Description

Technical Field

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

[0002] In today's society, with the increasing environmental awareness of people, the textile industry's demand for sustainable materials is growing. Recycled polyester, a fiber made from recycled materials such as waste polyester bottle flakes, has become an environmentally friendly alternative to traditional polyester fiber, aligning with the development concept of resource recycling and reducing the environmental impact of waste. At the same time, consumers' performance requirements for textiles are becoming increasingly diversified. They not only focus on basic physical properties such as strength and abrasion resistance, but also have higher expectations for functionality. In daily use, textiles can easily become breeding grounds for bacteria, especially in situations involving close contact with the human body, such as clothing and bedding. Bacterial growth on textiles can lead to various problems, such as unpleasant odors and reduced wearing comfort. Therefore, an antibacterial recycled polyester coated yarn is provided. Utility Model Content

[0003] The purpose of this invention is to provide an antibacterial recycled polyester coated yarn, which aims to use recycled polyester to replace traditional polyester fibers, making it more environmentally friendly, and its antibacterial properties can reduce the growth of bacteria.

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

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the elastic yarn is T400 filament.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the antibacterial yarn is polylactic acid fiber antibacterial composite yarn.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the outside of the first wrapping yarn is also covered with an antibacterial fiber layer.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the antibacterial fiber used in the antibacterial fiber layer is a cotton fiber with antibacterial and mosquito-repellent functions made from plant-based Chinese medicinal herbs.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the antibacterial fiber used in the antibacterial fiber layer is antibacterial, mildew-proof, and deodorizing viscose fiber.

[0010] The beneficial effects of this utility model are as follows: Based on the antibacterial recycled polyester covered yarn of this utility model, the first and second wrapped yarns form a mesh-like cross-binding and wrapping structure outside the core yarn, which enhances the overall wear resistance of the yarn. Recycled polyester, as a fiber made from recycled materials such as waste polyester bottle flakes, replaces traditional polyester fiber and has the advantage of being more environmentally friendly. The antibacterial yarn, as the second wrapped yarn, can provide excellent antibacterial effect to the yarn as a whole. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] Example 1

[0017] Combination Figure 1 This embodiment will be described in detail. An antibacterial recycled polyester covered yarn includes: a core yarn, a first wrapping yarn, and a second wrapping yarn; the first wrapping yarn and the second wrapping yarn are spirally wound around the outside of the core yarn in opposite directions; the core yarn is an elastic yarn; the first wrapping yarn is a recycled polyester fiber filament; and the second wrapping yarn is an antibacterial yarn.

[0018] The first and second wrapping yarns form a mesh-like cross-wrapping structure around the core yarn, significantly enhancing the yarn's structural stability. This mesh structure effectively reduces wear on the core yarn caused by external friction, greatly improving the overall abrasion resistance of the yarn. Recycled polyester, a fiber made from recycled materials such as waste polyester bottle flakes, replaces traditional polyester fibers and has a more environmentally friendly advantage.

[0019] Furthermore, the elastic yarn is T400 filament. T400 filament is composed of PET and PTT in parallel composite. The PET and PTT are processed and composited in a composite spinneret, and then stretched and heat-set to obtain T400 filament. T400 filament has a large elastic elongation and good elastic recovery, and its elasticity is better than that of PTT and PET fibers. It also has high tensile strength, a soft hand feel, good moisture absorption and perspiration wicking, and good wrinkle resistance, which can provide good elasticity for the yarn body.

[0020] Furthermore, the antibacterial yarn is a polylactic acid (PLA) fiber antibacterial composite yarn. This PLA fiber antibacterial composite yarn is obtained by combining PLA roving with PLA / PHBV filaments in the spinning process. PLA is a bio-based material and a low-energy product, its raw materials derived from renewable plant resources such as corn, wheat, and cassava. Waste PLA can be completely decomposed into carbon dioxide and water in the soil by microorganisms and water. Then, through plant photosynthesis, water and carbon dioxide can regenerate into starch-like substances, providing raw materials for PLA synthesis. Simultaneously, PLA possesses antibacterial properties. PHBV is an aliphatic polyester synthesized by microorganisms, possessing biodegradability and good biocompatibility. Produced by bacteria, it can be digested by bacteria and completely decomposed into carbon dioxide, water, and biomass under soil or composting conditions, without causing environmental pollution. The PLA / PHBV filament is a blend of PLA and PHBV. Polylactic acid fiber antibacterial composite yarn has an inhibition rate of more than 70% against Escherichia coli, Staphylococcus aureus and Candida albicans, and has excellent antibacterial properties.

[0021] Example 2

[0022] The difference from Embodiment 1 is that the first wrapping yarn is also covered with an antibacterial fiber layer.

[0023] Furthermore, the antibacterial fiber used in the antibacterial fiber layer is a herbal antibacterial and mosquito-repellent functional cotton fiber. A mixture of plant essential oil microcapsules, Nim tree fruit, and green tea extract is prepared at a certain concentration and then added to pretreated cotton fibers to obtain the herbal antibacterial and mosquito-repellent functional cotton fiber. Compared with ordinary cotton fiber, the herbal antibacterial and mosquito-repellent functional cotton fiber exhibits a 0.33 cN / dtex decrease in breaking strength, a 1.04% increase in breaking elongation, and a 1.51% increase in moisture regain. The antibacterial rates against Staphylococcus aureus, Escherichia coli, and Candida albicans are 98.6%, 97.22%, and 95.34%, respectively, and remain at 95.42%, 93.51%, and 90.46% after 20 washes, demonstrating excellent antibacterial effects and washability. The herbal antibacterial and mosquito-repellent cotton fiber has a mosquito repellency rate of 78.8%, which is extremely effective. After 20 washes, the repellency rate is 47.80%, and it still has a repellency effect.

[0024] Example 3

[0025] The difference from Example 2 lies in that the antibacterial fiber used in the antibacterial fiber layer is antibacterial, mildew-resistant, and deodorizing viscose fiber. This antibacterial, mildew-resistant, and deodorizing viscose fiber is prepared by blending licorice extract (with antibacterial properties), clove extract (with mildew-resistant properties), and sepiolite micropowder (with deodorizing properties) with viscose spinning solution using ordinary viscose fiber production processes. The antibacterial, mildew-resistant, and deodorizing viscose fiber exhibits a 99.81% inhibition rate against Staphylococcus aureus and a Grade 1 mildew resistance against Aspergillus niger, demonstrating excellent antibacterial and mildew-resistant effects. Furthermore, the deodorization rates against ammonia, acetic acid, and isovaleric acid are 93%, 97%, and 95%, respectively, demonstrating excellent deodorizing performance.
