Abstract

The present invention provides a rubbing fastness improving finishing process of a deep color cotton and a blended fabric thereof. According to the present invention, a fabric is subjected to a color fixation treatment with an aromatic sulfonic acid condensate, drying is performed, and finishing is performed with a slightly-turbid-state rubbing fastness improving working liquid containing a cationic aqueous polyurethane compound, such that the dry rubbing fastness and the wet rubbing fastness of the good hydrophilicity deep color cotton and the blended fabric thereof can achieve more than or equal to grade 3, and the difficult problem that the rubbing fastness is difficult improved through the conventional processing process is effectively solved.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing, in particular to a process for improving the rubbing fastness of dark-colored cotton and its blended fabrics. Background technique [0002] Cotton and its blended fabric dyed cloth and printed cloth have better rubbing fastness after being fixed by common color fixing agents when the color is lighter, which can meet the requirements of customers. However, the wet rubbing fastness of medium-dark cotton and its blended dyed and printed fabrics is poor, especially for some thinner fabrics or dark fabrics through conventional methods such as enhanced soaping and adding better smoothing agents. 1. Select the better active color fixing agent and water-based polyurethane polymer cationic compound on the market for color fixing treatment, but the rubbing fastness still cannot be improved. However, in recent years, with the continuous improvement of the quality threshold in economically develop...
