Real silk dyeing method

Abstract

The invention discloses a real silk dyeing method, and relates to the dyeing process, in particular to a dyeing process of real silk fabric. The method comprises the steps of pretreatment, pre-medium dyeing, dyeing, cold water washing, deionized water washing and drying, wherein the mordant is ferrous sulfate; the natural pigment is tea tree fruit pigment. The method has the benefits that the process is simple; the coloring is uniform; the fixation effect is good; the acid-alkali degree is moderate; damage on fabric during dyeing is avoided; the operation is safe and healthy; the quality of dyed real silk fabric can be improved.

Description

Technical field: [0001] The invention relates to a fabric dyeing process, in particular to a silk dyeing method. Background technique: [0002] Silk generally refers to silk, including mulberry silk, tussah silk, castor silk, cassava silk, etc. Real silk is called the queen of fibers and has been favored by people throughout the ages for its unique charm. Silk is a protein fiber. Silk fibroin contains 18 kinds of amino acids that are beneficial to the human body, which can help the skin maintain the metabolism of the lipid film on the surface, so it can keep the skin moist and smooth. [0003] Silk fiber is the only natural filament fiber that has been practically used, and it is made by coagulating the mucus of silkworms. Silk fiber is divided into many types due to the different feeding habits of silkworms, including mulberry silk fiber formed by eating mulberry leaves, tussah silk fiber formed by eating oak leaves, and other wild silk fibers formed by eating cassava leav...

Problems solved by technology

[0005] When dyeing real silk, it is easy to be hydrolyzed, decomposed, and brittle under alkaline conditions. If it encounters alkali and high temperature, the real silk will gradually lose its strength and eventually dissolve in the alkaline solution. At present, most silk fabrics are difficult to dye. The color is easy to be uneven, and the color difference is large. Many chemical components in dyed products are harmful to the human body. The application of natural and healthy dyeing on silk has attracted people's attention.
