Nature antibacterial health-care ultraviolet-proofing polypropylene fiber

Abstract

The invention provides an antibacterial health-care ultraviolet-proofing polypropylene fiber. The fiber is prepared by mixing the following components in percentage by weight: 1.5-10 percent of a green plum branch and leaf extract, 1-8 percent of a pomegranate bark extract, 60-85 percent of polypropylene slices and the balance of auxiliaries through fusing, granulating, re-fusing and spinning. Therefore, the bioactivators and nutrients existing in a compound mode of the green plum branch and leaf and pomegranate bark extract components are uniformly contained in the surface layer of and inside of the fiber, various textiles which are produced by the fiber and in contact with human skins are good in skin compatibility and strong in transdermal absorption capability, can be directly in contact with human skins, can play antibacterial and ultraviolet-proofing effects on a human body, can sustainably release the nutrients which can be absorbed by skin, realizes perfect combination of fiber and skin-caring and body-building, life cultivation and health care, and is advantageous to a human body to obtain more health benefits. Furthermore, waste resources can be recycled, so that huge social, ecological, environmental and economical benefits are implied in the fiber.

Description

technical field

[0001] The invention belongs to the field of polypropylene fiber, in particular to a natural antibacterial health care and anti-ultraviolet polypropylene fiber. Background technique

[0002] Polypropylene fiber (polypropylene fiber), commonly known as polypropylene, is a fiber made of propylene as a raw material through polymerization and melt spinning. Because of its rich source of raw materials, low price, simple production process, light weight and softness, and excellent properties such as moisture-wicking, sweat-wicking, heat-retaining, mildew-proof and moth-proof, it is widely used in clothing, decoration and industrial products, especially It is easy to blend with natural fibers or chemical fibers into woven and knitted fabrics, very suitable for making underwear, T-shirts, socks, bed sheets and other textiles that are in direct contact with human skin. However, because polypropylene fiber itself does not have antibacterial function, it is easy to be ...
