Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically to a shock-absorbing and compression-resistant three-dimensional fabric and its production method. Background Technology

[0002] With the expansion of clothing applications, the demand for clothing fabrics has become increasingly functional. In outdoor sports, such as running, skiing, and some extreme sports, there is a need for enhanced protection of specific parts of the wearer's body, such as the head, feet, shoulders, elbows, and knees, to reduce impact and injury. Therefore, the corresponding clothing needs to have good elasticity and compression resistance, which in turn creates a significant demand for clothing fabrics with shock absorption and compression resistance.

[0003] However, because textile and apparel fabrics are flexible materials, most garment fabrics do not possess significant impact resistance, shock absorption, or compression resistance when subjected to external forces. The only ways to improve their protection against impact and pressure are to use multiple layers of fabric overlapped and sewn together during garment manufacturing to increase thickness, or to combine them with rigid materials (such as metals or hard plastics). However, using multiple layers of fabric overlapped and sewn together results in excessive garment thickness, affecting the wearing experience. Furthermore, this method primarily improves the garment's abrasion resistance, offering very limited shock absorption and compression resistance. Conversely, using rigid materials increases the rigidity of the corresponding areas and reduces the fabric's softness, restricting movement and also negatively impacting the wearing experience.

[0004] Chinese patent CN202222813038.3 provides a pressure-resistant fabric by knitting a first and second pressure-resistant layer, and then filling the space between the first and second pressure-resistant layers with adhesive resin. While this method can improve the pressure resistance of the fabric, the production process of filling the two layers with adhesive resin increases the production steps and complexity. In addition, this production process requires processing the fabrics into knitted fabrics before composite processing, resulting in high material and production costs, making it difficult to promote as a fabric for ordinary clothing. Summary of the Invention

[0005] To address the technical problem that existing clothing fabrics with shock-absorbing and compression-resistant functions require the combination of materials other than woven fabrics, resulting in high production costs and complex processes, this invention provides a shock-absorbing and compression-resistant three-dimensional structure fabric and its production method. Through a production process of layered weaving with multiple different materials, the three-dimensional structure fabric forms a compression-resistant three-dimensional structure with a certain thickness and stable structure, possessing excellent shock-absorbing and compression-resistant performance. The production process is simple and easy to mass-produce and promote.

[0006] In a first aspect, the present invention provides a shock-absorbing and compression-resistant three-dimensional structure fabric. The three-dimensional structure fabric is a multi-layered jacquard fabric, including an independently woven and interconnected outer fabric, a middle fabric, and an inner fabric. The outer fabric and the middle fabric are respectively interwoven with warp and weft yarns to form a honeycomb structure, and the inner fabric is interwoven with warp and weft yarns to form a plain weave structure.

[0007] Furthermore, the warp yarns of the outer layer, middle layer, and inner layer are of the same material and shape.

[0008] Furthermore, the weight of three-dimensional woven fabrics is 250-400 g / m². 2 .

[0009] Secondly, the present invention provides a method for producing the above-mentioned three-dimensional structured fabric, the steps of which include: (1) Spinning: using a single material to produce general warp yarn through any spinning method; using three different materials to produce surface weft yarn, middle weft yarn and inner weft yarn through three different spinning methods respectively; (2) Weaving: Weaving is carried out using machine weaving technology. The general warp yarns are divided into three groups, which are interwoven with the surface weft yarns to make the surface fabric, interwoven with the middle weft yarns to make the middle fabric, and interwoven with the inner weft yarns to make the inner fabric. The surface fabric, middle fabric and inner fabric are connected to make the composite fabric. (3) Dyeing and finishing: the combined fabric is subjected to back sewing, pretreatment, bleaching, dyeing and finishing to obtain a three-dimensional structure fabric.

[0010] Preferably, the general warp yarn is pure cotton yarn.

[0011] Furthermore, the outer weft yarn is Siro-spun yarn, the middle weft yarn is high-elastic filament, and the inner weft yarn is spandex core-spun yarn. Among them, the Siro-spun yarn is soft to the touch, wear-resistant, and breathable, which can bring a good feel to the surface of the three-dimensional structured fabric; the high-elastic filament and spandex core-spun yarn have good shrinkage properties, which can increase the dimensional stability and compression resistance of the fabric.

