AI Technical Summary
Existing fabric designs struggle to maintain structural integrity and anti-slip properties while reducing weight. Traditional methods result in dimensional instability of fabrics under mechanical stress and high production costs.
Two sets of warp systems are used. The first set consists of coarse short fibers, and the second set consists of fine synthetic filaments. By controlling the warp density ratio and the density of the bonding points, the fabric is made visually substantial and mechanically stable.
It achieves the heavy appearance of lightweight fabrics while maintaining high anti-slip properties and structural integrity, reducing fabric weight and improving mechanical durability.

Abstract
Description
[0001] The entire contents of this application are incorporated herein by reference to European Patent Application No. PCT / EP2025 / 060293, filed on April 14, 2025, in The Hague, entitled “Lightweight Fabric with Heavy Appearance Based on Two Warp Yarn Sets with Defined Warp Yarn Density Ratio, Binding Points / Gramand Minimum Coarse Yarn Count”. Technical Field
[0002] This invention relates to the textile field, particularly to textile fabrics, such as woven fabrics. The invention aims to construct a fabric that visually resembles traditional, heavy textiles while maintaining lightweight and high mechanical stability. More specifically, this invention relates to a double-warp system with specific parameters such as warp density ratio, bonding point density, fabric weight, and roving count and density design. These parameters ensure that the lightweight fabric has a substantial appearance while possessing improved structural integrity and anti-slip properties. Background Technology
[0003] In woven fabric design, the interplay between yarn count, yarn density, and weave pattern determines key physical and visual properties of the fabric, such as weight, flexibility, durability, and overall aesthetics. To make fabrics appear thicker and fuller, high-count yarns (i.e., rovings) are often used, resulting in heavyweight fabrics. These rovings provide a sense of volume and a substantial appearance, and due to their larger cross-sectional area and increased inter-yarn friction, they offer acceptable structural integrity even at lower yarn counts compared to fabrics made with finer yarns (i.e., lower-count yarns).
[0004] However, excessively reducing yarn density to decrease overall fabric weight can compromise the fabric's internal cohesion. Fewer warp and weft interlacing points and less friction between yarns lead to decreased resistance to yarn displacement, a phenomenon commonly known as slippage. This is particularly problematic in clothing applications, as fabrics are subjected to mechanical stresses during wear and need to maintain dimensional stability over time.
[0005] Traditional attempts to reduce fabric weight typically involve combining the use of finer yarns with reduced yarn density. While this approach can produce lightweight and breathable fabrics, the reduction in yarn knots often leads to a decrease in the structural integrity of the textile. Finer yarns usually require increased yarn density to prevent slippage; however, this increases fabric weight and production costs, thus limiting design flexibility. Furthermore, finer yarns do not necessarily make the fabric appear thicker or fuller.
[0006] While roving can help maintain structural stability at lower densities, there are physical limitations to this approach. When the interlacing frequency falls below a certain critical threshold, the increase in roving volume and friction is insufficient to ensure anti-slip properties. Therefore, traditional fabric design involves an inherent trade-off between weight, bulky appearance, and mechanical properties. Summary of the Invention
[0007] The purpose of this invention is to overcome the shortcomings of existing fabrics, and in particular to provide a fabric that combines the visual and volumetric characteristics of heavy fabrics while significantly reducing the overall weight, while ensuring sufficient structural integrity and resistance to yarn slippage, especially mechanical stress during wear.
[0008] More specifically, the present invention aims to overcome the limitations of conventional fabric structures that either rely on low-density rovings, leading to slippage at a critical density threshold, or rely on high-density fine yarns, resulting in increased weight and production complexity without achieving a substantial appearance.
[0009] The present invention aims to design lightweight fabrics with a substantial appearance while maintaining a high number of interlacing points (joints) and ensuring the dimensional stability of the fabric over time, especially in applications requiring drape, comfort and mechanical durability, such as clothing.
[0010] The objective of this invention is achieved by the independent claims. The dependent claims show preferred embodiments. Attached Figure Description

[0020] In this designation, 1 represents the fabric, 3 represents the first group of warp yarns (coarse warp yarns), 5 represents the second group of warp yarns (fine warp yarns), and 7 represents the weft yarns. Detailed Implementation
[0021] A first aspect of the invention relates to a fabric 1 comprising a first set of warp yarns 3, particularly composed of short fibers, and a second set of warp yarns 5, particularly composed of synthetic filaments, wherein the yarn count of the second set of warp yarns 5 is lower than that of the first set of warp yarns 3, and wherein the ratio of the warp density of the first set of warp yarns 3 to the warp density of the second set of warp yarns 5 is less than 2 / 1. Alternatively, it can be stated that the insertion frequency of the first set of warp yarns 3 does not exceed twice that of the second set of warp yarns 5, particularly ensuring that the structural function of the second set of warp yarns 5 is maintained. This embodiment establishes a maximum permissible ratio between the warp density of the first set of warp yarns (coarse short fiber yarn) and the warp density of the second set of warp yarns (fine long filament yarn). The ratio of the warp density of the first set of warp yarns 3 to the warp density of the second set of warp yarns 5 being less than 2 / 1 ensures that the second set of warp yarns 5 system is sufficiently dense to provide structural stability, increase the number of bonding points, and compensate for the reduced interlacing frequency of the first set of warp yarns 3 system (e.g., in a 3 / 1 twill or similar pattern). This ratio helps achieve low overall fabric weight, a substantial appearance (from the coarse warp yarns), and high anti-slip properties (from the fine warp yarns). By limiting the imbalance in warp density, a stable warp system is ensured to be maintained within the structure. Keeping the ratio below 2 prevents excessive dominance of the coarse warp yarns, which could otherwise lead to slippage, open structures, or dimensional instability.
[0022] The warp density ratio can be calculated as follows:
[0023] Warp density of the first group of warp yarns (3) / warp density of the second group of warp yarns
[0024] If the warp density of the second group of warp yarns 5 is the same as or higher than that of the first group of warp yarns 3, then the ratio is ≤1, which is more preferable.
[0025] In one embodiment, the warp density ratio is between 1.0 and 1.5, specifically to ensure that the coarse warp yarns visually dominate (low density, large diameter), while the fine filaments stabilize the structure.
[0026] According to one embodiment of the first aspect or its embodiments, the ratio of the warp density of the first group of warp yarns 3 to the warp density of the second group of warp yarns 5 is 7 / 4 or lower, preferably 5 / 3 or lower, more preferably 3 / 2 or lower, most preferably 1 / 1 or lower, and / or 1 / 5 or higher, preferably 1 / 4 or higher, more preferably 1 / 3 or higher, and most preferably 1 / 2 or higher. Alternatively, it can be stated that the insertion frequency of the first group of warp yarns 3 does not exceed 7 / 4 of that of the second group of warp yarns 5, and the density of the first group of warp yarns 3 is at least one-fifth of the density of the second group of weft yarns 5, preferably close to or equal to one-to-one. This embodiment defines a specific design window for the relative densities of the first group of warp yarns (coarse) and the second group of warp yarns (fine). The defined ratio ensures that the coarse warp system dominates in appearance, while the fine warp system maintains an effective presence in structure. This range covers both ends of the possible configurations, where a ratio ≤ 7 / 4 (1.75) limits the overemphasis on the first group of warp yarns 3, while a ratio ≥ 1 / 5 (0.2) prevents the second group of warp yarns 5 from becoming dominant or overwhelmingly superior in visual and mechanical properties. The core inventive structure benefits from a relative balance or slight imbalance between the warp systems, typically ranging from 1:2 to 3:2.
[0027] In this embodiment, the first and second warp yarns can have equal warp density (ratio 1:1), a fine warp-dominated structure (ratio <1:1), or a coarse warp-dominated structure (2 / 1 > ratio >1:1). These ratios not only reduce the total yarn count while maintaining the fabric weight reduction target, but also improve the cohesion of the structure due to the increased interlacing of the second warp yarn system 5, and retain a substantial appearance because the fine yarns remain invisible under the coarse surface. When the second warp yarn system 5 is woven in a plain weave, a ratio below 1 is particularly preferred, significantly increasing the bonding density.
[0028] In a first aspect of the invention or an embodiment thereof, the ratio of the warp density of the first group of warp yarns 3 to the warp density of the second group of warp yarns 5 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, and most preferably 1 / 1.
