Problems solved by technology

The whole process steps are cumbersome, the production efficiency is low, and the energy consumption is high
In order to shorten the process, the same-bath deoxidation dyeing process has been studied and partially applied, but because the polishing process generally requires acidic conditions, and the dyeing of reactive dyes requires color fixation under alkaline conditions, so the two processes of polishing and dyeing are restricted. Due to the influence of different acid and alkali conditions, it is impossible to operate in the same bath, which limits the progress of the three-step process of deoxidation, polishing and dyeing in the same bath.

Abstract

The invention provides a towel treating process which belongs to the technical field of textile production processes. The process comprises steps of pretreatment scouring and bleaching, neutralizing, deoxidizing, dyeing, soap boiling, polishing, softening and the like. The process is characterized in that deoxidizing, dyeing and polishing steps in the conventional process are completed in one step. The process is simple. By adopting the process, the consumption of water, electricity and steam is greatly reduced and the production efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of textile production technology, and in particular relates to a towel treatment technology. Background technique [0002] At present, the treatment process of towels mainly adopts the following steps: pre-treatment scouring and bleaching→neutralization→deoxidation→dyeing→soaping→polishing→softening. Among them, towels need to add hydrogen peroxide in the pretreatment, scouring and bleaching. The residual hydrogen peroxide will affect the reaction between reactive dyes and cotton fibers during the dyeing process. Therefore, it is necessary to deoxidize before dyeing. Now the commonly used deoxidizer is catalase. . After the towel is dyed, in order to improve the appearance, reduce the hairiness and the stained hairball after washing, it needs to be polished. The polishing adopts the method of cellulase biological polishing. The polishing is generally carried out after the dyeing and soaping. The entire tre...
