Problems solved by technology

The method of the invention has the advantages of simple operation, high efficiency, and long-lasting effect, but it also has obvious shortcomings. For example, in order to achieve a higher antibacterial rate, the amount of copper in the mesoporous zirconium phosphate is relatively large. 0.5~7.6%, so its cost is higher

Abstract

The present invention relates to the field of fiber manufacturing, in particular to a copper ion antibacterial fiber and an antibacterial fabric. The fiber includes the following components in parts by weight: 100 parts of polylactic acid slices, 5~ 15 parts, 5-10 parts of hydrophobically modified polyvinyl alcohol, 1-5 parts of silane-capped polyethylene glycol, 1-3 parts of cross-linking agent, 0.01-0.05 parts of initiator and 0-3 parts of functional additives; The amount of copper loaded in the copper-loaded nano borosilicate ceramic powder is 0.01-0.1 wt%. The present invention overcomes the defect that antibacterial polylactic acid fibers in the prior art need to add more antibacterial agents in order to achieve a higher antibacterial effect, and the present invention combines copper particles with nanoporous phosphorus-containing borosilicate having far-infrared emission capabilities The combination of ceramic powder makes it possible to achieve effective antibacterial effect under the premise of extremely low copper particle loading, and the copper ion antibacterial fiber prepared by the present invention has good mechanical properties and water washing resistance, so it can be effectively applied in the field of medical care.

Description

technical field [0001] The invention relates to the field of fiber manufacturing, in particular to a copper ion antibacterial fiber and an antibacterial fabric. Background technique [0002] Polylactic acid fiber is made from starch-containing agricultural products such as corn, wheat, and sugar beet. After fermentation to generate lactic acid, it is made by polycondensation and melt spinning. It can be decomposed into carbon dioxide and water by microorganisms in soil or seawater. When burned, it will not emit poisonous gas and cause pollution. It is a sustainable ecological fiber. The fabric has good handle and drapability, anti-ultraviolet radiation, low flammability and excellent processing performance. It is suitable for various fashion, casual wear, sporting goods and sanitary products, etc., and has broad application prospects. [0003] Existing polylactic acid fibers usually do not have antibacterial effect, and in order to make polylactic acid fiber have antibacter...