[0029] This embodiment introduces a set of discrete warp density ratios, each reflecting a balanced or functionally optimized relationship between the coarse (first) warp and the fine (second) warp. These ratios provide practical design templates designed to enhance the balanced structure with the second set of warp yarns 5 while achieving visual advantage and aesthetic control with the first set of warp yarns 3. This embodiment reflects the inventors' observation that the correct proportions of each warp system are more important than absolute proportions. These ratios provide easily implementable construction rules for fabric designers and weavers working within the inventive parameters. The most preferred embodiment uses a 1 / 1 ratio, which is ideal when both sets of warp yarns are set at the same density (e.g., 12 / 12 cm), as it provides a balanced structure and interlacing mesh.
[0030] The second aspect of the invention, which can be combined with the first aspect and its embodiments, and vice versa, relates to a fabric 1 comprising a first set of warp yarns 3, particularly composed of short fibers, and a second set of warp yarns 5, particularly composed of synthetic filaments, wherein the yarn density of the second set of warp yarns 5 is less than that of the first set of warp yarns 3, and wherein the bond point density of the fabric 1 is at least 3500 bond points per gram. This embodiment specifically introduces the number of bond points per gram of fabric, which particularly reflects the fabric's ability to efficiently translate its mass into structural stability. When the bond point density is ≥3500 bond points / gram, the fabric is not only lightweight and soft, but also exhibits high interweaving cohesion, demonstrating excellent anti-slip properties, dimensional stability, and durability. This characteristic is particularly beneficial for lightweight fabrics with low warp and weft densities, which often create structural weaknesses. A high bond point density per unit mass indicates that these structural weaknesses are eliminated through intelligent construction rather than through a crude quantity of material.
[0031] The density per gram of binding points can be calculated as follows:
[0032] Bonding point / gram = (bonding point / cm) 2 ×10,000) / (fabric weight (g / m) 2 ))
[0033] The parameter "joint points / cm²" specifically refers to the sum of the joint points contributed by the two warp systems, as disclosed herein. The parameter "fabric weight" specifically refers to the weight of the fabric per square meter in grams. Preferably, joint points / cm² 2 The point of contact / gram is measured outside the loom when the fabric is in a relaxed state, as specifically described above.
[0034] In the context of this invention, a junction point (also called an interlacing point) is specifically defined as a structural interlacing location in a fabric where a warp yarn intersects a weft yarn, forming a mechanical intersection comprising an upper portion and a lower portion. In particular, unlike counting every warp and weft yarn intersection as a junction point, this invention counts a complete interlacing cycle, including an upper portion and a lower portion, as one junction point. Specifically, the number of junction points per unit area (junction points / cm²) is also considered. 2 The result is calculated using the following formula:
[0035] Joint point / cm 2 = (warp density × weft density) / F,
[0036] Here, "F" stands for "fabric factor." Specifically, the fabric factor is defined as the number of weft yarns a warp yarn must pass through to complete a full weave cycle (including an upper section and a lower section, or vice versa). This fabric factor specifically reflects the repeatability of the fabric structure and is used to calculate the effective number of weft yarns per square centimeter. For example, in a plain weave fabric, each warp yarn alternates with each weft yarn, so a warp yarn must pass through two weft yarns to complete a full weave cycle, including an upper section and a lower section; therefore, the weave factor F is 2. In another example of a 3 / 1 weave, a warp yarn must pass through three weft yarns to form an upper section and through one weft yarn to form a lower section, or vice versa. Therefore, a total of four weft yarns are needed to complete a full weave cycle, including an upper section and a lower section; therefore, the weave factor F is 4. In other words, for a 1 / 1 weave fabric made of one set of warp yarns and one set of weft yarns, the number of weft yarns per square centimeter can be calculated as: warp density × weft density × 0.5 (1 / 1 weave weave factor F). For a 3 / 1 woven fabric made of one set of warp yarns and one set of weft yarns, the number of join points is [number] cm. 2 The following calculation can be made: warp density × weft density × 0.25 (3 / 1 weave factor). In the fabric of this invention, for example, the first group of warp yarns 3 interweaves with the weft yarns in a 3 / 1 weave, and the second group of warp yarns 5 interweaves with the weft yarns in a 1 / 1 weave, with the joining points per cm. 2 This can be calculated as: warp density of the first warp group × weft density × 0.25 (3 / 1 weave factor F) + warp density of the second warp group × weft density × 0.5 (1 / 1 weave factor F). In other words, in embodiments with multiple warp groups and one weft group, the bonding point per square centimeter is preferably calculated by adding the bonding point per square centimeter of each warp group to the bonding point per square centimeter of the corresponding weft group.
[0037] In a preferred embodiment, the first warp system (roving) is typically woven in a twill or similar pattern with a low interlacing frequency, contributing fewer bonding points. The second warp system (fine synthetic filaments) is typically woven in a plain weave pattern, significantly increasing the total number of bonding points and thus compensating for the open structure of the roving. The calculated total number of bonding points per square centimeter and / or per gram of fabric is a quantitative indicator of fabric structural stability and anti-slip properties, and can be used as a design control parameter.
[0038] In an embodiment of the second aspect of the invention, the bonding point density of the fabric is at least 3,900 bonding points per gram, preferably at least 4,300 bonding points per gram, more preferably at least 4,600 bonding points per gram, even more preferably at least 4,800 bonding points per gram, most preferably at least 4,900 bonding points per gram, and / or less than 10,000 bonding points per gram, preferably less than 9,000 bonding points per gram, more preferably less than 8,000 bonding points per gram, even more preferably less than 7,000 bonding points per gram, and most preferably less than 6,000 bonding points per gram.
[0039] This embodiment defines the optimized structural efficiency window of the invention—the number of interlacing points per gram of fabric—with a minimum and a maximum threshold. At least 3900-4900 interlacing points per gram ensures extremely high interlacing efficiency per unit mass, excellent anti-slip properties, and strong dimensional stability, with very low material usage. This design performs exceptionally well in lightweight clothing, upholstered furniture, or fabrics that are both durable and flexible. The maximum value of 6000-10000 interlacing points per gram avoids an overly tight structure, which increases fabric stiffness, reduces drape and comfort, and can negatively impact aesthetic goals (e.g., an overly flat or stiff surface). This embodiment particularly provides a good balance between weight reduction, structural performance, and tactile quality.
[0040] In this embodiment, the bonding density per square centimeter is preferably between 140 and 160, for example, the first set of warp yarns can be used in a 3 / 1 twill weave and in a 1 / 1 plain weave, and the warp density of both sets of warp yarns is 12 to 14 yarns / cm, preferably combined with a fabric weight of 290 to 330 g / m², and particularly with a bonding density of 4,500 to 5,000 bonding points per gram.
[0041] In another embodiment of the second aspect of the invention, the fabric has at least 80 webbing points per square centimeter, preferably at least 100 webbing points per square centimeter, more preferably at least 115 webbing points per square centimeter, even more preferably at least 130 webbing points per square centimeter, most preferably at least 145 webbing points per square centimeter, and / or less than 300 webbing points per square centimeter, preferably less than 250 webbing points per square centimeter, more preferably less than 200 webbing points per square centimeter, even more preferably less than 180 webbing points per square centimeter, and most preferably less than 160 webbing points per square centimeter. The term "webbing point density" can also be referred to as the total interlacing frequency per square centimeter, structural interlacing density, or webbing point area coverage.
[0042] This embodiment specifically defines the absolute bond density per surface area, i.e., how many warp and weft interlacing points are contained per square centimeter of fabric. At least 80-145 bond points per square centimeter ensures excellent dimensional stability, high anti-slip properties, and good tear and tensile strength, even with reduced fabric weight. An upper limit of 160-300 bond points / square centimeter avoids excessive weaving, which increases stiffness, reduces drape and softness, and increases material consumption without further benefits. The range between the lower and upper limits has been found to represent a beneficial balance between openness and cohesion, allowing the fabric to be both lightweight and visually dense, with high mechanical strength.
[0043] In this embodiment, the ideal warp density is between 115 and 145 warp points per square centimeter. This can be achieved, for example, by using a first set of warp yarns in a 3 / 1 twill weave with a warp density of 12 to 14 yarns per centimeter; and a second set of warp yarns in a 1 / 1 plain weave with a warp density of 12 to 14 yarns per centimeter, while the weft density is 14 to 16 weft yarns per centimeter. This configuration particularly provides high-performance, lightweight woven fabrics for clothing and heavy-duty textiles with reinforced internal structures.
[0044] In any of the foregoing aspects or embodiments thereof, the yarn count of the first set of warp yarns is 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 2000 dtex, preferably less than 1500 dtex, more preferably less than 1200 dtex, even more preferably less than 1000 dtex, and most preferably less than 900 dtex. This provides a wider and more inclusive range of linear densities for the first set of warp yarns, ensuring that the invention is applicable to different applications while still providing the core benefits. The lower limit of 400-800 dtex allows the use of medium to coarse yarns, which can both simulate the effect of a heavy-looking fabric and further reduce the weight of the fabric, suitable for lightweight or better-draping applications. The upper limit of <900-2000 dtex ensures that the yarn is both knittable and wearable, avoiding fabrics that are too thick and / or too heavy. By offering this extended range, this embodiment adapts to a variety of product lines under the same innovative concept, from lightweight structured fabrics to robust outerwear-grade textiles.
