Efficient tea dyeing method

Abstract

The invention relates to an efficient tea dyeing method. The efficient tea dyeing method comprises the following steps: 1) drying tea raw material till water content below 7%, and then smashing into 300-800 mesh ultrafine tea powder; 2) adding water into the tea powder and uniformly mixing tea powder and water at ratio of 1:(50-80); placing a mixed solution in an ultrasonoscope for preparing a dyeliquor under the conditions of frequency of 50-80 KHz, time of 40-60min and temperature at 70-80 DEG C; cooling and filtering the mixed solution after ultrasonic treatment, thereby acquiring a tea dye liquor; 3) adding 1-3%wt acid solution into the tea dye liquor till PH value of the tea dye liquor is 3.5-4.5; 4) putting a to-be-dyed fabric into the tea dye liquor at liquor ratio of 1:(40-50), and placing into the ultrasonoscope under the conditions of frequency of 50-80 KHz, time of 5-10min and temperature at 70-80 DEG C; 5) taking the ultrasonically soaked fabric from the tea dye liquor, performing microwave drying dyeing under the conditions of power of 0.1-5W/g and time of 1-3min, and then performing far infrared dry fixation for 1-3min under the conditions of power of 500-800W and temperature at 60-80 DEG C. The efficient tea dyeing method has the advantages of natural and environment-friendly properties, energy-efficient property and high color fastness.

Description

technical field [0001] The invention relates to the technical field of fabric dyeing, in particular to an efficient, green, and chemical-residue-free fabric tea-dyeing method. Background technique [0002] In recent years, with the enhancement of people's awareness of environmental protection and health, people have gradually realized that chemical dyes are harmful to human health and the environment, and the use of plant dyes has gradually become a popular trend. [0003] Tea leaves are not only rich in nutrients, but also contain various health-care ingredients such as tea polyphenols, tea polysaccharides, and tea pigments. In addition, tea leaves have a unique fragrance. Therefore, using tea leaves for dyeing can not only make fabrics green Natural and environmentally friendly, its smell can also refresh people's minds, and can repel insects and prevent moths. It also has the functions of anti-ultraviolet and skin protection. [0004] At present, the preparation of tea d...

AI Technical Summary

Problems solved by technology

[0004] At present, the preparation of tea dyeing solution is mainly by boiling fresh tea leaves or dry tea in water, but the dissolution of tea pigment in this traditional method is limited, and the pigment in tea cannot be fully utilized, which will cause waste of resources

At the same time, the traditional tea dyeing method takes a long time, consumes energy, and the color fixing rate is not high, and the color fastness is poor. Most of the mordants used to improve the coloring effect are mainly metal compounds, which are likely to cause residues that are harmful to human health. , the dyeing process will also cause harm to the environment