[0012] Preferably, the middle layer weft yarn is T150D high-elastic polyester filament.

[0013] Furthermore, in step (3), the dyeing process is to use a dyeing overflow cylinder for tension-free overflow dyeing. The combined fabric fully shrinks in the tension-free state of the dyeing overflow cylinder. The weft yarns of the surface fabric and the middle layer fabric with honeycomb structure shrink, increasing the three-dimensional effect of the fabric. After setting, the shrinkage dimensions of the surface fabric, the middle layer fabric and the inner layer fabric are solidified, and the compression resistance of the fabric is stabilized. When subjected to external pressure, the deformation buffers the pressure, thereby improving the shock absorption performance.

[0014] The beneficial effects of this invention are as follows: This invention employs a multi-layered weaving process using various materials to produce surface, middle, and inner fabrics, which are then combined. The surface and middle fabrics have a honeycomb structure, while the inner fabric possesses excellent elasticity. Through the shrinkage and shaping of each layer during the dyeing and finishing process, the three-dimensional structure of the fabric is greatly enhanced. The resulting three-dimensional fabric, after dyeing and finishing, forms a compression-resistant three-dimensional structure with a certain thickness, stable structure, and elastic properties. When subjected to external pressure, it can produce longitudinal and transverse stretching deformation, exhibiting excellent shock absorption and compression resistance.

[0015] This invention uses existing textile materials and a machine-woven method to produce three-dimensional structured fabrics. The raw materials do not contain any materials other than textile materials. It can be directly produced using existing textile equipment and materials. The production process is simple, with low material and production costs, and is easy to mass-produce and promote. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0024] Example 1 A shock-absorbing and compression-resistant three-dimensional woven fabric, comprising a multi-layered jacquard fabric, including an independently woven but interconnected outer layer, a middle layer, and an inner layer. The outer and middle layers are woven with warp and weft yarns to form a honeycomb weave, while the inner layer is woven with warp and weft yarns to form a plain weave. The warp yarns of the outer, middle, and inner layers are of the same material and shape. The production steps are as follows: (1) Spinning: 100% pure cotton fiber is processed by ring spinning to produce general warp yarn. The specific steps include opening, carding, drawing, roving, spinning, and winding. The general warp yarn count is 40S pure cotton. The surface weft yarn is made from 100% Lyocell fiber through Siro spinning process. The specific steps include opening, carding, drawing, roving, Siro spinning, and winding. The resulting surface weft yarn has a count of 30S. T150D high-elastic polyester filament was prepared by melt spinning process and used as the intermediate layer weft yarn; The inner weft yarn is made by core-spun yarn of pure cotton fiber and spandex fiber. The specific steps include opening, carding, drawing, roving, core-spun yarn, and winding. The inner weft yarn has a count of 40S pure cotton and 70D core-spun yarn.

