Embodiment 1

[0019] A method for improving the unwinding rate of raw silk, comprising the steps of:

[0020] S1. Put silkworm cocoons in a microwave cocoon drying machine, control the temperature at 55°C, adjust the microwave frequency to 2600MHz, and feed microwaves from the top of the microwave cocoon drying machine, and the drying time is 12 minutes;

[0021] S2, the temperature is raised to 90°C, and the drying time is 8 minutes;

[0022] S3, cool down to 55°C, and dry for 12 minutes; distribute the moisture between the cocoon layer and the pupae, eliminate part of the sericin attached to the cocoon, and achieve a balanced effect;

[0023] S4. Cool down to below 40°C, and continue drying for 6 minutes to produce cocoons;

[0024] S5. Place the silkworm cocoons obtained in step S4 in a vacuum infiltration device, and then allow the permeate to flow into the vacuum infiltration device through negative pressure after vacuuming. The mass ratio of the permeate to the silkworm cocoon is 10:...

Embodiment 2

[0030] A method for improving the unwinding rate of raw silk, comprising the steps of:

[0031] S1. Put silkworm cocoons in a microwave cocoon drying machine, control the temperature to 75°C, adjust the microwave frequency to 2300MHz, and feed microwaves from the top of the microwave cocoon drying machine, and the drying time is 7 minutes;

[0032] S2, heating up to 115°C, drying time is 5 minutes;

[0033] S3, cool down to 85°C, and dry for 7 minutes; distribute the moisture between the cocoon layer and the pupae, eliminate part of the sericin attached to the cocoon, and achieve a balanced effect;

[0034] S4. Cool down to below 40°C, and continue drying for 3 minutes to produce cocoons;

[0035] S5, place the cocoons obtained in step S4 in a vacuum infiltration device, and then allow the permeate to flow into the vacuum infiltration device through negative pressure after vacuuming, the mass ratio of the permeate to the cocoon amount is 15:1, and the vacuum degree is 0.09Mpa...

Embodiment 3

[0041] A method for improving the unwinding rate of raw silk, comprising the steps of:

[0042] S1. Put silkworm cocoons in a microwave cocoon drying machine, control the temperature at 65°C, adjust the microwave frequency to 2450MHz, and feed microwaves from the top of the microwave cocoon drying machine, and the drying time is 9.5 minutes;

[0043] S2, the temperature is raised to 102.5°C, and the drying time is 6.5 minutes;

[0044] S3, cooling down to 70°C, drying time is 9.5 minutes; distributing the moisture between the cocoon layer and the pupa, eliminating part of the sericin attached to the cocoon, to achieve a balanced effect;

[0045] S4. Cool down to below 40°C, and continue drying for 4.5 minutes to produce cocoons;

[0046] S5. Place the silkworm cocoons obtained in step S4 in a vacuum infiltration device, and then allow the permeate to flow into the vacuum infiltration device through negative pressure after vacuuming. The mass ratio of the permeate to the silkw...

Abstract

The invention discloses a method for increasing reelability percentage of raw silk. According to the scheme, ficin is adopted, the problems that the energy consumption is high and environment pollution and low raw silk quality are brought by chemical aids and the like in a traditional high-temperature cocoon cooking process can be solved, and the cocoon cooking effect can be effectively improved. After silk reeling, the measured average reelability percentage can be up to 78.9 percent, the cocoon reeling ratio is reduced by over 5 percent, the treatment process is simple, and has the energy-saving and environment-friendly effects, and the obtained silk is good in color.

Description

technical field [0001] The invention relates to the field of textile production, in particular to a method for improving the unwinding rate of raw silk. Background technique [0002] Silk is obtained by weaving real silk, and real silk is processed by reeling silkworm cocoons and boiling cocoons. The silk reeling and cocoon cooking process mainly includes cocoon mixing, cocoon peeling, cocoon selection, cocoon cooking, silk reeling, reshaking, and finishing. Among them, the cocoon cooking process is to make use of water, heat or chemical additives to make the cocoon silk glue point sericin properly swell and soften, reduce the adhesive force between the cocoon silk, and make the cocoon silk dissociate sequentially to meet the requirements of reeling. silk production requirements. Different cocoon cooking techniques and technical measures are used in silk reeling production, which have a great impact on the quality of reeled silk. Only when cocoons are cooked well can silk ...
