Abstract

The invention discloses a preparation method of a tea dyed costume fabric. By the use of fatty alcohol-polyoxyethylene ether, sodium citrate, hydroxypropyl methylcellulose, ethyl maltol and 2-hydracrylic acid, permeation of water is accelerated, so that tea polyphenol can quickly enter water, and the extraction time is shortened; 2-phosphonic acid butane-1,2,4-tricarboxylic acid sodium salt, sodium tetraphenylboron, 1,2,3,4,5,6-cyclohexanehexacarboxylic acid, sorbitol, ethanediol di(2-aminoethyl ether)quadrol enhance tea even dyeing, so that the dyeing is uniform and consistent, and the resistance to wet rubbing fastness of tea leaves is improved; hydroxypropyl guar gum trimethyl ammonium chloride, trehalose, glucosamine sulfate, 2,4,6-trichlorine benzoic acid and 4-hydroxy phenethylamine enhance the antibacterial property of chitosan, and the dyeing firmness is facilitated; ethylene diamine tetraacetic acid, L-cysteine, 4-hydroxyphenyl boronic acid, methoxyphenylboronic acid and hexamethylol melamine enhance the fixation effect of a tea dye, and the color fastness is enhanced; the costume fabric has high resistance to washing fastness, antibacterial property and resistance to dry and wet rubbing fastness.

Description

technical field [0001] The invention relates to a method for preparing tea-dyed clothing fabrics, in particular to a method for preparing tea-dyed clothing fabrics with dry and wet wiping resistance, water washing resistance and good color fastness. Background technique [0002] China is the earliest country in the world to grow, manufacture and drink tea, and its tea plantation area and output rank first in the world. Tea polyphenols, a physiologically active substance rich in tea, account for about 20-35% of its dry weight. Its main component, catechin, is easily oxidized to have the functions of scavenging free radicals, anti-oxidation, anti-mutation, antibacterial and antiviral, etc. Physiological functions of tea pigment. However, it is rare to develop tea pigment products at home and abroad at present, and deep-processing products developed with fresh tea leaves as raw materials are even rarer. [0003] Tea dyeing is a kind of plant dyeing process. Tea dyeing and pl...
