Problems solved by technology

[0002] The traditional pre-dyeing method of silk fabric is degumming by soap-alkali method, but the temperature required for degumming by soap-alkali method is high, which is easy to cause yellowing and damage of silk fibroin. And the degumming of the soap and alkali method makes the degumming of the inner and outer layers of the silk fabric uneven
Therefore, the traditional pre-dyeing method of silk fabrics has the problems of yellowing and damage of silk fibroin, scratches and hairs of fabrics, and uneven degumming of inner and outer layers of silk fabrics.

Abstract

The invention discloses a dyeing pretreatment method for a real silk fabric. The dyeing pretreatment method comprises the following steps: (A) pretreating by virtue of a sodium carbonate solution, soas to obtain a product A; (B) washing the product A, so as to obtain a product B; (C) degumming the product B with an acid protease solution, so as to obtain a product C; (D) rinsing residual gum in the product C with a rinsing agent, so as to obtain a product D; and (E) washing the product D, wherein the percentage concentration of acid protease is 1%-5%, the pH value is adjusted to 5.5-6.5, thebath ratio of the real silk fabric to the sodium carbonate solution is 1 to (20-40), the degumming temperature is 50-60 DEG C, and the degumming time is 30-45 minutes. The dyeing pretreatment method has the characteristics that fibroin does not yellow and is not damaged, the fabric is not scratched, the pilling is avoided, and inner and outer layers of the real silk fabric are uniformly degummed.

Description

technical field [0001] The invention relates to a method for pre-dyeing silk fabrics. Background technique [0002] The traditional pre-dyeing method of silk fabric is degumming by soap-alkali method, but the temperature required for degumming by soap-alkali method is high, which is easy to cause yellowing and damage of silk fibroin. And the degumming of the soap alkali method makes the degumming of the inner and outer layers of the real silk fabric uneven. Therefore, the traditional pre-dyeing treatment method of silk fabrics has the problems of yellowing and damage of silk fibroin, scratches and hairs of the fabric, and uneven degumming of the inner and outer layers of the silk fabric. Contents of the invention [0003] The object of the present invention is to provide a method for pre-dyeing silk fabrics. The invention has the characteristics that the silk fibroin is not yellowed or damaged, the fabric is not scratched or hairy, and the inner and outer layers of the s...
