Abstract

The invention relates to the technical field of regenerated cellulose fibers, in particular to a composition and application thereof to preparation of regenerated cellulose fibers with an antibacterial anti-acarien and moldproof function. The composition provided by the invention consists of radix stemonae extract, rhizoma coptidis extract and essential oil of fruit of cubeb litsea tree. The regenerated cellulose fibers comprising the composition can resist bacteria, mites and mold, and also have good mechanical performance, and a textile prepared by using the fibers has good quality.

Description

technical field [0001] The invention relates to the technical field of regenerated cellulose fibers, in particular to a method for preparing regenerated cellulose fibers with antibacterial, anti-mite and anti-mildew properties by using extracts of basilica extracts, extracts of coptis chinensis and litsea cubeba essential oil as raw materials. Background technique [0002] Bacteria and mold widely exist in nature, and people inevitably come into contact with various bacteria, fungi and other microorganisms in life. Among them, bacteria are a class of prokaryotic microorganisms, which are short in shape and simple in structure, and mostly reproduce by binary fission. Fungi are eukaryotic organisms, which are heterotrophic organisms with a nucleus. Mold is a general term for some filamentous fungi. These microorganisms will grow and multiply rapidly under suitable environmental conditions, and spread diseases and affect human health through contact. [0003] Acarid belongs t...
