first set are inserted at a frequency no greater than 7 / 4 and no less than 1 / 5 that of the second warp yams, preferably close to or equal to 1 / 1. This embodiment defines a specific design window for the relative warp densities of the first (coarse) and second (fine) warp yam sets. The defined ratios ensure that the coarse warp system remains dominant in appearance, while the fine warp system maintains a structurally effective presence, the range captures both ends of the possible configurations, wherein ratios < 7:4 (1.75) limit overrepresentation of the first warp set, while ratios > 1 :5 (0.2) prevent the second warp set from dominating or overwhelming the visual and mechanical profile. The core inventive structure benefits from relative parity or mild imbalance between warp systems, typically ranging from 1:2 to 3:2.

[0076] In this embodiment, the first and second set of warp yams may have equal warp densities (ratio = 1:1), fine warp yam dominated structures (ratio <1:1) or coarse warp yam dominated structures (2 / 1 > ratio > 1:1). These ratios allow low total yam count, maintaining fabric weight reduction goals, high structural cohesion, due to theincreased interlacing of the second warp system, and preservation of the heavy surface look, as fine yarns remain invisible below the coarse surface. Ratios below 1 are particularly preferred when the second warp set is woven in plain weave, significantly increasing the binding point density.

[0077] In an embodiment of any of the previously described aspects of the invention or their embodiments, the ratio of the warp yarn density of the first set of warp yams to the warp yam density of the second set of warp yams is selected from 3 / 2, 5 / 3, 7 / 4, 1 / 1, 2 / 3, 3 / 5, 4 / 7, 2 / 1 and 3 / 1, preferably selected from 1 / 1, 2 / 3, 3 / 5, 4 / 7, 2 / 1 and 3 / 1, more preferably selected from 1 / 1, 2 / 1 and 3 / 1, even more preferably selected from 1 / 1 and 2 / 1 , most preferably is 1 / 1.

[0078] This embodiment introduces a set of discrete warp density ratios, each of which reflects a balanced or functionally optimized relationship between the coarse (first) warp yams and the fine (second) warp yams. These ratios provide practical design templates that balance structural reinforcement (via the second warp set), with visual dominance and aesthetic control (via the first warp set). This embodiment reflects the inventor's observation that absolute ratios are less important than the correct proportional presence of each warp system. The ratios offer ready-to-implement construction rules for fabric designers and weavers working within the invention's parameters. The most preferred embodiment makes use of a ratio of 1 / 1 , which is ideal when both warp sets are set at the same density (e.g., 12 / 12 cm), giving balanced structure and interlacing grid.

[0079] In an embodiment of any of the previously described aspects of the invention or their embodiments, the fabric has a binding point density of at least 3,500 binding points / gram. This embodiment particularly introduces the number of binding points per gram of fabric, which particularly reflects how efficiently the fabric converts mass into structural stability. A value of > 3,500 binding points / gram means the fabric achieves a high degree of interlacing cohesion relative to its weight, demonstrates superior slippage resistance, dimensional stability, and durability, while remaining lightweight and soft. This feature is particularly beneficial in light fabrics with low warp and weft densities, where structural weaknesses would normally arise. The high binding pointdensity per unit mass shows that such weaknesses have been eliminated by intelligent construction, not brute material quantity.

[0080] The binding point density per gram can be calculated as follows:

[0081] Binding Points / cm2x 10,000

[0082] Binding Points / Gram = - = - Fabric weigth (g / m )

[0083] The parameter ..Binding Points / cm2“ particularly refers to the sum of binding points contributed by both warp systems, in particular as disclosed herein. The parameter ..Fabric weight" particularly refers to the weight of a fabric in gram per square meter fabric. Preferably, the binding points / cm2or the binding points I gram are measured in a off-loom, relaxed stated of the fabric, in particular as described above.

