Description

Technical Field

[0001] This invention relates to the field of fabric technology, and in particular to a silk-wool composite fabric and its weaving method. Background Technology

[0002] To balance warmth, skin-friendliness, and durability, various composite fabric solutions have been proposed in existing technologies. Common composite methods involve bonding different functional fabric layers together using adhesives or quilting. Adhesive bonding can clog the gaps between fibers, affecting the fabric's breathability and feel, and may lead to delamination and bubbling after repeated washing. Quilting involves sewing multiple layers of fabric together with needle and thread, increasing production steps and costs, leaving needle marks on the fabric surface, affecting aesthetics, and the needle holes at the quilting points can reduce the fabric's warmth retention.

[0003] In the field of composite yarn technology, blending wool with fibers such as silk and cotton is a common approach to improve the performance of wool fabrics. Blended yarns can combine the advantages of different fibers; for example, a wool-silk blend can balance warmth and smoothness, while a wool-cotton blend can improve moisture absorption and breathability. However, simple blending yarn technology has the following limitations: some wool fibers in the blended yarn will still be exposed on the yarn surface, which can still cause itching when in contact with the skin, failing to fundamentally solve the skin-friendliness problem; the uniform mixing of various fiber components in the blended yarn cannot form a functional gradient, and warmth and silkiness cannot be optimized and maximized at different levels; single-layer fabrics made from blended yarns cannot simultaneously achieve the effects of a skin-friendly inner surface and a glossy outer surface.

[0004] Therefore, the existing technology still needs further development and improvement. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention proposes a silk-wool composite fabric and its weaving method, aiming to solve the issues of poor skin-friendliness, pilling tendency, and wrinkle-prone, abrasion-sensitive nature of pure wool fabrics in existing technologies. Specifically: In a first aspect, a silk and wool composite fabric includes, in sequence, an inner layer, a wool composite layer and an outer layer. The inner layer is woven from yarn made of a blend of mulberry silk fibers and cotton fibers; The wool composite layer is disposed between the inner layer and the outer layer, and is made of interwoven warp and weft yarns. The warp yarns are a blend of mulberry silk fiber, wool fiber and cotton fiber, and the weft yarns are a blend of wool fiber, mulberry silk fiber, cotton fiber and nylon fiber. The outer layer is woven from yarn made of a blend of wool fibers, silk fibers and cotton fibers; The inner layer, wool composite layer, and outer layer are woven into a single structure through three independent warp yarn systems.

[0006] The following are preferred technical solutions of the present invention, but are not intended to limit the technical solutions provided by the present invention. The purpose and beneficial effects of the present invention can be better achieved and realized through the following preferred technical solutions.

[0007] As a preferred technical solution, the silk-wool composite fabric wherein the yarn of the inner layer is a blended double-ply yarn of 55wt% to 65wt% mulberry silk and 35wt% to 45wt% cotton.

[0008] As a preferred technical solution, the silk-wool composite fabric wherein the warp yarn of the wool composite layer is a blended single yarn of 45wt%–55wt% mulberry silk, 30wt%–40wt% wool, and 10wt%–20wt% cotton; and the weft yarn of the wool composite layer is a blended single yarn of 40wt%–45wt% wool, 25wt%–30wt% mulberry silk, 15wt%–20wt% cotton, and 5wt%–8wt% nylon.

[0009] As a preferred technical solution, the silk and wool composite fabric wherein the yarn of the outer layer is a blended double-ply yarn of 35wt% to 45wt% wool, 15wt% to 25wt% mulberry silk and 35wt% to 45wt% cotton.

[0010] As a preferred technical solution, the silk-wool composite fabric wherein the yarn specification of the inner layer is 40S / 2 double-ply yarn with a twist coefficient of 280-320; and the yarn specification of the outer layer is 60S / 2 double-ply yarn with a twist coefficient of 290-330.

