Abstract
Description
Technical Field
[0001] This utility model relates to a polyester fabric, specifically an elastic and breathable polyester fabric. Background Technology
[0002] Polyester, as a synthetic fiber, is widely used in clothing, home textiles, and industrial fabrics due to its advantages such as high strength, good abrasion resistance, strong wrinkle resistance, and good shape retention. For example, traditional polyester fabrics are often used in outerwear, sportswear, tents, etc., and its chemical stability and durability meet basic usage requirements.
[0003] However, due to the regular molecular chain structure and high crystallinity of polyester, the fiber elongation is low, usually less than 30%, and its elastic recovery is poor. The fabric is easily deformed after being stretched by external forces, resulting in a strong feeling of restriction when worn, making it particularly unsuitable for scenarios requiring physical activity, such as sportswear and tight-fitting garments. Furthermore, polyester molecules lack hydrophilic groups, resulting in extremely low moisture absorption, with a moisture regain of only 0.4%-0.5%. The tightly packed fiber arrangement further hinders air circulation and moisture diffusion, making it difficult for sweat to evaporate, leading to a stuffy feeling when worn, and even causing bacterial growth and odor. Therefore, it is necessary to provide a stretchy and breathable polyester fabric. Utility Model Content
[0004] The purpose of this invention is to provide an elastic and breathable polyester fabric that, compared with ordinary polyester fabrics, has weft elasticity and certain moisture-wicking and antibacterial functions.
[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: an elastic and breathable polyester fabric, comprising: a fabric body, wherein the fabric body is a fancy perforated structure formed by interlacing warp and weft yarns; the fancy perforated structure includes a ground weave and a patterned weave, wherein the ground weave is a plain weave and the patterned weave is a perforated weave; the warp yarns include moisture-wicking yarns and antibacterial yarns, wherein the warp yarns are arranged in the order of one moisture-wicking yarn and one antibacterial yarn; and the weft yarns are elastic polyester yarns.
[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the warp yarn has an S-twist and the weft yarn has a Z-twist.
[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the moisture-wicking yarn is a U-shaped cross-section polyester filament.
[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the antibacterial yarn is a colored, low-melting-point, core-sheath type antibacterial polyester fiber filament.
[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the elastic polyester yarn is graphene-shaped polyester filament antibacterial spandex-coated yarn.
[0010] The beneficial effects of this utility model are as follows: Based on the elastic and breathable polyester fabric of this utility model, the weft yarn is made of elastic polyester yarn, which enables the weft direction of the fabric to quickly rebound after being stretched by external force, effectively improving the elongation rate of the fabric and reducing the feeling of restriction when wearing the fabric. The fancy perforated structure has more breathable channels, which enhances the air circulation of the fabric and improves the breathability. The moisture-wicking yarn in the warp yarn is conducive to quickly conducting the sweat and moisture excreted by the human body to the outside. The antibacterial yarn can play an antibacterial role, which is conducive to inhibiting the growth of bacteria and avoiding odor caused by sweat residue. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Specifically, one cycle of the fancy openwork weave is formed by the interlacing of twenty-eight warp yarns and twenty-four weft yarns. The warp yarns floating on the weft yarns are the warp weave points, and the weft yarns floating on the warp yarns are the weft weave points. In the fabric weave diagram, from left to right, the interlacing patterns of the first to twenty-eighth warp yarns with the weft yarns are as follows:
[0016] First warp thread: up and down ...;

[0044] Furthermore, the warp yarns are twisted in an S-direction, and the weft yarns are twisted in a Z-direction. Using different twist directions for the warp and weft yarns results in better light reflection on the fabric surface. Simultaneously, the perforated weave structure, with its evenly distributed small pores on the surface, improves the breathability of the fabric.
[0045] Furthermore, the moisture-wicking yarn is a U-shaped cross-section polyester filament. U-shaped cross-section polyester filament is a fiber produced using U-shaped spinnerets and is a differentiated fiber. The cross-section of U-shaped polyester filament resembles the English letter U. Because the fiber grooves are deep, some fibers are even flattened, causing the grooves to disappear. When this structured fiber is formed into a fabric, it easily generates more fine grooves, thus forming more capillary channels, which is very beneficial for moisture conduction. In addition, it has a large specific surface area, resulting in fabrics formed from U-shaped cross-section polyester filament with excellent moisture-wicking and quick-drying properties.
[0046] Furthermore, the antibacterial yarn is a colored, low-melting-point, core-sheath type antibacterial polyester fiber filament. The preparation process of the colored, low-melting-point, core-sheath type antibacterial polyester fiber includes: antibacterial agent preparation: mixing 3 kg KGM, 0.25 kg nano-silver wire, 15 kg bamboo charcoal powder, and 90 kg water, stirring vigorously for 20 minutes at a stirring speed of 11000 r / min, letting stand for 30 hours, filtering, and drying at 90℃ to constant weight to obtain the antibacterial agent; and preparation of the sheath raw material: vacuum drying 100 kg of low-melting-point polyester chips for 4 hours at a drying temperature of 60℃ and a vacuum degree of -0.16 MPa, adding 2.5 kg of color masterbatch and 2.5 kg of antibacterial agent, and high-pressure grinding for 16 minutes. The sheath material was obtained by grinding at a force of 0.3 MPa and a grinding speed of 3000 r / min. The core material was prepared by uniformly mixing 100 kg of ordinary polyester, 2 kg of HPMA, and 1.5 kg of antioxidant TNP. 2 kg of sheath material and 10 kg of core material were fed into a composite spinning assembly for spinning at 180℃. After cooling and solidification, nascent fibers were obtained. These fibers were then oiled, wound on a winding machine, and then subjected to secondary heating and stretching at 145℃ with a stretch ratio of 5.4 to obtain colored, low-melting-point, sheath-core type antibacterial polyester fiber. The colored, low-melting-point, sheath-core type antibacterial polyester fiber exhibited an antibacterial rate of 99.8% against Staphylococcus aureus and 97.9% against Streptococcus albus. After 20 washes at 40℃, the antibacterial performance retention rate was 95%, demonstrating excellent antibacterial effect.
[0047] Furthermore, the elastic polyester yarn is a graphene-shaped polyester filament antibacterial spandex-coated yarn. The outer fiber of the graphene-shaped polyester filament antibacterial spandex-coated yarn is graphene-shaped polyester filament, which is prepared by melt-blending graphene functional masterbatch with ordinary polyester masterbatch and spinning using a cross-shaped cross-section spinneret. The graphene material endows the yarn with excellent antibacterial, anti-mite, UV protection, and antistatic properties. The cross-shaped cross-section structure of the fiber increases the specific surface area and capillary effect, improving the fiber's moisture absorption and wicking capacity. It can conduct sweat and moisture excreted by the human body to the outside through the wicking effect, thereby keeping the skin dry and comfortable. The core yarn is antibacterial spandex filament, which is prepared by adding a nano-anion carrier antibacterial agent to the original spandex spinning solution in a certain proportion. Silver ions can deodorize while sterilizing, which can give full play to the elasticity and wrinkle resistance of spandex, and also has a long-lasting and strong antibacterial, sterilizing and deodorizing effect.
