Description

Technical Field

[0001] This utility model relates to a wear-resistant and breathable polyester fabric, belonging to the field of textile fabric technology. Background Technology

[0002] Polyester fabric is a common synthetic fiber clothing material, possessing advantages such as high strength, wrinkle resistance, and good shape retention. It is often used to make outdoor products and home textiles, including outerwear, bags, tents, and sofa covers. However, polyester fabric suffers from poor breathability, making users feel stuffy and hot. Furthermore, its moisture absorption is not as good as natural fibers like cotton. In addition, although polyester fabric itself has a certain degree of abrasion resistance, its resistance still needs improvement in certain special scenarios, such as outdoor activities involving frequent friction with hard objects. Therefore, this application provides an abrasion-resistant and breathable polyester fabric. Utility Model Content

[0003] The purpose of this invention is to provide a wear-resistant and breathable polyester fabric that has better wear resistance and breathability compared to traditional polyester fabrics.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: a wear-resistant and breathable polyester fabric, comprising: a fabric body, wherein the fabric body is woven from warp and weft yarns, the warp yarns include surface warp yarns and inner warp yarns, the weft yarns include surface weft yarns, inner weft yarns and bonding weft yarns, the surface warp yarns and surface weft yarns interweave to form a surface layer, the inner warp yarns and inner weft yarns interweave to form an inner layer, and the surface layer and inner layer are connected by bonding weft yarns; both the surface layer and the inner layer are perforated structures; the surface warp yarns are wear-resistant yarns, and the surface weft yarns and bonding weft yarns are anti-pilling polyester yarns; the inner warp yarns are moisture-wicking polyester filaments, and the inner weft yarns are antibacterial yarns.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the wear-resistant yarn is a bio-based nylon filament.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the anti-pilling polyester yarn is a double anti-pilling polyester fiber yarn.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the moisture-wicking polyester filament 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 chitosan-based silver-loaded antibacterial polyester yarn.

[0009] The beneficial effects of this invention are as follows: Based on the wear-resistant and breathable polyester fabric of this invention, both the outer and inner layers of the fabric adopt a perforated structure. This structure forms uniform small holes through the effects of tension difference, tangent lines, and long floats. These small holes can effectively promote air circulation, breaking the limitation of poor breathability of traditional polyester fabrics and reducing the stuffiness of the wearer; the wear-resistant yarn and anti-pilling polyester yarn are used to improve the wear resistance and anti-pilling performance of the main body of the fabric, and the moisture-wicking polyester filaments enhance the fabric's moisture-wicking and perspiration-driving ability.

Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0012] Combination Figure 1-2 This embodiment provides a detailed description of a wear-resistant and breathable polyester fabric, comprising: a fabric body, the fabric body being woven from warp and weft yarns, the warp yarns including surface warp yarns and inner warp yarns, the weft yarns including surface weft yarns, inner weft yarns, and knotted weft yarns, the surface warp and surface weft yarns interweaving to form a surface layer 1, the inner warp and inner weft yarns interweaving to form an inner layer 2, the surface layer 1 and inner layer 2 being connected by knotted weft yarns; both surface layer 1 and inner layer 2 are perforated structures; the surface warp yarns are wear-resistant yarns, the surface weft yarns and knotted weft yarns are both anti-pilling polyester yarns; the inner warp yarns are moisture-wicking polyester filaments, and the inner weft yarns are antibacterial yarns.

[0013] The surface of a perforated fabric has evenly distributed small pores, resembling a leno weave in appearance, hence it is also called a pseudo-leno weave. These pores are formed by differences in the weave's tightness, the presence of tangents, and the bundling effect of long floats. Within a weave repeat, some warp or weft yarns, due to different weaving patterns, do not easily come together. However, under the influence of long floats, adjacent yarns are brought closer together, creating gaps between them. These gaps constitute the pores of the perforated fabric, which can improve the breathability of the main body of the fabric to a certain extent.

[0014] Furthermore, the wear-resistant yarn is a bio-based nylon filament. Bio-based nylon is a polyamide product produced by converting alkanes, bio-based alkanes, oil scraps, fatty acids, and biomass into pentanediamine through a bioprocess, followed by polymerization. Bio-based nylon has better wear resistance than nylon 6, mainly because it possesses higher tensile strength and elongation, allowing it to store more tensile energy. During friction, the fibers are subjected to repeated stress; fabrics with higher tensile strength and elongation can better withstand this stress, thus exhibiting better wear resistance.

[0015] Furthermore, the anti-pilling polyester yarn is a double-anti-pilling polyester fiber yarn. Double-anti-pilling polyester fiber refers to ordinary polyester fiber that has been modified by chemical or physical methods to obtain polyester fiber with anti-pilling and antistatic properties. The breaking strength, breaking strength unevenness, and breaking elongation of double-anti-pilling polyester fiber are all lower than those of ordinary polyester fiber and are close to those of viscose fiber. The fuzz on the surface of its fabric is easily abraded away, and a large number of pills are not formed, thus it has a good anti-pilling effect. The moisture regain of double-anti-pilling polyester fiber is greater than 0.56%, which is higher than that of ordinary polyester fiber. Moreover, double-anti-pilling polyester fiber has a porous internal structure and good wicking performance, which enhances the conductivity of double-anti-pilling polyester and gives it good antistatic properties.

[0016] Furthermore, the moisture-wicking polyester filament 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.

[0017] Furthermore, the antibacterial yarn is a chitosan-based silver-loaded antibacterial polyester yarn. This chitosan-based silver-loaded antibacterial polyester yarn is a polyester yarn with a chitosan-based silver-loaded antibacterial coating on its surface. The chitosan-based silver-loaded antibacterial coating solution consists of nano-silver particles (antibacterial drug), a chitosan drug sustained-release carrier, and acetic acid solvent. Its preparation process is as follows: a certain mass of chitosan is weighed and added to a 2% acetic acid solution, and magnetically stirred for approximately 24 hours. After the chitosan is completely dissolved, a certain amount of silver nitrate is added, and the mixture is magnetically stirred for approximately 30 minutes under light-protected conditions until the drug is completely dissolved and uniformly dispersed. Then, a certain amount of the above solution is irradiated with ultraviolet light for a certain period to obtain the chitosan-based silver-loaded antibacterial coating solution. When the chitosan content is 2%, the coating is two layers, and the silver nitrate content is 0.8%, the diameter of the inhibition zone against Staphylococcus aureus and Escherichia coli is significantly increased, exhibiting a better antibacterial effect and significantly improving the antibacterial performance of the polyester yarn.

[0018] 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.
