Abstract

The present invention relates to a soybean protein fiber dyeing adjuvant. It is characterized by that it contains 0.50-0.8% (on weight of fabric) of alkyl-polyoxyethylene non-ionic surfactant, 10-30g / l of anhydrous sodium sulfate, it uses formic acid to regulate pH value of dye bath to 4.5-5.5, then uses caustic soda to regulate pH value of dye bath to 11. Besides, in said adjuvant 0.25-0.505 (onweight of fabric) of aluminium salt is also contained; the described aluminium salt is any one of aluminium sulfate, aluminium trichloride and alum or their mixture. Said invention also provides the concrete steps of said dyeing process by using said dyeing adjuvant and soybean protein fiber.

Description

technical field [0001] The invention relates to a soybean protein fiber dyeing auxiliary and a dyeing process thereof, belonging to the field of textile dyeing and finishing. Background technique [0002] Reactive dyes are generally used for dyeing soybean protein fibers, while the dyeing percentage and fixation percentage of dyes to fibers are generally low when traditional dyeing auxiliaries and dyeing processes are used. In order to solve this problem, a large amount of inorganic salts such as Yuanming powder will be added in the dyeing process to promote dyeing. However, the biggest disadvantage of adding a large amount of inorganic salts to promote dyeing is that it will make the textiles feel rough, and may cause scratches on the dyed textiles, making it difficult for the quality of the dyed textiles to reach a higher target, which seriously affects the product grade and sales of the dyed textiles. price. For a long time, the dyeing and finishing industry has not bee...