[0011] As a preferred technical solution, in the silk-wool composite fabric, the warp yarn of the wool composite layer is 60S single yarn with a twist coefficient of 320-360; the weft yarn of the wool composite layer is single yarn.

[0012] As a preferred technical solution, the silk-wool composite fabric comprises, wherein the inner layer of mulberry silk fibers are 1.2D to 1.5D cut short fibers with a length of 38mm to 51mm; the wool composite layer and the outer layer of wool fibers are 16μm to 18μm ultrafine wool cut short fibers with a length of 35mm to 45mm; and the outer layer of mulberry silk fibers are 20D to 30D semi-dull filaments.

[0013] Secondly, a method for weaving the aforementioned silk-wool composite fabric, comprising: A multi-axis, multi-healer loom is used, and the tension and warp feed speed of the outer layer warp yarn, the wool composite layer warp yarn, and the inner layer warp yarn are controlled by three independent warp yarn systems respectively; During weaving, the outer layer warp yarns and wool composite layer weft yarns are interwoven with a 3-up-1-down floating ratio, the wool composite layer warp yarns and wool composite layer weft yarns are interwoven with a 2-up-2-down floating ratio and selectively connected with the warp yarns of the outer layer and inner layer, and the inner layer warp yarns and wool composite layer weft yarns are interwoven with a 1-up-3-down floating ratio, forming an integral weaving.

[0014] As a preferred technical solution, in the aforementioned weaving method, the outer layer warp yarns float on the fabric surface, the inner layer warp yarns sink to the bottom layer of the fabric, and the wool composite layer warp yarns are interwoven between the outer layer and the inner layer.

[0015] Thirdly, a garment product, wherein the aforementioned silk and wool composite fabric is used.

[0016] Beneficial effects: Compared with existing technologies, this invention adopts a three-layer functionally separated composite structure design. The inner layer, mainly made of mulberry silk, addresses the issue of skin-friendliness; the wool composite layer, mainly made of wool, provides warmth; and the outer layer balances silky luster and abrasion resistance. Each of the three layers performs its specific function, achieving functional integration through integrated weaving, thus solving the technical challenge that single-fiber fabrics cannot simultaneously meet multiple performance requirements such as warmth, skin-friendliness, and abrasion resistance. The integrated weaving process avoids the defects of traditional composite processes. Through three independent warp yarn systems working in conjunction with a special interlacing pattern, the fabric is woven in one go, eliminating the need for adhesives for interlayer bonding, thus eliminating the impact of adhesives on breathability and hand feel, and preventing delamination issues after washing. Simultaneously, the quilting process is eliminated, leaving no needle marks on the fabric surface, maintaining aesthetic integrity, simplifying the production process, and reducing manufacturing costs.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0025] Combination Figures 1 to 2 As shown, the silk and wool composite fabric of the present invention has a three-layer integrated weaving structure, which includes an inner layer, a wool composite layer and an outer layer from the inside to the outside.

[0026] The innermost layer, located on the innermost side of the silk-wool composite fabric, is in direct contact with the wearer's skin. This layer is made of a blend of mulberry silk and cotton. The smooth, scale-free surface of mulberry silk fibers provides a low-friction, close-fitting feel, preventing itching. The addition of cotton fibers helps absorb sweat from the skin's surface and wick it to the middle layer, keeping the skin dry.

[0027] The wool composite layer, located between the inner and outer layers, is the core layer for the fabric's warmth retention. This layer consists of a stable fabric structure formed by the interweaving of warp and weft yarns. The warp yarns are primarily composed of mulberry silk fibers, combined with wool and cotton fibers, while the weft yarns incorporate nylon fibers into these three fiber bases. The wool composite layer serves to support and connect the inner and outer layers along the fabric's thickness.

[0028] The outermost layer, located on the far side of the fabric, is the layer that provides both visual and tactile appearance. This layer is made from a blend of wool, silk, and cotton. The silk fibers in the outer layer are in a semi-dull filament form, unlike the cut short fibers used in the inner and wool composite layers. This filament form provides better luster, surface smoothness, and pilling resistance.