[0045] Within this embedding scope, three distinct configurations can be defined: lightweight, medium, and heavyweight. For the lightweight configuration, the first warp group might consist of yarns with a count of 650-750 dtex, a warp density of 14-16 ends / cm, and a fabric weight of 220-280 g / m². This could be particularly suitable for structured shirts, lightweight trousers, or multi-season layered garments. For the medium-weight configuration, the first warp group might consist of yarns with a count of 750-900 dtex, a warp density of 12-14 ends / cm, and a fabric weight of 280-330 g / m². For the heavyweight configuration, the first warp group might consist of yarns with a count up to 1200 dtex and a warp density of 8-10 ends / cm. This is particularly useful for outerwear.
[0046] In any of the foregoing aspects or embodiments thereof, the fabric has a fabric weight of less than 450 g / m², preferably less than 400 g / m², more preferably less than 370 g / m², even more preferably less than 350 g / m², most preferably less than 330 g / m², and / or 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.
[0047] This embodiment defines a broad fabric weight corridor, ensuring the invention can be applied to a wide range of textile categories—while still achieving the core innovative goal of achieving a substantial appearance while reducing actual weight. The maximum fabric weight is 450 g / m², accommodating even structural fabrics such as coats, heavy trousers, or protective clothing, while still utilizing the invention's structural innovations to reduce joint loss and slippage, despite low warp density. Minimum weights of 100-170 g / m² support lightweight applications that visually mimic heavier fabrics, such as shirts, casual wear, or flowing loungewear, while maintaining mechanical cohesion. This flexibility expands the invention's commercial and functional applicability, from heavy textiles to lightweight everyday clothing.
[0048] Within the scope of this embodiment, four distinct ranges can be defined: the optimal range, the extended range, the lower range, and the higher range. The optimal range pertains to fabrics with a weight between 280 and 330 g / m², ideal for structured yet wearable fabrics such as denim alternatives, jackets, or overcoats. The extended range pertains to fabrics with a weight between 220 and 370 g / m², particularly suitable for lightweight trousers, shirts with a structured feel, and layered garments. The lower range pertains to fabrics with a weight between 170 and 220 g / m², particularly suitable for lightweight knits that still benefit from the anti-slip properties and surface texture control of this invention. The higher range pertains to fabrics with a weight between 370 and 450 g / m², particularly suitable for heavy-duty applications where reduced yarn density and intelligent double-warp design save material without sacrificing functionality.
[0049] A third aspect of the invention, which can be used in conjunction with the first and / or second aspects and their embodiments, and vice versa, relates to a fabric comprising a first set of warp yarns, particularly composed of short fibers, and a second set of warp yarns, particularly composed of synthetic filaments, wherein the yarn count of the second set of warp yarns is lower than that of the first set of warp yarns, the fabric weighing less than 375 g / m², and the yarn count of the first set of warp yarns being at least 770 dtex. Preferably, the fabric is a woven fabric.
[0050] This ensures that the fabric visually mimics heavy textiles by using thicker yarns (≥770 dtex) in the first warp group, which provides volume, space, and surface definition while reducing physical weight by keeping the total fabric mass below 375 g / m². These limitations collectively define a new category of fabric: lightweight yet appearing substantial in both look and performance. The roving count in the first warp group 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 clothing, upholstery, or multi-season apparel.
[0051] In this regard, the fabric weight is preferably between 280 and 340 grams per square meter, which provides sufficient bonding points while maintaining a low weight, while the yarn count of the coarse warp is preferably between 770 and 900 dtex to provide visual texture and volume or heavier textiles.
[0052] In any third aspect or embodiment thereof, the weight of the fabric is preferably less than 350 g / m², more preferably less than 330 g / m², and / or at least 100 g / m², more preferably at least 170 g / m², further preferably at least 220 g / m², even more preferably at least 250 g / m², and most preferably at least 280 g / m². This characteristic provides a preferred operating range for the area weight of the fabric, reinforcing the invention's dual objective of achieving the visual and tactile properties of heavy-duty woven fabrics, and providing a practical sense of lightness, softness, and drape by limiting the weight per unit area. The defined range specifically avoids fabrics that are too stiff or heavy to affect comfort (≥350 g / m²), excludes fabrics that are too light and structurally weak (≤100-170 g / m²), and facilitates designs that look and behave like heavier fabrics, but are still suitable for comfortable clothing, layering, or lightweight technical applications.
[0053] Fabric weight can be expressed in grams per square meter (g / m²) according to ISO 3801 or ASTM D3776. 2 Measurements are taken in units of 1000 (units), with fabric samples preferably conditioned according to ISO 139 standards under standard temperature and humidity conditions, ensuring the fabric is in a relaxed state, i.e., without tension. Furthermore, the fabric can be unprocessed or processed using standard textile finishing parameters according to the product definition, but unprocessed is preferred.
[0054] In this embodiment, the most preferred range involves a fabric with a weight between 280 g / m² and 330 g / m², a range particularly well-matched to the typical weight of medium-weight twill and workwear, ensuring high bonding efficiency and maintaining the fabric's lightness, breathability, and flowiness while providing structural strength. In alternative embodiments, the fabric weight is between 170-220 g / m², which can be used for soft, sleepwear-like woven garments, shirts with a high visual texture but a soft touch, and lightweight outer layers designed to mimic canvas or denim. In yet another alternative embodiment, the fabric weight is between 330-350 g / m², which can be preferentially used for structured fabrics (e.g., jackets, trousers and layered garments, structured casual wear, or soft accessories).
[0055] In the third aspect of the invention or in any embodiment thereof, the warp count of the first group of warp yarns is at least 790 dtex, preferably at least 810 dtex, most preferably at least 830 dtex, and / or less than 2000 dtex, preferably less than 1500 dtex, more preferably less than 1000 dtex, even more preferably less than 900 dtex, and most preferably less than 860 dtex.
[0056] This embodiment provides a target linear density range for the first set of warp yarns, with a lower limit ≥790 dtex and an optimal value ≥830 dtex. This ensures the yarns visually mimic the characteristics of traditional heavy-duty fabrics (e.g., denim), providing surface volume, shadow depth, and a clear reverse texture. Even at reduced density, it creates the visual effect of a densely woven structure through mass per unit length. The upper limit, ≤860-2000 dtex, prevents excessive yarn volume from increasing fabric weight beyond the lightweight target, compromising wearability, drape, and comfort. This range maintains the visual illusion of mass while achieving structural efficiency and softness, which is the core objective of this invention.
[0057] In this embodiment, the warp density of the first set of warp yarns is preferably between 830 and 860 dtex, which particularly ensures a rough appearance and controlled weight. The warp density of the first set of warp yarns is preferably between 12 and 14 yarns / cm, and a 3 / 1 twill weave is preferably used, especially to provide the best volume to weight ratio.
[0058] In any of the foregoing aspects or embodiments thereof, the warp count of the second set of warp yarns is 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 the yarn count is 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.
[0059] This embodiment introduces a well-defined yarn count range for the second set of warp yarns, namely a refined, stable warp system that complements the coarser, lower-density first set of warp yarns. This range ensures that the second set of warp yarns, composed of yarns such as synthetic filaments, is significantly finer than the coarse, short fibers of the first set of warp yarns. As described in the inventive concept, this keeps the fabric lightweight and minimizes invasiveness, contributing to internal structural integrity without affecting the fabric's surface appearance, weight, or hand feel, and provides sufficient bonding capacity per unit area when used within the yarn density and / or count density range specified herein for the second set of warp yarns. The result is a lightweight fabric with a substantial appearance, structurally stabilized by a nearly invisible network of fine warp yarns.
[0060] In particular, in this embodiment, the second set of warp yarns is preferably made of continuous synthetic filaments of polyester or nylon with a yarn count between 60 and 100 dtex, more preferably between 70 and 90 dtex, which particularly helps to improve tensile strength and reduce elongation, thereby resisting deformation and enhancing the stability of the knot.
