Background technique

In recent years, with the improvement of people's living standards, people are more particular about clothing requirements. While paying attention to novel styles, they also pay more and more attention to the comfort and functionality of clothes. The rapid development of modern industry, the birth of various new technologies, new processes, and new materials have provided the possibility for people to pursue a more comprehensive concept of clothing. The current popular trend is to pursue a natural, simple and healthy lifestyle. However, with the improvement of material living standards, people's requirements for textiles are no longer limited to the original basic characteristics such as warmth and comfort, but pay more attention to health, fashion, beauty and some special functions, and pursue the original ecological quality. , Fashion beauty.

Seashell fiber is a functional fiber with antibacterial and skin care functions. Its antibacterial properties come from chitin in seashells. Seashell fiber is a viscose-based fiber made from chitin in seashell shells. It is safe and healthy to use. It has special properties of bioactivity, biodegradability, biocompatibility, non-toxicity, and low immune antigenicity. It has excellent performance, soft hand feeling and no irritation to the human body. It has broad development prospects in the application and development of health care clothing. However, the wet breaking strength is small, and the fabric made of pure seashell fiber has a large shrinkage deformation.

PTT fiber is a polyester fiber with excellent performance, good antifouling performance, soft hand feeling, good elasticity, high elastic recovery rate, good heat setting, high elongation at break, good dyeability, good dryness, and soft hand feeling , good bulkiness and small initial modulus. However, PTT fiber has poor water absorption and prominent electrostatic phenomena, which makes it difficult to form a net and have many yarn hairiness in the spinning process of pure PTT fiber, and the processed fabric has no health care function.

Wool fiber has fine fineness, good elasticity, good fullness, good warmth retention, fine and smooth handle, soft luster, good fluffiness, good hygroscopicity, and good comfort, but it has no health care function.