[0029] The three fabric layers are woven together using three independent warp systems in conjunction with the weft yarns. During the weaving process, the outer layer warp yarns are mainly distributed on the fabric surface to form a covering, the inner layer warp yarns are mainly deposited at the bottom of the fabric to form the inner surface, and the wool composite layer warp yarns are interwoven in the middle to connect the upper and lower layers. The three layers are connected as a whole through the selective connection of the warp yarns at the interlacing points, without the need for adhesives or quilting for fixation.

[0030] In one implementation of this embodiment, the inner warp yarn is a blended double-ply yarn of mulberry silk and cotton. Mulberry silk accounts for 55% to 65% of the yarn mass, and cotton accounts for 35% to 45%. The mulberry silk uses 1.2D to 1.5D cut short fibers with a fiber length of 38mm to 51mm. The cotton fiber is combed cotton with a fiber fineness of approximately 1.5D and a fiber length of 29mm to 33mm. The finished yarn is a 40S / 2 double-ply yarn with a twist coefficient controlled within the range of 280 to 320 and a yarn strength of not less than 11cN / tex.

[0031] The inner layer is made of a blend of chopped mulberry silk and cotton fibers. Compared to pure cotton or pure mulberry silk linings, its advantages are: mulberry silk fibers have a smooth surface, naturally skin-friendly, and their triangular cross-section reflects light, giving the fabric a soft sheen; cotton fibers have a hollow structure with good moisture absorption, absorbing sweat from the skin and releasing it to the middle layer. The two fibers are evenly distributed across the yarn cross-section. When in contact with the skin, the smooth mulberry silk fibers preferentially contact the skin surface, reducing the overall coefficient of friction.

[0032] The reason for using a double-ply yarn structure is that double-ply yarn has better uniformity and abrasion resistance than single yarn, making it suitable as an inner layer that comes into direct contact with the wearer's skin. A higher proportion of mulberry silk (55% to 65%) ensures a soft and skin-friendly feel on the inner surface, while the proportion of cotton fibers (35% to 45%) provides the necessary moisture absorption, breathability, and shape stability.

[0033] The warp yarn of the wool composite layer is a blend of mulberry silk, wool, and cotton. Mulberry silk comprises 45% to 55%, wool 30% to 40%, and cotton 10% to 20%. The mulberry silk uses 1.2D to 1.5D cut staple fibers with a length of 38mm to 51mm. The wool uses 16μm to 18μm ultrafine wool cut staple fibers with a length of 35mm to 45mm. The cotton is combed cotton with a specification of approximately 1.5D and a length of 29mm to 33mm. The finished yarn is a 60S single yarn with a twist coefficient of 320 to 360 and a strength of not less than 12cN / tex.

[0034] The wool composite layer has a higher proportion of mulberry silk in the warp yarns than wool. This design aims to enhance the overall smoothness and drape of the fabric through the high proportion of mulberry silk fibers. Wool fibers, as the main provider of warmth, with a ratio of 30% to 40% combined with the fluffy structure of the middle layer, already provide a warming effect superior to pure wool fabrics.

[0035] The wool composite layer weft yarn is a blended single yarn of wool, silk, cotton, and nylon (PA6). Wool accounts for 40% to 45%, silk 25% to 30%, cotton 15% to 20%, and nylon 5% to 8%. The nylon fiber uses semi-dull cut staple fibers of approximately 2.0D, with a length of 38mm to 45mm. The finished yarn specification is 60S single yarn, with a twist coefficient of 310 to 350, a strength of not less than 11.5cN / tex, and an elastic recovery rate of not less than 35%. The addition of nylon fiber is mainly due to the significant tension and friction experienced by the weft yarn during interlacing. The high strength and abrasion resistance of a small amount of nylon can significantly improve the durability of the weft yarn, thereby enhancing the overall lifespan of the fabric.

