Problems solved by technology

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

Abstract

The invention relates to the field of dyeing assistants, in particular to a reactive dyeing assistant for polyester fibers. The reactive dyeing assistant comprises a surfactant, sodium sulfate, a water softener, branched heterogeneous alcohol ether, rare earth chloride, 3-chloro-2-hydroxypropyltrimethyl ammonium chloride and goose feather protein extracted from goose feather. According to the reactive dyeing assistant for the polyester fibers, the degree of dyeing and the degree of fixation of the polyester fibers can be increased effectively by the aid of addition of a small amount of sodium sulfate and cooperation of the goose feather protein, only a small amount of sodium sulfate is added, so that scratching of polyester fiber textiles can be avoided, the quality of polyester fibers in a dyeing process is guaranteed, and the usability is improved; meanwhile, the utilization rate and the dyeing efficiency of a dye can be increased effectively by the aid of the assistant, water used in the dyeing process of unit textile can be reduced, the production cost is reduced, and environmental safety is guaranteed.

Description

technical field [0001] The invention relates to the field of dyeing auxiliaries, in particular to a reactive dyeing auxiliaries for polyester fibers. Background technique [0002] Reactive dyes are generally used for dyeing polyester 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 should be added to promote dyeing during the dyeing process. 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 been unable to solve this technical problem, making poly...
