Description

Technical Field

[0001] The invention relates to the field of textile technology, in particular to a weaving method of a novel 3D three-dimensional checkered air layer dry warp knitted fabric. Background Art

[0002] This fabric is woven on the market using 5 knitting devices and tissues. The first, second and third knitting materials are fully drafted raw materials, the fourth knitting material is network yarn, and the fifth knitting material is elastic fiber. Currently, there are not many applications for 5-knitting devices on the market. The equipment is small and the production capacity is low. The use of Karl Mayer warp knitting double needle bed knitting equipment can achieve the weaving of 5 guide bars, but because the machine itself is designed as a multi-guide bar double-sided fabric equipment, the production capacity of single-sided fabrics will be reduced by half at the same speed, and the cost will increase; and the warp knitting double needle bed knitting equipment can achieve the weaving of 5 guide bars. Due to the special machine structure, when using 5 combs to weave this product, the swing amplitude of the 1st to 5th combs is large, which can easily lead to instability of the machine equipment, an increase in defects, uneven weaving surface, or even failure to weave successfully, and the risk of increased defective rate. Based on these risks, this method uses a composite elasticized comb of nylon all-polyamide network yarn and polyurethane elastic fiber in the fourth weaving structure to achieve 4 combs using ordinary 4-comb Karl Mayer warp knitting equipment for weaving, so as to achieve high speed, high yield, reduce costs and increase market share advantages. Summary of the Invention

[0003] The purpose of the present invention is to provide a novel weaving method for 3D three-dimensional checkered air layer dry warp knitted fabric, which can achieve rapid production and high production capacity, achieve high profit margin, reduce costs and realize mass production.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for weaving a novel 3D checkered air-layer dry warp-knitted fabric, comprising a fabric body, wherein the warp-knitted fabric is woven from first, second, third, and fourth materials, wherein the first, second, and third woven materials are combined through varying length-short slidable weaving conditions to form a 3D rectangular checkered pattern on the fabric surface, and the fourth material has a plain warp weave structure. Furthermore, the first, second, and third woven materials are fully drawn nylon all-polyamide fiber raw materials, and the fourth woven raw material is an elastic covering material formed by intertwining 71% nylon all-polyamide network yarn and 29% polyurethane elastic fiber in a processing ratio.

[0005] Furthermore, the density of the fourth braided material is 51 to 111 deniers, and the density of the first, second and third braided materials is 30 to 70 deniers.

[0006] Furthermore, it is knitted by a single needle bed 32-needle four-comb warp knitting machine equipped with GB1 first knitting tissue, GB2 second knitting tissue, GB3 third knitting tissue and GB4 fourth knitting tissue.

[0007] Furthermore, the inlay yarn numbers of the first weaving tissue of GB1 are (1-2, 3-2) / (0-1, 4-3)*3 / (1-2, 3-2) / (0-1, 4-3)*3 / / ; the inlay yarn numbers of the second weaving tissue of GB2 are (1-2, 3-2) / (0-1, 4-3)*3 / (1-2, 3-2)*4 / / ; the inlay yarn numbers of the third weaving tissue of GB3 are (1-2, 3-2)*5 / (0-1, 4-3)*3 / / ; the inlay yarn numbers of the fourth weaving tissue of GB4 are 1-0, 2-3 / / .

[0008] Furthermore, the warp drawing method of the first braided structure GB1 is to thread 3 fully-drawn raw materials of all-polyamide fibers and then thread 9 yarns without drawing; the warp drawing method of the second braided structure GB2 is to thread 3 fully-drawn raw materials of all-polyamide fibers and then thread 9 yarns without drawing; the warp drawing method of the third braided structure GB3 is to thread 3 fully-drawn raw materials of all-polyamide fibers and then thread 9 yarns without drawing; the warp drawing method of the fourth braided structure GB4 is full threading.

[0009] Furthermore, the weaving method also includes post-finishing, which is performed by adding a superconducting additive during the bath dyeing process and then drying the fabric in an open width manner.

[0010] The beneficial effects of the present invention are as follows: the method of the present invention can realize batch production with high speed, high production capacity and high efficiency through the improvement of raw materials and processes, and at the same time can achieve high profit margin and reduce costs, and can also ensure that the properties and physical indicators of the fabrics woven by 4 weaving machines and the appearance of the fabrics produced by 5 weaving machines are consistent through comprehensive testing. The 3D three-dimensional checkered pattern formed by weaving can allow moisture or sweat to enter the outer side from the criss-cross nylon groove surface, and the outer side will not enter the nylon surface, thereby achieving a one-way moisture conduction effect.

[0012] Figure 2 This is a front view of the fabric of the present invention;

[0013] Figure 3 The figure shows the reverse side of the fabric of the present invention.

[0014] Among them: 1. 3D rectangular checkered pattern, 2. bottom surface. DETAILED DESCRIPTION

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] See also Figures 1 to 3 The present invention provides, in one embodiment, a method for weaving a novel 3D checkered air-layer dry warp-knitted fabric. The method comprises a fabric base, wherein the warp-knitted fabric is woven from first, second, third, and fourth materials. The first, second, and third materials are knitted using varying lengths of skewered weave conditions to form a 3D rectangular checkered pattern 1 on the fabric surface. The fourth material has a plain weave structure. The first, second, and third knitting machines utilize different threading methods and varying lengths of cross-stitched weaves to create a pattern on the fabric surface. This pattern is then combined with a fourth knitting machine comprising a composite yarn of network yarn and elastic fiber to form a regular 3D checkered pattern on the fabric surface. The fabric surface has a 3D rectangular checkered pattern 1, while the bottom surface 2 is a dense and elastic plain weave. The squares formed in the finished fabric are slightly visible on the base. The woven material has a full matte finish, creating a pleasant visual effect and a comfortable, natural, and calming feeling. The final fabric, when woven into clothing, has a matte finish, enhancing the sense of harmony with nature in the autumn and winter outdoors, achieving a perfect fusion of clothing and nature. High production efficiency, high production capacity, and low costs make this fabric highly competitive in the market. The fourth material's plain weave, combined with varying lengths of weaving in the first, second, and third weaves, creates a 3D rectangular checkered pattern on the surface (1) and a dense, elastic plain weave on the bottom (2). The resulting 3D, regular, and compact rectangular pattern allows moisture or sweat to enter the outer surface through the crisscrossing nylon grooves, preventing it from entering the nylon surface, achieving a one-way moisture conduction effect. This unique rectangular structure promotes and accelerates the transfer of moisture and heat from the inner layer to the outer layer. The larger the mesh or gaps in the inner layer, the smaller the mesh in the outer layer, accelerating the transfer of sweat from the inner layer to the outer layer, allowing it to evaporate and dry quickly on the outer layer. The woven material features a full matte finish, resulting in a matte finish when made into clothing, enhancing the sense of harmony with nature in the autumn and winter outdoors, achieving a perfect fusion of clothing and nature. High production efficiency, high production capacity, and low costs make this fabric highly competitive in the market.

