CN102154847A - Dye liquor for silk fabric and dyeing process - Google Patents

Abstract

The invention discloses a dye liquor for a silk fabric and a dyeing process. The dye liquor comprises the following ingredients of 3 percent o.w.f (on weight the fabric) of reactive dye, 30 g/L of anhydrous sodium sulphate and 20 g/L of sodium carbonate; and the bath ratio is 1:20. The dyeing process comprises the following steps of: putting the dye liquor in a dye jar; adjusting the pH value of the dye liquor to 4-5; raising the temperature to 40 DEG C; putting the fabric in the dye liquor and preserving the temperature for 15 minutes; putting in the sodium carbonate and preserving the temperature for 10 minutes; raising the temperature to 60-70 DEG C in the rate of 3 DEG C/min, and preserving temperature for 15 minutes; adding sodium carbonate and preserving temperature for 30 minutes; and finally washing. The dyeing process is simplified, the production practice is shortened, and the production efficiency is increased. The aim of producing products with high union dyeing property can be well realized through the dyeing process.

Description

A kind of dye liquor of silk fabrics and dyeing

Technical field

The present invention relates to a kind of dye liquor and dyeing of silk fabrics.

Background technology

For making mulberry silk, cotton, numb three components in the dyeing process, obtain good homochromatism, adopt REACTIVE DYES that silk/numb cotton product is carried out one-bath dyeing.But silk, numb COTTON FABRIC adopt the homochromatism problem in the reactive dyeing to be difficult to solve.

Summary of the invention

The present invention seeks to provide a kind of dye liquor and dyeing of silk fabrics at the defective that prior art exists.

The present invention adopts following technical scheme for achieving the above object:

The dye liquor of a kind of silk fabrics of the present invention comprises following component:

REACTIVE DYES 3%(o.w.f);

Glauber salt 30g/L;

Soda ash 20g/L;

Bath raio 1:20.

A kind of dyeing of dye liquor of silk fabrics is as follows:

Dye liquor is placed in the dye vat, and regulating dye liquor ph value is 4-5; Be warming up to 40 degree; Put into fabric and be incubated 15min; Put into soda ash and be incubated 10min; The speed of 3 degree/min is warming up to the 60-70 degree, insulation 15min; Add sodium carbonate and be incubated 30min; Washing at last.

The present invention simplifies technology, shortens production practices, enhances productivity.This dyeing can well solve and will obtain the high product of homochromatism.

The specific embodiment

The dye liquor of a kind of silk fabrics of the present invention, it is as follows to fill a prescription:

REACTIVE DYES 3%(o.w.f);

Glauber salt 30g/L

Soda ash 20g/L;

Bath raio 1:20.

Technology:Prepare dye liquor by prescription, place in the dye vat, regulating dye liquor ph value be 4-5---be warming up to 40 degree---put into fabric---and be incubated 15min---put into soda ash---insulation 10min---speed of 3 degree/min is warming up to the 60-70 degree, is incubated 15min, and------being incubated 30min---washes to add sodium carbonate.

Claims (2)

1. the dye liquor of a silk fabrics is characterized in that comprising following component:
