Description

Technical Field

[0001] This utility model relates to the field of fabric technology, specifically to a moisture-wicking polyester staple fiber. Background Technology

[0002] Polyester staple fiber is obtained by cutting polyester spun into tows. Polyester is the world's largest-produced and most widely used synthetic fiber, accounting for over 60% of global synthetic fiber production. It is extensively used in textiles such as clothing, bedding, various decorative fabrics, and special textiles for national defense and military applications, as well as other industrial fiber products such as filter materials, insulation materials, tire cords, and conveyor belts. However, polyester experiences significant wear and tear over prolonged use, leading to a substantial decrease in the strength of polyester products and affecting their normal use.

[0003] A search revealed that patent document CN218404574U discloses a polyester staple fiber, belonging to the field of chemical fibers. It includes a core layer and an abrasion-resistant outer layer wrapped around the core layer. The core layer is formed by winding six strands of polyester core yarn, and the abrasion-resistant outer layer is formed by twisting spandex fibers. Elastic fibers and strong fibers are spirally wrapped around the outer side of the abrasion-resistant outer layer, with two strands of each fiber. This invention strengthens the overall strength of the core layer from the inside by twisting six strands of polyester core yarn. The high density of the polyester core yarn ensures the toughness of the core layer, while the high density of the spandex fiber abrasion-resistant outer layer improves its overall strength and protects the core layer from damage. Furthermore, the spiral winding of the elastic and strong fibers into the abrasion-resistant outer layer forms an elastic layer, increasing the density between the abrasion-resistant outer layer and the core layer, thus enhancing the protection of the core layer by the abrasion-resistant outer layer. The aforementioned patent has certain drawbacks: for example, polyester staple fiber does not have fire-retardant properties, and polyester staple fiber is prone to melting at high temperatures, producing a large amount of dense smoke and dripping substances when burned, causing the fire to spread rapidly. Therefore, it cannot meet the usage requirements. Hence, a moisture-wicking polyester staple fiber is proposed to solve the problems mentioned above. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a moisture-wicking polyester staple fiber with advantages such as good protective effect, and solves the problem that polyester staple fiber does not have fire-retardant function.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sweat-wicking polyester staple fiber, comprising a core layer and an abrasion-resistant outer layer wrapped around the outside of the core layer, wherein elastic fibers and strong fibers are spirally wrapped around the outside of the abrasion-resistant outer layer, and the elastic fibers and strong fibers are arranged alternately to form an elastic layer on the outside of the abrasion-resistant outer layer;

[0006] The elastic layer is provided with a moisture-wicking spun layer on the outside, and a blended spun layer is provided on the outside of the moisture-wicking spun layer. The blended spun layer is made of conductive fibers and UV-resistant fibers. The conductive fibers and UV-resistant fibers are interwoven and wrapped around the outside of the moisture-wicking spun layer. A protective layer is provided on the outer surface of the blended spun layer.

[0007] The protective layer consists of a waterproof layer and a fireproof layer.

[0008] Furthermore, the moisture-wicking spun layer includes an antibacterial layer woven from antibacterial fiber bundles and a moisture-wicking mesh layer woven from moisture-wicking fibers. The moisture-wicking mesh layer is woven from bamboo charcoal fiber and has honeycomb-shaped mesh holes formed in the moisture-wicking spun layer.

[0009] Furthermore, the antibacterial fiber bundle includes a base yarn and a first antibacterial yarn and a second antibacterial yarn interlaced around the outside of the base yarn. The first antibacterial yarn and the second antibacterial yarn are respectively made of silver ion fiber and copper ion complexed cellulose fiber.

[0010] Furthermore, the waterproof layer and the fireproof layer are arranged sequentially from the inside out. The waterproof layer is a polyvinyl chloride waterproof membrane, and the outer surface of the protective layer is also provided with a windproof coating.

[0011] Furthermore, the core layer is made of six strands of polyester core yarn wound together.

[0012] Compared with the prior art, this utility model provides a moisture-wicking polyester staple fiber, which has the following beneficial effects:

[0013] 1. This moisture-wicking polyester staple fiber, through the design of a protective layer, possesses both waterproof and fire-retardant properties. The waterproof function allows the polyester staple fiber fabric to remain dry even in humid environments, improving wearing comfort and preventing discomfort caused by moisture. Furthermore, the fire-retardant function can, to a certain extent, inhibit the spread of fire, reducing the risk of fire and protecting people's lives and property, achieving excellent protective effects and solving the problem of polyester staple fiber lacking fire resistance. 2. This moisture-wicking polyester staple fiber features a core layer formed by twisting polyester core yarns, strengthening the overall strength of the core layer from the inside. The high density of the polyester core yarns ensures the toughness of the core layer, while the high density of the spandex fiber-formed abrasion-resistant outer layer enhances the overall strength of the abrasion-resistant layer, protecting the core layer from damage. Elastic and strong fibers are spirally intertwined in the abrasion-resistant outer layer to form an elastic layer, further increasing the tightness between the abrasion-resistant outer layer and the core layer, improving the protection of the core layer by the abrasion-resistant outer layer.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 5 A type of sweat-wicking polyester staple fiber includes a core layer 12 and an abrasion-resistant outer layer 7 wrapped around the outside of the core layer 12. Elastic fibers 6 and strong fibers 9 are spirally wrapped around the outside of the abrasion-resistant outer layer 7. The elastic fibers 6 and strong fibers 9 are arranged alternately. Two strands of each elastic fiber 6 and strong fiber 9 are provided to form an elastic layer on the outside of the abrasion-resistant outer layer 7. The core layer 12 is made of six strands of polyester core yarn 8 wound together. Six strands of polyester core yarn 8 are twisted together to form a core layer 12, which strengthens the overall strength of the core layer 12 from the inside. The high tightness between the polyester core yarns 8 ensures the toughness of the core layer 12. The spandex fiber has high elasticity, can be stretched 6 to 7 times, and has a high elastic recovery rate. Its fine linear density forms a high-density abrasion-resistant skin layer 7, which can improve the overall strength of the abrasion-resistant layer, protect the core layer 12 from damage, and has a low moisture absorption rate, which can prevent the core layer 12 from getting damp and causing the polyester core yarn 8 to lose strength due to moisture absorption, thus affecting the dimensional stability of the core layer 12. Furthermore, the elastic fiber 6 and the strong fiber 9 are spirally intertwined in the abrasion-resistant skin layer 7 to form an elastic layer, thereby increasing the tightness between the abrasion-resistant skin layer 7 and the core layer 12 and improving the protection of the core layer 12 by the abrasion-resistant skin layer 7.