[0017] Please continue reading Figures 1 to 3As shown in one embodiment of the present invention, the first, second, and third braided materials are made of fully drawn nylon all-polyamide fiber. The fourth braided material is an elastic covering material made by twisting 71% nylon all-polyamide network yarn and 29% polyurethane elastic fiber in a ratio of 2. The inner layer is made of a nylon composite material with high elasticity, which is soft to the touch, wear-resistant, and has good elastic recovery. The 3D concave and convex pattern quickly conducts sweat to keep the body dry while forming an air layer to keep the body warm and prevent hypothermia. The use of nylon all-polyamide fiber fully-drawn raw materials and polyurethane elastic fiber can improve the dryness and comfort of the fabric, and the network yarn and elastic fiber are entangled together through spinning equipment according to the processing ratio of 71% nylon all-polyamide fiber fully-drawn raw materials and 29% polyurethane elastic fiber to form a new elastic coating raw material. The new elastic coating raw material has both the appearance of network yarn and the characteristics of elastic fiber, and is produced using a high-capacity single-needle bed 32-needle four-comb warp knitting machine with fast speed, high production capacity and high efficiency, which can achieve high profit margins, reduce costs and realize mass production. It can also ensure that the properties and physical indicators of the fabrics woven by 4 combs are consistent with the appearance of the fabrics produced by 5-comb weaving equipment, and the comprehensive test ensures consistency. The production capacity can reach 290kg / 24 hours, which is 2.6 times higher than the production capacity of the 5-comb equipment. The product manufacturing cost is greatly reduced, creating huge market competitiveness and expanding market share.

[0018] Please continue reading Figures 1 to 3 As shown, in one embodiment of the present invention, the density of the fourth braided material is 51 to 111 deniers, and the densities of the first, second, and third braided materials are 30 to 70 deniers. Preferably, the densities of the first, second, and third braided materials are 40 deniers, and the density of the fourth braided material is 50 deniers.

[0019] Please continue reading Figures 1 to 3 As shown, in one embodiment of the present invention, it is woven by a single needle bed 32-needle four-comb warp knitting machine equipped with GB1 first knitting structure, GB2 second knitting structure, GB3 third knitting structure and GB4 fourth knitting structure.

[0020] Please continue reading Figures 1 to 3As shown, in one embodiment of the present invention, the inlay yarn numbers of the first braiding structure GB1 are (1-2, 3-2) / (0-1, 4-3)*3 / (1-2, 3-2) / (0-1, 4-3)*3 / / ; the inlay yarn numbers of the second braiding structure GB2 are (1-2, 3-2) / (0-1, 4-3)*3 / (1-2, 3-2)*4 / / ; the inlay yarn numbers of the third braiding structure GB3 are (1-2, 3-2)*5 / (0-1, 4-3)*3 / / ; and the inlay yarn numbers of the fourth braiding structure GB4 are 1-0, 2-3 / / . "(0-1, 4-3)*3" represents that the (0-1, 4-3) pattern is repeated three times, and the same applies to the following.

[0021] Please continue reading Figures 1 to 3 As shown, in one embodiment of the present invention, the warp drawing method of the first braided structure GB1 is to draw through 3 fully-drawn raw materials of all-polyamide fibers and then draw through 9 yarns; the warp drawing method of the second braided structure GB2 is to draw through 3 fully-drawn raw materials of all-polyamide fibers and then draw through 9 yarns; the warp drawing method of the third braided structure GB3 is to draw through 3 fully-drawn raw materials of all-polyamide fibers and then draw through 9 yarns; the warp drawing method of the fourth braided structure GB4 is full drawing.

[0022] Please continue reading Figures 1 to 3 As shown, in one embodiment of the present invention, the weaving method further includes post-finishing, which is performed by adding a superconducting additive during the bath dyeing process and then drying the fabric in open width. A hydrophobic finishing agent is added to the fabric during the dyeing process, which quickly conducts sweat to the surface of the garment for rapid evaporation, keeping the body dry. The 3D checkered pattern forms a 1mm thick air barrier when in contact with the skin, isolating the fabric from external cold air, preventing rapid hypothermia and providing warmth. The post-finishing also enhances the fabric's elasticity, crispness, good resilience, breathability, and dryness, maintaining body temperature balance.

[0023] The comprehensive moisture absorption performance test of the fabric also found that this fabric can achieve quick evaporation and dry, and has excellent performance in moisture absorption and quick drying to keep the body dry.

[0024] The above description is only a preferred embodiment of the present invention and should not be understood as limiting the present application. All equivalent changes and modifications made within the scope of the patent application of the present invention should fall within the scope of the present invention.
