Environmentally friendly viscose fiber is a fiber material that focuses on environmental friendliness and sustainability, and has positive significance for promoting sustainable development and reducing the impact on the environment.

[0003] However, the existing environmentally friendly viscose fibers have poor wear resistance, which will reduce the durability and stability of environmentally friendly viscose fiber products such as textiles, clothing, household items, etc. during use. The performance in actual applications is poor and does not conform to the concept of sustainable development.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1-2 , the utility model provides the embodiment:

[0019] The embodiment of the present application discloses a wear-resistant and environmentally friendly viscose fiber, comprising a first viscose fiber matrix 1, a second viscose fiber matrix 2 and a wear-resistant layer 3. The surfaces of the first viscose fiber matrix 1 and the second viscose fiber matrix 2 are both provided with a reinforcement layer. The first viscose fiber matrix 1 and the second viscose fiber matrix 2 are both located in the inner cavity of the wear-resistant layer 3. The surfaces of the first viscose fiber matrix 1 and the second viscose fiber matrix 2 are both adhered to the inner wall of the inner cavity of the wear-resistant layer 3. The wear-resistant layer 3 is composed of a spandex layer 4, a polypropylene layer 5 and a polyurethane coating 6. The spandex layer 4 and the polypropylene layer 5 are respectively a spandex film and a polypropylene film. The spandex film and the polypropylene film are bonded by hot pressing composite technology. The polyurethane coating 6 is respectively coated on the surfaces of the spandex layer 4 and the polypropylene layer 5.

[0020] As a technical optimization scheme of the utility model, spandex and polypropylene are processed into films of uniform size and thickness respectively, and then hot pressing composite technology is used to bond them together through high temperature and pressure, so as to ensure that the two fibers are well combined to form a composite material. Finally, a polyurethane coating 6 is coated on the surface of the spandex layer 4 and the polypropylene layer 5. In this way, the strength and softness of spandex and polypropylene are combined while the polyurethane coating 6 provides additional wear resistance. This combination can make the viscose fiber have better wear resistance, softness and comfort, and is suitable for application fields that require durability and comfort.

[0021] The reinforcement layer is aramid fiber, and the aramid fiber is evenly distributed on the surface of the first viscose fiber matrix 1 and the second viscose fiber matrix 2.

[0022] As a technical optimization scheme of the utility model, aramid fiber has very high tensile strength, wear resistance and heat resistance, and by adding aramid (such as polyterephthalamide) fiber, the wear resistance of the cloth can be significantly improved, which can effectively prevent the damage of the cloth during friction and wear and extend the service life of the cloth.

[0023] The first viscose fiber matrix 1 and the second viscose fiber matrix 2 are connected by thread winding.

[0024] As a technical optimization scheme of the utility model, the threaded winding connection method can effectively combine the viscose fibers tightly together to form a more solid structure. This connection method can increase the friction between the fibers and prevent the fibers from being detached or damaged due to external forces during use, thereby improving wear resistance. In addition, threaded winding can also increase the contact area between the fibers and improve the stability and durability of the connection.

[0025] Working principle: By forming the wear-resistant layer 3 with a spandex layer 4, a polypropylene layer 5 and a polyurethane coating 6, the overall performance of the viscose fiber can be improved, which is beneficial to improving its performance in practical applications, conforming to the concept of sustainable development, and also meeting consumers' demands for product quality and environmental performance. By arranging aramid fibers on the surface of the first viscose fiber matrix 1 and the second viscose fiber matrix 2, and by threading the first viscose fiber matrix 1 and the second viscose fiber matrix 2 together, additional support and wear resistance can be provided to the viscose fiber, and the bonding strength of the viscose fiber can be increased, thereby improving the wear resistance of the overall material.
