CN104420351A - Dyeing process of silk knitted fabric active dye - Google Patents

Abstract

The invention discloses a dyeing process of a silk knitted fabric active dye. The dyeing process of the silk knitted fabric active dye comprises the steps of dyeing, fixing color, rosining, soaping, washing in hot water, washing in cold water and drying. Silk knitted fabrics are dyed by active dyes so that color is bright and dye fastness is good; the process is simple and convenient; silk abrasion caused by high-temperature dyeing on the silk knitted fabrics can be avoided.

Description

Real silk knit goods reactive dyeing process

 

Technical field

The invention belongs to dyeing engineering for knitted fabric, be specifically related to a kind of real silk knit goods reactive dyeing process.

 

Background technology

For a long time, real silk knit goods continues to use ACID DYES or neutral dyeing always.ACID DYES dyeing silk knitted fabric is bright in colour, but wet fastness is poor, and neutral dye dyeing silk knitted fabric wet colour fastness is better, but color and luster is bright-coloured not.

 

Summary of the invention

In order to overcome the above-mentioned defect that prior art field exists, the object of the invention is to, provide a kind of real silk knit goods reactive dyeing process, bright in colour, COLOR FASTNESS is good.

Real silk knit goods reactive dyeing process provided by the invention, processing step is as follows:

A () is dyeed: real silk knit goods is put into the dye liquor containing X-type REACTIVE DYES 8-10 g/L, bath raio 1:30, rise to 40 DEG C from room temperature, after 40 DEG C of dyeing 10min, add the glauber salt of people's half amount, contaminate and add second half glauber salt measured again to 30min, continue dye 20min;

(b) fixation: add soda ash fixation 30min;

C () washes: clean real silk knit goods with clear water;

D () soaps: soap to real silk knit goods in containing the solution of detergent LS2%-3%, bath raio 1:20, and temperature of soaping is 90 DEG C, time 10min;

(e) hot water wash: real silk knit goods is cleaned with the water of 90 DEG C;

(f) cold wash: real silk knit goods is cleaned with clear water;

G () dries.

Real silk knit goods reactive dyeing process provided by the invention, its beneficial effect is, adopts REACTIVE DYES to dye to real silk knit goods, not only bright in colour, and dyefastness is good, simple process, and real silk knit goods can be avoided to hinder because high-temp dyeing produces ash.

 

Detailed description of the invention

Below in conjunction with an embodiment, real silk knit goods reactive dyeing process provided by the invention is described in detail.
