Problems solved by technology

[0002] The traditional method of dyeing silk fabrics is to use soap-alkali method for degumming. Alkali degumming requires high temperature. In addition to easily causing yellowing and damage to silk fibroin, the boiling of the training liquid can cause friction between silks and cause abrasions. , hair and other blemishes, stains are also easy to form when dyeing
Therefore, there are currently many production processes that use biological enzyme technology to refine silk fabrics. Although this process can be degummed to a certain extent at a lower temperature, the problem of unstable biological enzyme activity leads to low degumming efficiency. Guarantee the performance stability of the product

Abstract

The invention discloses a low-temperature pre-treatment method of a real silk textile. The low-temperature pre-treatment method comprises the following steps: (1) carrying out alkali liquid pre-treatment; (2) washing with warm water; (3) washing with cold water; (4) degumming with acidic protease; (5) carrying out counter-current washing in warm water; (6) sizing and airing. According to the low-temperature pre-treatment method disclosed by the invention, efficient degumming of the real silk textile can be realized at relatively low temperature, so that the quality in all aspects of the real silk textile can be improved.

technical field [0001] The invention relates to a low-temperature pretreatment method for real silk fabrics, which belongs to the technical field of textile treatment. Background technique [0002] The traditional method of dyeing silk fabrics is degumming by soap-alkali method. Alkali degumming requires a high temperature. In addition to easily causing yellowing and damage to silk fibroin, the boiling of the training liquid can cause friction between silks and cause abrasions. , Hair and other defects, it is also easy to form stains when dyeing. Therefore, there are currently many production processes that use biological enzyme technology to refine silk fabrics. Although this process can be degummed to a certain extent at a lower temperature, the problem of unstable biological enzyme activity leads to low degumming efficiency. Guarantee the performance stability of the product. Contents of the invention [0003] The object of the present invention is to provide a low-te...
