Problems solved by technology

However, due to the large amount of inorganic ions in the sea mud layer, it exhibits hydrophilic and oleophobic properties, and the small spacing makes it difficult to insert organic macromolecular chains, thus limiting its large-scale industrial application.
After searching, no report has been found so far that sea mud-loaded plant extracts and polypropylene resins are blended and melt-spun to make antibacterial and UV-resistant polypropylene fibers

Abstract

The invention provides antibacterial and anti-ultraviolet sea mud polypropylene fibers and a preparation method thereof. The antibacterial and anti-ultraviolet sea mud polypropylene fibers are prepared from the following components in percentage by weight: 65 to 98 percent of polypropylene resin, 1.5 to 30 percent of antibacterial and anti-ultraviolet master batches, 0.4 to 3.5 percent of sea asparagus oil, and 0.1 to 1.5 percent of tocopheryl acetate, wherein the antibacterial and anti-ultraviolet master batches are prepared from the following raw materials in parts by weight: 70 to 90 parts of polypropylene resin, 6 to 20 parts of sea mud powder, 2 to 5 parts of an Altay eremurus root extract, 1.5 to 3 parts of a locust flower extract and 0.5 to 2 parts of a coupling agent. The polypropylene fibers prepared from all the raw materials by various processing measures and reasonable mixing smell good, are high in skin friendliness, have good antibacterial and anti-ultraviolet effects and long action time, and can release nutritional substances, so that more healthy benefits can be brought to a human body; furthermore, the antibacterial and anti-ultraviolet sea mud polypropylene fibers are high in spinnability and mechanical property; the moisture absorption breathability, the dyeing uniformity and the antistatic property of the fibers are obviously improved, and the application range of sea mud is greatly expanded.

Description

Technical field [0001] The invention relates to the technical field of textiles, in particular to a sea mud antibacterial and UV-proof polypropylene fiber and a preparation method thereof. Background technique [0002] Polypropylene fiber is also called 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 product 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 that are in personal contact with the human body and one of the best fibers for medical and health non-woven fabrics. However, polypropylene fiber also has certain defects, such as difficult to dye, poor moisture absorption, air permeability and drape, ...
