Abstract
The invention relates to a low-temperature scouring and bleaching aid for textiles as well as a preparation method and application of the low-temperature scouring and bleaching aid. The low-temperature scouring and bleaching aid comprises the following components of a metal complex and a scouring and bleaching agent, wherein the addition amount of the metal complex accounts for 0.01-99.9 percent of the total weight. The preparation method comprises the following steps of: adding the metal complex into the scouring and bleaching aid according to the proportion that the metal complex accounts for 0.01-99.9 percent of the total weight of reactant, and stirring for 15-30min to obtain the low-temperature scouring and bleaching aid. According to the invention, the metal complex is added into the conventional scouring and bleaching aid for textiles, so that the efficiency of the aid can be increased; when the low-temperature scouring and bleaching aid is used for a pretreatment process in which hydrogen peroxide is used as a bleaching agent, the scouring and bleaching temperature can be reduced, and the scouring and bleaching temperature of the textiles can be reduced to 60-85 DEG C from 95-100 DEG C or even below, therefore the production energy consumption is greatly reduced. The low-temperature scouring and bleaching aid has favorable application prospect.