[0021] Among them, elastic fiber 6 and strong fiber 9 can be T400 composite fiber and elastic fiber. The elastic layer woven from T400 composite fiber and elastic fiber has wrinkle resistance and dimensional stability, which can prevent the wear-resistant skin layer 7 and core layer 12 from wrinkling and deforming. Bamboo charcoal fiber has a honeycomb-like microporous structure. This unique fiber structure design provides moisture absorption, breathability, and antibacterial properties. The antibacterial fiber bundle includes a base yarn 13 and a first antibacterial yarn 14 and a second antibacterial yarn 15 interlaced around the outside of the base yarn 13. The first antibacterial yarn 14 and the second antibacterial yarn 15 are made of silver ion fiber and copper ion complexed cellulose fiber, respectively. The silver ions in the silver ion fiber react with the sulfur bonds of bacteria, causing protein denaturation and hindering the normal physiological functions of bacteria, thereby achieving antibacterial effects. The copper ions in the copper ion complexed cellulose fiber can come into good contact with the skin, ensuring good antibacterial effects and effectively preventing and treating various skin diseases. Furthermore, the copper ion complexed cellulose fiber has an irregular cross-section, which can increase the contact area between the copper ion complexed cellulose fiber yarn and human skin, thereby improving the antibacterial effect.

[0022] In this embodiment, a protective layer 16 is provided on the outer surface of the blended layer 10; the moisture-wicking layer 11 includes an antibacterial layer 3 woven from antibacterial fiber bundles and a moisture-wicking mesh layer 5 woven from moisture-absorbing fibers. The moisture-wicking mesh layer 5 is woven from bamboo charcoal fiber, and honeycomb-shaped mesh 4 is formed on the moisture-wicking layer 11. The antibacterial fiber bundle includes a base yarn 13 and a first antibacterial yarn 14 and a second antibacterial yarn 15 interlaced around the outside of the base yarn 13. The first antibacterial yarn 14 and the second antibacterial yarn 15 are respectively made of silver ion fiber and copper ion complexed cellulose fiber. A blended layer 10 is provided on the outside of the moisture-wicking layer 11. The blended layer 10 is made of conductive fiber 1 and anti-ultraviolet fiber 2, and the conductive fiber 1 and anti-ultraviolet fiber 2 are interlaced and wrapped around the outside of the moisture-wicking layer 11.

[0023] It should be noted that conductive fiber 1 is made of organic conductive fiber or carbon conductive fiber. These fibers not only have good conductivity, but also have relatively low environmental impact during their production and use. The moisture absorption and breathability of the polyester staple fiber are improved by adding moisture-wicking fibers or using special spinning techniques, such as microporous spinning. High-strength fiber raw materials, such as high-strength polyester fiber or aramid fiber, are used to improve the abrasion resistance and tear resistance of the polyester staple fiber.

[0024] Specifically, the protective layer 16 consists of a waterproof layer 1601 and a fireproof layer 1602. The waterproof layer 1601 and the fireproof layer 1602 are arranged sequentially from the inside out. The waterproof layer 1601 is a polyvinyl chloride waterproof membrane. The outer surface of the protective layer 16 is also provided with a windproof coating, which can prevent the intrusion of external wind and improve the warmth retention of the fabric. Through the setting of the protective layer 16, the polyester staple fiber has waterproof and fireproof functions, thereby improving the durability, comfort and safety of the product, expanding the application fields, enhancing product competitiveness, and promoting technological innovation and industrial upgrading.

[0025] The working principle of the above embodiments is as follows:

[0026] The core layer 12 is formed by twisting polyester core yarns 8 together, which strengthens the overall strength of the core layer 12 from the inside. The high tightness between the polyester core yarns 8 ensures the toughness of the core layer 12. The high density of the abrasion-resistant skin layer 7 formed by spandex fibers can improve the overall strength of the abrasion-resistant skin layer 7 and protect the core layer 12 from damage. Furthermore, the elastic fibers 6 and strong fibers 9 are spirally intertwined with the abrasion-resistant skin layer 7 to form an elastic layer, thereby increasing the tightness between the abrasion-resistant skin layer 7 and the core layer 12 and improving the protection of the core layer 12 by the abrasion-resistant skin layer 7. In addition, the protective layer 16 enables the polyester staple fiber to have waterproof and fireproof functions, thereby improving the durability, comfort and safety of the product, expanding the application fields, enhancing product competitiveness, and promoting technological innovation and industrial upgrading.
