Embodiment 1

[0025] A clean silkworm cocoon cooking cocoon method, comprising the following steps:

[0026] S1. Put the selected silkworm cocoons in the self-made soaking agent, soak for 3 hours at 30°C, and rinse with water for 6 minutes. The soaking agent should cover 1cm of the fresh cocoons;

[0027] S2. Dry the silkworm cocoons rinsed with clean water with microwaves and far-infrared light waves, and then send them into steam for contact steaming. The steam contact steaming is divided into three stages. The first stage maintains a pressure of 6Mpa, a temperature of 65 degrees Celsius, and a time of 6 hours. The stage maintains a pressure of 9Mpa, a temperature of 95 degrees Celsius, and a time of 12 hours. The third stage maintains a pressure of 3Mpa, a temperature of 70 degrees Celsius, and a time of 8 hours;

[0028] S3. In the vacuum cocoon cooking infiltration device, add 0.8Kg of release agent to 100Kg of infiltration cocoon boiling water, and then put in 5Kg of cocoons after con...

Embodiment 2

[0032] A clean silkworm cocoon cooking cocoon method, comprising the following steps:

[0033] S1. Put the selected silkworm cocoons in the self-made soaking agent, soak for 2 hours at 40°C, and rinse with water for 12 minutes. The soaking agent must cover 1cm of the fresh cocoons;

[0034] S2. Dry the silkworm cocoons rinsed with clean water with microwaves and far-infrared light waves, and then send them into steam contact steaming. The steam contact steaming is divided into three stages. The first stage maintains a pressure of 9Mpa, a temperature of 95 degrees Celsius, and a time of 5 hours. The stage maintains a pressure of 11Mpa, a temperature of 115 degrees Celsius, and a time of 10 hours. The third stage maintains a pressure of 5Mpa, a temperature of 90 degrees Celsius, and a time of 7 hours;

[0035]S3. In the vacuum cocoon cooking infiltration device, add 1.8Kg of relief agent to 100Kg of infiltration cocoon boiling water, and then put in 10Kg of cocoons after contact...

Embodiment 3

[0039] A clean silkworm cocoon cooking cocoon method, comprising the following steps:

[0040] S1. Put the selected silkworm cocoons in a self-made soaking agent, soak for 2.5 hours at 35°C, and rinse with water for 9 minutes. The soaking agent must cover 1cm of fresh cocoons;

[0041] S2. Dry the silkworm cocoons rinsed with clean water with microwaves and far-infrared light waves, and then send them into steam for contact steaming. The steam contact steaming is divided into three stages. The first stage maintains a pressure of 7.5Mpa, a temperature of 80 degrees Celsius, and a time of 5.5 hours. In the second stage, the pressure is kept at 10Mpa, the temperature is 100 degrees Celsius, and the time is 11 hours; in the third stage, the pressure is kept at 4Mpa, the temperature is 80 degrees Celsius, and the time is 7.5 hours;

[0042] S3. In the vacuum cocoon cooking and infiltration device, add 1.3Kg of relief agent to 100Kg of infiltration cocoon boiling water, and then put...

Abstract

The invention discloses a clean silkworm cocoon cooking method. The method comprises the following steps: putting selected silkworm cocoons in a home-made soaking agent to be soaked, then washing the silkworm cocoons with clear water and drying the silkworm cocoons by microwave and far infrared optical wave and then sending the silkworm cocoons to be directly steamed; putting the silkworm cocoons in a vacuum cocoon cooking permeator after direct steaming is completed, adding proper amount of unwinding agent, controlling the water temperature at 30-50 DEG C, carrying out vacuum permeation, and when the vacuum pressure is -0.1Mpa, taking out the silkworm cocoons to enter the next cocoon cooking procedure after continuing for 1-5 minutes, after cocoon cooking is completed, putting the obtained silkworm cocoons in a fast freezing tank at 23 DEG C to be fast frozen for seven hours, then putting the silkworm cocoons in an environment at minus 10.5 DEG C and with vacuum degree of 270pa to be sublimated for 230 minutes and sending the silkworm cocoons to a silk reeling workshop. The method has the beneficial effects that by adopting the cocoon cooking method to cook cocoons, the obtained cooked cocoons have high silk yields and good quality; the quality indicator levels of the cooked cocoons are greatly improved; the cleaning, strength and cohesion indexes are improved by more than or equal to one grade.

Description

technical field [0001] The invention relates to textile engineering technology, in particular to a clean cocoon cooking method. Background technique [0002] With the development of science and technology, especially the application of new equipment such as high-speed looms in weaving, new requirements have been put forward for the quality of raw silk: to improve the strength, cohesion, cleanness and cleanliness of raw silk, so that it can adapt to the high tension of high-speed looms , Strong friction requirements. To meet such requirements, the cocoon cooking process of raw silk plays an important role in the reeling process. Cocoon cooking is a key process in the silk making process. The quality of cocoon cooking not only directly affects reeling and unwinding, but also affects deviation, cleaning, cleaning, cohesion of raw silk, average fineness of raw silk, etc., and the quality of raw silk. related indicators. In silk reeling production, only in the cocoon cooking p...
