CN104233876A - Dyeing method for nylon fabric - Google Patents

Abstract

The invention discloses a dyeing method for nylon fabric. The dyeing method comprises the following steps: (1) pretreatment, wherein newly-produced nylon fabric to be dyed is bagged and put into a washing machine for washing for 10-20min, 4-6g/L neutral detergent is added, and the bath ratio is 1:20 to 1:30; (2) presetting, wherein presetting treatment is carried out on the washed nylon fabric at the temperature of 120-140 DEG C; (3) low-temperature dyeing, wherein a dyeing system comprises the following components in percentage by weight: 0.5%-2.5% of a dyeing additive, 0.12%-0.18% of a zwitterionic type leveling agent and 2%-5% of an acid color-fixing agent, and the bath ratio is 5-8; and (4) drying, namely after being dyed, a product is dried by a drying machine. The dyeing method disclosed by the patent adopts the dyeing process of pretreatment, presetting, low-temperature dyeing and drying, so that the nylon fabric is uniform in coloring, is unlikely to generate folds and can meet the requirement of people on high quality of the nylon fabric.

Description

A kind of colouring method of nylon fabrics

Technical field

The present invention relates to a kind of dyeing, particularly relate to a kind of colouring method of nylon fabrics.

Background technology

Nylon facing material is soft fluffy, satiny uniqueness, ABRASION RESISTANCE is good, become the first-selection of outdoor activity fabric, but existing nylon facing material staining technique easily occurs painted uneven, washing fastness is low, and dyeing temperature is all at 100 DEG C, fabric easily produces fold, affects the practical effect of nylon facing material, thus limits applying of nylon fabrics.

Summary of the invention

The invention provides a kind of colouring method that can overcome the nylon facing material of the problems such as traditional handicraft temperature is high, dyeing inequality, fabric out-of-flatness.

For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of colouring method of nylon fabrics, the steps include:

1) preliminary treatment: nylon fabrics to be dyed for new production pack is dropped into rinsing machine and washes, add the neutral detergent of 4-6g/L, bath raio is 1:20-1:30, and washing time is 10-20min;

2) pre-setting: the nylon fabrics after washing is carried out pre-setting process at 120-140 DEG C;

3) low temperature dyeing: dyeing system is by weight: dyeing assistant 0.5%-2.5%; Zwitterionic classes dye leveller 0.12%-0.18%; Acidic color fixing agent 2%-5%; Bath raio 5-8;

Dyeing curve: the heating rate of dyeing is set in 0.5 DEG C/min-1.0 DEG C/min, and the highest temperature is 80 DEG C-85 DEG C, and constant temperature time is 10min-30min, then with the speed cooling of 1 DEG C/min-2 DEG C/min;

4) dry: after dyeing product, through drying machine drying.