[0061] In any of the foregoing aspects of the invention or an embodiment thereof, the yarn count of the first set of warp yarns is at least 200% of the yarn count of the second set of warp yarns, preferably at least 400%, more preferably at least 600%, even more preferably at least 800%, most preferably at least 1000%, greater than the yarn count of the second set of warp yarns and / or less than 3000%, preferably less than 2500%, more preferably less than 2000%, even more preferably less than 1500%, most preferably less than 1200%. This embodiment introduces a proportional relationship between the coarser first set of warp yarns and the finer second set of warp yarns, ensuring that, due to their significantly higher linear density (coarser yarns), the first set of warp yarns dominates the surface appearance and visual structure of the fabric, while the second set of warp yarns remains hidden, contributing bonding points as structural stabilizers without altering the fabric's appearance or feel. By setting the yarn count of the first set at least 200%, preferably at least 400% or 600% higher than that of the second set, the present invention ensures a clear functional and visual separation between the two systems. Limiting the ratio to less than 3000%, preferably 1200%, ensures that the second group still provides sufficient material mass per centimeter to produce a meaningful structural effect.
[0062] The yarn count of the first group of warp yarns is greater than that of the second group of warp yarns, or it can be expressed as the yarn count of the first group of warp yarns being between x and y, for example, 2× to 30×, and the yarn count of the second group of warp yarns being preferably between 6× and 12×.
[0063] In this embodiment, the yarn count of the coarse warp is preferably between 800-900 dtex (e.g., cotton staple fiber), while the yarn count of the second set of warp yarns is between 70-90 dtex (e.g., polyester filament). In particular, because the yarn count of the coarse warp is 800-900% higher than that of the fine warp, this not only ensures that the coarse warp defines the visual and tactile quality of the fabric, but also allows the fine warp to enhance the structural cohesion of the fabric, maximizing the fabric's aesthetic and weight performance ratio.
[0064] In any of the foregoing aspects of the invention or in one embodiment of an embodiment thereof, the warp yarns of the first set of warp yarns are preferably composed of short fibers, preferably cotton fibers.
[0065] This implementation specifically defines the coarse warp yarns that form the visually dominant and structurally coarser layer of the fabric as being made of short fibers, with cotton being the preferred material. The use of short fibers, especially cotton, offers several advantages in the context of this invention, such as visual and tactile volume (short fiber yarns tend to have more volume and texture than filament yarns, enhancing the fabric's "thickness"), surface coverage (their fuzzy and fibrous characteristics help conceal the fine synthetic yarns in the second set of warp yarns, maintaining the desired appearance), comfort (cotton provides excellent skin feel, moisture absorption, and breathability, making it suitable for applications involving direct skin contact), and process compatibility (cotton yarns are ideal for twill weaves and are commonly used in denim, workwear, and casual wear).
[0066] By optionally limiting the composition to "composed of" short cotton fibers, this embodiment allows the first set of warp yarns to function as the aesthetic and mechanical basis of the fabric, consistent with the concept of the invention.
[0067] The term “short fiber” specifically refers to fibers of finite length (as opposed to continuous filaments), which can be natural, regenerated, or synthetic.
[0068] The roving can consist of ring-spun yarns, particularly ring-spun cotton yarn (preferred for its softness and strength), or open- or compact-spun yarns (depending on the desired feel and surface characteristics). Alternatively, the roving can be composed of blended yarns, such as a blend of cotton and 10-20% polyester, which can be used to improve dimensional stability, reduce shrinkage, or enhance abrasion resistance while retaining the visual and tactile properties of cotton. Alternatively, the roving can be woven together with the weft yarns in a twill weave (e.g., 3 / 1, 2 / 2), resulting in longer surface floats so that the roving defines the visual texture of the fabric, while a second set of warp yarns provides structural reinforcement.
[0069] In any of the foregoing aspects of the invention or in one embodiment of an embodiment thereof, the second set of warp yarns consists of filaments, preferably of synthetic materials, particularly polyester or nylon, with polyester being most preferred. The use of synthetic continuous filaments, particularly polyester, directly supports the technical objectives of the invention and provides several advantages. They possess high linear strength at very low yarn counts, allowing the use of yarns with strong structural contributions, increasing the density of bonding points without increasing volume. Their low elongation ensures that these yarns anchor the fabric and prevent slippage, especially under stress (movement, washing). Their smooth filament surface makes them inconspicuous on the fabric surface, hidden beneath the coarser first set of warp yarns, thus preserving the desired "weightiness." Their durability, moisture resistance, and shape retention make synthetic filaments particularly suitable as reinforcing materials in multi-component fabric structures.
[0070] The phrase "contains filaments" specifically allows for partial filament structures, such as core-sheath or wrap-around yarns. The phrase "composed of filaments" specifically restricts the second set of warp yarns to 100% continuous monofilaments or multifilaments. The phrase "contains synthetic materials" specifically includes a wide range of polymers, such as polyester (preferred), nylon (polyamide), polypropylene, polyethylene, or elastomer filaments. Polyester is the most favored choice due to its high modulus, heat and chemical resistance, wide availability in denier ranges (e.g., 70-90 denier), and good compatibility with cotton warp systems.
[0071] In this embodiment, the fine warp yarn is preferably composed of multiple filaments, particularly multifilament polyester (e.g., 34 filaments, low denier yarn per filament) to achieve high flexibility and minimal surface visibility. Alternatively, low denier monofilaments can be used for stiffer applications. Furthermore, the yarn count of the fine warp yarn is preferably between 60 and 100 dtex, more preferably between 70 and 90 dtex. Additionally, the fine warp yarn is preferably woven in a 1 / 1 plain weave, particularly to maximize bonding points. Furthermore, the fine warp yarn is preferably interwoven between the coarse warp yarns, particularly to form an internally stable mesh. Furthermore, the tensile strength of the fine warp yarn is at least 2.5 cN / dtex, the elongation at break is less than 20%, and the moisture recovery is less than 1%. For high-performance fabrics (e.g., workwear or technical textiles), nylon filaments may be preferred due to their enhanced abrasion resistance. For products focused on sustainability, recycled polyester (rPET) filaments can be used.
[0072] In one embodiment of any of the foregoing aspects of the invention or of any of its embodiments, the first set of warp yarns and the weft yarns of the fabric are interwoven into a pattern different from a 1 / 1 plain weave, wherein the pattern is preferably a twill weave, satin weave, or blue weave, more preferably a twill weave, and most preferably a 3 / 1 twill weave. Alternatively, it can be said that the coarse warp yarns are woven in a pattern that reduces the frequency of interweaving with the weft yarns compared to the finer yarns, such as a twill or satin weave, which in particular enhances surface visibility and volume.
[0073] This embodiment specifically specifies coarse warp yarns, which particularly contribute to the visual and tactile properties of the fabric. Instead of a plain weave, they are woven in a pattern with fewer interlacing points, such as twill, satin, or basket weave. Choosing a non-plain weave, especially a twill weave, has multiple functional effects: its lower interlacing frequency results in longer floats on the surface of the coarse warp yarns, allowing them to dominate the fabric's appearance and provide the desired "weight." Patterns like 3 / 1 twill (one interlacing for every four weft yarns) reduce the number of interlacing points contributed by the first set of warp yarns—this is intentional—and the second set of warp yarns structurally compensates for this. While twill weaves have a structural appearance, their slanted surface effect enhances the aesthetics of the textile, typically in fabrics like denim, khaki, or workwear.
[0074] In this embodiment, the coarse warp yarn preferably rises above one weft yarn and below three weft yarns, then below one weft yarn. Alternatively, the coarse warp yarn can be woven in a 2 / 2 twill (balanced appearance and drape), a four-end satin (higher gloss and smoother hand feel), or a basket weave (thick, textured surface, but limited structural control).
[0075] In any of the foregoing aspects or embodiments thereof, the second set of warp yarns interweaves with the weft yarns of the fabric in a 1 / 1 plain weave and / or a pattern different from the pattern in which the first set of warp yarns interweaves with the weft yarns of the fabric. Preferably, the number of interlacing points under this pattern is at least 50% greater than the pattern in which the first set of warp yarns interweaves with the plant-based weft yarns, and most preferably at least 100% greater. Alternatively, it can be said that the interlacing frequency of the second set of warp yarns with the weft yarns is higher than the interlacing frequency of the first set of warp yarns with the weft yarns. As a further alternative, it can be said that the two sets of warp yarns are woven in different patterns, wherein their interlacing point contributions are asymmetrical, i.e., the second set of warp yarns primarily ensures the mechanical strength of the structure, while the first set of warp yarns provides aesthetic and tactile properties.