[0084] In the context of the present invention, a binding point (also referred to as a connection point) is in particular defined as a structural interlacing location in the woven fabric where a warp yam engages with a weft yam. forming a mechanical intersection comprising an over portion and an under portion. In particular, unlike counting every crossing of warp and weft as a binding point, the present invention counts one full interlacing cycle comprising one over portion and one under portion as one binding point. In particular, the number of binding points per unit area (binding points / cm2) is calculated using the following formula:

[0085] Binding Points / cm2= (Warp Yarn Density xWeft Yarn Density ) / F,

[0086] Wherein “F” means ..weave factor”. In particular, the weave factor is defined as the number of weft yams over which a warp yam must pass to complete one full interlacing cycle comprising one over portion and one under portion or vice versa. This factor particularly reflects the structural repeat of the weaves and is used to calculate the effective number of binding points per square centimeter. For example, in a plain weave, every warp interlaces with every weft in alternating order so that a warp yam must pass two weft yams to complete one full interlacing cycle comprising one over portion and one under portion so that the weave factor F is 2. In another example of a 3 / 1 weave, a warp yam must pass three weft yams to form an over portion and one weft yam to form an under portion or vice versa so that, in total, four weft yams arepassed to complete one full interlacing cycle comprising one over portion and one under portion so that the weave factor F is 4. In other words, for a fabric made from one set of warp yams and one set of weft yams in a 1 / 1 weave, the binding points / cm2could be calculated as Warp Density x Weft Density x 0.5 (weave factor F of the 1 / 1 weave). For a fabric made from one set of warp yams and one set of weft yams in a 3 / 1 weave, the binding points / cm2could be calculated as follows as Warp Density x Weft Density x 0.25 (weave factor of the 3 / 1 weave). In a fabric according to the invention, for example a first set of warp yams woven in a 3 / 1 weave with weft yams and a second set of warp yams in 1 / 1 weave with weft yams, the binding points / cm2can be calculated as warp density of first warp yams x weft density x 0,25 (weave factor F of 3 / 1 weave) + warp density of second warp yams x weft density x 0,5 (weave Factor F of 1 / 1 weave). In other words, in embodiments with multiple sets of warp yams and one set of weft yams, the binding points I cm2is preferably calculated by addition of the binding points / cm2of each warp yam set with the respective weft yams.

[0087] In preferred embodiments, the first warp yam system (coarse yams) is typically woven in a twill or similar pattern with lower interlacing frequency, contributing fewer binding points, wherein the second warp yam system (fine synthetic filaments) is typically woven in a plain weave pattern, increasing the total number of binding points substantially, and thereby compensating for the open structure of the coarse yams. The calculated total number of binding points per cm2, and / or per gram of fabric, is a quantitative indicator of the fabric’s structural stability and slippage resistance, and can be used as a design control parameter.

[0088] In an embodiment of any of the previously described aspects of the invention or their embodiments, the fabric has a binding point density of at least 3,900 binding points / gram, preferably of at least 4,300 binding points / gram, more preferably of at least 4,600 binding points / gram, even more preferably of at least 4,800 binding points / gram, most preferably of at least 4,900 binding points / gram, and / or of less than 10,000 binding points / gram, preferably less than 9,000 binding points / gram, more preferably less than 8,000 binding points / gram, even more preferably less than 7,000 binding points / gram, most preferably less than 6,000 binding points / gramThis embodiment defines an optimized structural efficiency window for the invention — the number of interlacing binding points per gram of fabric — with both minimum and maximum thresholds. A minimum of 3,900-4,900 binding points / gram ensures very high interlacing efficiency per unit mass, excellent slippage resistance, strong dimensional stability with minimal material usage, and good performance in lightweight apparel, soft furnishings, or durable yet flexible fabrics. The maximum of 6,000-10,000 binding points / gram avoids overly tight constructions that increase fabric stiffness, reduce drape and comfort, and can negatively impact aesthetic goals (e.g., too flat or rigid surfaces). This embodiment particularly provides a good compromise of balance between weight reduction, structural performance, and tactile quality.

