preparation example Construction

[0036] The preparation method of polymer is as follows (each raw material is in parts by mass):

[0037] a. Put acrylamide, partial sodium persulfate and deionized water into the reactor, stir, dissolve, and heat up to 75°C;

[0038] b. Aqueous sodium persulfate solution, acrylic acid, and butyl acrylate are dropped into the reactor at a constant speed;

[0039] c. Lower the temperature of the reactor to 30°C, add sodium hydroxide first, and after it dissolves, add carbon disulfide, react, and filter to obtain a high molecular weight polymer.

[0040] The secondary amino group of acrylamide undergoes a nucleophilic substitution reaction with carbon disulfide to generate -CS 2 - group, which has a strong chelating performance on metal ions, and the metal ion chelate is stable and easy to settle; the carboxyl group, -CS in the molecular chain 2 - The synergistic effect of the groups enhances the chelating effect. Carboxyl group of acrylic acid, -CS 2 - The hydrophilic par...

Abstract

The invention relates to a scouring agent for cotton. The scouring agent is prepared from 9-16 parts of high-molecular polymer, 8-18 parts of AEO-9, 8-14 parts of Sodium secondary alkyl sulfonate, 6-10 parts of ricinoleic acid butyl ester sodium sulfate, 12-19 parts of FMES, 3-6 parts of ethylene glycol monobutyl ether, 7-15 parts of isomeric alcohol ethoxylate and 350-420 parts of deionized water. During preparation, the deionized water is added into a stirrer, then AEO-9 and isomeric alcohol ethoxylate are added, the temperature is increased to 50 DEG C, and stirring and dissolving are conducted; then SAS60, ricinoleic acid butyl ester sodium sulfate, FMES, ethylene glycol monobutyl ether and high-molecular polymer are added and evenly stirred, and the scouring agent can be obtained. The scouring agent for cotton has good alkali resistance, permeability, cleaning performance, emulsification performance, dispersity, oil removing performance and the like, does not contain APEO, and is environmentally friendly.

Description

technical field [0001] The invention relates to a scouring agent for cotton, which belongs to the field of printing and dyeing auxiliaries. Background technique [0002] The scouring of cotton fabrics is mainly to remove pectin, nitrogenous substances, grease, cotton wax, cotton seed hulls and other cellulose symbiosis, so that the fibers have good water absorption and a certain whiteness, so as to improve the dyeing and finishing performance of textiles. Auxiliaries for scouring used plant ash containing potassium carbonate (sodium) in the early days, and later changed to lime and sodium carbonate (soda ash). Now sodium hydroxide (caustic soda) is commonly used, plus detergent, sodium silicate (water glass) ), sodium bisulfite and water softener and other additives. Under the action of hot alkali solution for a long time, the oil and free fatty acid on the fiber will be saponified into soluble fatty acid salt, which will emulsify the wax and wash it off with water. Sodium...
