Description

Technical Field

[0001] This utility model relates to a polyester fabric, specifically a sun-protective and breathable polyester fabric. Background Technology

[0002] Polyester fabric is an important type of synthetic fiber. Due to its numerous advantages, such as high strength, good elasticity, excellent abrasion resistance, easy washing and quick drying, and non-deformation, it is widely used in clothing, home textiles, and industrial textiles. However, with the improvement of people's living standards and the increasing demand for functionality, the performance of traditional polyester fabrics in some aspects is gradually failing to meet consumer expectations. With environmental changes and increased outdoor activities, the harmful effects of ultraviolet radiation on the human body are receiving more and more attention, leading to a growing demand for textiles with sun protection functions. Furthermore, when wearing clothing, the skin constantly metabolizes, releasing sweat and moisture. If the fabric is not breathable, sweat and moisture cannot be released in time, creating a stuffy and humid environment on the skin surface, causing discomfort. Therefore, it is necessary to provide a sun-protective and breathable polyester fabric. Utility Model Content

[0003] The purpose of this invention is to provide a sun-protective and breathable polyester fabric that combines good sun protection with breathability, thus better meeting consumer needs.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: a sun-protective and breathable polyester fabric, comprising: a sun-protective layer and a moisture-wicking and antibacterial layer, wherein the sun-protective layer and the moisture-wicking and antibacterial layer are connected by stitching; both the sun-protective layer and the moisture-wicking and antibacterial layer are eight-end satin weaves; the side of the sun-protective layer showing the warp satin weave is close to the side of the moisture-wicking and antibacterial layer showing the weft satin weave; the sun-protective layer is woven from a first warp yarn and a first weft yarn; the first weft yarn is a sun-protective yarn; the moisture-wicking and antibacterial layer is woven from a second warp yarn and a second weft yarn; the second warp yarn is a moisture-wicking yarn, and the second weft yarn is an antibacterial yarn; the moisture-wicking yarn is a U-shaped cross-section polyester filament.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the first warp yarn is hemp fiber yarn.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the sun protection yarn is an anti-ultraviolet matte polyester fiber filament.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the sun protection yarn is a cationic dyeable UV-resistant polyamide 6 fiber filament.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the antibacterial yarn is coral fiber yarn.

[0009] The beneficial effects of this utility model are as follows: Based on the sun-protective and breathable polyester fabric of this utility model, the eight-end satin weave has fewer warp and weft yarns interlacing, the yarns are relatively less tightly arranged, with larger gaps and more pores, allowing a large amount of gas to pass through the satin fabric, resulting in good breathability. The sun-protective layer has excellent UV protection function and good sun protection effect. The moisture-wicking and antibacterial layer has the warp satin side closer to the user, which is conducive to the wicking away of sweat and moisture, while the weft satin side has a good antibacterial effect, which can reduce the growth of bacteria caused by sweat and moisture.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Combination Figure 1-3 This embodiment provides a detailed description of a sun-protective and breathable polyester fabric, comprising: a sun-protective layer 1 and a moisture-wicking and antibacterial layer 2, wherein the sun-protective layer 1 and the moisture-wicking and antibacterial layer 2 are connected by stitching; both the sun-protective layer 1 and the moisture-wicking and antibacterial layer 2 are eight-end satin weaves; the side of the sun-protective layer 1 showing the warp satin weave is close to the side of the moisture-wicking and antibacterial layer 2 showing the weft satin weave; the sun-protective layer 1 is woven from a first warp yarn and a first weft yarn; the first weft yarn is a sun-protective yarn; the moisture-wicking and antibacterial layer 2 is woven from a second warp yarn and a second weft yarn; the second warp yarn is a moisture-wicking yarn, and the second weft yarn is an antibacterial yarn; the moisture-wicking yarn is a U-shaped cross-section polyester filament.

[0016] In the weaving process of an eight-end satin weave, the warp and weft yarns interweave less frequently, the warp points are discontinuous, and the arrangement of the satin weave yarns is relatively loose, with large gaps and many pores. Therefore, a large amount of air can pass through the satin fabric, resulting in good air permeability.

[0017] U-shaped cross-section polyester filament is a fiber produced using U-shaped spinnerets. It is a differentiated fiber. The cross-section of U-shaped polyester filament resembles the shape of the English letter U. Because the fiber grooves are deep, some fibers are even flattened, causing the grooves to disappear. When fibers with this structure are formed into fabric, they are more likely to produce more fine grooves, thus forming more capillary channels, which is very conducive to the conduction of moisture. In addition, it has a large specific surface area, and fabrics formed from U-shaped cross-section polyester filament have good moisture-wicking and quick-drying properties.

[0018] Furthermore, the first warp yarn is hemp fiber yarn. Hemp fiber is a cellulose fiber, which has good moisture absorption, moisture dissipation and breathability. It also has fast heat transfer and conduction, is cool and crisp, does not stick to the body when sweating, is lightweight, strong, and does not easily generate static electricity.

[0019] Furthermore, the sun-protective yarn is an anti-UV matte polyester fiber filament. This anti-UV matte polyester fiber filament is prepared by melt spinning, blending cerium dioxide-titanium dioxide functional composite powder (mass ratio 1:1) with PET chips. The fabric exhibits a UPF of 372+, with a long-wave UV transmittance of less than 3.67% and a minimum medium-wave UV transmittance of 0.05%. It achieves excellent UV protection under both normal and humid conditions, thus possessing good sun protection performance.

[0020] Furthermore, the antibacterial yarn is *Sarcandra glabra* fiber yarn. The main components of *Sarcandra glabra* are astilbene, isoflavones, rhamnosyl glucoside, tannins, azithromycin, and fraxin, which have antibacterial and anti-inflammatory effects, exhibiting good antibacterial and bacteriostatic effects against *Staphylococcus aureus*, *Candida albicans*, and *Escherichia coli*. *Sarcandra glabra* fiber is made by blending *Sarcandra glabra* extract with viscose fiber spinning solution. *Sarcandra glabra* fiber not only possesses the pharmacological effects of *Sarcandra glabra*, such as antibacterial, anti-inflammatory, and dehumidifying properties, but also has natural antibacterial functions, exhibiting good antibacterial activity against *Staphylococcus aureus*, *Escherichia coli*, and *Candida albicans*, with an inhibition rate reaching 99%, and retaining its antibacterial properties even after multiple washes.

[0021] Example 2

[0022] The difference from Example 1 is that the sunscreen yarn is a cationic dyeable UV-resistant polyamide 6 fiber filament. Using anatase titanium dioxide powder as raw material, an additive is prepared by surface modification of titanium dioxide with alumina and sodium isophthalate-5-sulfonate. This additive is then melt-spun using an in-situ polymerization agent to produce cationic dyeable UV-resistant polyamide 6 fiber filaments. The fabric exhibits a UV transmittance of less than 2.5% and a UV resistance factor value greater than 50, demonstrating excellent UV resistance and thus providing good sun protection.

[0023] 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.
