Abstract

The invention discloses application of a wormwood natural dye in modal underwear dyeing, and belongs to the technical field of textile coatings. A method comprises the following steps: cleaning wormwood, air-drying and crushing; putting the obtained wormwood powder into an ethanol aqueous solution for soaking, and filtering; ultrasonically extracting an obtained dye initial solution; adding an obtained dye secondary filtrate into a pentanediol solution, centrifuging and separating; mixing an obtained yellow pigment liquid with anhydrous sodium sulfite and the like according to a certain proportion; putting modal yarn and fabric into deionized water to be modified; putting the modified modal yarns and the fabric into an obtained treating fluid for reaction and soaking; and taking out the modal yarn and the fabric, cleaning and drying. According to the application of the wormwood natural dye in modal underwear dyeing, the application process of the wormwood natural dye in modal underweardyeing is simple, the reaction time is short, the efficiency is high, and the prepared modal underwear has the effects of naturally inhibiting bacteria, warming and activating meridians, promoting qito activate blood, clearing damp and expelling cold, diminishing swelling and resolving masses and the like, and is friendly to the environment.

Description

technical field [0001] The invention belongs to the technical field of textile coatings, and more specifically relates to the application of wormwood natural dyes in the dyeing of modal underwear. Background technique [0002] With the gradual enhancement of people's awareness of ecological environmental protection and their own health, more and more consumers prefer green and environmentally friendly textiles, and natural dyes are increasingly attracting people's attention. Fabrics dyed with natural dyes not only meet the production needs of environmental protection and ecology, but also avoid the damage to human health caused by synthetic dyes, and meet the requirements of healthy and functional clothing. [0003] Modal fiber is the second generation of regenerated cellulose fiber. This fiber combines the comfort of natural fiber and the practicability of synthetic fiber. It has better performance, higher dye uptake rate, bright and full color, and strong elongation of sy...
