Problems solved by technology

Some printing and dyeing enterprises adopt one-step cold-stacking process, that is, rolling and stacking the material after rolling. Generally, it needs to be stacked for 30-40 hours at a temperature of about 30°C, and then washed and dried to complete the pre-treatment process. This process has low whiteness and poor hair effect, and is only suitable for...

Abstract

The invention relates to a textile continuous cold-batch auxiliary, a preparation method of the auxiliary and a method of textile pretreatment. The continuous cold-batch auxiliary is composed of two parts including LYM-A and LYM-B, wherein the LYM-A and the LYM-B are produced and stored in an independent auxiliary mode, when application of mass production is conducted, the two parts, hydrogen peroxide and sodium hydroxide are configured to form working solution according to different proportions and prescription requirements, continuous desizing, scouring and bleaching pretreatment is conducted on woven fabrics such as cotton and polyester cotton on a long vehicle device under the conditions of temperature of 35-45 DEG C and time of 50-90 minutes, the two parts of the auxiliary are both environment-friendly and do not contain banned chemicals. The method can replace a conventional high-temperature steaming pretreatment process.

Description

technical field [0001] The invention relates to a method for pretreatment of textile continuous cold stacking, auxiliary agents used and a preparation method thereof, belonging to the field of textiles. Background technique [0002] At present, the pretreatment process of woven fabrics in printing and dyeing enterprises is basically a two-step or one-step high-temperature steaming process. The two-step method is divided into two types. Boiling is steaming at 100-105°C for 40-60 minutes, washing with water and then bleaching. The bleaching process is steaming at 100-105°C for 50-70 minutes, then washing and drying. The second is the method of cold stacking and re-bleaching. First, pad the cold stacking working solution and roll it up for 20-30 hours at 25-45°C. Steam under low conditions for 40-60 minutes, then wash and dry. The one-step method is deboiling and bleaching for one bath, steaming at 100-105°C for 60-120 minutes after padding the working solution, and then wash...
