Description

Technical Field

[0001] This invention pertains to a multifunctional fabric with high breathability and symmetry in the field of warp-knitted fabrics, specifically involving a quantum breathable fabric containing regenerated Juncao fibers. Background Technology Existing quick-drying and breathable fabrics are mostly made of pure synthetic fibers (such as polyester and nylon) or blended yarns, which have problems such as poor natural antibacterial properties, insufficient environmental friendliness, unbalanced moisture absorption and quick-drying properties, and unstable elastic recovery in the transverse and longitudinal directions. Because synthetic fiber fabrics are prone to bacterial growth, they affect wearing comfort. The synthetic fibers used in the spinning of existing traditional fabrics rely on petroleum-based raw materials and are non-degradable. Moreover, most quick-drying fabrics have poor moisture absorption, which leads to sweat retention. Due to the inherent defects of warp-knitted fabrics, the use of spandex single-component knitting can easily lead to fabric deformation after long-term use. In order to improve the breathability of existing fabrics, they are usually treated with fluorinated finishing agents, but the surface area of ​​chemical fibers is not high, and the treatment effect is not ideal. Summary of the Invention In view of the shortcomings of the existing technology, the purpose of this invention is to provide a quantum breathable fabric containing regenerated Juncao fiber and a weaving method that can overcome the above-mentioned shortcomings.

[0002] The technical solution adopted by this invention to solve its technical problem is: a quantum breathable fabric containing regenerated Juncao fiber. The key is that the quick-drying breathable fabric includes a fabric body, which is woven from four yarns (GB1, GB2, GB3, and GB4) through a warp knitting process. GB1, GB2, GB3, and GB4 are respectively threaded through the first, second, third, and fourth yarns. The yarn threading numbers and threading methods of GB1, GB2, GB3, and GB4 are as follows: GB1: 1-0 / 2-3 / 4-5 / 3-2 / / 1 thread 1 empty; GB2: 4-5 / 3-2 / 1-0 / 2-3 / / 1 empty 1 thread; GB3: 1-0 / 2-3 / 4-5 / 3-2 / / 1 thread 1 empty; GB4: 4-5 / 3-2 / 1-0 / 2-3 / / 1 thread 1 empty. The structure is 1 open and 1 through; GB1, GB2, GB3, and GB4 are all warp-forged structures; the first yarn is a regenerated straw fiber yarn, and the second yarn is a nylon yarn; the weight ratio of the third and fourth yarns is 1:0.8 to 1.4 spandex yarn, and GB1 and GB2 are interwoven with GB2 at stitches 1 to 2 and 4 to 5 of each GB1; after the fabric body is woven, it is treated by soaking in a solution of nano zinc oxide mixed with fluorine finishing agent, so that the surface of the yarn fibers of the fabric body has a continuous fluorocarbon film layer mixed with nano zinc oxide.

[0003] The coil height ratio of GB1, GB2, GB3, and GB4 is 1:1:1.2:0.8, and the tension control of GB1 and GB4 is 25±1 cN and 18±1 cN, respectively.

[0004] The ratio of the amount of material sent from GB1 to GB3 is 1:1.2±0.1.

[0005] The ratio of the amount of GB2 to GB4 sent is 1:1.0±0.1.

[0006] The first yarn is a 35D yarn, the second yarn is a 40D yarn, the third yarn is a 20D yarn, and the fourth yarn is a 25D yarn.

[0007] A method for weaving a quantum breathable fabric containing regenerated Juncao fiber includes the following steps: A warp knitting machine with four guide bars (GB1, GB2, GB3, and GB4). The yarn threading codes and yarn threading patterns of GB1, GB2, GB3, and GB4 are as follows: GB1: 1-0 / 2-3 / 4-5 / 3-2 / / Yarn threading pattern is 1 thread 1 empty; GB2: 4-5 / 3-2 / 1-0 / 2-3 / / Yarn threading pattern is 1 empty 1 thread; GB3: 1-0 / 2-3 / 4-5 / 3-2 / / Yarn threading pattern is 1 thread 1 empty; GB4: 4 -5 / 3-2 / 1-0 / 2-3 / / The yarn threading structure is 1 empty and 1 threaded; GB1, GB2, GB3, and GB4 thread the first yarn, the second yarn, the third yarn, and the fourth yarn, respectively. The first yarn is a Juncao regenerated fiber yarn. GB1 and GB2 are interwoven with GB2 at the 1st to 2nd and 4th to 5th needle positions of each GB1. The knitting actions of GB1 and GB2 are started and executed simultaneously. (ii) Quantum processing steps: After the fabric body is knitted, it is soaked in a solution of nano zinc oxide mixed fluorine finishing agent at 160°C for 40 to 50 seconds.

[0008] In the method described, the weight ratio of the first yarn to the second yarn is 1:1 to 1.2; the weight ratio of the third yarn to the fourth yarn is 1:0.8 to 1.4; the second yarn is nylon yarn; and the third and fourth yarns are both spandex yarns.

[0009] The method described uses a 40-needle warp knitting machine.

[0010] The method described herein has a coil height ratio of 1:1:1.2:0.8 for GB1, GB2, GB3, and GB4, and the tension controls for GB1 and GB4 are 25±1 cN and 18±1 cN, respectively.

[0011] The method described herein has a warp delivery ratio of GB1 to GB3 of 1:1.2±0.1 and a warp delivery ratio of GB2 to GB4 of 1:1.0±0.1.

[0012] The present invention relates to a quantum breathable fabric containing regenerated cellulose fibers and its weaving method. The fabric uses regenerated cellulose fibers as one of the yarns, combined with wear-resistant nylon and spandex yarns. It employs a double-symmetrical structure with identical padding yarns and interlacing, resulting in good breathability, low crimp, and a close ratio of transverse and longitudinal elastic recovery, as well as a high weaving speed. After weaving, the fabric is treated with a solution of nano-zinc oxide mixed with fluorine-based finishing agents. Due to the very high internal surface area of ​​the regenerated cellulose fiber yarns, the fabric develops unexpected hydrophobic, breathable, and self-cleaning properties, achieving high breathability, rapid drying, long-lasting elasticity, and natural antibacterial functions, thus possessing broad application prospects. Attached Figure Description Figure 1 This is a schematic diagram of the structure of the present invention.

[0013] Figure 2 This is a schematic diagram of the structure of the present invention. Detailed Implementation like Figures 1 to 2As shown, a quantum breathable fabric containing regenerated Juncao fiber is disclosed. The quick-drying breathable fabric includes a fabric body, which is woven from four yarns (GB1, GB2, GB3, and GB4) using a warp-knitting process. GB1, GB2, GB3, and GB4 are respectively threaded through the first, second, third, and fourth yarns. The threading numbers and threading methods of GB1, GB2, GB3, and GB4 are as follows: GB1: 1-0 / 2-3 / 4-5 / 3-2 / / 1 threaded, 1 empty; GB2: 4-5 / 3-2 / 1-0 / 2-3 / / 1 empty, 1 threaded; GB3: 1-0 / 2-3 / 4-5 / 3-2 / / The yarn threading structure is 1 thread, 1 gap; GB4: 4-5 / 3-2 / 1-0 / 2-3 / / The yarn threading structure is 1 gap, 1 thread; GB1, GB2, GB3, and GB4 are all warp-forged structures; the first yarn is regenerated straw fiber yarn, and the second yarn is nylon yarn; the weight ratio of the third and fourth yarns is 1:0.8 to 1.4 spandex yarn, and GB1 and GB2 interweave with GB2 at needle positions 1-2 and 4-5 of each GB1; after the fabric body is woven, it is treated with a solution of nano-zinc oxide mixed with fluorine finishing agent, resulting in a continuous fluorocarbon film layer mixed with nano-zinc oxide on the surface of the yarn fibers of the fabric body. GB1 and GB2 overlap at some needle positions. The aforementioned Juncao regenerated fiber yarn is a commercially available textile yarn, such as the product sold by Xinxiang Chemical Fiber Co., Ltd.; the aforementioned quantum breathable fabric containing Juncao regenerated fiber has a structure woven from four yarns: GB1, GB2, GB3, and GB4. GB1 and GB3 employ a mirrored yarn threading configuration, as do GB2 and GB4. Furthermore, GB1 and GB3 use a 1-thread-1-gap configuration, while GB2 and GB4 use a 1-gap-1-thread configuration, resulting in a symmetrical and balanced fabric overall and significantly reducing the edge curvature of the surface. The 1-thread-1-gap and 1-gap-1-thread configurations of GB1 and GB2 in this invention create an internal stress inclination in the fabric, overcoming the traditional limitation of open needles in warp-knitted fabrics where the formation of holes mainly depends on the warp-threading pattern of the guide bars. "Open needle" refers to the fact that during warp threading, some needles do not penetrate the yarn, creating gaps and thus increasing the fabric's breathability. Under ISO-9237 testing conditions, one embodiment of this fabric has an air permeability of 2850 L / m² / s.

[0014] like Figure 1As shown, GB1 and GB2 have a crossover stitch at positions 5-6 of the padding yarn number. In terms of yarn structure, this means that positions 1-2 and 4-5 of each GB1 stitch are interwoven with GB2 stitches. The interweaving of GB1 and GB2 constitutes the outer and inner fabric structure. The crossover stitch in the padding yarn number can improve the overall strength of the fabric and provide breathable mesh. GB3 and GB4 together constitute the weft insertion structure of the fabric, providing transverse and longitudinal elasticity.

[0015] The coil height ratio of GB1, GB2, GB3, and GB4 is 1:1:1.2:0.8. The tension control of GB1 and GB4 is 25±1 cN and 18±1 cN, respectively. By controlling the tension of GB1 and GB4, GB2 adapts to the tension control of GB1, and GB3 adapts to the tension control of GB4, thereby ensuring the overall tension control of the fabric and maintaining its flatness, resulting in better straightness of the fabric.

[0016] The ratio of the amount of material sent from GB1 to GB3 is 1:1.2±0.1.

[0017] The warp feed ratio of GB2 to GB4 is 1:1.0±0.1. The fabric of this invention can achieve the required loop height by controlling the warp feed and tension. Different loop heights can control the warp and weft elasticity recovery rates of the fabric. Since the warp and weft elasticity of fabrics obtained through warp knitting methods differ, under the padding yarn number of this fabric, the warp and weft elasticity recovery rates can be adjusted by controlling the loop heights of GB3 and GB4, thereby enabling the elasticity recovery rate of the fabric of this invention to reach 96% in the longitudinal direction and 90% in the transverse direction (GB / T 10655).

[0018] In four-comb warp-knitted fabrics, a symmetrical combination of 1-through-1-open and 1-open-1-through structures is used. Due to the reduced yarn thread density, the starting speed of the warp knitting machine can reach 1200 rpm, which can increase the knitting speed by 15-20% compared with existing ordinary four-comb structure fabrics.

[0019] In one embodiment, the first yarn is a 35D in-line fiber yarn, the second yarn is a 40D ultrafine denier nylon yarn, the third yarn is a 20D spandex yarn, and the fourth yarn is a 25D spandex yarn. The ultrafine denier yarn is a yarn with a denier number lower than 0.55D, preferably 0.4D. Using ultrafine denier nylon yarn combined with GB1 regenerated fiber yarn can complement the high breathability of the first yarn, ensuring consistent overall fabric breathability and overcoming the loop skew defect caused by the modulus difference between regenerated and chemical fibers. Ultrafine denier nylon also has a high surface area, thus achieving a treatment effect slightly inferior to GB1 natural fibers, while still maintaining good breathability and hydrophobicity.

[0020] The fabric is soaked in a solution of nano zinc oxide mixed with fluorine finishing agent. The nano-level zinc oxide has good adhesion, and the regenerated cellulose fibers have a high internal surface area due to their natural fiber characteristics. This results in a continuous fluorocarbon film layer mixed with nano zinc oxide on the inner surface of the fabric fibers, which has self-cleaning, hydrophobic, breathable and quick-drying properties.

