Problems solved by technology

The method proposed in the patent has a certain effect on the anti-staining effect on the white background, but it has no anti-staining effect on the light-colored parts that have already been printed, which may cause color cross-over during the washing process

Abstract

The invention belongs to the technical field of textile printing, and in particular relates to a cation modified printing washing and anti-staining process of cellulose fiber fabrics. The process comprises a cation modification process, a reactive dye printing process and a washing process after printing, wherein the cation modification process comprises the steps of padding a modifier, stacking at the room temperature and washing; and the washing process after printing comprises the steps of preparing a washing liquid, washing for the first time-washing with the washing liquid in warm water,washing for the second time-washing with the washing liquid in warm water, washing for the third time-washing with the washing liquid in warm water, and washing in cold water. The process provided bythe invention can effectively prevent the dye back staining and staining and cross-coloring of the cation modified fabrics during the process of washing, which greatly improves the dye utilization rate, and expands the application range of the cation modified process of cellulose fiber fabrics.

Description

technical field [0001] The invention belongs to the technical field of textile printing, and in particular relates to a water-washing anti-staining process for cationic modified printing of cellulose fiber fabrics. Background technique [0002] With the development of society, more and more attention has been paid to environmental protection, and the field of textile printing and dyeing has also begun to develop towards green production. In the fiber dyeing process, in order to reduce the use of salt substances in dyeing and reduce environmental pollution, cationic modification Sexual printing technology came into being. Cationic modified printing can introduce cationic groups into fibers, reduce the charge repulsion between fibers and dyes, effectively reduce the addition of inorganic salts in the dyeing process, increase the utilization rate of dyes, reduce sewage discharge, save costs and protect the environment. [0003] However, a fatal problem in cationic printing is ...
