Problems solved by technology

[0004] However, cationic dyes also stain nylon, so when acid dyes and cationic dyes are used to dye nylon and acrylic flocked flocked fabric in one bath, cationic dyes will not only stain acrylic, but also stain nylon. color, so one-bath dyeing of nylon and acrylic mixed flocked flocked fabric with acid dyes and cationic dyes has not been achieved

Abstract

The invention belongs to the technical field of dyeing technology, and in particular relates to a one-bath dyeing process for flocked fabric by hybrid flocking of nylon and acrylon, which comprises the following steps of: performing treatment before dyeing; controlling the bath ratio of 1:5-15; adding a defoaming agent, an acid dye leveling agent, a cationic ion leveling agent, an acid dye and a cationic dye in turn, and respectively maintaining for 3 to 5 minutes; raising the temperature to 60 DEG C at a rate of 1-2 DEG C / min, and adding dyeing acid and anhydrous sodium sulphate, raising thetemperature to 98 DEG C at a rate of 1-2 DEG C / min, and keeping the temperature for 30 to 60 minutes; reducing the temperature to 70 DEG C and performing plate shear and color contrast; adding a color fixing agent and keeping the temperature of 70 DEG C for 20 minutes; and discharging water, washing with water, and taking out of a vat. The process solves the problem of staining the nylon by the cationic dye; the flocked fabric by the hybrid flocking of nylon and acrylon is subjected to the one-bath dyeing by using the acid dye and the cationic dye; the dyeing cost is reduced; the process timeis shortened; and the flocked fabric with unique style and rich colors by the hybrid flocking of nylon and acrylon can be made.

Description

technical field [0001] The invention belongs to the technical field of dyeing process, and in particular relates to a one-bath dyeing process of flocked cloth flocked with nylon and acrylic fiber mixed. Background technique [0002] In the prior art, when making flocked cloth with both nylon and acrylic components, nylon and acrylic are dyed separately first, and then processed, which not only increases the dyeing cost but also prolongs the process time. [0003] Nylon is mainly dyed with acid dyes and neutral dyes, and acrylic is mainly dyed with cationic dyes. Among them, the dyeing process conditions of acid dyes and cationic dyes are relatively similar, which provides the possibility of one-bath dyeing of flocked fabrics mixed with nylon and acrylic fibers. The one-bath dyeing of flocking cloth can not only reduce the dyeing cost and shorten the process time, but also make flocking cloth with unique style and ever-changing colors of nylon and acrylic fiber mixed flockin...