[0089] In this embodiment, the binding point density per cm2is preferably between 140-160, which can for example be achieved with the first warp yams in a 3 / 1 twill weave, the second set of warp yams n a 1 / 1 plain weave, and a warp density of 12 to 14 warp yarns / cm for both, the first set of warp yams and the second set of warp yams, preferably in combination with a fabric weight of 290 to 330 g / m2, in particular with a binding point density of between 4.500 and 5.000 binding points per gram.

[0090] In an embodiment of any of the previously described aspects of the invention or their embodiments, the fabric has at least 80 binding points / cm2, preferably at least 100 binding points / cm2, more preferably at least 115 binding points / cm2, even more preferably at least 130 binding points / cm2, most preferably at least 145 binding points / cm2, and / or less than 300 binding points / cm2, preferably less than 250 binding points / cm2, more preferably less than 200 binding points / cm2, even more preferably less than 180 binding points / cm2, most preferably less than 160 binding points / cm2. The expression “binding point density" may also be referred to as total interlacing frequency per square centimeter, structural interlacing density, or binding point area coverage.

[0091] This embodiment particularly defines the absolute binding point density per surface area, i.e. , how many warp-weft interlacings occur in 1 cm2of fabric. A minimum of SO-145 binding points / cm2ensures excellent dimensional stability, high slippage resistance, and good tear and tensile performance, even at reduced fabric weight. An upper limit of 160-300 binding points / cm2avoids excessive interlacing that wouldincrease stiffness, reduce drape and softness and drive up material consumption without further benefit. The range between the lower limit and the upper limit has been found to represent a beneficial balance between openness and cohesion that allows the fabric to be light yet visually dense and mechanically strong.

[0092] In this embodiment, the binding point density is most preferably between 115 and 145 binding points I cm2which can be achieved for example with a first set of warp yarns with a 3 / 1 will weave and a warp density of 12 to 14 warps / cm, a second set of warp yarns with a 1 / 1 plain weave and a warp density of 12 to 14 warps / cm and a weft density of 14 to 16 wefts / cm. Such configuration particularly provides high-performance lightweight woven fabrics for apparel and heavy-look textiles with reinforced internal structure.

[0093] In an embodiment of any of the previously described aspects of the invention or their embodiments, the fabric has a weight of less than 375 gram / m2, wherein the warp yarns of the first set of warp yams have a yarn count of at least 770 dtex. Preferably, the fabric is a woven fabric.

[0094] This embodiment ensures that the fabric visually mimics heavy-weight textiles, through the use of coarse (thick) yams in the first warp set (> 770 dtex), which provide bulk, volume, and surface definition, while actually having a reduced physical weight, by keeping total fabric mass below 375 g / m2. Together, these constraints define a novel fabric category: lightweight in mass but heavy in appearance and performance. The coarse yam count of the first warp set gives the impression of a dense, rugged fabric (e.g., like denim or canvas). The fabric weight threshold ensures wearability, flexibility, and comfort — making the textile suitable for garments, soft furnishings, or multiseason apparel.

[0095] In this embodiment, the fabric weight is preferably between 280 and 340 g / m2, enabling sufficient binding points in combination with low weight, while the yam count of the coarse warp yams is preferably between 770 dtex and 900 dtex, providing visual texture and bulk or heavier textiles.

[0096] In an embodiment of any of the previously described aspects of the invention or their embodiments, the fabric has a weight of less than 350 gram / m2, preferably less than330 gram / m2, and / or of at least 100 g / m2, preferably at least 170 g / m2, more preferably at least 220 g / m2, even more preferably at least 250 g / m2, most preferably at least 280 g / m2. This particularly provides a preferred operating range for the fabric's areal weight, reinforcing the invention’s dual goal of achieving the visual and tactile characteristics of a heavy-weight woven fabric, and delivering actual lightness, softness, and drapability, by constraining mass per unit area. The defined range particularly avoids the fabric to be to stiff or heavy for comfort (> 350 g / m2), excludes fabrics that are too light and structurally weak (< 100-170 g / m2), and promotes designs that look and behave like heavier fabrics, but remain suitable for comfortable apparel, layered wear, or light technical use.

