Abstract

The invention provides sea mud/plant composite bacteria inhibiting and whitening polypropylene fibers and a preparation method thereof. The polypropylene fibers are prepared from the following components by weight percent: 70-98% of polypropylene resin, 1-25% of bacteria inhibiting and whitening master batch, 0.8-3% of cerasus humilis kernel, 0.1-1.5% of magnesium ascorbyl phosphate and 0.1-0.5% of di-iso-octyldiphenylamine, wherein the bacteria inhibiting and whitening master batch comprises the following raw materials by weight percent: 65-90% of polypropylene resin, 5.9-25% of sea mud powder, 2.5-5% of anchusa italica extract, 1.5-3.5% of extract of root of wintersweet and 0.1-1.5% of coupling agent. The polypropylene fibers prepared by reasonably compounding the raw materials by various processing means have fragrant smell, good skin affinity, hygroscopicity, spinnability and dyeing property and high fiber forming strength, not only have a wide antibacterial spectrum, good antibacterial effects and lasting effects but also show the effect of inhibiting skin pigmentation and the effects of whitening and beautifying and conduce to improving human health when frequently coming into contact with the skins of human bodies.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a sea mud / plant composite antibacterial and whitening 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 , swimwear, socks, bed sheets and other textiles that are in close contact with the human 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, et...
