Problems solved by technology

Although the polymer soaping agent solution prepared by this method has strong stability and good soaping effect, the process of the method is complicated, and the prepared soaping agent does not have oxidative decomposition effect on the floating color washed.
[0005] So far, no matter whether it is the introduction of the third monomer, polymerization or compounding with other components, it is realized on the horse-acrylic copolymer liquid, so that a higher content of soaping agent or soaping powder cannot be prepared, and there are few Considering the chromaticity of the residual liquid after soaping, energy saving and emission reduction are not well combined
In addition, there is currently no soaping powder that has an excellent soaping function at low temperatures and has a decolorization function for soaping residues, and it is difficult to effectively achieve the unity of energy saving and emission reduction.

Abstract

The invention relates to low temperature soaping powder and a preparation method thereof. So far, there has been no soaping powder which has excellent soaping performance at low temperature and decolouring performance to soaping residue. The low temperature soaping powder provided in the invention comprises, by weight, 25 to 65 parts of maleic anhydride-acrylic acid copolymer powder, 35 to 85 parts of sodium percarbonate and 35 to 85 parts of sodium perborate. The preparation method for the low temperature soaping powder comprises the following steps: with an aqueous solution of maleic anhydride-acrylic acid copolymer, sodium percarbonate and sodium perborate as raw materials, heating the aqueous solution of maleic anhydride-acrylic acid copolymer to a temperature of 70 to 90 DEG C under agitation, subjecting the aqueous solution of maleic anhydride-acrylic acid copolymer to vacuum distillation for 2 to 5 hours at a temperature of 70 to 90 DEG C and cooling the aqueous solution of maleic anhydride-acrylic acid copolymer to a temperature of 60 to 70 DEG C; subjecting the aqueous solution of maleic anhydride-acrylic acid copolymer to vacuum drying for 8 to 15 hours at a temperature of 100 to 150 DEG C, crushing dried maleic anhydride-acrylic acid copolymer and mixing crushed maleic anhydride-acrylic acid copolymer with sodium percarbonate and sodium perborate to prepare the soaping powder. The low temperature soaping powder provided in the invention has strong soaping performance, strong anti-staining performance, and decolouring performance to soaping residue.

Description

technical field [0001] The invention relates to a soaping powder and a preparation method thereof, in particular to a low-temperature soaping powder and a preparation method thereof. The low-temperature soaping powder can perform low-temperature soaping and decolorization on dyed cotton, linen and their blended fabrics. Background technique [0002] Reactive dyes have become the most used dyes in the dyeing of cellulose fibers, but the low utilization rate of dyes due to the hydrolysis of dyes during the dyeing process is still one of its disadvantages, and the hydrolysis of dyes also brings a serious problem , That is, the hydrolyzed dye will be adsorbed on the fiber, which constitutes the main component of the floating color of the dyed matter. After the fabric is dyed, it must be washed to remove the hydrolyzed dye and a small amount of unreacted dye on the fiber, otherwise it will seriously affect the fastness of fabric dyeing. Soaping powder is generally used for washin...