[0097] The fabric weight may be measured in grams per square meter (g / m2) according to ISO 3801 or ASTM D3776, wherein the fabrics, in particular samples, are preferably conditioned, in particular according to ISO 139, in particular with standard temperature and humidity), and in particular Relaxed, i.e. free of tension, and either unfinished or finished using standard textile finishing parameters, depending on product definition, preferably unfinished.

[0098] In this embodiment, the most preferred range relates to a fabric with a fabric weight between 280 g / m2and 330 g / m2, which particularly matches typical weights of midweight twills and workwear, ensures high binding point efficiency and keeps the fabric light, breathable, and drapey, while offering structural strength. In alternative embodiments, the fabric weight is between 170-220 g / m2, which may be applied used for soft, pajama-like woven garments, shirtings with high visual bulk but soft touch, and light outer layers designed to emulate canvas or denim. In yet alternative embodiments, the fabric weight is between 330-350 g / m2, which can be used preferably for structured fabrics (e.g., jackets, pants and layered garments, structured loungewear, or soft accessories.

[0099] In an embodiment of any of the previously described aspects of the invention or their embodiments, the warp yams of the first set of warp yams have a yam count of at least 790 dtex, preferably at least 810 dtex, most preferably at least 830 dtex, and / or of less than 2,000 dtex, preferably less than 1 ,500 dtex, more preferably less than 1 ,000 dtex, even more preferably less than 900 dtex, most preferably less than 860 dtex.This embodiment provides a targeted linear density range for the first warp yam set, wherein the lower threshold of >790 dtex, most preferably >830 dtex, ensures that the yarns visually mimic the character of traditional heavy fabrics (e.g., denim), provide surface volume, shadow depth, and distinct warp-face definition, deliver mass per length needed to create the impression of a dense woven structure, even at reduced densities, while the upper threshold of <860-2,000 dtex prevents excessive yam bulk that would increase fabric weight beyond the lightweight goal, impair wearability, drape, and wear comfort. This range maintains the visual illusion of mass while enabling structural efficiency and softness, central to the invention’s purpose.

[0100] In this embodiment, the warp yam density of the first set of warp yams is preferably between 830-860 dtex, which particularly ensures coarse appearance with controlled weight, wherein the first set of warp yams preferably have a warp yam density between 12-14 warps / cm and are preferably woven in a 3 / 1 twill weave, in particular to provide an optimal volume-to-mass ratio.

[0101] In an embodiment of any of the previously described aspects of the invention or their embodiments, the warp yams of the first set of warp yams have a yam count of at least 400 dtex, preferably at least 600 dtex, more preferably at least 700 dtex, even more preferably at least 750 dtex, most preferably at least 800 dtex, and / or less than 2,000 dtex, preferably less than 1 ,500 dtex, more preferably less than 1 ,200 dtex, even more preferably less than 1,000 dtex, most preferably less than 900 dtex. This provides a wider and more inclusive linear density range for the first warp yams, ensuring flexibility for different applications of the invention while still delivering the core benefits. The lower bound of 400-800 dtex allows the use of medium to coarse yams that can still simulate a heavy-look fabric but reduce fabric mass even further for lighter-weight or more drapey applications (e.g., shirts or light trousers). The upper bound of <900-2,000 dtex ensures the yams remain weavable and wearable, avoiding excessive thickness and weight. By providing this expanded range, this embodiment accommodates various product lines under the same inventive concept, from lightweight structured fabrics to robust outerwear-grade textiles.

[0102] Within the range of this embedment, in particular three different groups of configuration can be defined, namely a lighter-weight configuration, a midweight configuration and a

[0103] - Tl -higher weight configuration. For the lighter weight configuration, the first set of warp yarns may comprise a yam count of 650-750 dtex with a warp yarn density between 14-16 yarns / cm and a fabric weight between 220 and 280 g / m2, which might particularly be suitable for structured shirting, light trousers, or multi-season layering garments. For the midweight configuration, the first set of warp yarns may comprise a yarn count of 750-900 dtex with a warp density between 12 and 14 warps / cm and a fabric weight between 280 and 330 g / m2. For the higher weight configuration, the first set of warp yams may comprise a yam count of up to 1.200 dtex with a warp density between 8 and 10 warps / cm which is particularly useful for outerwear.

