Problems solved by technology

Bacteriostatic agents do not contribute to the strength of UHMWPE fibers, and adding a large amount of bacteriostatic agents will lead to a significant decline in the performance of UHMWPE fibers; however, bacteriostatic agents or large-sized particles produced by agglomeration will become defective structures of fibers, reducing fiber performance more quickly

Abstract

The invention provides an antibacterial mother liquor for producing antibacterial ultrahigh-molecular-weight polyethylene fiber. The antibacterial mother liquor for producing the antibacterial ultrahigh-molecular-weight polyethylene fiber is composed of, by weight part, 10-30 parts of antibacterial polymers, 70-90 parts of solvent, 0-3 parts of surfactant, 0-1 part of dispersant and 0.3-5 parts ofbulking agent.

Description

technical field [0001] The invention relates to ultra-high molecular weight polyethylene fibers, in particular to the application of antibacterial polymers and the production of ultra-high molecular weight polyethylene fibers with antibacterial function. Background technique [0002] Ultra-high molecular weight polyethylene (UHMWPE) fibers have the characteristics of high strength, high modulus, and high thermal conductivity, and are irreplaceable in many fields. It is pioneering to produce a UHMWPE fiber with antibacterial function, which can enrich the performance and function of UHMWPE fiber and expand the application of UHMWPE fiber in civil fabrics, medical equipment and other fields. [0003] However, the difficulty in producing UHMWPE fibers with antibacterial function lies in: UHMWPE fibers have low surface energy and surface tension, high crystallinity, and extremely smooth surface, and it is difficult to effectively combine with commonly used inorganic and organic ...