[0076] This embodiment specifically defines a tighter interlacing pattern between the fine warp and weft yarns than the interlacing pattern of the first (coarse) warp yarns, preferably a 1 / 1 plain weave, which maximizes the frequency of the interlacing points. This allows the fine warp yarns to act as an internal stabilizing mesh, compensating for the lower interlacing frequency of the first set of warp yarns (e.g., twill weave). The fine warp yarns generate at least 50% more interlacing points per square centimeter than the first set of warp yarns, ideally reaching 100% or more, thereby significantly increasing the overall interlacing point density of the fabric. This setup prevents warp / weft slippage and improves dimensional stability, even with low total warp density and reduced fabric weight.
[0077] The expression "a pattern with more interlacing points" specifically means that, per unit area, the interlacing structure formed by the second set of warp and weft yarns is denser than that of the first set of warp yarns. The second set of warp yarns can be woven in a 1 / 1 plain weave (one up, one down) or any pattern that produces a higher interlacing frequency than the thicker warp yarns (e.g., 2 / 2 twill versus 3 / 1 twill).
[0078] In any of the foregoing aspects or embodiments thereof, the weft density is at least 6 yarns / cm, preferably at least 8 yarns / cm, more preferably at least 10 yarns / cm, even more preferably at least 12 yarns / cm, most preferably at least 14 yarns / cm, and / or less than 50 yarns / cm, preferably less than 30 yarns / cm, more preferably less than 20 yarns / cm, even more preferably less than 18 yarns / cm, most preferably less than 16 yarns / cm.
[0079] This embodiment describes the density of the weft system, a structural element that interacts with the two sets of warp yarns to create bonding points and control the mechanical integrity, hand feel, and dimensional properties of the fabric. The minimum weft density is 6 to 14 yarns / cm, ensuring sufficient interlacing opportunities to support both sets of warp yarns, which is especially important when the first set of warp yarns has a low density and the second set must stabilize the fabric. The upper limit is 16 yarns / cm, particularly to prevent over-tightening of the fabric, maintaining softness and drape, lightweight construction, breathability, and the desired low-weight feel of the product. Therefore, this range of weft densities aims to maximize bonding point efficiency while minimizing weight. The most preferred weft density is 12 to 16 yarns / cm, especially in garments requiring a balance between structure and drape. For soft fabrics, a weft density of 10 to 12 yarns / cm may be preferred, while 14 to 16 yarns / cm provides greater structural integrity and resilience.
[0080] In any of the foregoing aspects or embodiments thereof, the weft yarn has a count density that can be calculated by multiplying the weft yarn density by the yarn count of the weft yarn, and is 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 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.
[0081] This embodiment describes a weft yarn count density, specifically a structural metric reflecting the quality of weft yarn material per unit width of fabric. Similar to the warp yarn count density disclosed herein, weft yarn count density can be used to balance fabric weight, structural stability, and bonding performance. The minimum count density (≥8,000 dtex / cm) specifically ensures sufficient weft yarn material to make adequate contact with both sets of warp yarns, creating sufficient bonding points and providing lateral reinforcement for mechanical integrity. The maximum count density (≤25,000 dtex / cm, preferably ≤13,500 dtex / cm) specifically ensures that the fabric remains lightweight and flexible, without becoming overly stiff or heavy due to excessive weft yarn insertion. This embodiment allows designers to control the influence of weft yarns on fabric structure without specifying absolute yarn size or pick-up.
[0082] In this embodiment, the weft yarn count density is preferably between 12,000 and 13,500 dtex / cm, which is particularly advantageous for generating a high bonding density together with the second set of warp yarns, maintaining the fabric's softness, drape, and lightweight. For example, such a count density can be achieved by using weft yarns with a count between 800 and 1000 dtex and a weft yarn density of 12-14 yarns / cm. Fabrics within this range feel particularly light yet strong, exhibiting minimal slippage, and are suitable for apparel, home textiles, and durable fashion fabrics.
[0083] In any of the foregoing aspects or embodiments thereof, the weft yarn comprises, preferably, yarn having a yarn 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.
[0084] The lower limit (≥200 dtex) specifically ensures that the weft yarns provide sufficient mass and surface area to effectively bond with the warp yarns, particularly the coarser first set of warp yarns, which float on multiple picks in low-bonding patterns such as twill. The upper limit (≤900~2,000 dtex) prevents the weft yarns from becoming too heavy or stiff, which would impair drape and feel, prevent the fabric weight from exceeding the objectives of this invention, and interfere with the "lightweight-heavy appearance" combination. Therefore, this embodiment specifically ensures that the weft yarns contribute appropriately to visual texture and mechanical properties within a target weight range.
[0085] The weft yarn can be any type of yarn, such as staple fiber yarn, filament yarn or a mixture thereof, can be produced by any yarn production method, such as ring spinning or open spinning, and can be composed of or made of any material, such as natural fibers, such as cotton, or synthetic filaments, such as polyester.
[0086] In exemplary embodiments of any of the foregoing aspects of the invention or of its embodiments, the weft yarn is particularly composed of short fibers, especially cotton fibers. This embodiment introduces the material and structure of the weft yarns, matching them with the aesthetic and tactile properties of the coarser first set of warp yarns, and supporting the invention's goal of achieving both a visually substantial feel and soft, flexible performance. Using short fibers, particularly cotton, as the weft yarn contributes to a natural, fluffy surface texture and the traditional look typically associated with heavy-duty woven fabrics such as denim, twill, and canvas. Short-fiber weft yarns are particularly preferably used in combination with short-fiber rovings to enhance the interweaving stability with both sets of warp yarns. This combination reinforces its initial intention: to simulate the look of heavy-duty fabrics using natural, familiar materials, while simultaneously achieving a lighter feel within the second set of warp yarns. Particularly in this embodiment, the weft yarn may be composed entirely of cotton fibers, or may contain cotton-rich blends, such as a combination of at least 80 wt% cotton with other fibers, such as polyester, for example, 20 wt% polyester. The weft yarn may comprise or consist of ring-spun yarns and / or open-spun yarns. However, as stated above, the use of cotton fibers as the weft yarn is merely exemplary. Weft yarns can be made of any type, produced by any method, and composed of or constituted of any material.
[0087] In any of the foregoing aspects of the invention or embodiments thereof, the warp density of the first set of warp yarns is less than 24 yarns / cm.
[0088] Because the warp yarn count of the first group of warp yarns is lower than that of the second group of warp yarns, in the following text, the warp yarns of the first group of warp yarns will be referred to as "roving" or "first group of warp yarns," and the warp yarns of the second group of warp yarns will be referred to as "spinning" or "second group of warp yarns." However, it should be clear that this reference is for ease of reading this disclosure only. In any case, the expressions "roving" or "spinning" should not be construed as limiting the warp yarn count of the first group of warp yarns or the second group of warp yarns, except for the limitation that the warp yarn count of the second group of warp yarns is lower than that of the first group of warp yarns.
[0089] The reduced warp density of the first set of warp yarns (rovings) results in a lighter and softer fabric without compromising its heavy visual appearance, as the rovings dominate the fabric surface. The second set of warp yarns, with its lower warp count (fine yarns), compensates for the reduced structural cohesion caused by the reduced interlacing frequency of the rovings. Thanks to the lower warp count of the fine yarns, the fabric weight increases only slightly, thus reducing overall weight. In summary, this embodiment provides a lightweight fabric with a substantial appearance, while maintaining a stable and slip-resistant overall structure.
[0090] The term "first group of warp yarns" can also be expressed as "main warp yarns," "coarse warp yarns," or "first group of warp yarns." The term "second group of warp yarns" can also be called "auxiliary yarns," "stabilizing yarns," "fine warp yarns," or "second group of warp yarns."
[0091] The term "short fiber" can include natural or regenerated fibers such as cotton, flax, viscose, or mixtures thereof.
[0092] The first group of warp yarns is preferably composed of cotton or a cotton-rich blend (e.g., cotton / polyester), with a yarn count preferably between 600 and 1000 dtex, for example, corresponding to roving used for denim or similar heavy-duty fabrics. The preferred warp density of the first group is likely between 10 and 20 yarns per centimeter, more preferably between 12 and 16 yarns per centimeter. The second group of warp yarns is preferably inserted between each roving warp yarn in a 1 / 1 plain weave and can be visually and tactilely concealed by the thicker yarns in the first group. The second group is preferably positioned alternately or staggered to ensure a uniform distribution of the joining points and consistent structural stability across the entire fabric width.
[0093] The "warp density" or "weft density" used in this article can be measured according to DIN EN 1049-2, ASTM D3775, or equivalent standards. Measurement is best performed when the fabric is in a relaxed state, by calculating the number of warp yarns over a given length and converting it to a value per centimeter.
[0094] "Yarn count," also known as "linear density," can be expressed in tex (tex), dtex (dtex), ne (Ne), metric count (Nm), or denier. Yarn count can be determined according to ISO 2060. The terms "high yarn count" or "low yarn count" used here refer to a comparison of count / density values expressed in tex, dtex, or denier.
