Description

Technical Field

[0001] This utility model relates to a covered yarn, specifically a polyester covered yarn. Background Technology

[0002] Polyester is an important type of synthetic fiber. With the development of the petrochemical industry, the supply of raw materials has become increasingly abundant, laying the foundation for large-scale polyester production. Simultaneously, continuous improvements in polymerization technology and spinning processes have enhanced the quality and performance of polyester fibers. However, single polyester filaments have limitations in certain properties. For example, polyester fibers have poor moisture absorption and lack antibacterial properties, which restricts their use in applications requiring high comfort, such as sportswear and underwear. Furthermore, when diverse fabric appearances are desired, the inherent luster and feel of polyester may not be ideal for some fashion designs. To address these issues, it is necessary to provide a polyester covered yarn. Utility Model Content

[0003] The purpose of this invention is to provide a polyester covered yarn, which aims to utilize the moisture-wicking and antibacterial properties of the covered yarn to endow the yarn with multiple properties, thereby improving the problem of the single performance of ordinary polyester filament.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: a polyester covered yarn, comprising: a core yarn, a covering fiber layer, a first wrapping yarn, and a second wrapping yarn; the covering fiber layer covers the outside of the core yarn; the first wrapping yarn and the second wrapping yarn are spirally wound around the outside of the covering fiber layer in opposite directions; the core yarn is a polyester fiber filament; the covering fiber layer is an antibacterial fiber layer; the first wrapping yarn is a moisture-wicking antibacterial yarn; and the second wrapping yarn is an ultraviolet-resistant yarn.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the antibacterial fiber used in the antibacterial fiber layer is seaweed fiber.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the moisture-wicking antibacterial yarn is a cross-section antibacterial nylon filament.

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

[0015] Example 1

[0016] Combination Figure 1 This embodiment provides a detailed description of a polyester covered yarn, comprising: a core yarn 1, a covering fiber layer 2, a first wrapping yarn 3, and a second wrapping yarn 4; the covering fiber layer 2 covers the outside of the core yarn 1; the first wrapping yarn 3 and the second wrapping yarn 4 are spirally wound around the outside of the covering fiber layer 2 in opposite directions; the core yarn 1 is a polyester fiber filament; the covering fiber layer 2 is an antibacterial fiber layer; the first wrapping yarn 3 is a moisture-wicking antibacterial yarn; and the second wrapping yarn 4 is an ultraviolet-resistant yarn.

[0017] The first wrapping yarn 3 and the second wrapping yarn 4 form a mesh-like cross-binding and wrapping structure on the outside of the fiber layer 2, which greatly enhances the structural stability of the yarn. This mesh structure can effectively reduce the wear of the core yarn 1 caused by external friction and greatly help to improve the overall wear resistance of the yarn.

[0018] Furthermore, the antibacterial fiber used in the antibacterial fiber layer is seaweed fiber. Seaweed fiber is a fiber produced by wet spinning using sodium alginate isolated from seaweed plants as raw material. Based on the characteristics of sodium alginate being non-toxic, flame-retardant, and biocompatible, seaweed fiber has significant advantages in terms of moisture absorption and breathability, antibacterial properties, flame retardancy, far-infrared radiation, electromagnetic radiation protection, biocompatibility, and biodegradability. The trace amounts of lactic acid or oligomers in seaweed fiber give it a certain antibacterial effect, with antibacterial rates of 81.8% and 97.4% against Staphylococcus aureus and Escherichia coli, respectively, demonstrating excellent antibacterial effects.

[0019] Furthermore, the moisture-wicking and antibacterial yarn is a cross-section antibacterial nylon filament. The antibacterial nylon filament is made by mixing 5% layered nano-silver antibacterial material into nylon 6 masterbatch chips and using blending spinning technology to produce fibers that can produce odors and have long-lasting antibacterial function. The fiber cross-section is cross-shaped, which can quickly wick away and transfer sweat, keeping the skin dry.

[0020] Furthermore, the UV-protective yarn is an antibacterial and UV-protective polylactic acid (PLA) ZnO fiber filament. The antibacterial and UV-protective PLA ZnO fiber filament is produced by melt blending PLA / ZnO blends using ZnO as the functional particle, followed by melt spinning. Specifically, the mass fraction of ZnO masterbatch in the PLA is 5%. The PLA / ZnO blend exhibits excellent UV protection and antibacterial properties, increasing the UV protection factor from 1.43 for pure PLA to 663 for the blend. It achieves an inhibition rate of over 99% against Escherichia coli and Staphylococcus aureus, demonstrating excellent antibacterial activity, and retains a 99% inhibition rate even after 10 washes.

[0021] Example 2

[0022] The difference from Example 1 is that the UV-resistant yarn is a cationic dyeable UV-resistant polyamide 6 fiber filament. The cationic dyeable UV-resistant polyamide 6 fiber filament is prepared by using anatase titanium dioxide powder as raw material, surface modification of titanium dioxide with alumina and sodium isophthalic acid-5-sulfonate to create a bifunctional additive, and then preparing it through in-situ polymerization and melt spinning. Anatase titanium dioxide has a UV absorption edge initiation wavelength of 387.5 nm, making it an excellent UV absorber. The cationic dyeable UV-resistant polyamide 6 fiber filament exhibits good dyeing performance for cationic dyes, with a dye uptake rate of 45%, a UV transmittance of less than 2.5%, and an UV resistance factor value greater than 50, demonstrating excellent UV resistance.

[0023] Example 3

[0024] Combination Figure 2This embodiment will be described in detail. Based on Embodiment 1, the first wrapping yarn 3 and the second wrapping yarn 4 are coated with a mosquito repellent finishing agent 5. Specifically, in this embodiment, the mosquito repellent finishing agent 5 is an environmentally friendly insect repellent finishing agent AI-C, whose main components are nano-sized microcapsules of pyrethroid compounds. Through a fixative agent, an insect repellent film is formed on the surface of the first wrapping yarn 3 and the second wrapping yarn 4, achieving a slow-release effect. This allows the mosquito repellent adjuvant to be slowly released through friction, high temperature, or rubbing, achieving a long-lasting mosquito repellent effect.

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.
