Embodiment Construction

[0015] Below in conjunction with embodiment the present invention is further described:

[0016] Utilize protease, lipase to comprise the following steps in the process of making mulberry silk product:

[0017] 1. Presoaking: Use warm water at 55°C, adjust the pH value to 10 with soda ash, add soap with 0.75% of dried cocoon, add protease 6543# with about 0.5% of dry cocoon, and mix well to become a degumming presoaking solution; remove The defective cocoons or sticks after debris are mixed with the prepreg at a liquor ratio of 1:10, and kept naturally for more than 12 hours until cooled;

[0018] 2. Opening: Take out the pre-soaked defective cocoons, rinse them with clean water, use a cocoon opener to remove the silkworm chrysalis, and loosen the defective cocoon silk layer into pieces for later use;

[0019] 3. Preliminary training: Use soda ash to adjust the pH value of the training solution to 9-10, add 0.1% soap in the training solution, control the temperature at 90°C-9...

Abstract

Application of protease and lipase to manufacture of a mulberry silk product has the following characteristics: the invention employs purified efficient alkaline lipase and protease and is accompanied with mature chemical refining method, so that silkworm cocoon or thin skin black cocoon that can not be used in silk reeling is mixed with alkaline lipase and protease, cooperated with a proper amount of surfactant, insulated naturally for 11.5-12.5 h with a bath ratio of 1:10-20 and a pH of 10.5-11 at 48-52 DEG C until cooled, taken from the pot, flushed, refined and treated with soft processing to obtain a fine draft sheet. The invention can well solve problems of degumming and oil removal in a prior silk spinning combing technology, reduce chemical raw material amount for producing per ton of silkworm fine dry draft by 2/3, save 5000 yuan of chemical material, 100 ton of water and 5 ton of coal for producing per ton of silkworm fine dry draft, promote application and popularization of industrial biological technology to silk inserts and processing of functional product, advance effective utilization and conversion increment of silk leftover and fill blanks of high quality velvet product home and abroad.

Description

technical field [0001] The present invention relates to the development of a novel protease degumming and lipase degreasing composite technology and applies this technology to the production process of functional combed silk mulberry silk and mulberry silk linters, and the functional combed mulberry silk, A complete set of production process for making silk short-staple cotton into follow-up products silk health-care pillows and silk health-care quilts. The combed silk cotton sheets processed by the present invention can fully display the natural properties of silk, and have aroma and fluffiness. High, good compression resilience, white color, long-term use without hardening and so on. The obtained cotton sheet can also be widely used in high-grade warm clothes, health-care pillows, pads, quilts, etc. as filling materials. new silk products; [0002] The technology used in the present invention is currently blank in the home textile industry. After the technology is enlarged...