[0025] (2) Weaving: Using machine weaving technology, the general warp yarns are divided into three groups, which are interwoven with the surface weft yarns to form the surface fabric, interwoven with the middle weft yarns to form the middle fabric, and interwoven with the inner weft yarns to form the inner fabric. The surface fabric, middle fabric, and inner fabric are then connected to form a composite fabric. The specific process flow is as follows: (i) Warping: The warp yarn used in the fabric is cotton 40s yarn. The production process is to warp 14 beams in total, with 680 warp ends per beam, for a total of 9520 warp ends. The warping speed is 550m / min and the tension bar spacing is 4mm. (ii) Sizing: The 14 warp beams are divided into two groups and fed into the front and rear sizing pots according to the predetermined yarn feeding channels, where they are evenly sized. The sizing process is as follows: 87.5 kg of microwave polymerized sizing agent and 20 kg of PVA are used, with a sizing volume of 0.8 m³. 3The sizing speed is 70 m / min, the viscosity is 7.5~8 s, the sizing rate is 14%~16%, and the moisture regain is 7~9%. After sizing, the yarns are grouped and dried in a drying oven until nearly dry on a cylinder. The pre-drying cylinder temperature is 120℃, and the main drying cylinder temperature is 100℃, ensuring uniform drying. The dried sheet yarns are then waxed in a wax bath, and then separated layer by layer by a skein to form individual sized yarns. These yarns are then evenly arranged by a reed comb and wound onto the warp beam according to the width of the warp beam discs, ensuring they are not loose or collapsed. The distance between the warp beam discs is 1805 mm. (iii) Reed threading: After the warp beam is moved to the reed threading machine, the sized warp yarns are threaded into the stop warp, heddle, and reed according to the fabric structure order, avoiding missed threading, incorrect threading, and twisting. Then the yarn is threaded into the reed. The threading process is 4 yarns / reed for the selvage and 3 yarns / reed for the body. The threaded yarn is knotted outside the reed to prevent it from coming loose. The warp threading process is as follows: the stop warp pieces are threaded in the order of 1, 2, 3, 4, 5, 6; the heddle wires of the fabric body are threaded in the order of the heddle frame number: 1, 2, 11, 3, 4, 12, 5, 6, 11, 7, 8, 12, 13, 10, 11, 7, 9, 12, 5, 6, 11, 3, 4, 12, for a cycle of 385 times; the selvage heddle wires are threaded in the order of 14, 14, 15, 15, for a cycle of 35 times each; the reeds are 4 per selvage and 3 per fabric body, using reed size 88.6# × 3810mm; (iv) Weaving: Weaving is carried out on the loom in accordance with the standard operating procedures for weaving. Example 1 is a small jacquard structure. The heald frame of the fabric body is controlled according to the heald sequence of the weave diagram. The warp yarns are divided into three groups and interwoven with the three groups of weft yarns respectively. The selvage heald frame is 2 / 2 structure. The process parameters of the loom are: back beam height is 75mm, opening time is 310 degrees, machine tension is 2300N, medium height weave opening improves the clarity of the three-layer weave opening, late opening extends the flight time and reduces the number of weft breaks; the three types of weft yarns are introduced into the weave opening in a 1:1:1 ratio, and the weft density on the loom is 120 threads / inch to obtain the composite fabric.

[0026] (3) Dyeing and finishing: the combined fabric is subjected to backstitching, pretreatment, bleaching, dyeing and finishing. The dyeing process is tension-free overflow dyeing using a dyeing overflow tank to obtain a three-dimensional structure fabric. The finished width of the three-dimensional structure fabric is 55cm and the weight is 392g / m². 2 The thickness is 3.10mm.

[0027] The weave diagram of the surface fabric in Example 1 is shown below. Figure 1 As shown, blank squares represent weft weave points, and black squares represent warp weave points, demonstrating that the surface fabric forms a honeycomb structure through the interweaving of warp and weft yarns.

[0028] The performance of the three-dimensional woven fabric prepared in Example 1 was tested using a YG141 fabric thickness gauge. The pre-applied weight on the surface of the three-dimensional woven fabric was gradually increased, and the fabric thickness under this pressure was measured. Then, the pressure was gradually decreased, and the corresponding thickness was measured again. The test area was 10 cm². 2 The obtained test data is shown in Table 1. The performance curves plotted based on the data in Table 1 are shown below. Figure 6 As shown.

[0029] Table 1 Performance test data of three-dimensional fabric Test order Fabric thickness (mm) Preset weight 1 3.018 300g 2 2.925 500g 3 2.847 700g 4 2.778 900g 5 2.728 1100g 6 2.69 1300g 7 2.716 1100g 8 2.758 900g 9 2.811 700g 10 2.871 500g 11 2.941 300g As can be seen, the measured fabric thickness of the three-dimensional structure fabric in Example 1 gradually decreased as the pressure gradually increased; while the measured fabric thickness gradually recovered as the pressure gradually decreased. When the pressure was reduced to the initial pre-fabricated weight (300g), the three-dimensional structure fabric recovered to 97.4% of its original thickness, proving that the three-dimensional structure fabric prepared in Example 1 has good compression resistance and excellent shock absorption.
