Abstract

The invention relates to the field of silk processing, and particularly discloses a degumming agent, a preparation method of the degumming agent, a silkworm cocoon degumming method and application. The degumming agent comprises the following raw materials: soybean phospholipid, sorbitan fatty acid ester, polyoxyethylene anhydro sorbitan monooleate, alkyl alcohol polyoxyethylene ether, alkyl polyglucoside and ethylene glycol. The degumming agent provided by the invention has an excellent degumming effect; due to adoption of a biodegradable surfactant, generated degumming wastewater generated inthe degumming process can be further deep-processed into a sericin protein product, and also can be directly used as a fertilizer, so that secondary pollution for the environment can be avoided; anda degumming rate of the silk degumming method provided by the invention can reach over 10%, production requirements of the silk industry can be met, degummed silk can be used for researching and developing foods, cosmetics or medicines, an application range of silk products is further exploited, and a problem that an existing silkworm cocoon degumming method is liable to cause pollution for the environment is solved.

Description

technical field [0001] The invention relates to the field of silk processing, in particular to a degumming agent and a preparation method thereof, a silkworm cocoon degumming method and application thereof. Background technique [0002] Silk is a natural protein fiber composed of silk fibroin and outer layer sericin, which has excellent moisture absorption performance, heat preservation performance, flame retardant performance and sterilization and deodorization effect. Therefore, silk products (silk products) are very popular among consumers. [0003] In the silk processing industry, the first process of silk processing is to separate silk fibroin from sericin, which is called degumming in the industry. At present, the degumming methods in industrial production mainly include methods such as high-pressure and high-temperature degumming, alkali boiling, chemical degumming and acidic degumming. [0004] However, high-pressure and high-temperature degumming consumes a lot of...