[0095] In the context of this invention, particularly in order to determine warp density, yarn count, and their product as count density, conditions for the fabric sample used for measurement can be specified.
[0096] Unless otherwise stated, fabric parameters relevant to this invention, such as yarn count, warp density, weft density, yarn count density, fabric weight, and seam density, should be measured with the woven fabric in a relaxed state, for example, after removal from the loom, and preferably without any post-weaving treatments, such as washing, shrinkage, setting, mercerizing, or finishing. It is preferable to allow the fabric to relax naturally at ambient temperature and humidity for at least 24 hours after removal from the loom, laid flat and unrestricted, to eliminate residual tension from the weaving process. This "off-loom relaxation" state reflects the actual weave structure before any dimensional changes caused by wet or heat treatment processes are introduced. Particularly preferred is that fabric samples are treated according to ISO 139 standards, typically at 20°C ± 2°C and 65% ± 4% relative humidity for at least 24 hours, and then the fabric parameters, such as yarn count and yarn density, are measured.
[0097] While the off-machine relaxed state is the primary measurement reference, in-machine and finishing conditions can also be decisive, depending on the intended use or specification control. For in-machine conditions, measurements are taken directly on the loom. For finishing conditions, measurements taken after washing, shrinkage, or finishing may reflect the dimensions for the final use, particularly for garments or home textiles. Regarding washing, measurements can be taken after a washing cycle specified according to ISO 6330.
[0098] In any of the foregoing aspects or embodiments thereof, in one implementation, the first set of warp yarns has a warp density of less than 20 yarns / cm, preferably less than 18 yarns / cm, more preferably less than 16 yarns / cm, most preferably less than 14 yarns / cm, and / or at least 6 yarns / cm, preferably at least 8 yarns / cm, more preferably at least 10 yarns / cm, and most preferably at least 12 yarns / cm. The inventors have found that the upper limit ensures that the coarse warp system exists within a density range that balances structural functionality and aesthetic contributions. In particular, a density below 20 yarns / cm can reduce fabric weight and improve drape and softness, while still maintaining sufficient surface clarity through the retention of a large number of rovings. The lower limit, particularly at least 6 yarns / cm, ensures that the fabric maintains a coherent structure without gaps or excessive slippage, especially when the secondary warp system has not yet fully compensated. A narrower preferred range (e.g., 10-14 yarns / cm) provides practical design guidance for optimizing the fabric's apparent weight, low weight, and structural integrity.
[0099] When the yarn count of the first set of warp yarns is in the range of 750-850 dtex, a warp density of 10 to 14 threads / cm is particularly preferred. Densities below 12 threads / cm are advantageous for softer, more draping fabrics (e.g., those intended for casual or fashion wear). For applications requiring stiffer, more structured fabrics (e.g., outerwear or jeans), densities closer to the upper end of the range (16-18 threads / cm) can be used.
[0100] In one embodiment of any of the foregoing aspects or embodiments thereof, the first set of warp yarns has a count density that can be calculated by multiplying the warp density of the first set of warp yarns by the yarn count of the warp yarns, and is less than 18,000 dtex / cm. Preferably, the fabric is a woven fabric. In particular, count density, as a comprehensive indicator, reflects both the fineness (yarn count) and yarn density (yarn count per centimeter) of the first set of warp yarns. In particular, yarn count density expresses the warp quality per unit width, especially in the weft direction, providing a more refined control parameter than yarn count or density alone. Limiting the count density of the first set of warp yarns to below 18,000 dtex / cm ensures that even with the use of roving, the overall warp quality remains low, thereby directly contributing to reducing the weight of fabrics with a bulky appearance. In particular, this allows the use of roving at a relatively low density without exceeding a quality threshold, thereby promoting a visually substantial feel and a sense of volume in the textile without compromising comfort and drape.
[0101] The term "count density" can also be referred to as linear mass density per unit width, or linear weight concentration of warp yarns. The characteristic "count density, which can be calculated by multiplying the warp density of the first group of warp yarns by the yarn count of the first group of warp yarns, is less than 18,000 dtex / cm, and can also be expressed as 'the linear mass density per unit width of the first group of warp yarns is less than 18,000 dtex / cm.'"
[0102] The "yarn count density" used in this article can be calculated by multiplying the yarn count and warp density, for example, using the following formula:
[0103] Yarn count density (dtex / cm) = Yarn count (dtex) × Warp density (yarn / cm)
[0104] For example, a roving with a yarn count of 800 dtex and a warp density of 20 yarns / cm has a yarn count density of 1.600 dtex / cm (800 × 20 = 16,000 dtex / cm).
[0105] Preferably, the yarn count of the first set of warp yarns can be between 700 and 900 dtex, with the density adjusted to remain below the 18,000 dtex / cm threshold. For example, yarns with a count of 850 dtex can be used, with a maximum density of 21 yarns / cm; while using thicker 1000 dtex yarns, a maximum density of 18 yarns / cm is required to meet the limit. These configurations allow for a customizable, substantial look and weight of the fabric, while the structural integrity is supported by the second set of warp yarns.
[0106] In any of the foregoing aspects of the invention or embodiments thereof, the linear density of the first set of warp yarns is 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 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 provides a fine upper and lower limit range for the linear density of the first set of warp yarns, ensuring an optimal balance between low weight, mechanical integrity, and a substantial appearance. A linear density below 17,000 dtex / cm (especially below 12,000 dtex / cm) is particularly helpful in limiting the fabric mass per unit area, which is beneficial for producing lightweight yet heavy-feeling fabrics. A minimum yarn linear density of at least 6,000 dtex / cm ensures sufficient material and friction interface to maintain anti-slip properties and dimensional stability, which is particularly beneficial when using lower warp densities. A narrower preferred range (e.g., 10,500–11,500 dtex / cm) provides a combination of a robust appearance and low weight, while maintaining sufficient interfiber friction to prevent deformation during wear and washing.
[0107] In a particularly preferred embodiment, the first set of warp yarns has a yarn count of 750 to 900 dtex and a warp density of 12 to 14 yarns / cm, resulting in a yarn linear density of 9,000 to 12,500 dtex / cm. These ranges have been found to offer an ideal compromise between visually heavy fabrics and lightweight construction, sufficient to prevent slippage between yarns under typical garment use conditions, and compatibility with standard weaving equipment and industrial yarn supplies. Furthermore, or alternatively, the use of a 3 / 1 or 2 / 2 twill weave has shown particular effectiveness for the first set of warp yarn systems within these ranges, as such patterns maximize yarn exposure and visual impact even at medium densities.
[0108] In any of the foregoing aspects of the invention or in one embodiment of an embodiment thereof, the second set of warp yarns has a warp density of at least 8 yarns / cm. Preferably, the fabric is woven. In one embodiment, a minimum warp density of the second set of warp yarns is introduced, which provides a stabilizing effect in the fabric structure. The second set comprises, preferably, finer synthetic filament yarns, particularly hidden among the coarser main warp yarns of the first set. The minimum density of 8 yarns / cm ensures a meaningful contribution of the second set of warp yarns to the bonding density, especially if it is woven in a 1 / 1 plain weave or a similarly tight pattern. The increased interlacing frequency between the second set of warp yarns and the weft yarns compensates for the low density of the first set of warp yarns, improving the dimensional stability, slip resistance, and tear strength of the fabric. At this density, the second set of warp yarns specifically creates an internal reinforcing network that stabilizes the entire textile structure without interfering with the surface appearance or hand feel.
[0109] The second set of warp yarns is preferably composed of synthetic filaments, such as polyester or nylon, with a yarn count of less than 150 dtex, preferably less than 100 dtex, as further described in the present disclosure. The second set of warp yarns is preferably woven in a 1 / 1 plain weave, interlacing with each weft yarn to maximize the number of bonding points. Particularly preferred is that the density of the second set of warp yarns is between 10 and 14 yarns / cm, which, combined with the yarn count, ensures structural reinforcement while adding minimal weight, and because it is hidden among the coarse yarns, does not significantly alter the fabric surface.
[0110] The two warp systems can be inserted alternately (e.g., coarse-fine-coarse-fine...) or grouped in a structured ratio (e.g., 1 coarse to 1 fine), depending on the desired balance of fabric stiffness, drape, and process compatibility.
