preparation example Construction

[0026] The invention provides a kind of preparation method of modified animal fluff fiber, comprises the following steps:

[0027] Degreasing and plasma-treating animal hair fibers to obtain pretreated animal hair fibers;

[0028] Under the condition of cross-linking agent, immerse the pretreated animal hair fiber in the glacial acetic acid aqueous solution of biomass, and carry out cross-linking treatment to obtain biomass modified animal hair fiber; the biomass is chitin and / or chitosan sugar;

[0029] Under the condition of an enzyme initiator, immerse the biomass-modified animal hair fiber in a tea polyphenol solution, perform oxidation polymerization-adsorption treatment, and obtain a tea polyphenol-biomass modified animal hair fiber;

[0030] The tea polyphenol-biomass modified animal hair fiber is immersed in a metal ion solution, and a chelation reaction is carried out to obtain the modified animal hair fiber; the polymetallic ions in the metal ion are copper ions and...

Embodiment 1

[0065] Wash cashmere with 15% ethanol aqueous solution at 40°C for 25 minutes for degreasing, deionize after washing with deionized water, and obtain degreased cashmere with a moisture content of 70%; use air as the plasma gas, under 60W, 30Pa Perform plasma treatment for 180s to obtain pretreated animal hair fibers;

[0066] Under the condition of stirring at 40°C and 500rpm, mix chitin with 0.5% glacial acetic acid aqueous solution to obtain 2% chitin glacial acetic acid aqueous solution; add to the obtained chitin glacial acetic acid aqueous solution Citric acid and sodium polyphosphate, obtain biomass-crosslinking agent mixed solution, the massfraction of citric acid in the biomass-crosslinking agent mixed solution is 0.05%, the massfraction of sodium polyphosphate is 0.5%; According to bath ratio The ratio is 1:40.

Abstract

The invention belongs to the technical field of textile fibers, and particularly relates to a modified animal villus fiber and a preparation method thereof. According to the modified animal villus fiber and the preparation method thereof provided by the invention, an animal villus fiber, biomass, tea polyphenols and metal ions, namely copper ions and / or zinc ions are used as raw materials, and plasma treatment and crosslinking treatment, oxidative polymerization-adsorption treatment and chelation reaction which are sequentially carried out subsequently are combined, so that the surface treatment etching degree of the animal villus fibers is increased, the cross-linking, adsorption and metal ion chelation strength of modified substances is improved, the structural stability of the modified animal villus fiber is remarkably improved while the animal villus fiber is endowed with antibacterial, mildew-proof and antiviral functions, and the antibacterial, mildew-proof and antiviral durability of the modified animal villus fiber is improved.

Description

technical field [0001] The invention belongs to the technical field of textile fibers, and in particular relates to a modified animal hair fiber and a preparation method thereof. Background technique [0002] Animal down fiber has the characteristics of softness, slenderness, fineness and smoothness, good thermal performance and good comfort. It is a high-grade textile raw material in textile fibers and is deeply loved by consumers. However, animal fluff fiber itself is a natural protein fiber, which is easy to be eaten by moths, and is also vulnerable to erosion by bacteria and molds, which may cause the spread of diseases and the deterioration of fiber performance. [0003] At present, there are many antibacterial finishing methods for animal hair fibers, such as the use of antibacterial additives such as heavy metals, chitin, lysozyme, quaternary ammonium salt organic antibacterial agents or plant extracts, as well as surface impregnation, surface nanocrystallization, Fi...