[0104] In an embodiment of any of the previously described aspects of the invention or their embodiments, the fabric has a fabric weight of less than 450 g / m2, preferably of less than 400 g / m2, more preferably of less than 370 g / m2, even more preferably of less than 350 g / m2, most preferably of less than 330 g / m2, and / or of at least 100 g / m2, preferably at least 170 g / m2, more preferably at least 220 g / m2, even more preferably at least 250 g / m2, most preferably at least 280 g / m2.

[0105] This embodiment defines a broad weight corridor for the fabric, ensuring that the invention remains applicable across a wide range of textile categories — while still fulfilling the core inventive goal of achieving a heavy-look with reduced actual weight. The maximum fabric weight of 450 g / m2accommodates even structural fabrics, such as outerwear, heavy trousers, or protective garments, while still leveraging the invention’s structural innovations to reduce binding point loss and slippage despite low warp densities. The minimum of 100-170 g / m2supports lightweight applications that visually mimic heavier cloth, such as shirts, loungewear, or drapey casualwear, while retaining mechanical cohesion. This flexibility expands the commercial and functional applicability of the invention, from heavy-duty textiles to lightweight everyday apparel.

[0106] Within the range of this embodiment, in particular four different ranges can be defined, namely a most preferred range, an expanded range, a lower range and an upper range. The most preferred range relates to fabrics with a fabric weight between 280-330 g / m2which is ideal for structured but wearable fabrics, such as denim-alternatives, overshirts, or jackets. The expanded range relates to fabrics with a fabric weight between 220-370 g / m2being particularly suitable for light pants, shirts with a structuredhand and layering pieces. The lower range relates to fabrics with a fabric weight between 170-220 g / m2being particularly suitable for lightweight weaves that still benefit from the invention’s slippage resistance and surface structure control. The upper range relates to fabrics with a fabric weight between 370 and 450 g / m2being particularly suitable for heavy-duty applications where reduced yam densities and smart dual-warp design save material without sacrificing function.

[0107] A fifth aspect of the invention relates to a method for weaving a fabric, in particular according to one of the first to the fourth aspects and / or its embodiments, comprising the step of weaving the first set of warp yarns, the second set of warp yarns and weft yams into the fabric, wherein the warp yams of the second set of warp yams have a lower yam count than the warp yams of the first set of warp yams, wherein the first set of warp yams has a warp yam density of less than 24 warps / cm. The method according to the fifth aspect of the invention may be performed in a way leading to a fabric as described with respect to one of the first to the fourth aspects and / or its embodiments.

[0108] A sixth aspect of the invention relates to a method, in particular according to the fifth aspect, for weaving a fabric, in particular according to one of the first to the fourth aspects and / or its embodiments, comprising the step of weaving the first set of warp yams, the second set of warp yams and weft yams into the fabric, wherein the warp yams of the second set of warp yams have a lower yam count than the warp yams of the first set of warp yams, wherein the first set of warp yams has a count-density, which can be calculated by multiplying the warp yam density of the first set of warp yams with the yam count of the warp yams of first set of warp yams, of less than 18.000 dtex / cm. The method according to the sixth aspect of the invention may be performed in a way leading to a fabric as described with respect to one of the first to the fourth aspects and / or its embodiments.

[0109] A seventh aspect of the invention relates to a method, in particular according to the fifth or sixth aspect, for weaving a fabric, in particular according to one of the first to the fourth aspects and / or its embodiments, comprising the step of weaving the first set of warp yams, the second set of warp yams and weft yams into the fabric, wherein the warp yams of the second set of warp yams have a lower yam count than the warp yams of the first set of warp yams, wherein the second set of warp yams has a warpyarn density of at least 8 warps / cm. The method according to the seventh aspect of the invention may be performed in a way leading to a fabric as described with respect to one of the first to the fourth aspects and / or its embodiments.

