Abstract

The invention discloses an environment-friendly pre-treatment liquid for a printing and dyeing process. The liquid is prepared from the following components in parts by mass: 20-30 parts of fatty alcohol-polyoxyethylene ether, 20-25 parts of sodium alkyl alcohol ether carboxylate, 10-15 parts of lauryl azone, 3-6 parts of ethyl salicylate, 4-10 parts of isopropyl salicylate, 10-15 parts of secondary alkyl sulphonate, 1-2 parts of hydrogen peroxide, 1-5 parts of ethylene oxide, 1-5 parts of sodium chloride and 50-60 parts of deionized water. The liquid disclosed by the invention is reasonable in formula and simple in preparation method and can be used for treating a gray fabric during printing and dyeing, so that the subsequent dyeing effect is good.

Description

technical field [0001] The invention relates to the field of printing and dyeing, in particular to a pretreatment liquid for the printing and dyeing process. Background technique [0002] Fabrics that have not been dyed and finished are collectively referred to as raw fabrics or gray fabrics. The purpose of the pre-printing and dyeing treatment is to remove all kinds of impurities on the fabric with little damage to the gray fabric, so that the gray fabric becomes a white, soft and printing and dyeing semi-finished product with good wetting properties. Pretreatment of printing and dyeing is the preparatory process of printing and dyeing processing, also known as scouring and bleaching. For the pretreatment of cotton and cotton-type fabrics, there are processes such as preparation, singeing, desizing, scouring, bleaching, and mercerizing. Some existing pretreatment liquids of printing and dyeing processes, due to the low coupling rate of dye groups and fibers, low adsorption...
