Abstract

The invention provides multifunctional vegetable regenerated cellulose fibers and a preparation method thereof, belongs to the technical field of functional regenerated cellulose fibers, and can solvethe problems that an existing functional regenerated cellulose fiber is single in function or multifunctional, is poor in functionality, complex in preparation process, difficult in industrial production and the like. The multifunctional vegetable regenerated cellulose fibers comprise the following components in percentages by weight: 3.0-8.0wt% of a sweet basil extract and 1.72-5.22wt% of complex plant essential oil, wherein the complex plant essential oil comprises 0.69-2.09wt% of mint oil, 0.69-2.09wt% of folium artemisiae argyi essential oil and 0.34-1.04wt% of lavender essential oil. Thepreparation method disclosed by the invention can be applied to preparation of multifunctional vegetable regenerated cellulose fibers integrating functions of antibiosis, mosquito repelling, skin protection and the like, and is further applied to textiles prepared from the multifunctional vegetable regenerated cellulose fibers.

Description

technical field [0001] The invention belongs to the technical field of functional cellulose fibers, and in particular relates to a multifunctional antibacterial and mosquito repelling fiber prepared from cellulose pulp, sweet basil extract, peppermint essential oil, mugwort essential oil and lavender essential oil as raw materials. Vegetable regenerated cellulose fiber and its preparation method. Background technique [0002] In real life, people will inevitably come into contact with various bacteria, fungi and other microorganisms, and textiles are a good place for these microorganisms to live and a source of disease transmission. Mosquitoes are one of the "four pests" and the main insects that threaten public health. They have many types, reproduce quickly, and are widely distributed, and can transmit various diseases. As people pay more and more attention to health, more and more functional fibers and their textiles are constantly coming out, and functional regenerated ...
