Embodiment 1

[0028] Example 1: Biological Enzyme Degumming Treatment of Plain Crepe Satin Fabric

[0029] Take 5 kg of crepe and satin white gray cloth, put it in the pretreatment pool, add water, the bath ratio is 1:50, evenly add 1 g / L of biological enzyme (protein biological enzyme), pH value is 5, heat up to 60 ° C, and treat for 3 hours , rinse with cold water, and curl.

Embodiment 2

[0030] Embodiment 2: chiffon fabric bio-enzyme degumming treatment

[0031] Take 5 kg of chiffon fabric white gray cloth, put it in the pretreatment tank, add water, bath ratio 1:40, evenly add biological enzyme (protein biological enzyme) 1g / L, pH value 5, heat up to 60°C, and treat for 2.5 hours , rinse with cold water, and curl.

Embodiment 3

[0032] Embodiment three: tea pigment dyeing 20m / m plain crepe satin process

[0033] The first step: crepe satin fabric bio-enzyme degumming treatment: same as Example 1

[0034] The second step: Subsequent mordant dyeing treatment:

[0035] Put the pretreated plain crepe satin in the dyeing vat, add water, the bath ratio is 1:50, add acetic acid (commonly known as acetic acid) to adjust the pH value to 4, start heating at 30°C, and keep the heating rate at 2°C / min. Treat at 60°C for 30 minutes. Add 40g of mordant: ferrous sulfate; theaflavin plant dyes: added evenly afterward, with an amount of 50g; the temperature starts to rise from 50°C, the heating rate is maintained at 1°C / min, and the treatment is carried out at 80°C for 30min. Washing in cold water: bath ratio 1:50, water temperature: 30°C, treatment for 10 minutes; soaping after draining (industrial soap: content 2%): bath ratio 1:50, water temperature 40°C, time 10 minutes; washing with hot water after draining: T...

Abstract

The present invention is technological process of dyeing silk fabric with vegetable dye and belongs to the field of fabric producing technology. The technological process includes the following steps: degumming silk fabric biologically with enzyme, flushing with cold water, and winding; dyeing the degummed silk fabric through adding acetic acid to regulate pH value, adding neutral phosphate and mordant, adding tea lutein as vegetable dye and heating; cold water washing, soaping, hot water washing, cold water washing, stoving, pre-shrinking to set breadth, and winding or packing. The dyeing process has high dyeing homogeneity, high stability and less damage to silk fabric.

Description

technical field [0001] The invention relates to a process method for dyeing silk fabrics with vegetable dyes, in particular to dyeing silk fabrics with tea yellow pigment, which belongs to the technical field of textiles. Background technique [0002] Silk fabrics have always been the top grade in the field of clothing and are favored by consumers, especially skin-friendly clothing and home visit products. However, many chemical ingredients in chemically dyed products are harmful to the human body. The concept of returning to nature, health and comfort is getting more and more attention in the hearts of consumers. The application of natural and healthy plant dyes on silk has been re-emphasized. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a process for dyeing silk fabrics with plant dyes. damage etc. [0004] Main solution of the present invention is realized like this: [0005] A kin...