[0036] In this wool composite layer, the warp yarns are primarily made of mulberry silk, while the weft yarns incorporate nylon. This differentiated warp and weft design gives the composite layer better smoothness in the warp direction (dominated by mulberry silk) and better mechanical strength in the weft direction (reinforced by nylon). The combination of warp smoothness and weft strength gives the fabric both good drape and sufficient tensile strength when worn.

[0037] The reasons for choosing PA6 over PA66 are as follows: PA6 has a softer feel and better resilience, which matches the soft texture of silk and wool fabrics better. PA6 has a high dye absorption rate and good color fastness. Both silk and wool require excellent dyeing properties, and PA6 can ensure that the finished product has bright colors and a high degree of matching with the luster of silk. In contrast, PA66 is more difficult to dye and more expensive, making it less cost-effective than PA6 in composite fabrics. The proportion of nylon added needs to be strictly controlled. A ratio of 5% to 8% satisfies the requirements for durability while avoiding excessive amounts that would cause the fabric to stiffen.

[0038] The outer layer warp yarns are a blend of wool, silk, and cotton, consisting of 35% to 45% wool, 15% to 25% silk, and 35% to 45% cotton. The outer layer silk uses 20D to 30D semi-dull filaments, unlike the cut short fibers used in the inner layer and wool composite layer. The smooth, continuous surface of the long filament silk fibers, without the fuzz of short-fiber yarns, provides better luster and surface smoothness, giving the fabric a silky sheen similar to silk.

[0039] The wool is made from 16μm to 18μm ultrafine wool cut short fibers, with a length of 35mm to 45mm. The cotton is combed cotton, with a specification of approximately 1.5D and a length of 29mm to 33mm. The finished yarn is a 60S / 2 double-ply yarn with a twist coefficient of 290 to 330, a strength of not less than 13cN / tex, and a luster of not less than 85%. The double-ply structure makes the surface of the outer layer yarn smoother and more abrasion-resistant. At the same time, the double twist creates a fine spiral texture on the yarn surface, giving the fabric a unique texture and luster.

[0040] The outer layer has a lower wool content (35% to 45%) than pure wool fabrics, but combined with the wool fibers in the wool composite layer, the overall wool content of the fabric is sufficient to provide good warmth. The addition of silk filaments gives the outer layer a silky sheen, while cotton fibers ensure the fabric's shape retention and wrinkle resistance. The combination of these three fibers avoids the itchiness of pure wool fabrics and the wrinkling tendency of pure silk fabrics.

[0041] Based on the above embodiments, the silk-wool composite fabric of the present invention is woven in one piece using a multi-axis, multi-heald loom. The loom is equipped with three independent warp systems, corresponding to the outer layer warp, the wool composite layer warp, and the inner layer warp, respectively. Each of the three warp systems is equipped with an independent warp beam and tension control system, independently controlling the warp feed speed and warp tension of each layer. Because the warp specifications of the outer layer, wool composite layer, and inner layer are different (60S / 2 double-ply, 60S single-ply, and 40S / 2 double-ply, respectively), and their float-sink ratios with the weft yarns differ during weaving, the length of warp yarn consumed per unit length of fabric varies. Therefore, using independent warp beams and tension control is a necessary condition to ensure smooth weaving and uniform fabric quality.

[0042] Specific weaving parameters are determined based on fabric specifications. Loom speed is determined according to yarn specifications and fabric structure, generally between 200 and 400 revolutions per minute. The tension of the three warp systems is set as follows: 5 to 10 grams per yarn for the outer layer warp, 10 to 15 grams per yarn for the wool composite layer warp, and 8 to 12 grams per yarn for the inner layer warp. The outer layer warp tension is relatively low to accommodate its longer float length structure; the wool composite layer warp tension is slightly higher to ensure the structural stability of the intermediate layer.

[0043] The following rules apply during interweaving: the outer layer warp yarns float on the surface of the fabric, the inner layer warp yarns sink to the bottom layer of the fabric, and the wool composite layer warp yarns are interwoven between the outer layer and the inner layer.

