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 present 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-mold properties by using Stemonium extract, Coptis extract and Litsea cubeba essential oil as raw materials. Background technique [0002] Bacteria and molds are widely found in nature. In life, people will inevitably come into contact with various bacteria, fungi and other microorganisms. Among them, bacteria are a type of prokaryotic microorganisms, with short and thin shapes, simple structures, and most of them reproduce in a two-division manner. A fungus is a eukaryote, a heterotrophic organism with a nucleus. Mold is a general term for some filamentous fungi. These microorganisms can grow and reproduce rapidly under suitable environmental conditions, and spread diseases and affect human health through contact. [0003] Mites belong to a class of tiny animals in ...
