Problems solved by technology

[0003] However, the inventor has found in long-term production practice that the one-bath production method also has defects such as insufficient desizing while realizing the three-step combination of desizing, scouring and bleaching, resulting in reduced tear strength of the fabric. Defects such as difficulty in dyeing and printing in the post-processing section are manifested in poor printing penetration, resulting in blooming on the surface of the fabric, difficulty in aligning the fabric, and a decline in the dyeing quality of sensitive colors and medium-dark colors, etc., which urgently need further improvement

Abstract

The present invention discloses one kind of pre-treating agent for fabric printing and dyeing and its application. The pre-treating agent includes pre-treating water solution in 40-60 wt% and promoter in 40-60 wt%. The pre-treating agent may be used in the pre-treatment of cotton fabric and blended fabric before printing and dyeing. The cotton fabric and blended fabric treated with the pre-treating agent has full desizing, no degradation in strength and easy printing and dyeing.

Description

technical field [0001] The invention relates to a printing and dyeing pretreatment agent for cotton and its blended fabrics and its application, in particular to a one-bath pretreatment method for cotton and its blended fabrics. Background technique [0002] As we all know, the scouring and bleaching process of textile printing and dyeing includes three processes of desizing, scouring and bleaching, which are completed in three independent processes. Fiber damage is also more obvious. For this reason, Chinese Patent Application No.: 03150594.5 discloses a production method that adopts a one-bath production process to realize three-step desizing, scouring and bleaching, adopts biological enzymes and chelating dispersants to form an efficient green pretreatment agent, and adds Hydrogen peroxide is used to prepare the treatment solution, and the fabric is subjected to padding heat stacking treatment on a continuous steaming long car, washed with water, dried, or dip-dyeed on a...