[0110] An eight aspect of the invention relates to a method, in particular according to one of the fifth to the seventh aspect, for weaving a fabric, in particular according to one of the first to the fourth aspects and / or its embodiments, comprising the step of weaving the first set of warp yarns, the second set of warp yams and weft yams into the fabric, wherein the warp yams of the second set of warp yams have a lower yam count than the warp yams of the first set of warp yams, wherein the second set of warp yams has a count-density, which can be calculated by multiplying the warp yam density of the second set of warp yams with the yam count of the warp yams of the second set of warp yams, of at least 700 dtex / cm. The method according to the eighth aspect of the invention may be performed in a way leading to a fabric as described with respect to one of the first to the fourth aspects and / or its embodiments.

[0111] In particular as a general concept of the present disclosure- which shall not be understood as limiting the scope of the invention - it could be said that a fabric comprising two distinct sets of warp yams is provided, namely a first set of warp yams, preferably comprising staple fibers, more preferably cotton fibers, which are relatively coarse and arranged at a defined low warp yam density, and a second set of warp yams, preferably comprising synthetic filaments, more preferably polyester filaments, which are finer, e.g. have a lower yam count, than the yams of the first set. The warp yams of the second set are preferably interwoven with the weft yams in a tighter weave pattern, preferably a 1 / 1 plain weave, while the warp yams of the first set are preferably interwoven in a coarser weave pattern, such as a twill weave. This difference in weave pattern particularly ensures that the second warp set contributes a greater number of binding points to the fabric, without significantly altering the external appearance or increasing the weight of the fabric. The second set of warp yams is preferably positioned between the yams of the first set and is in particular largely concealed by them, such that the coarse yams determine the visual and tactile impression of the fabric (i.e. , its “heavy” appearance), while the fine yams of the second set stabilize the internal structure and ensure resistance to slippage. By carefully adjusting the yam densities and count-densities of both warp yam sets, the invention provides a fabricconstruction that maintains dimensional stability and mechanical strength, even though it employs a lower total warp yam count and achieves a significantly reduced fabric weight.

[0112] As such, the fabrics according to the invention provide multiple technical advantages over conventional woven fabric constructions, such as lightweight with heavy look (the use of coarse staple yarns at reduced density allows for the visual appearance of a heavy fabric, while keeping the overall fabric mass low), slippage resistance at low densities (the second warp yam set significantly increases the number of interlacing (binding) points with the weft, ensuring structural integrity even at lower overall yam densities), dimensional stability (The invention provides sufficient internal cohesion to prevent slippage and deformation, particularly in garments subjected to mechanical stress), softness and drapability (the reduced total yam density contributes to a softer, more flexible fabric structure, ideal for applications requiring comfort, such as casual wear and loungewear), material efficiency (the design minimizes the need for high yam consumption, especially of coarse yams, offering cost and resource benefits during production) and design flexibility (by decoupling fabric weight from visual heaviness and structural integrity, the invention allows new fabric aesthetics and performance combinations not achievable with conventional weaving strategies).

[0113] In the following, further properties, features and advantages of the invention will become apparent by means of a description of preferred embodiments of the invention with reference to the accompanying exemplary drawings, showing in:

[0120] Fig. 9 a schematic view on Example 5 of a fabric according to the invention on the loom;

[0121] In the following, similar or same features will be designated with similar or same reference signs.

[0122] Fig 1 shows a fabric 1 with a first set of warp yams 3, which may be also referred to as “coarse yams” or “first warp yams”, and a second set of warp yams 5, which may also be referred to as “fine yams” or “second warp yams”. The weft yams are designated with reference sign 7. The fine yams 5 have a lower yam count than the coarse yams 3 which is schematically illustrated by using thinner lines for the fine yams 5 compared to the coarse yams 3.