[0111] In any of the foregoing aspects of the invention or any embodiment thereof, the warp density of the second warp group is at least 9 yarns / cm, preferably at least 10 yarns / cm, more preferably at least 11 yarns / cm, more preferably at least 12 yarns / cm, most preferably at least 13 yarns / cm, and / or less than 50 yarns / cm, preferably less than 40 yarns / cm, more preferably less than 30 yarns / cm, more preferably less than 20 yarns / cm, and most preferably less than 15 yarns / cm. This provides precise lower and upper limits for the warp density of the second warp group, providing a precisely controllable design range to balance mechanical reinforcement and fabric softness and flexibility. In particular, the increase in the minimum value of at least 9 yarns / cm increases the bonding density, especially when the second warp group is woven in a tight weave pattern (e.g., 1 / 1 plain weave), enhancing anti-slippage and dimensional stability. The upper limit of less than 50 yarns / cm, preferably less than 15 yarns / cm, ensures that the fabric does not become too stiff or dense, negatively impacting drape, softness, or breathability. These ranges allow designers to fine-tune the influence of the second set of warps based on the main warp density, yarn count, and target application (e.g., lightweight shirts versus structured denim-like fabrics).
[0112] Studies have shown that the preferred warp density for the second set of warp yarns is between 10 and 14 ends / cm, which not only provides sufficient interlacing frequency for mechanical reinforcement but also has limited impact on weight and fabric thickness, and excellent compatibility with fine synthetic yarns of 50-100 dtex. For example, a combination of 12 ends / cm fine warp yarns with 70 dtex yarns contributes a linear density of 840 dtex, which significantly enhances the internal bonding structure. In fabrics requiring maximum softness, a fine warp density of 10-11 ends / cm provides a good balance between support and drape. Similarly, it is also preferable for the second set of warp yarns to be interlaced in a different weave pattern than the first set (e.g., plain weave versus twill), as this increases the distribution of bonding points and prevents float alignment, thereby improving slip resistance.
[0113] In any of the foregoing aspects of the invention or an embodiment thereof, the yarn linear density of the second warp yarns can be calculated by multiplying the warp density of the second warp yarns by the yarn count of the second warp yarns, and is at least 700 dtex / cm. The "at least 700 dtex / cm" yarn linear density of the second warp yarns can also be expressed as the second warp yarns containing at least 700 dtex / cm of total linear mass per unit fabric width. Preferably, the fabric is woven. This embodiment defines a minimum yarn linear density threshold for the second warp yarn system, ensuring that even when using fine (low count) yarns, it provides sufficient structural support for the woven fabric. Introducing a yarn linear density threshold ensures precise control of the total linear mass per unit width. The fineness of the second warp yarns reaches a level that significantly contributes to the fabric's bonding density, slip resistance, and dimensional stability. The 700 dtex / cm threshold ensures that even when using very fine yarns (e.g., 70 dtex), the warp density is sufficient (e.g., ≥10 yarns / cm) to provide structural integrity. This gives the fabric a visually substantial feel and low weight, offsetting the structural weaknesses of the coarse, low-density first set of warp yarns through high-frequency, fine weaving, and in particular, forming an "invisible reinforced mesh".
[0114] The fineness of the second set of warp yarns is preferably between 50 dtex and 100 dtex, and is used at a density of at least 10 warp yarns per centimeter, more preferably between 11 and 13 warp yarns per centimeter, thereby producing a yarn count density range of 700-1300 dtex / cm. This configuration particularly ensures an increase in the number of bonding points per square centimeter (especially in plain weave), a reduced visual impact because the fine yarns are hidden under the coarser warp system, and minimal increase in the overall fabric weight, maintaining the lightweight characteristics of the invention.
[0115] In any of the foregoing aspects and embodiments thereof, the count density of the second set of warp yarns is 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 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, and most preferably less than 1,100 dtex / cm. These defined ranges allow for precise control over the mechanical reinforcement provided by the fine synthetic yarns, while avoiding excessive use of material and structural rigidity. The minimum count density of 750-1,000 dtex / cm ensures that the second set of warp yarns provides sufficient internal weaving strength, which is particularly beneficial when the warp density of the first set of warp yarns is low. The upper limit is limited to 1,100-6,000 dtex / cm to prevent the auxiliary warp system from becoming too dense, which would unnecessarily increase the fabric weight, stiffen the structure, and even obscure the fabric's intended look and drape. This range allows for structural integrity while maintaining lightweight filaments, and the stabilizing system can be non-invasively concealed beneath the fabric surface.
[0116] Preferably, the count density of the second set of warp yarns is between 750 and 1,100 dtex / cm, more preferably between 800 and 1,000 dtex / cm. In a preferred embodiment, the second set of warp yarns comprises, specifically, 70 to 90 dtex synthetic filament yarns (e.g., polyester) and is used at a density of 10 to 14 warp yarns per centimeter, particularly producing a count density of 700 to 1,300 dtex / cm. When extremely high structural rigidity is required, such as in technical or furniture fabrics, count densities exceeding 1,100 dtex / cm can be used, but this is less ideal for apparel applications due to reduced flexibility and comfort.
[0117] A fourth aspect of the invention relates to a method for weaving a fabric according to any one of the first to third aspects or embodiments thereof, the method comprising the step of weaving a first set of warp yarns, a second set of warp yarns, and weft yarns into a fabric, wherein the warp yarns of the second set of warp yarns have a lower yarn count than the warp yarns of the first set of warp yarns, and wherein the ratio of the warp density of the first set of warp yarns to the warp density of the second set of warp yarns is less than 2 / 1. The method according to the fourth aspect of the invention can be performed in a manner that results in a fabric as described in any one of the first to third aspects or embodiments thereof.
[0118] The fifth aspect of the invention relates to a method for weaving a fabric according to the fourth aspect, particularly according to any one of the first to third aspects or embodiments thereof, comprising the step of weaving a first set of warp yarns, a second set of warp yarns, and weft yarns into a fabric, wherein the warp yarns of the second set of warp yarns have a lower yarn count than the warp yarns of the first set of warp yarns, and wherein the fabric has a bond density of at least 3,500 bond points / gram. The method according to the fifth aspect of the invention can be performed in a manner that results in a fabric as described in any one of the first to third aspects or embodiments thereof.
[0119] A sixth aspect of the invention relates to a method for weaving a fabric according to a fourth or fifth aspect, particularly according to one of the first to third aspects or embodiments thereof, comprising the step of weaving a first set of warp yarns, a second set of warp yarns, and weft yarns into a fabric, wherein the warp yarns of the second set of warp yarns have a lower yarn count than the warp yarns of the first set of warp yarns, the fabric has a weight of less than 375 g / m², and wherein the warp yarns of the first set of warp yarns have a yarn count of at least 770 dtex. The method according to the sixth aspect of the invention can be performed in a manner that results in a fabric as described in one of the first to third aspects or embodiments thereof.
[0120] In particular, as a general concept of this disclosure—and not to be construed as limiting the scope of the invention—it is said to provide a fabric comprising two sets of different warp yarns: a first set of warp yarns, preferably comprising short fibers, more preferably cotton fibers, which are relatively coarse and arranged at a defined low warp density; and a second set of warp yarns, preferably comprising synthetic filaments, more preferably polyester fibers, which are finer than the yarns of the first set of warp yarns, for example having a lower yarn count. The second set of warp yarns is preferably interwoven with the weft yarns in a tighter weave pattern than the first set of warp yarns, preferably a 1 / 1 plain weave, while the first set of warp yarns is preferably interwoven in a coarser weave pattern, such as a twill weave. This difference in weave pattern particularly ensures that the second set of warp yarns contributes more bonding points to the fabric without significantly altering the external appearance or increasing the weight of the fabric. The second set of warp yarns is preferably located between the yarns of the first set of warp yarns, particularly mostly obscured by them, such that the roving determines the visual and tactile impression of the fabric (i.e., its “heavy” appearance), while the finer yarns of the second set of warp yarns stabilize the internal structure and ensure resistance to slippage. By carefully adjusting the yarn density and count density of the two sets of warp yarns, the present invention provides a fabric construction that maintains dimensional stability and mechanical strength even when using a lower total yarn count and achieving a significant reduction in fabric weight.
[0121] Therefore, the fabrics according to the present invention offer several technical advantages over conventional woven fabric constructions, such as being lightweight yet appearing substantial (using short, coarse yarns to reduce density creates a visually heavy fabric appearance while maintaining low overall fabric weight), excellent anti-slip properties at low density (the second set of warp yarns significantly increases the number of interlacing (bonding) points with the weft yarns, ensuring structural integrity even at lower overall yarn density), dimensional stability (the present invention provides sufficient internal cohesion to prevent slippage and deformation, especially in garments subjected to mechanical stress), softness and drape (the reduced total yarn density helps to create a softer, more flexible fabric structure, ideal for applications requiring comfort, such as casual wear and loungewear), high material efficiency (the design minimizes the need for high yarn consumption, particularly coarse yarns, providing cost and resource benefits during production), and design flexibility (by separating fabric weight from visual substantiality and structural integrity, the present invention allows for new combinations of fabric aesthetics and performance that are unattainable with conventional weaving strategies).
