Abstract

The invention provides a sheath-core natural antibacterial healthcare ultraviolet-proof polypropylene fiber. The sheath-core natural antibacterial healthcare ultraviolet-proof polypropylene fiber comprises a core layer and a sheath layer, wherein the core layer is completely wrapped by the sheath layer and is not exposed; the component of the sheath layer is polypropylene; the component of the core layer is a mixture of plant extracts and polypropylene, the weight of the plant extracts accounts for 35-65% of the total weight of the core layer component, the weight of the polypropylene accounts for 35-65% of the total weight of the core layer component; the weight ratio of the sheath layer component to the core layer component is (70-35): (30-65). Therefore, the sheath-core natural antibacterial healthcare ultraviolet-proof polypropylene fiber has the advantages that the plant extracts can be effectively prevented from being lost in storage and processing processes, the polypropylene fiber has high antibacterial efficiency, strong transdermal absorption capacity and good skin affinity, when the polypropylene fiber is in direct contact with the skin of a human body, the polypropylene fiber is antibacterial and ultraviolet-proof and meanwhile releases nutritional ingredients to be adsorbed by the skin, the perfect combination among the fiber, skin care, body building, life cultivation and health preservation is realized, and by using the polypropylene fiber, the human body can obtain more health benefits. Waste resources are recycled; the sheath-core natural antibacterial healthcare ultraviolet-proof polypropylene fiber has enormous social, ecological, environmental and economic benefits.

Description

technical field [0001] The invention belongs to the field of polypropylene fibers, in particular to a skin-core type 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, i...
