Wash-resisting polyamide fabric dyeing process

Abstract

The present invention discloses a wash-resisting polyamide fabric dyeing process comprising the following steps: a) base material dosing; b) cold heaping; c) heating; d) fiber treatment, to be more specific, 30 to 36 parts of a desizing refining agent, 13 to 18 parts of a fiber bulking agent, 15 to 20 parts of a dye leveling agent, 5 to 7 parts of a penetrating agent and 23 to 26 parts of glacial acetic acid are added into a dye vat, the PH value is adjusted, the PH value is maintained at 5.3 to 5.5, and the time is 2-5 hours; e) pretreatment; f) staining, to be more specific, baking soda is added, the PH value is adjusted to 9.5, dye tianlong yellow, tianlong blue and tianlong turquoise blue are added, water and the dyes are mixed into a dye liquid, and the weight ratio of dye tianlong yellow and cloth is 0.05: 1, the weight ratio of dye tianlong blue and cloth is 0.05: 1, and the weight ratio of dye tianlong turquoise blue and cloth is 0.5: 1; and g) color fixing, to be more specific, 5 to 9 parts of a color fixing agent and 3 to 7 parts of glacial acetic acid are added. Through the process, dyes are high in tendency in entering into the fabric, dye adhesion is large, the dyes are low in tendency to fall off by lighting and water washing, and damage to the internal structure of the fabric is small.

Description

【Technical field】 [0001] The invention relates to the technical field of nylon fabric dyeing, in particular to the technical field of a washing-resistant nylon fabric dyeing process. 【Background technique】 [0002] At present, the demand for nylon fabrics with bright colors is constantly increasing in the market. In the process of dyeing fabrics, acid dyes of corresponding colors need to be used for whatever color needs to be dyed. When acid dyes are used, there are many problems of uneven dyeing, resulting in low quality of finished fabrics and affecting market sales. When dyeing nylon fabric, due to the poor permeability of this fabric, the usual dyeing auxiliaries process will cause the dyeing effect of the fabric to be unsatisfactory, and the dye cannot enter the interior of the fabric. Not only the color of the dyed fabric and the sample color have a large error, However, color correction will produce additional disadvantages, and the adhesion of the dye to the fabric ...

When acid dyes are used, there are many problems of uneven dyeing, resulting in poor quality of finished fabrics and affecting market sales

When dyeing nylon fabric, due to the poor permeability of this fabric, the usual dyeing auxiliaries process will cause the dyeing effect of the fabric to be unsatisfactory, and the dye cannot enter the interior of the fabric. Not only the color of the dyed fabric and the sample color have a large error, However, color correction will produce additional disadvantages, and the adhesion of the dye to the fabric is poor. Such fabrics will be easily decolorized under sunlight and washing in the future.
