The invention provides a process for spinning living cocoons, which comprises the following steps:

Sodium silicate in cocoon cooking can make water or colloid dissolved in cocoon layer precipitate, and the precipitate is not fixed on the fiber, and sodium silicate also adsorbs impurities on the fiber.

A penetration method of cocoon cooking; in order to fully swell and soften sericin, moisture must pass through the cocoon layer, and the process that water and solution enter the cocoon cavity through the cocoon layer is called penetration; drug permeation: the cocoon cooking soup is added with a small amount of surface active substances (detergent) for permeation so as to reduce the surface tension of water, increase the diffusion capacity of water molecules, have good permeation effect and reduce the cocoon cooking time.

Preferably, the cocoon cooking solution also comprises 0.1-0.5 parts by mass of surfactant.

Further, in the step S1, the cocoon cooking solution comprises the following components in parts by weight: water: 70-130 parts of sodium silicate: 1.5-3 parts of surfactant: 0.1-0.3 parts.

Preferably, in the step S2, cocoons of diapause pupae are intermittently immersed into cocoon cooking solution by adopting a cocoon cooking and bleaching device for 2-3 hours, and the temperature of the cocoon cooking solution is kept at 28-35 ℃.

In the step S3, after the step S2 is completed, continuously adding a reelability improving agent into the cocoon cooking solution, and keeping the solution temperature at 25-35 ℃ and the reelability time for 1-4 hours.

Preferably, in step S3, the said relaxing agent comprises the following components in parts by weight: hydrogen peroxide: 5-11 parts of sodium silicate: 0.8-1.6 parts of sodium carbonate: 0.6-1.3 parts.

Jie Shuji the sodium carbonate has alkaline reaction, has greasy feeling, can saponify oil and fat in cocoon layer, is easy to be soaked in water to expand and dissolve, and has the function of hydrolyzing sericin and silk fibroin.

Jie Shuji sodium silicate is easily dissolved in water, the aqueous solution of sodium silicate is alkaline, the rapid decomposition of hydrogen peroxide in alkaline solution can be restrained in the cocoon bleaching process, the effective bleaching effect is fully exerted, sodium silicate can precipitate colloid dissolved in water or cocoon shells, the precipitate is not fixed on fibers, and impurities on the fibers are adsorbed by sodium silicate, so that sodium silicate is added into the bleaching solution.

Jie Shuji the action of hydrogen peroxide (hydrogen peroxide) is relatively stable in acidic solutions and very unstable in alkaline solutions. The method has strong oxidizing property and bleaching capability, namely, the solution Shu Chuli is to remove organic pigment and inorganic impurities in the cocoon layer by utilizing the capability of hydrogen peroxide, so as to promote the dissolution and stripping of sericin; and the yellow brown pigment on the cocoon filaments is changed into colorless or brown through the bleaching effect, so that the cocoon filaments are separated Shu Lianghao.

The Jie Shuji has the properties of swelling, softening and dissolving cocoon layer sericin; the solution of the cocoon layer sericin has the functions of inhibiting and regulating; has the function of removing inorganic impurities and organic impurities in cocoon shells; less damage to the silk quality and oxidation bleaching capability; has regulating effect on hydrogen peroxide decomposition; has the advantages of penetration and washing; diffusion and emulsifying properties.

During the reelability treatment, the chemical nature of cocoons and the requirements of the reeling process are determined. Not only removing impurities in the cocoon layer to achieve reelability, but also making sericin insoluble or sparingly soluble. Therefore, both the sericin and the reelability are to be protected in the process of the reelability agent Shu Chuli and the use of the reelability agent.

In the aspect of the reelability agent, the simple alkaline substance is not used for dissolving sericin to achieve the reelability purpose, but hydrogen peroxide and the alkaline substance are used as main materials, and the surfactant is used as auxiliary material to reduce the dissolution of the sericin and remove impurities, thereby achieving the reelability purpose.

Hydrogen peroxide is more suitable for its role in alkaline solutions.

Hydrogen peroxide can remove impurities in the cocoon layer on the one hand, and can also play a bleaching role to destroy pigments in the cocoon layer on the other hand. However, bleaching is not the primary task of bleaching cocoons during de-Shu Chuli, which is the primary task of de-watering Shu Lianghao cocoons. In order to protect sericin and silk fibroin, the alkaline substance used in the solution Shu Chu is preferably a weakly alkaline substance. The surface active substance as the penetrating agent is preferably stable to alkali, acid, calcium and magnesium.

Preferably, the component of the surfactant is sodium linear alkylbenzenesulfonate.

Preferably, the components of the surfactant are detergent, at least comprising white cat detergent, libai detergent, qi Jiang Xijie detergent, super-energy detergent, mother one-step detergent, kai Mi Xijie detergent, diao detergent, blue moon detergent and the like.

Preferably, from cocoon cooking to cocoon bleaching, 5-7 hours are optimal.

Preferably, diapause pupae are stored in an environment of 2-6deg.C.

The temperature for placing the bleached cocoons is closely related to the change of the reelability. The residual bleaching liquid in the cocoon layer and the cocoon cavity with high temperature continuously plays a role in bleaching the cocoon layer, overripening can be caused by too long time, the burnt cocoons are more, the openings are more, the silk ends on the outer layer are more, the temperature is low during the placement, the cocoons after bleaching and the sericin are condensed when meeting cold, the silk ends are easy to fall, and the recovery rate is low.

The cocoon bleaching process is called as cocoon bleaching, and aims at removing impurities and pigments in cocoon layers, softening and dissolving part of sericin, so that cocoon silk can be dissociated in sequence, and silk reeling is facilitated.

The cocoon bleaching is the key of the solution Shu Chuli, the cocoon cooking quality is good, if the cocoon bleaching is improper, the cocoon layer can be damaged, the thread silk is increased, and the silk quantity is reduced.

The cocoon bleaching treatment is proper and mainly shows three aspects of reeling yield, quality and cocoon layer reeling rate.

The purpose and the requirement of cocoon cooking in the invention; the cocoon cooking is to dissolve impurities and pollutants in the cocoon layer by utilizing the actions of water, heat and medicines, so that sericin on the outer layer of cocoon silk is fully swelled, and conditions are created for cocoon bleaching. Cocoon cooking quality directly affects the quality of reelability.

When cocoon cooking, inorganic matters and pollutants in the cocoon layer are required to be fully dissolved, so that sericin is swelled and softened to be less dissolved, the silk quality is prevented from being damaged, and each part of the cocoon layer is uniformly cooked.

The cocoon cavity water absorption and the cocoon layer penetration are carried out simultaneously, and the water absorption amount is mainly determined by the penetration degree in the cocoon cooking process.

Diapause is a physiological phenomenon that arthropods such as tussah develop during their phylogenetic processes to form a physiological genetic characteristic, and develop or reproduce temporarily suspended during their life history.

Diapause is distinguished from dormancy, which is caused directly by adverse environmental conditions and can be prevented from occurring by appropriate environmental conditions, and can be promptly released.

Diapause is caused by environmental conditions at a certain development stage before diapause, and after diapause, diapause is entered, diapause must be relieved under strict environmental conditions; the metaplasia is a characteristic of the number of generations of insects such as tussah that occur in one year under natural conditions. Factors influencing diapause and chemical nature of tussah include illumination, temperature, nutrition, etc.