[0123] Fig. 2 shows a fabric 1 comprising coarse warp yams 3 and weft yams 7. However, as indicated by the same thickness of all coarse yams 3, the fabric 1 in Fig. 2 does not comprise a second set of warp yams with a yam count being smaller than the yam count of the coarse warp yams thus being not according to the invention.

[0124] As can be seen by comparing Fig. 1 and Fig. 2, adding fine warp yams 5 into a fabric 1 with coarse warp yams 3 allows to significantly increase the number of binding points / cm2, while, as consequence of the low yam count of the fine warp yams, the fabric weight increases much less. As an alternative to increasing the binding points / cm2, the present invention also allows to decrease the fabric weight by replacing coarse warp yams with fine yams, to provide a certain number of binding points / cm2with a lower fabric weight.

[0125] In this context, as described with the first aspect of the invention, the additional connecting points provided by the fine warp yams can be used to reduce the warp yam density of the coarse warp yams to less than 24 warps / cm, thereby providing a fabricwith heavy look (provided by the coarse warp yarns), low weight (achieved by the replacing thick coarse warp yams by fine warp yams) and structural integrity (thanks to the same or an even increased number of connection points I cm2). As described with respect to the second aspect of the present disclosure, such heavy look in combination with a low weight can also be realized outside the range of less than 24 warps / cm, for example in fabrics with coarse warp yams with very high yam count, if, for example, the count-density is less than 18.000 dtex / cm. The same applies to the third aspect of the invention requiring a minimum value of 8 warps / cm to provide enough binding points by the fine warp yams and to the fourth aspect requiring a countdensity of at least 700 dtex / cm to provide sufficient binding points / cm even when the weft yam density as such is outside of the range of the third aspect of the invention. Further, to have a meaningful effect with respect to weight reduction it is beneficial to use a minimum quantity of fine warp yams compared to coarse yams, namely a ratio of coarse warp yam density to fine warp yam density of less than 2 / 1 , i.e. meaning that less than twice as many coarse warp yams are used as fine warp yams. In addition to that, decreasing the fabric weight by replacing coarse warp yams with fine warp yams can be used to increase the binding point density to 3.500 binding points I gram of the fabric or more which characterizes the fabric to achieve a high structural integrity with low weight. Last but not least, the replacement of coarse warp yams with fine warp yams can be used to provide fabrics with coarse yams having a yam count of at least 770 dtex (providing a heavy look) in combination with a light weight fabric having a weight of less than 375 gram / m2.

[0126] Comparative Example:

[0127] Fig. 2 shows a weave pattern of a comparative example of a fabric 1 not according to the invention described herein. As can be seen, the coarse warp yams 3 of example 1 are woven as 3 / 1 twill weave with weft yams 7 having a weave factor F = 0,25. In "off-loom, relaxed condition”, the coarse warp yams have a warp density of 26,88 warps / cm and the weft yams have a weft density of 18 wefts / cm. As a result, preferably in “off-loom relaced condition”, the fabric of the comparative example 1 has 120,96 binding points I cm2(0,25 x (26,88 x 18)). The coarse warp yams and the weft yams are cotton yams with 843 dtex. Respectively, the coarse warp yams have a count-density of 22.660 dtex / cm. The fabric, preferably in “off-loom relaxed state” has a weight of 440 gram / square meter leading to a binding point density of 2.749 binding points / gram.Example 1 :

