Abstract

Relating to the field of silk production, the invention discloses a silk dyeing method, which includes the steps of: A. degumming the silk by an enzyme agent for 100-120min under a 40-50DEG C environment with a pH value of 7-9; B. starting dyeing in a neutral environment of 25-30DEG C, heating the dye, a chelating dispersing agent and a true silk leveling agent gradually to 98DEG C within 20-30min, performing heat preservation for 10-20min, lowering the temperature to less than 80DEG C, adding acetic acid slowly in two times, slowly raising the temperature to 98DEG C, and conducting heat preservation till the dye is basically exhausted; and C. subjecting the colored silk to soaping, cleaning, washing by cold water, softening agent application, dehydration, scutching, and drying in order. By adopting enzymatic degumming, the method provided by the invention is moderate, has the characteristics of low cost, little damage to silk fibroin, uniform coloring, no color difference, difficult fading, and no influence to the original performance of silk, and can effectively increase the service time of silk clothing.

Description

A kind of dyeing silk method

Technical field

The present invention relates to silk production field, be specifically related to a kind of dyeing silk method.

Background technology

Silk is popular clothing recent years, with because have natural gloss, pulling force and with crude steel line slightly etc., Toughness Ratio institute body is artificial and natural fabric is strong, not easily hook yarn damaged, the hygroscopicity that tool cotton fiber is 1.5 times, can absorb rapidly and distribute human body sweat gas, moisture absorption is moisture releasing again, and few electrostatic, anti-wholely growing germ, is best health fiber, so commercially reflection is very well general.The technological process control of current true dyeing silk is still domestic textile enterprise particularly a kind of production method of adopting of silk weaving enterprise.In process of production, how to control, reduce and overcome the uneven dyeing such as dyeing silk aberration, look flower, easily the problem such as to fade, with obtain desirable Color be produce at present in urgent problem.

Summary of the invention

The object of the invention is the defect for above-mentioned prior art, provide a kind of dyeing silk method, there is the advantage that Color is good, not easily fade.

Object of the present invention can be achieved through the following technical solutions:

A kind of dyeing silk method, comprises the following steps:

A, adopt enzyme agent to come unstuck silk, be 40 ~ 50 DEG C in temperature, pH value is the 100 ~ 120min that comes unstuck under the environment of 7 ~ 9;

B, the neutral environments of 25 ~ 30 DEG C start dyeing, dyestuff, chelated dispersants, real silk levelling agent are warming up to 98 DEG C gradually in 20 ~ 30min, and insulation 10 ~ 20min, is down to less than 80 DEG C and slowly adds acetic acid at twice, slowly be warming up to 98 DEG C, be incubated to dyestuff substantially complete;

C, the silk of having painted soaped successively, cleaned, cold water is cleaned, upper softener, dehydration, beat silk, airing.

Preferably, steps A carries out fully washing removal hydrolysate after terminating.

Preferably, after adding acetic acid in step B for twice, ph value is 4 ~ 6.

Beneficial effect of the present invention: the present invention adopts enzyme to come unstuck comparatively to relax, and cost is low, little to fibroin damage, evenly, no color differnece, not easily fades, and can not affect the original performance of silk in colouring, effectively increases the service time of silk clothing.

Detailed description of the invention

Below in conjunction with embodiment, the specific embodiment of the present invention is described in further detail:
