Abstract

The invention discloses a denim accelerating agent. The reactive dye accelerating agent is prepared from, by weight, 10-30 parts of sodium hydroxide, 10-20 parts of polyacrylamide, 20-30 parts of poly-oxalic acid fatty acid esters, 5-10 parts of sodium metasilicate, 5-15 parts of mica powder, 25-40 parts of sodium dodecyl benzene sulfonate, 40-55 parts of plant extracts and 10-30 parts of surfactants. According to the accelerating agent, level dyeing of the reactive dyes is promoted, the technology is greatly simplified, the time is shortened, and the cost and wastewater treatment load are reduced; the accelerating agent is mainly obtained from the plant extracts and is free of poison and environmentally friendly, damage to a worker body cannot be caused, harm to denim is less, and no harm to a human body can be caused when the denim serves as clothes; the accelerating agent is easy and convenient to prepare and suitable for large-scale industrialized popularization.

Description

technical field [0001] The invention relates to a dyeing accelerator, in particular to a denim dyeing accelerator and a preparation method thereof. Background technique [0002] In daily life, denim is sought after by everyone because of its natural color, comfortable wearing, wear-resistant, good matching and many other advantages, but denim fading is the most common phenomenon. Due to the darker color of denim and poor dyeing fastness, the dye is easy to fall off and fade when it encounters washing, sunlight or physical friction, which not only affects the appearance, but also makes the clothes look worn; Separate cleaning will greatly increase the workload, waste resources and waste time. [0003] At present, due to the uneven dispersion of dyes and the hydrolysis of dyes in the dyeing of denim, the dyed denim has problems such as poor fastness, easy fading and decreased strength. There are problems such as complex processing technology and long time. Adding dye accele...
