Embodiment 1

[0034] Dip the natural colored silkworm silk fabric in a mixed aqueous solution containing 0.5 g / L of glacial acetic acid, 1 g / L of triethylene glycol, 10 g / L of sodium 2-pyrrolidone-5-carboxylate, and 0.5 g / L of dodecyl glucoside. Rolling, the rolling ratio is 80%, and then steaming for 10 minutes in a steam box with a temperature of 100° C. and a humidity of 80%.

Embodiment 2

[0036] The natural colored silkworm silk fabric is dipped twice in the mixed aqueous solution containing 1g / L of glacial acetic acid, 2g / L of triethylene glycol, 15g / L of sodium 2-pyrrolidone-5-carboxylate, and 1.5g / L of dodecyl glucoside. , the excess ratio of 95%, and then steamed for 35 minutes at a temperature of 100°C and a humidity of 100% in a steam box.

Embodiment 3

[0038] The natural colored silkworm silk fabric is dipped and rolled twice in a mixed aqueous solution containing 1.5g / L of glacial acetic acid, 4g / L of triethylene glycol, 22g / L of sodium 2-pyrrolidone-5-carboxylate, and 1g / L of dodecyl glucoside. , the excess ratio of 105%, and then steamed for 45 minutes at a temperature of 103°C and a humidity of 90% in a steam box.

Abstract

The invention discloses a method for increasing the color concentration of degummed natural colored mulberry silk fabrics. The method includes steps of padding natural colored mulberry silk fabrics in pigment shifting treating liquid; steaming and processing the natural colored mulberry silk fabrics; degumming the natural colored mulberry silk fabrics and then washing and drying the natural colored mulberry silk fabrics to obtain the degummed natural colored mulberry sill fabrics. The method has the advantages that crosslinking agents and grafting treatment agents are omitted, the natural colored mulberry silk fabrics are degummed by the aid of a conventional degumming process, the wearability of the degummed natural colored mulberry silk fabrics is unaffected, the fabrics are free of residual chemical reagents, and the method is free of influence on environments and human health and is ecological and environmental friendly; silk fibroins have high natural pigment contents and are colorful.

Description

technical field [0001] The invention belongs to the technical field of textile processing, and in particular relates to a method for increasing the color concentration of natural colored silkworm silk fabrics after degumming. Background technique [0002] Natural colored silk is a new variety of colored silk obtained by transferring the excellent colored cocoon genes of original species at home and abroad to high-yield and high-quality white cocoon varieties through gene recombination, and breeding high-yielding colored cocoon silkworm varieties, which are reeled. The structure of natural colored silk is the same as that of ordinary silkworm silk, consisting of sericin and silk fibroin, and sericin is coated on the outside of silk fibroin. In the process of silk fabric processing, the difference between sericin and silk fibroin can be used to peel off sericin from silk fibroin, so that the silk fabric presents natural soft luster, good permeability, soft and comfortable text...
