Problems solved by technology

This method is also degummed under alkaline conditions, which will damage the silk fibers to a certain extent. In order to effectively remove oil and impurities, an additional alternating magnetic field is required during the fermentation process. The preparation process is complicated and difficult to operate in the actual process.

Embodiment 1

[0038] (1) Take the silkworm cocoon and open the cocoon to remove the silkworm chrysalis in the silkworm cocoon;

[0039] (2) Put the silkworm cocoon (100g) after cocoon opening in 1000g neutral aqueous solution, raise the temperature to 100°C, keep it at 100°C for 30 minutes, then cool down to 96°C and keep it warm for 2 hours to degumming and decomposing silk protein on the cocoon ; Wherein, the neutral aqueous solution is prepared by dissolving the Pluronic F-127 surfactant of 15g in 985g water;

[0040] (3) Cool down to 40-45°C, add 15g of active enzyme and 20g of soaking soda to the system in step (2), and keep it warm for 48 hours to ferment and decompose;

[0041] (4) After the fermentation and decay, the silk fiber is drawn out, and the silk fiber can be obtained after the silk fiber is opened, washed, dehydrated, and dried; The supernatant is concentrated and then freeze-dried to obtain the silk protein.

[0042] The silk fiber after fermenting and decomposing in th...

Embodiment 2

[0044] (1) Take the silkworm cocoon and open the cocoon to remove the silkworm chrysalis in the silkworm cocoon;

[0045] (2) Put the silkworm cocoons (100g in total) in 1000g of neutral aqueous solution, raise the temperature to 100°C, and cook at 100°C for 30 minutes, then cool down to 96°C and keep it warm for 2 hours to degumming the silk protein on the silkworm cocoons Decomposition; wherein, the neutral aqueous solution is prepared by dissolving 20g of sodium glycocholate surfactant in 980g of water;

[0046] (3) Cool down to 40-45°C, add 20g of active enzyme and 20g of soda to the system in step (2), and keep it warm for 48 hours to ferment and decompose;

[0047] (4) After the fermentation and decay, the silk fiber is drawn out, and the silk fiber can be obtained after the silk fiber is opened, washed, dehydrated, and dried; The supernatant is concentrated and then freeze-dried to obtain the silk protein.

[0048] The fermented silk fibers in this example were drawn ...

Abstract

The invention relates to a preparation method of silk cotton. The method comprises the following steps of putting silkworm cocoons into a neutral solution for degumming, and fermenting and rotting the degummed silkworm cocoons under the action of active enzyme and sodium silicate. Through the design of the degumming process and the fermenting and rotting process, the damage to the silk cotton is reduced, degumming can be efficiently carried out, and the peculiar smell of silk fibers can be effectively removed, so that the prepared silk cotton has the advantages of being good in strength, good in filling power, good in glossiness and free of peculiar smell.

Description

technical field [0001] The invention relates to a preparation method of silk cotton. Background technique [0002] Silk is the fiber that solidifies after the silk liquid in the silkworm body is spit out. Silk is mainly composed of silk fibroin, sericin wrapped in the outer layer of silk fibroin, pigment, oil wax and inorganic substances. In order to ensure the fluffy, clean and soft silk cotton, it is necessary to remove most of the sericin, grease, wax and other sundries on the silk cotton. [0003] Chinese patent CN200610050727.6 obtains elastic silk fiber by soaking cocoons in boiled soda ash aqueous solution, cocoon opening, impurity removal, cotton opening, and high-temperature steam contact steaming. Although this method can obtain silk floss fibers with certain elasticity, the use of soda ash will reduce the glossiness and fiber strength of the silk floss fibers. Chinese patent CN201811085845.X uses immobilized microbial strains to ferment deoil and remove impurit...
