Preparation method of multifunctional yarn containing silver fibers

Abstract

The invention provides a preparation method of a multifunctional yarn containing silver fibers. The multifunctional yarn containing silver fibers is prepared by the following fiber materials by weight percent: 8-15% of nano silver fibers, 10-20% of nano carbon fiber and the balance of other fibers, wherein the other fibers refer to any one or more of Tencel fibers, modal fibers, outlast, moisture absorption fibers and fine denier fibers; the nano silver fiber is prepared by adding nano silver the weight ratio of which is 0.2-2% and the particle size of which is 18-150nm in a polypropylene solution and interlacing into a net structure through a multipoint high pressure jet mode, and the monofilament length of the nano silver fiber is 20-30mm; the monofilament length of the nano carbon fiber is 25-35mm, and the nano carbon content thereof is 1-3%; and the other fibers are discontinuous short fibers. By special treatment and collocation of raw materials as well as adjustment and improvement of the preparation method, the requirements of the existing production equipment for producing top grade textiles can be met.

Description

technical field [0001] The invention relates to the technical field of novel spinning materials, in particular to a method for preparing composite functional yarns containing silver fibers. Background technique [0002] The functionality of textiles is to meet people's requirements for protection, health care and comfort. Various technologies are adopted to endow textiles with functions such as antibacterial, anti-ultraviolet radiation, anti-radiation, flame retardant, anti-static, negative ion release, and far-infrared emission. The combination of functionality and comfort and the compounding of multiple functions are the development direction of textiles. Metal-coated fibers cover the surface of the fiber substrate with metal in a molecular or atomic state. Commonly used metals include copper, nickel, silver, etc., but both nickel-plated fibers and copper-plated fibers have defects to varying degrees. Silver fiber has good performance, and its fabric function is safe and ...

AI Technical Summary

Problems solved by technology

[0003] Silver fiber has many good functions, but at present, the development of silver fiber textile products is mostly in the interweaving of filaments. The reason is that the technical difficulties in the short fiber spinning process have not been solved, especially in the selection and mixing of blended raw materials However, the determination, carding, mixing, etc. of the ratio have not been able to solve the technical difficulties systematically and completely. Even if some short-fiber yarns have been developed, it is difficult to meet the needs in terms of quality and function.

[0004] In addition, the current silver fiber mainly adopts the monofilament structure of the coating process, which has the advantage of fully exerting the conductivity and bactericidal properties, but the outstanding problem is that during the textile processing and product use, due to friction, repeated stretching, etc. Mechanical action, the integrity of the silver layer will be damaged to varying degrees, and the degree of bonding with other fibers is poor, resulting in problems such as short service life and serious functional degradation of products made of yarn