[0128] Fig. 1 shows a weave pattern of Example 1 of a fabric 1 according to any aspect of the invention described herein. As can be seen, the coarse warp yams 3 of example 1 are woven as 3 / 1 twill weave while the fine warp yams 5 are woven in a 1 / 1 plain weave. As can be seen, the coarse warp yams 3 and the fine warp yams 5 are altered 1 by 1 , so that the ratio of coarse warp yam density to fine warp yam density is 1 :1. Thanks to the 1 / 1 plain weave (Weave Factor = 0,5) of the fine warp yams, the fine warp yams provide twice as many binding points with the weft yams as the 3 / 1 twill weave (weave factor F = 0,25) of the coarse warp yams. Preferably, in "off-loom, relaxed condition”, the coarse warp yams have a warp density of 13,44 warps / cm, the fine warp yams have a warp density of 13,44 warps / cm and the weft yams have a weft density of 15 wefts / cm. As a result, preferably in “off-loom relaced condition”, the fabric of example 1 has 151,2 binding points I cm2, wherein 50,4 binding points / cm2are provided by the coarse warp yams (0,25 x (13,44 x 15)) while 100,8 binding points / cm2are provided by the fine warp yams (0,5 x (13,44 x 15)). The coarse warp yams and the weft yams are cotton yams with 843 dtex. The fine warp yams are 78 dtex polyester filament yams. Respectively, the first set of warp yams has a count-density of 11.330 dtex / cm, while the second set of warp yams has a count-density of 10.048 dtex / cm. The fabric, preferably in “off-loom relaxed state” has a weight of 305 gram / square meter leading to a binding point density of 4.957 binding points / gram.

[0129] In summary, compared to the comparative example, example 1 has a lower weight (305 gram / square meter vs. 440 gram / square meter), a higher number of binding points / cm2(151,2 vs. 120,96) and thus also a higher binding point density (4.957 vs.

[0130] 2.749).

[0131] As a result example 1 looks heavy due to having thick (coarse) warp yams while having a lower weight (thanks to exchanging coarse warp yams by fine warp yams) than the comparative example and no slippage problem (thanks to the high number of connection points provided by the fine warp yams). In other words, example 1 is a lightweight fabric with low densities which looks heavy without having any slippage problem and is (thanks to the reduced warp density of coarse warp yams) softer and more drapey.Fig. 3 shows schematically a top view on the fabric according to Fig. 1 after finishing, such as shrinking. During finishing, the fabric usually shrinks in warp and weft direction which results in the fine warp yarns being covered (due to its lower yarn count) by the coarse warp yams which is beneficial in that it hides the fine warp yams inside the fabric so the fine yams do not interfere with the heavy look provided by the coarse yams.

[0132] Fig. 4 shows a schematic section view along line A-A in Fig. 3 schematically showing the extension of coarse warp yams 3 and fine warp yams 5 in warp direction after finishing. Fig. 5 shows how, in example 1 after finishing, a fine warp yam 5 is substantially hidden between two coarse warp yams 3.

[0133] Example 2:

[0134] Fig. 6 shows a weave pattern of Example 2 of a fabric 1 according to any aspect of the invention described herein. The only difference between Example 2 and Example 1 is that, in example 2, twice as many fine warp yams I cm are used compared to coarse warp yams, namely that each coarse warp yam is followed by two fine warp yam 5, wherein the fine warp yams are woven in a 1 / 1 plain weave, wherein over portions and under portions of adjacent fine warp yams 5 are offset to each other in weft direction.

[0135] Example 3

[0136] Fig. 7 shows a weave pattern of Example 3 of a fabric 1 according to any aspect of the invention described herein. The only difference between Example 3 and Example 2 is that, in example 3, the over portions and under portions of adjacent fine warp yams 5 being concealed in weft direction from both sides by a coarse warp yam are not offset from each other in warp direction, e.g. aligned with each other in warp direction.

[0137] Example 4

[0138] Fig. 8 shows a weave pattern of Example 4 of a fabric 1 according to any aspect of the invention described herein. The only difference between Example 4 and example 1 is that each pair of fine warp yams 5 is followed in weft direction on both sides by three coarse warp yams 3.Example 5

[0139] Fig. 9 shows a weave pattern of Example 5 of a fabric 1 according to any aspect of the invention described herein. The only difference between Example 5 and Example 1 is that the ratio of the density of the coarse warp yams to fine warp yams is not 1 / 1 but 4 / 3, wherein, in weft direction, single fine warp yams 5 are alternatively followed by single coarse yams and pairs of, i.e. two, coarse yams.

[0140] The features disclosed in the foregoing description, the figures, and the claims may be significant, both individually and in any combination, for the realization of the invention in the various embodiments.List of reference signs:
