Description

Technical Field

[0001] This utility model relates to the field of textile fabric technology, specifically to an antistatic and wrinkle-resistant polyester fabric. Background Technology

[0002] In the modern textile industry, polyester fabrics are widely used in clothing, home textiles, and industrial products due to their excellent properties such as high strength, good abrasion resistance, and wrinkle resistance. Existing technologies typically impart antistatic properties to polyester fabrics by adding antistatic agents or composite conductive fibers. However, these antistatic treatment processes often form a dense protective layer on the fabric surface or block the pores between fibers, resulting in a significant decrease in the fabric's breathability. Therefore, this invention provides an antistatic and wrinkle-resistant polyester fabric. Utility Model Content

[0003] The purpose of this invention is to provide an antistatic and wrinkle-resistant polyester fabric.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0005] An antistatic and wrinkle-resistant polyester fabric includes: a surface layer and an inner layer; the surface layer is disposed on one side of the inner layer;

[0006] The outer layer is woven from warp and weft yarns; the warp yarns include a first warp yarn and a second warp yarn arranged in a ratio of 1:5-10; the first warp yarn is flame-retardant polyester fiber yarn with an irregular cross-section; the second warp yarn is antistatic polyester composite yarn; the weft yarns include a first weft yarn and a second weft yarn arranged in a ratio of 1:5-10; the first weft yarn is flame-retardant polyester fiber yarn with an irregular cross-section; the second weft yarn is antistatic polyester composite yarn;

[0007] The antistatic polyester composite yarn is made of flame-retardant polyester fiber yarn with irregular cross-section and carbon fiber twisted together;

[0008] The inner layer is made of breathable and comfortable polyester composite yarn warp-knitted; the breathable and comfortable polyester composite yarn is made of irregular cross-section polyester filaments, bamboo fiber yarn and cotton fiber yarn twisted together.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme, the irregular cross-section polyester filament is an antibacterial irregular cross-section polyester filament.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme, the fineness of the irregular cross-section polyester filament is 50D / 36F-75D / 36F.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme, the cross-sectional shape of the polyester fiber in the flame-retardant irregular cross-section polyester fiber yarn is cross-shaped.

[0013] Based on the above scheme and as a preferred embodiment of the above scheme, a microporous flame-retardant polyurethane coating is provided on the side of the surface layer away from the inner layer.

[0014] The beneficial effects of this utility model are as follows: The outer layer of this utility model is made of warp and weft yarns arranged in a certain ratio. Both warp and weft yarns include polyester fiber yarns with irregular cross sections. The irregular cross sections of the polyester fibers create gaps between the yarns, which have better breathability than ordinary polyester fibers, thus improving the breathability of the outer layer. The inner layer is made of breathable and comfortable polyester composite yarn. The warp knitting structure itself has good breathability. The breathable and comfortable polyester composite yarn is made of irregular cross section polyester fiber yarn, bamboo fiber yarn and cotton fiber yarn twisted together, which also has good breathability.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1:

[0023] like Figure 1As shown, an antistatic and wrinkle-resistant polyester fabric includes: an outer layer 1 and an inner layer 2, wherein the outer layer 1 is disposed on one side of the inner layer 2 and is fixedly connected thereto.

[0024] The outer layer 1 is made of interwoven warp and weft yarns.

[0025] The warp yarns consist of a first warp yarn and a second warp yarn arranged in a 1:5-10 ratio. The first warp yarn is a flame-retardant, irregularly shaped cross-section polyester fiber yarn, and the second warp yarn is an antistatic polyester composite yarn. The weft yarns consist of a first weft yarn and a second weft yarn arranged in a 1:5-10 ratio. The first weft yarn is a flame-retardant, irregularly shaped cross-section polyester fiber yarn, and the second weft yarn is an antistatic polyester composite yarn.

[0026] like Figure 2 As shown, the antistatic polyester composite yarn is made by twisting flame-retardant profiled cross-section polyester fiber yarn 11 and carbon fiber 12 together. The flame-retardant profiled cross-section polyester fiber yarn 11 is spun from flame-retardant modified profiled cross-section polyester fibers. The preparation method of the flame-retardant modified profiled cross-section polyester fibers is as follows: flame-retardant masterbatch and PET chips are mixed and melted, extruded through profiled holes to form a melt stream, cooled and solidified by side blowing to form fibers, and then post-treated by winding and stretching. Compared with ordinary polyester fibers, the flame-retardant profiled cross-section polyester fiber yarn 11 has good flame retardancy and air permeability.

[0027] Carbon fiber 12 has excellent electrical conductivity and flame retardancy, which can improve the antistatic properties and flame retardancy of fabrics.

[0028] Inner layer 2 is made of breathable and comfortable polyester composite yarn warp-knitted, such as Figure 3 As shown, the breathable and comfortable polyester composite yarn is made of irregularly shaped cross-section polyester filament 13, bamboo fiber yarn 14, and cotton fiber yarn 15 twisted together. The irregularly shaped cross-section polyester filament 13 is an antibacterial type, obtained by melt spinning antibacterial masterbatch mixed with PET chips. Compared to ordinary polyester filament, it has an antibacterial effect, improving the antibacterial properties of the inner layer 2. Simultaneously, the irregularly shaped cross-section polyester filament 13 has a fineness of 50D / 36F-75D / 36F, making it a fine denier filament with a softer and more comfortable feel, further enhancing the comfort of the inner layer 2 and making the garments made from this fabric more comfortable to wear. Preferably, the cross-sectional shape of the polyester fibers in the flame-retardant irregularly shaped cross-section polyester fiber yarn 11 is cross-shaped.

[0029] The cross-section of the irregularly shaped polyester filament 13 is cross-shaped, which has better breathability than ordinary polyester filament. The bamboo fiber yarn 14 and cotton fiber yarn 15 are both natural fibers with good breathability. The combination of the three gives the inner layer 2 excellent breathability and good skin comfort.

[0030] Example 2:

[0031] like Figure 4As shown, this embodiment, based on Embodiment 1, adds a microporous flame-retardant polyurethane coating 3 to the side of the surface layer 1 away from the inner layer 2. The preparation method of the microporous flame-retardant polyurethane coating 3 is as follows: Flame retardant, pore-forming agent, and dispersant are added to water and stirred at high speed for 30 minutes to form a uniform slurry; polyurethane resin is slowly added and stirred at low speed for 20 minutes to avoid bubble formation; finally, a catalyst is added, and after stirring evenly, the mixture is filtered through a 100-mesh screen for later use; polyester fabric is fed into the padding tank via guide rollers, and the coating solution is immersed for 5-10 seconds, with excess coating solution removed by roller extrusion; pre-drying: hot air drying at 80-100℃ allows the pore-forming agent to initially migrate to the surface; baking: high-temperature baking at 150-180℃ promotes polyurethane cross-linking, while the pore-forming agent dissolves / evaporates to form micropores. The micropore diameter is smaller than a water droplet but larger than a water vapor molecule, achieving waterproof and breathable properties.

[0032] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
