Problems solved by technology

This process has the following disadvantages: (1) the reaction must be carried out at high temperature, and the bleaching effect of hydrogen peroxide must be above 95°C to be effectively exerted
(2) A large amount of steam is consumed. 1 ton of cotton knitwear requires about 5-6 tons of steam, accounting for about 60% of the entire steam consumption for dyeing and finishing.
(3) Strong damage, high fabric weight loss rate
(4) Severe fiber shrinkage, easy to wrinkle
But, have used alkaline pectinase in this scouring agent, make the stability of scouring agent not very good, the selected surfactant butyl ricinoleate sodium sulfate, alkanolamide polyoxyethylene ether, coco The scouring effect of oleamidopropyl betaine is poor at low temperature, and the foam is very large, which affects the running of the fabric, and the cost is high
[0005] At present, the existing low-temperature scouring agent has the problem that hydrogen peroxide cannot effectively release active oxygen at low temperature (60-80°C), and cotton wax cannot be effectively removed, resulting in low wicking height of the fabric, unsatisfactory scouring effect, difficult biodegradation, resulting in rich water. nutrition problem

Abstract

The invention relates to the technical field of printing and dyeing auxiliaries, in particular to a low-temperature scouring agent and a preparation method thereof. The low-temperature scouring agentis prepared from the following components in percentage by weight: 0.2 to 0.8 percent of a hydrogen peroxide activating agent, 21.8 to 39.2 percent of a low-foaming surfactant, 3 to 10 percent of a scouring assistant and 50 to 75 percent of deionized water. By adopting the low-temperature scouring agent provided by the invention, hydrogen peroxide can be decomposed effectively at low temperature,a high-temperature scouring effect can be achieved by releasing active oxygen, cotton wax can be removed effectively at a low temperature, and a good, uniform and consistent scouring effect and high efficiency are achieved during low-temperature scouring. Moreover, the low-temperature scouring agent provided by the invention is environmentally friendly, and is biodegradable.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing auxiliaries, in particular to a low-temperature scouring agent and a preparation method thereof. Background technique [0002] Cotton knitted fabrics need to be pre-treated before dyeing, using caustic soda as a hydrolyzing agent and saponifying agent for protein, pectin, and oil wax, and then using a surfactant to emulsify and disperse the decomposed products to remove them from the cotton fiber. Oxidation of hydrogen peroxide Acts to bleach fabrics. The traditional pre-treatment of cotton knitted fabrics adopts the intermittent 95-100°C scouring process in overflow dyeing vats. This technique has the following disadvantages: (1) the reaction must be carried out at high temperature, and the bleaching effect of hydrogen peroxide must be effectively brought into play above 95° C. simultaneously. The traditional cotton knitting process is carried out at 95-100°C, and the scouring and b...
