Problems solved by technology

[0002] The existing nylon fabric dyeing technology is prone to uneven coloring, color wrinkles and other defects, which cannot meet consumers' requirements for high-quality fabrics, thus limiting the popularization and application of nylon fabrics
The traditional fabric finishing and dyeing process includes desizing, scouring, chlorine bleaching, pre-setting, dyeing, drying, and setting processes. First, there is no impurity removal treatment before the desizing process. The surface of the fabric is relatively rough, which will affect Finishing and dyeing effect; secondly, when the fabric is dyed with dark dyes, it is easy to cause poor color fastness of the dyed fabric, fading, wrinkles and other phenomena, which will affect the finishing and dyeing effect of the fabric

Embodiment Construction

[0019] A kind of dark color dyeing process of nylon fabric, comprises the following steps:

[0020] (1) Singeing: Singeing the nylon fabric and removing the burrs of the nylon fabric;

[0021] (2) Washing: Use 8-9g / L neutral detergent to wash the nylon fabric, the bath ratio is 1:12, the washing temperature is 55°C, and the washing time is 30 minutes;

[0022] (3) Pretreatment: Add water softener and penetrating agent with a mass ratio of 1% and detergent with a mass ratio of 1.2%-2.8% at a bath ratio of 1:25-1:34 and 60-75°C 1. Treat the washed nylon fabric for 10-30 minutes, and pre-set the pretreated nylon fabric at 160°C for 5 minutes;

[0023] (4) Scouring: Scouring the pre-shaped nylon fabric at a temperature of 120-160°C;

[0024] (5) Oxygen bleaching: use hydrogen peroxide to bleach and decontaminate the boiled nylon fabric;

[0025] (6) Dyeing: Put the nylon fabric in water at 30°C, add 6g / L soda ash and 3g / L degreaser, let it stand for 25 minutes, add dark dye, ad...

Abstract

The invention discloses a nylon fabric deep color dyeing method. The nylon fabric deep color dyeing method comprises: (1) singeing, (2) water washing, (3) pretreatment, (4) scouring, (5) oxygen bleaching, (6) dyeing, (7) fixing, (8) cleaning and (9) drying. Compared with the prior art, the dyeing method utilizes singeing and water washing processes before pretreatment to remove impurities on the surface of the fabric and utilizes a tentering process after dyeing to prevent wrinkling of the set fabric and improve dyeing and finishing effects. The method using a deep color dye realizes uniform color absorption of a finished product and good color fastness. The dyed nylon fabric is soft and fluffy.

Description

technical field [0001] The invention relates to the field of fabric dyeing and finishing, in particular to a dark dyeing process for nylon fabrics. Background technique [0002] The existing nylon fabric dyeing technology is prone to uneven coloring, has defects such as color wrinkles, and cannot meet consumers' requirements for high-quality fabrics, thereby limiting the popularization and application of nylon fabrics. The traditional fabric finishing and dyeing process includes desizing, scouring, chlorine bleaching, pre-setting, dyeing, drying, and setting processes. First, there is no impurity removal treatment before the desizing process. The surface of the fabric is relatively rough, which will affect Finishing effect; secondly, when the fabric is dyed with dark dyes, it is easy to cause poor color fastness of the dyed fabric, fading, wrinkles and other phenomena, which will affect the finishing effect of the fabric. Contents of the invention [0003] The purpose...
