Problems solved by technology

The shrinking agents such as cleaning agent 105 and cleaning agent Jv, which belong to the non-ionic surfactant type, have the advantages of less damage to the wool fiber and less fading of the tweed, but the fabric after shrinking appears dull and has low biodegradability. Poor, serious environmental pollution

Embodiment 1

[0020] 1) Preparation of hydroxymethylacrylic acid, maleic anhydride and acrylamide copolymer: a. Add maleic anhydride (1.0mol) and water to a 1000ml four-necked flask equipped with a thermometer, reflux condenser, and double dropping funnel (500ml), heat up to 50~80°C, stir to dissolve, add 20~30% sodium hydroxide solution to adjust the pH to 5.5~7.0, and obtain liquid a; b. Weigh hydroxyacrylic acid (2.3mol), sodium persulfate ( 0.05mol), dissolved in 100ml water to obtain liquid b; c, weigh acrylamide (0.5mol); d, double drop b and c into liquid a at the same time, control the dropping temperature at 80~110°C, drop The time is 3~6 hours, the drop is completed, and the reaction is carried out under reflux for 10~16 hours. After the reaction is completed, the temperature is lowered to 50°C, and a yellow viscous polymer product is obtained.

[0021] 2) Compounding of woolen shrinkage cleaning agent: Add 9g of fatty alcohol polyoxyethylene ether-15, 10g of fatty alcohol polyoxy...

Abstract

The invention discloses a preparation method of a novel wool fabric milling detergent. The optimized detergent product with solid content being 20% is prepared by synthesizing a hydroxymethyl acrylate, maleic anhydride and acrylamide copolymer and compounding the copolymer with a wool fabric milling detergent. The obtained wool fabric milling detergent has excellent biodegradability, excellent detergent property and strong anti-staining capability and is safe and nontoxic, the wool fabrics washed with the detergent have smooth and plump feel, and the detergent can be used for washing wool fabric milling and soaping such fabrics as cottons, linens and silk.

Description

Technical field: [0001] The invention relates to a novel cleaning agent for woolen shrinkage, in particular to a preparation method of the novel cleaning agent for woolen shrinkage. Background technique: [0002] Wool fabric is deeply loved by consumers for its noble style and superior wearing performance. The consumption of woolen materials is increasing year by year, and the varieties of cotton and linen fabrics continue to diversify. However, unfinished woolen fabrics will experience felting (felting) when they are continuously squeezed and rubbed during washing. As a result, the size of the fabric shrinks, the surface becomes hairy, and the weave becomes chaotic. As a result, the woolen fabric can only be hand-washed or dry-cleaned at low temperature during use, and cannot be washed vigorously by washing machine, which causes a lot of trouble for the washing and care of the fabric. At present, as the shrinking agent in the wool spinning industry, the traditional varieti...