[0044] The specific float-to-sink ratio is designed as follows: the outer layer warp yarns and the wool composite layer weft yarns interweave with a 3-over-1-under float-to-sink ratio. That is, out of every four weft yarns, three outer layer warp yarns float above the weft yarns, and one sinks below them. This 3-over-1-under interweaving method creates longer floats on the fabric surface. The longer the floats, the larger the reflective area of ​​the yarns, and the better the fabric's luster. At the same time, the longer floats reduce the surface friction coefficient, making the hand feel smoother.

[0045] The wool composite layer warp and weft yarns interweave at a 2:2 ratio, creating a relatively balanced plain weave structure. This 2:2 interweaving structure gives the wool composite layer good structural stability and a sense of bulkiness in the thickness direction, helping to maintain a still air layer and enhance warmth. Simultaneously, during the interweaving process, the wool composite layer warp yarns connect with the outer and inner layer warp yarns at selected interweaving points. This selective connection mechanism ensures the three layers are tightly linked in the thickness direction, guaranteeing the fabric's integrity.

[0046] The inner lining warp yarns and wool composite layer weft yarns are interwoven in a 1:3 ratio, meaning that out of every four weft yarns, one inner lining warp yarn floats above the weft yarns, while three sink below them. This 1:3 interweaving method ensures that the inner lining warp yarns are primarily submerged on the bottom surface of the fabric, creating a smooth inner surface. This helps reduce friction between the inner surface and the skin, improving comfort when worn close to the skin.

[0047] The combination of these three float / sink ratios allows the three warp yarn systems, after interlacing with the same set of weft yarns, to form a continuous transition structure from the outer surface to the inner surface in the fabric thickness direction. The floated long threads of the outer layer warp yarns create a smooth appearance, while the sinking structure of the inner layer warp yarns creates a flat inner surface. The balanced interlacing of the wool composite layer warp yarns provides intermediate connection and insulation space. The three warp yarns, with different float / sink patterns, interlace in the same weaving process, forming an inseparable, integrated three-layer composite fabric in one piece.

[0048] Experimental Example 1 To verify the technical effectiveness of this invention, commercially available mainstream pure wool fabrics were selected as the control group, and the fabric of this invention was used as the experimental group. Multiple performance tests were conducted according to textile industry standards. The test items, standards, and results for each group are as follows: Thermal performance test: The thermal resistance of the fabric was tested according to GB / T 11048-2018 standard (Determination of thermal and moisture resistance of textiles under steady-state conditions for physiological comfort). The thermal resistance of the experimental group was 0.38 Kelvin per watt, and that of the control group was 0.32 Kelvin per watt. The thermal resistance of the fabric of this invention is 18.75% higher than that of pure wool fabric, thus enhancing its heat retention and warmth preservation capabilities. The reason for this is that the three-layer structure of the fabric of this invention forms multiple air layers in the thickness direction. There are tiny gaps between the inner layer and the wool composite layer, and between the wool composite layer and the outer layer, effectively increasing the number of static air layers.

[0049] Abrasion resistance test: Following GB / T 21196.2-2007 standard (Determination of abrasion resistance of fabrics using the Martindale method), the Martindale abrasion tester was used to test the number of abrasion cycles on the samples. The experimental group reached 25,000 abrasion cycles, while the control group reached 15,000 cycles. The abrasion resistance of the fabric of this invention is 66.67% higher than that of pure wool fabric, and the fabric is more resilient. The improved abrasion resistance is mainly due to three aspects: the double-ply yarn structure of the outer layer improves surface abrasion resistance; the addition of nylon fibers in the weft yarn of the wool composite layer enhances the mechanical strength of the middle layer; and the integrated weaving structure avoids interlayer slippage and disperses surface frictional stress.

