Embodiment 1

[0012] Mixed nylon and cotton samples (50:50 mass ratio input, cotton fabric specification: bleached cotton poplin, 40 s ×40 s , 132×72, 120g / m 2 ; Nylon 6 fabric specification: 70D / 24F, weight 130g / m 2 ) for dyeing. Take the following steps:

[0013] (1) Carry out pre-treatment such as desizing, scouring, and bleaching processes on nylon and cotton fabrics;

[0014] (2) pre-setting the pre-treated fabric, the setting process conditions are a temperature of 170°C and a time of 40 seconds;

[0015] (3) Add water according to the weight of the nylon cotton fabric to be dyed and the bath ratio of 15:1, put into the fabric and run for 5 minutes and then drop into the active dye M-2GE and 2ml of acetic acid with a good concentration of 1.8% (owf) after putting into the fabric. / l, disodium hydrogen phosphate 2g / l, anti-staining salt 3g / l, then heat up and run for 30 minutes, then add sodium carbonate 25g / l, urea 3g / l, sodium sulfate 20g / l, keep warm for 40 minutes, After cool...

Abstract

The invention discloses a polyamide cotton fabric one-bath dyeing method. After pretreatment and pre-setting treatment, the method comprises the following steps: adding water according to a bath ratio of 15:1 of polyamide cotton fabric to be dyed, charging the fabric and running for 5 minutes, orderly charging a molten reactive dye M-2GE with a concentration of 1.8%(owf), 2 ml/l of acetic acid, 2 g/l of disodium hydrogen phosphate, and 3 g/l of resist salt, heating, performing heat preservation and running for 30 minutes, adding 25 g/l of sodium carbonate, 3 g/l of urea, and 20 g/l of sodium sulfate, performing heat preservation and running for 40 minutes, cooling to 60 DEG C, draining, flushing, adding water to obtain a bath ratio of 1:15, adding 3 g/l of soaping agents, heating to 90 DEG C, washing with water for 15 minutes, cooling, draining, washing with water, drying, performing fixation treatment by a environment-friendly neutral dyeing fixing agent FRC, and finally performing setting and tentering.

Description

technical field [0001] The invention relates to the field of printing and dyeing, in particular to the same-bath dyeing method of nylon and cotton fabrics. Background technique [0002] Nylon-cotton fabric not only has the good moisture absorption and air permeability of cotton fiber, but also has the advantages of good elasticity and high wear resistance of nylon. It is widely used in various clothing fabrics and is deeply loved by consumers. However, since nylon and cotton fibers have different structures and different dyeing properties, dyeing often brings problems such as color registration difficulties and long process flow to enterprises. In terms of printing technology, the best dyes for nylon are acid dyes, but under acidic conditions, reactive dyes basically do not color cotton fibers, reactive dyes must be fixed under alkaline conditions, alkaline conditions will produce nylon printing Tremendous influence. Under alkaline conditions, the dyeing rate of nylon is v...