[0122] In the following description, similar or identical features will be indicated by similar or identical reference symbols.
[0123] Figure 1 A fabric 1 is shown, having a first set of warp yarns 3, also referred to as "roving" or "first set of warp yarns," and a second set of warp yarns 5, also referred to as "fine yarn" or "second set of warp yarns." The weft yarns are indicated by reference symbol 7. The fine yarn 5 has a lower yarn count than the roving 3, which is illustrated schematically by using lines that are finer than the roving 3.
[0124] Figure 2 A fabric 1 is shown, comprising coarse warp yarns 3 and weft yarns 7. However, as... Figure 2 All the coarse warp yarns 3 shown are of the same thickness, and the fabric 1 does not include a second group of warp yarns with a yarn count lower than that of the coarse warp yarns, thus failing to meet the requirements of the present invention.
[0125] By comparison Figure 1 and Figure 2 It can be seen that adding fine warp yarn 5 to fabric 1 containing coarse warp yarn 3 can significantly increase the number of bonding points per square centimeter, while the increase in fabric weight is much smaller due to the low yarn count of the fine warp yarn. As an alternative to increasing the number of bonding points per square centimeter, the present invention also allows for reducing fabric weight by replacing coarse warp yarn with fine yarn, so as to provide a certain number of bonding points per square centimeter while maintaining a lower fabric weight.
[0126] In this context, as described above, the additional connection points provided by the fine warp yarns can be used to reduce the warp density of the coarse warp yarns to less than 24 yarns per centimeter, thereby providing a fabric that appears heavy (provided by the coarse warp yarns), lightweight (achieved by replacing the thick coarse warp yarns with fine warp yarns), and structurally complete (thanks to the same or even more connection points / cm). As mentioned above, this heavy appearance combined with low weight can also be achieved in the range of less than 24 yarns per centimeter, for example, when the yarn count of the coarse warp yarns is very high, such as a count density of less than 18,000 dtex / cm. The same applies to a minimum of at least 8 warp yarns to provide sufficient connection points through the fine warp yarns, and a count density of at least 700 dtex, providing sufficient connection points / cm even if the weft density itself is not outside the scope of this invention. Furthermore, to achieve a meaningful effect in weight reduction, it is recommended that the number of fine warp yarns used be less than the number of coarse yarns, i.e., the ratio of coarse warp yarn density to fine warp yarn density is less than 2 / 1 (first and fourth aspects of the invention), meaning that the number of coarse warp yarns used is less than twice that of fine warp yarns. In addition, by reducing fabric weight by replacing coarse warp yarns with finer warp yarns, the bonding density can be increased to more than 3,500 bonding points per gram (second and fifth aspects of the invention), enabling the fabric to achieve high structural integrity with low weight. Last but not least, by replacing coarse warp yarns with finer warp yarns, fabrics with a yarn count of at least 770 dtex (providing a heavy appearance) can be provided, combined with lightweight fabrics weighing less than 375 grams per square meter (third and sixth aspects of the invention).
[0127] Comparative example
[0128] Figure 2 A comparative example of a fabric 1 not described in this invention is shown. As shown, the coarse warp 3 in Example 1 is woven into a 3 / 1 twill weave, and the weave factor F of the weft 7 is 0.25. In the "off-machine relaxed state," the warp density of the coarse warp is 26.88 yarns / cm, and the weft density of the weft is 18 yarns / cm. Therefore, preferably in the "off-machine relaxed state," the fabric of Comparative Example 1 has 120.96 bonding points / cm² (0.25 × (26.88 × 18)). Both the coarse warp and weft are cotton yarns with a yarn count of 843 dtex. Correspondingly, the yarn count density of the coarse warp is 22.660 dtex / cm. This fabric, preferably in the "off-machine relaxed state," weighs 440 grams per square meter, resulting in a bonding point density of 2.749 bonding points per gram.
[0129] Example 1
[0130] Figure 1 The diagram shows the weave pattern of fabric 1 according to Embodiment 1 of the present invention. For example... Figure 1As shown, in Example 1, the coarse warp yarn 3 is woven in a 3 / 1 twill weave, while the fine warp yarn 5 is woven in a 1 / 1 plain weave. It can be seen that the coarse warp yarn 3 and the fine warp yarn 5 change one yarn after another, meaning the ratio of coarse warp yarn density to fine warp yarn density is 1:1. Because the fine warp yarn uses a 1 / 1 plain weave (weave factor = 0.5), the number of bonding points provided by the fine warp and weft yarns is twice that of the coarse warp yarn in a 3 / 1 twill weave (weave factor F = 0.25). In the "off-machine relaxed state," the warp yarn density of the coarse warp yarn is 13.44 ends / cm, the warp yarn density of the fine warp yarn is also 13.44 ends / cm, and the weft yarn density is 15 ends / cm. Therefore, in the "off-machine relaxed state," the bonding point density of the fabric in Example 1 is 151.2 bonding points / cm. 2 The roving provides 50.4 bonding points / cm. 2 (0.25×(13.44×15)), the fine warp yarn provides 100.8 bonding points / cm. 2 (0.5 × (13.44 × 15)). Both the coarse warp and weft yarns are 843 dtex cotton yarn. The fine warp yarn is 78 dtex polyester filament yarn. Accordingly, the unit linear density of the first group of warp yarns is 11.330 dtex / cm, while the unit linear density of the second group of warp yarns is 10.048 dtex / cm. The fabric preferably has a weight of 305 g / m² in its "off-machine relaxed state". 2 This results in a binding site density of 4.957 binding sites / g.
[0131] In summary, Example 1 has a lower weight (305 g / m²) compared to the comparative example. 2 Comparison 440g / m 2 Higher number of bonding points / cm 2 (151.2 vs. 120.96), thus also having a higher binding point density (4.957 vs. 2.749).
[0132] Therefore, Example 1 appears heavy because it has thick (coarse) warp yarns, while its weight is lower due to the replacement of coarse warp yarns with fine warp yarns, and slippage problems are avoided (due to the higher number of bonding points provided by the fine warp yarns). In other words, Example 1 is a lightweight fabric with low density that appears heavy but has no slippage issues, and is softer and has better drape due to the reduced warp density of the coarse warp yarns.
[0133] Figure 3 schematically shown Figure 1A top view of the fabric after finishing treatments (such as shrinkage). During the finishing process, the fabric typically shrinks in both the warp and weft directions, which results in the fine warp yarns (due to their lower yarn count) being covered by the coarse warp yarns. This is somewhat beneficial because it hides the fine warp yarns inside the fabric so that the fine yarns do not interfere with the heavy appearance provided by the coarse yarns.
[0134] Figure 4 Schematic illustration along Figure 3 The cross-sectional view of the AA line schematically shows the extension of the coarse warp 3 and fine warp 5 in the warp direction after completion. Figure 5 This shows that after Example 1 is completed, the fine warp 5 is essentially hidden between the two coarse warp 3.
[0135] Example 2
[0136] Figure 6 The diagram schematically shows the weaving pattern of the fabric 1 of the present invention, which differs from that of the fabric 1 in the fact that the number of fine warp yarns in the fabric 1 is twice that of coarse warp yarns, that is, each coarse warp yarn is followed by two fine warp yarns 5. These fine warp yarns are woven in a 1 / 1 plain weave, and the upper and lower parts of adjacent fine warp yarns 5 are staggered in the weft direction.
[0137] Example 3
[0138] Figure 7 The diagram schematically shows the weaving pattern of fabric 1 according to embodiment 3 of the present invention. The difference between embodiment 3 and embodiment 2 is that the upper and lower layers of adjacent fine warp yarns 5 are covered from both sides by coarse warp yarns in the weft direction and are not offset in the warp direction, that is, they are aligned in the warp direction.
[0139] Example 4
[0140] Figure 8 The schematic diagram shows the weaving pattern of fabric 1 according to any aspect of the invention, embodiment 4, the only difference between embodiment 4 and embodiment 1 being that each pair of fine warp yarns 5 is followed by three coarse warp yarns 3 on both sides of the weft direction.
[0141] Example 5
[0142] Figure 9 The diagram schematically illustrates the weaving pattern of fabric 1 according to embodiment 5, the only difference between embodiment 5 and embodiment 1 being that the density ratio of roving to fine warp is not 1 / 1, but 4 / 3. In the weft arrangement, a single fine warp 5 is alternately followed by a single roving and a pair (i.e., two) rovings.