[0050] Anti-pilling performance test: The fabric was rated for pilling resistance according to GB / T 4802.1-2008 standard (Determination of Pilling Performance of Textile Fabrics - Circular Locus Method). The rating standard ranged from 1 to 5, with 1 being the worst and 5 the best. The experimental group received a pilling rating of 4 (slight pilling, negligible), while the control group received ratings of 2 to 3 (significant pilling). The anti-pilling performance of the fabric of this invention is approximately two levels higher than that of pure wool fabric. The improved pilling performance is due to: the smooth surface of silk fibers without scales reduces friction and entanglement between fibers; and the outer layer uses a double-ply yarn structure with fewer fiber ends on the yarn surface, reducing the fiber source of pilling.

[0051] Dimensional change rate test after washing: The dimensional change of the fabric after a standard washing procedure was tested according to relevant standards. The experimental group showed a warp dimensional change rate of -0.8% and a weft dimensional change rate of -0.6%; the control group showed a warp dimensional change rate of -3.0% and a weft dimensional change rate of -2.5%. The fabric of this invention shows significantly less dimensional change after washing than pure wool fabric, with a lower shrinkage rate and better dimensional stability.

[0052] Snagging resistance test: The fabric's snag resistance was tested according to GB / T 11047.3-2024 standard. The rating system ranged from 1 to 5, with 1 being the worst and 5 the best. The experimental group received a snag resistance rating of 4, while the control group received ratings of 2 to 3. The fabric of this invention has a smoother surface, tighter fiber bonding, and is less prone to being snagged by sharp objects, exhibiting superior snag resistance compared to pure wool fabric. The results are summarized in the table below:

[0053] Experiment Example 2 To evaluate the skin-friendly comfort of the fabric during actual wear, 100 testers aged 18 to 65 were selected. Under the same environmental conditions, they wore garments made of the three-layer composite fabric of this invention and commercially available pure wool fabric, respectively. The test was conducted using a single-blind method, with the testers unaware of the type of fabric they were wearing. Each tester wore garments made of one of the two fabrics for 4 hours, and then subjectively rated and provided feedback on the fabric's skin-friendliness and itchiness.

[0054] The evaluation results showed that 82 testers found the fabric of this invention to be more skin-friendly and softer than pure wool fabric, with a significant reduction in skin irritation and a marked improvement in comfort when worn close to the skin. 18 testers felt there was little difference between the two. No testers found the fabric of this invention to be more irritating than pure wool fabric. This result indicates that the invention, through its three-layer structural design, with an inner layer made of a blend of mulberry silk and cotton, effectively isolates wool fibers from direct contact with the skin, solving the problem of traditional pure wool fabrics causing irritation and being unsuitable for direct contact with the skin.

[0055] The subjective evaluation involved test participants aged 18-25, 26-40, and 41-65, comprising 48 men and 52 women. The evaluation results across age groups and genders were relatively consistent, and no significant differences were found in the skin-friendliness evaluations of the fabric of this invention among specific populations, indicating that the fabric of this invention has good skin-friendliness and adaptability for wearers of different ages and genders.

[0056] Based on the above test results and evaluation data, the silk-wool composite fabric of this invention outperforms commercially available pure wool fabrics in multiple performance indicators. It achieves significant improvements in warmth retention, abrasion resistance, pilling resistance, dimensional stability, snag resistance, and wearing comfort, effectively solving long-standing technical problems of traditional pure wool fabrics such as itchiness, lack of skin-friendliness, pilling susceptibility, and shrinkage and deformation after washing.

[0057] The fabric of this invention possesses the following comprehensive characteristics: it is soft and silky, with a delicate feel, excellent elasticity, and good drape; it has excellent heat retention and insulation properties; the fabric is tough and wear-resistant, not prone to pilling or deformation; and it maintains its dimensions after washing, without easily shrinking or deforming. This fabric is suitable for making winter innerwear, such as thermal underwear, base layers, shirts, and dresses, and can also be used to make scarves, shawls, hats, and other accessories, offering both comfort and a high-end feel.

[0058] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