[0021] A method for weaving a quantum breathable fabric containing regenerated Juncao fiber includes the following steps: A warp knitting machine with four guide bars (GB1, GB2, GB3, and GB4). The yarn threading codes and yarn threading patterns of GB1, GB2, GB3, and GB4 are as follows: GB1: 1-0 / 2-3 / 4-5 / 3-2 / / Yarn threading pattern is 1 thread 1 empty; GB2: 4-5 / 3-2 / 1-0 / 2-3 / / Yarn threading pattern is 1 empty 1 thread; GB3: 1-0 / 2-3 / 4-5 / 3-2 / / Yarn threading pattern is 1 thread 1 empty; GB4: 4 -5 / 3-2 / 1-0 / 2-3 / / The yarn threading structure is 1 empty 1 thread; GB1, GB2, GB3, and GB4 thread the first yarn, second yarn, third yarn, and fourth yarn respectively. The first yarn is a Juncao regenerated fiber yarn. GB1 and GB2 interweave with GB2 at needle positions 1-2 and 4-5 of each GB1, and the knitting actions of GB1 and GB2 are started and executed simultaneously. (ii) Quantum processing steps: After the fabric body is knitted, it is soaked in a solution of nano zinc oxide mixed with fluorine finishing agent at 160°C for 40-50 seconds. The fluorine finishing agent solution is a fluorine-containing finishing agent in the prior art with perfluoroalkyl acrylate as the main chain and C4-C8 fluorocarbon segments in the side chain, which is oriented through SO2N- or CON- linkage groups. Nano zinc oxide can provide ultraviolet protection and antibacterial properties, while the fluorine finishing agent enhances waterproof and stain-resistant properties. The combination is suitable for outdoor clothing, medical textiles, etc.

[0022] The GB1 and GB2 weaving actions are started and executed simultaneously to form an interlaced structure, which constitutes the outer and inner fabric structure of this fabric.

[0023] In the method described, the weight ratio of the first yarn to the second yarn is 1:1 to 1.2; the weight ratio of the third yarn to the fourth yarn is 1:0.8 to 1.4, wherein the second yarn is nylon yarn; and the third and fourth yarns are both spandex yarns. Preferably, the weight ratio of the first yarn to the second yarn is 1:1.1, and the weight ratio of the third yarn to the fourth yarn is 1:1.1.

[0024] The method described uses a 40-needle warp knitting machine, such as the Karl MayerHKS 4-M EL warp knitting machine.

[0025] The method described herein has a coil height ratio of 1:1:1.2:0.8 for GB1, GB2, GB3, and GB4, and the tension controls for GB1 and GB4 are 25±1 cN and 18±1 cN, respectively.

[0026] In the method described, the warp feed ratio of GB1 to GB3 is 1:1.2±0.1, and the warp feed ratio of GB2 to GB4 is 1:1.0±0.1. Preferably, the warp feed ratio of GB1 to GB3 is 1:1.2, and the warp feed ratio of GB2 to GB4 is 1:1.0. For reference, GB1 / GB3: 1200~1500mm / gram; GB2 / GB4: 1800~2200mm / gram.

[0027] In another embodiment, the first yarn is a 40D regenerated fiber yarn, the second yarn is a 40D ultrafine denier nylon yarn, the third yarn is a 25D spandex yarn, and the fourth yarn is a 30D spandex yarn. The ultrafine denier yarn is a yarn with a denier number lower than 0.55D, preferably 0.4D. Using ultrafine denier nylon yarn in combination with GB1 regenerated fiber yarn can complement the high breathability of the first yarn, ensuring consistent overall fabric breathability and overcoming the loop skewing defect caused by the modulus difference between regenerated and chemical fibers. Ultrafine denier nylon also has a high surface area, thus achieving a treatment effect slightly inferior to GB1 natural fibers, while still maintaining good breathability and hydrophobicity.

[0028] This fabric has natural antibacterial properties: Juncao fiber inhibits Staphylococcus aureus (antibacterial rate ≥99%); fast drying: moisture evaporation rate ≥0.35g / (m².s); high elasticity and deformation resistance: double spandex structure ensures a rebound rate ≥90% after long-term use; environmentally friendly and sustainable: Juncao fiber is biodegradable, reducing dependence on petroleum-based raw materials.

[0029] The above-disclosed embodiments are merely a few specific examples of the present invention, but the present invention is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
