Problems solved by technology

However, because there are a large number of inorganic ions in the sea mud layer, it shows hydrophilic and oleophobic properties, and the spacing is small, making it difficult to insert organic macromolecular chains, and its application range is greatly limited.
After searching, sea mud-loaded plant extracts and polypropylene resin are blended and melt-spun to make polypropylene fibers with bactericidal and mosquito-repelling functions. So far, there have been no literature reports or patent publications.

Abstract

The invention provides a sea mud/plant composite sterilization and mosquito repellent polypropylene fiber and a preparation method thereof. It is made of the following components by weight: 65-98% of polypropylene resin, 1-30% of sterilization and mosquito-repellent masterbatch , camphor leaf oil 0.5-3%, heptyl octanoate 0.3-0.7%, carnosic acid 0.2-1.3%; the sterilization and mosquito repellent masterbatch is made from the following raw materials by weight: 70-92 parts of polypropylene resin, 4.6-17 parts of sea mud powder, 2-6.5 parts of frangipani extract, 1.3-5 parts of Artemisia annua extract, and 0.1-1.5 parts of coupling agent. The above-mentioned raw materials are processed, blended, and melt-spun into polypropylene fibers through various methods, which are rich in aroma, skin-friendly, safe and washable. They not only have good mosquito repellent effect and long-lasting effect, but also provide excellent sterilization. And skin care and health care effects, comprehensively improve skin self-defense ability, and show good spinnability, hygroscopicity, air permeability, dyeing uniformity and mechanical properties, high fiber strength and excellent wearing performance.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a sea mud / plant composite bactericidal and mosquito-repelling polypropylene fiber and a preparation method thereof. Background technique [0002] Polypropylene fiber, also known as PP fiber or polypropylene fiber. It is a synthetic fiber spun from isotactic polypropylene obtained by propylene polymerization. Because of its simple production process, low price, light relative density, high strength, corrosion resistance, mildew resistance, good resilience, and good fabric effect, it is unique in the application of textiles that live with the human body day and night. It is used to make underwear , Swimming suits, socks, bed sheets and other textiles in contact with the body and one of the best fibers for medical and sanitary nonwovens. However, polypropylene fiber also has certain defects, such as not easy to dye, poor hygroscopicity, air permeability and drapability, etc. In ...
