Abstract

The invention belongs to the technical field of silk degumming, and discloses a low-temperature degumming agent for natural colored silk and a degumming method of the low-temperature degumming agent.The low-temperature degumming agent is prepared from, by weight, 3-6 parts of saponin, 1-2 parts of a semen hoveniae extract, 1-4 parts of polyoxyethylene ether, 1-3 parts of paeoniflorin, 3-5 parts of betaine, 1-10 parts of ethanol and 75-90 parts of water. By adopting the low-temperature degumming method for silk degumming, the energy is saved. Pigments in the natural colored silk can also be prevented from being destroyed by high temperature, and the natural colored silk is prevented from color fading. According to the silk degumming agent, since degumming components with the lower molecular weight are selected and various components which improve the permeability and degumming effect of the degumming agent are selected, the degumming process is more convenient, and the degumming effectis better. The degummed silk has antibacterial functionality and can be endowed with good antibacterial properties after the low-temperature degumming agent is applied.

Description

technical field [0001] The invention belongs to the field of silk degumming, in particular to a low-temperature degumming agent for natural colored silk and a degumming method thereof. Background technique [0002] The degumming of silk fiber fabric is the main content of refining. The composition of silk includes sericin and silk fibroin, and its purpose is to remove sericin, wax fat, pigment, etc. wrapped in its outer layer. Commonly used degumming agents include soap, proteolytic enzymes, and surfactants; the alkali agents used include sodium hydroxide, sodium carbonate, and sodium silicate. Degumming methods include chemical degumming, microbial degumming and enzymatic degumming. The principle of chemical degumming is to use the difference in the stability of sericin and silk fibroin to chemical agents such as alkalis and inorganic acids to remove sericin. Sericin is easier to be hydrolyzed than silk fibroin to form water-soluble compounds, which are removed by washing...
