Abstract
Description
Technical Field
[0001] This utility model discloses an environmentally friendly and breathable yarn and fabric, belonging to the field of textile technology. Background Technology
[0002] Currently, synthetic fiber yarns, widely used in the textile industry, have become the mainstream material due to their excellent mechanical properties and durability. However, their raw materials mainly rely on non-renewable petroleum-based resources, resulting in high energy consumption and significant carbon emissions during production. Furthermore, synthetic yarns are difficult to degrade naturally after disposal, and long-term accumulation or landfilling leads to microplastic pollution, posing a serious threat to soil and marine ecosystems. Although some companies have attempted to alleviate environmental pressure through recycling, the complex processes and high costs have limited the actual effectiveness of promotion, failing to fundamentally address the environmental burden of synthetic fiber yarns throughout their lifecycle.
[0003] On the other hand, while natural biodegradable fiber yarns and emerging biodegradable synthetic fiber yarns are environmentally friendly, their mechanical properties are generally insufficient, especially in terms of tensile strength, abrasion resistance, and weather resistance, making them unsuitable for practical applications in industrial weaving, outdoor textiles, or high-load clothing. Existing technologies that improve the performance of natural yarns through physical or chemical modification often weaken their biodegradability advantages due to complex processes or the introduction of non-environmentally friendly additives, resulting in a trade-off between environmental friendliness and performance. Therefore, a new product needs to be developed to address this issue. Utility Model Content
[0004] The purpose of this utility model is to provide an environmentally friendly and breathable yarn and fabric to solve the above-mentioned problems.
[0005] This utility model achieves the above-mentioned objective through the following technical solution: an environmentally friendly and breathable yarn, comprising a yarn body, wherein the yarn body includes a base support yarn, and a plurality of strength reinforcing yarns are wound around the base support yarn, wherein the strength reinforcing yarns are high-twist yarns with a twist greater than 1500 twists / meter, and a plurality of environmentally friendly degradable fiber yarns are wound around the strength reinforcing yarns, wherein the environmentally friendly degradable fiber yarns are low-twist yarns with a twist less than 400 twists / meter.
[0006] Preferably, the strength-enhancing yarn is a Z-twist yarn.
[0007] Preferably, the environmentally friendly degradable fiber yarn is configured as an S-twist yarn.
[0008] Preferably, the strength-enhancing yarn is configured as a non-circular cross-section yarn, and the non-circular cross-section is configured as X-shaped.
[0009] An environmentally friendly and breathable fabric, woven from environmentally friendly and breathable yarn.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] By combining the inner layer of high-twist strength-enhancing yarn with the base layer of support yarn, the tensile strength and abrasion resistance of the yarn are significantly improved, ensuring the high strength and toughness of the inner core. At the same time, the outer layer of low-twist environmentally friendly biodegradable fiber yarn retains the soft and breathable characteristics of natural fibers, achieving dual optimization of mechanical performance and comfort. After the outer layer of environmentally friendly biodegradable fiber yarn degrades naturally, the inner layer of support yarn and strength-enhancing yarn can be recycled, or the damaged outer layer can be peeled off through active degradation treatment, and the intact and qualified inner core can be directly rewound with new environmentally friendly yarn, thus achieving recycling. This not only extends the material's life cycle but also reduces waste pollution, taking into account both environmental efficiency and efficient resource utilization. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0015] An environmentally friendly and breathable fabric, made from... Figure 1 The yarn shown is woven from environmentally friendly and breathable yarn. The yarn includes a yarn body 1, which in turn includes a base support yarn 2. The base support yarn 2 can be made of PTT fiber, which has elasticity similar to spandex but stronger chemical corrosion resistance. Therefore, as the inner core of the yarn, it can ensure the yarn's shape, elasticity, and service life.
[0016] The base support yarn 2 is wrapped with several strength reinforcing yarns 3, which can be made of high-strength, high-modulus polyethylene fiber. This fiber is twice as strong as carbon fiber, and is resistant to cutting, corrosion, and has excellent UV resistance. The strength reinforcing yarn 3 is set as a high-twist yarn with a twist of more than 1500 twists / meter. The high twist can give it higher yarn strength and abrasion resistance. The strength reinforcing yarn 3 is set as a Z-twist yarn. This twisting method can make the fibers of the strength reinforcing yarn 3 more tightly bound, further improving the yarn strength and abrasion resistance while reducing the exposure of hair during processing.
[0017] The strength-enhancing yarn 3 is set as a yarn with an irregular cross section, and the irregular cross section is set as X-shaped. Therefore, there will be several gap channels on the layer formed by winding and twisting the strength-enhancing yarn 3, so that the airflow can be better circulated, the sweat can be better guided, and the breathability and moisture-wicking ability of the yarn can be increased.
[0018] The strength-enhancing yarn 3 is wrapped with several environmentally friendly biodegradable fiber yarns 4, which can be made of PLA fiber filaments. These filaments are made from plants such as corn and sugarcane, and can decompose into carbon dioxide and water. They are non-toxic and have excellent biocompatibility. In addition to their excellent environmental performance, they also have natural antibacterial, mildew-proof, mite-proof, flame-retardant, UV-resistant, oxygen-permeable, and moisture-permeable properties, which can further improve the overall performance of the yarn. The environmentally friendly biodegradable fiber yarn 4 is set as a low-twist yarn with a twist of less than 400 twists / meter. The low twist makes the surface fiber arrangement of the yarn loose, making the yarn soft, fluffy, and skin-friendly. The larger fiber gaps also result in excellent breathability and moisture absorption. Furthermore, the environmentally friendly biodegradable fiber yarn 4 is set as an S-twist yarn. This twisting method makes the fiber arrangement even looser, giving the fabric better breathability and elasticity. The twist stress is released evenly, reducing fabric wrinkling and deformation.
[0019] This utility model's environmentally friendly and breathable yarn significantly improves the yarn's tensile strength and abrasion resistance through the combination of an inner high-twist strength-enhancing yarn 3 and a base support yarn 2, ensuring the high strength and toughness of the inner core. At the same time, the outer low-twist environmentally degradable fiber yarn 4 retains the soft and breathable characteristics of natural fibers, achieving a dual optimization of mechanical performance and comfort. Furthermore, after the outer environmentally degradable fiber yarn 4 naturally degrades, the inner base support yarn 2 and strength-enhancing yarn 3 can be recycled, or the damaged outer layer can be peeled off through active degradation treatment, and new environmentally degradable fiber yarn 4 can be directly rewound onto the intact and qualified inner core, thus achieving recycling. This not only extends the material's life cycle but also reduces waste pollution, taking into account both environmental efficiency and efficient resource utilization.
