Abstract

The production process of viscose filament with nanometer chitin includes the steps of mixing, grinding, filtering, injecting, acid bath treatment, forming, washing and stoving. It features the mixing step to compound chitin solution with chitin, desalted water and assistant; and the injecting step comprising suction filtering the chitin solution and adding the chitin solution into raw spinning liquor with the adding ratio being 20 ml to 1L. The viscose fiber with nanometer chitin of the present invention has tightly combined chitin, and lasting and stable chitin function. The present invention expands the application range of viscose product.

Description

technical field [0001] The invention relates to the production technology of antibacterial viscose filament fiber, in particular to a production method of nano chitin viscose filament with chitin antibacterial function. Background technique [0002] Chitin, also known as crab shellin and chitin, is a natural polymer substance containing amino polysaccharides. Its chemical name is (1-4)-2-acetamido-2-deoxy-β-D-glucose. Or referred to as polyacetamide-based glucose. It not only exists in the shells of shrimps and crabs, but also widely exists in the cell walls of mushrooms, fungus, algae, shellfish, cartilage, cartilage and epidermis of animals (such as squid and cuttlefish), arthropods (insects) and fungi. Different from non-renewable resources such as coal and petroleum, the annual biosynthesis of chitin is more than 10 billion tons, and it is the second largest organic renewable resource on the earth after cellulose. [0003] In terms of structure, the chemical structure ...
