Problems solved by technology

This dyeing and finishing washing process is mainly used in the continuous washing of woven fabrics dyed with chemical dyes, and it is single-frequency ultrasonic washing. It cannot be used in the intermittent dip-dyeing soaping process of short-thread fibers dyed with natural Chinese herbal plant dyes.
[0005] At present, the use of ultrasonic waves for fabric dyeing is single-frequency ultrasonic waves. Since different types of fabrics are matched with d

Abstract

The invention belongs to the field of textile printing and dyeing and particularly relates to a method for low-temperature ultrasonic dyeing and soaping of short fiber by using a Chinese herbal medicine plant dye. The method is characterized in that, during the dyeing and the soaping processes, two types and more than two types of ultrasonic waves with different frequencies are combined for assistance, wherein during the dyeing process, the frequency selection range of the ultrasonic waves is 20KHz-28KHz, the dyeing temperature is 15 DEG C-35 DEG C, the dyeing treatment time is 10-60min, and the total intensity of the multi-frequency ultrasonic waves is 0.1-0.8W/cm<2>; and during the soaping process, the frequency selection range of the ultrasonic waves is 28KHz-55KHz, the soaping temperature is 20 DEG C-35 DEG C, the soaping time is 5-30min, and the total intensity of the multi-frequency ultrasonic waves is 0.2-1W/cm<2>. Compared with the prior art, the mehtod disclosed by the invention has the advantages that, under the low-temperature condition, the ultrasonic wave effects can be improved over one time in comparison with the single-frequency ultrasonic waves, the high-temperature damages can be avoided, and the uniform dyeing property of dyeing of the natural dye can be improved.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing, and in particular relates to a low-temperature sonic dyeing and soaping method of Chinese herbal medicine plant dyes for short fibers. Background technique [0002] At present, in the textile printing and dyeing industry, chemical dyes such as reactive dyes and direct dyes are mainly used for fibers such as hemp and viscose, which have the disadvantages of large pollution and high energy consumption in the dyeing process; while the dyeing process of natural vegetable dyes is environmentally friendly, but there are disadvantages. Due to the defects of low color rate, poor level dyeing property and poor color fastness, large-scale mass production has not been achieved in the textile industry. [0003] Using ultrasonic waves in the textile printing and dyeing industry can improve the rubbing fastness and soaping fastness of fabrics, as the patent document with publication number CN20101054...
