Abstract

The invention discloses biologically modified antibacterial hemp fiber and a preparation method thereof. The biologically modified antibacterial hemp fiber is prepared from raw materials in parts by weight as follows: 70-80 parts of hemp fiber, 5-10 parts of a microbial modifier and 0.1-3 parts of antibacterial components; the microbial modifier contains acidothermus, micromonospora and acetobacter xylinus; the antibacterial components are selected from one or more of subtilin, polymyxin E, gramicidin S and bacitracin. The biologically modified antibacterial hemp fiber is prepared from the antibacterial components and the hemp fiber through biochemical reaction of microorganisms and obtained by bonding connection of a large quantity of active groups, more antibacterial components are in bonding connection to the biologically modified antibacterial hemp fiber, and the biologically modified antibacterial hemp fiber is good in mechanical property and can be applied to every field of textiles and consumes.

Description

technical field [0001] The invention relates to the technical field of textile products, in particular to a biomodified antibacterial hemp fiber and a preparation method thereof. Background technique [0002] Hemp fiber is cellulose fiber, the basic chemical composition is cellulose, the content is about 75%, and other non-fibrous substances such as pectin, hemicellulose, lignin, fat wax. Cellulose is a natural polymer compound. The chemical structure of cellulose is composed of α-glucose as the basic structural unit, and its elemental composition is 44.44% carbon, 6.17% hydrogen, and 49.39% oxygen. The degree of polymerization of ramie fiber is between 2000 and 2500. Because hemp fiber is a natural material, its fabric has no stimulation and no side effects when in contact with the skin. Long-term wear is beneficial and harmless to the human body. The thermal conductivity is small so that the fabric has better thermal performance; the dyeing performance of the linen is go...
