Problems solved by technology

If you want to obtain silk, you must remove the sericin in its ingredients. Now the market generally uses hot water to boil the cocoons, and at the same time make the water alkaline, which is conducive to the quality of the final product. However, this method in the market now costs Higher, there are certain obstacles to the development of small and medium-sized enterprises

Embodiment 1

[0019] A silkworm cocoon reeling process, comprising the following sequential steps:

[0020] (1), silkworm cocoon selection: select the spring cocoon 8 hours after the cocoon, and the summer and autumn cocoon 6 hours after the cocoon;

[0021] (2) Refrigeration and freezing: Put the selected fresh cocoons into the cold storage, quickly cool down to -10°C, then slowly raise the temperature to -5°C, keep the temperature and refrigerate for 15 hours;

[0022] (3) Cocoon mixing, cocoon peeling, and screening: the silkworm cocoons after refrigeration and preservation are mixed first, and then peeled and screened;

[0023] (4) Vacuum infiltration: put the screened silkworm cocoons into a vacuum box, evacuate them, then add water to the vacuum box, the water also includes sodium hydroxide, the ratio of sodium hydroxide to water is 0.1:100, vacuum Osmosis control The vacuum degree of pumping is 94kPa, after adding water, the vacuum degree is 93kPa, the water temperature is 48°C, pH ...

Embodiment 2

[0026] A silkworm cocoon reeling process, comprising the following sequential steps:

[0027] (1), silkworm cocoon selection: select the spring cocoon 7 hours after the cocoon, and the summer and autumn cocoon 5 hours after the cocoon;

[0028] (2) Refrigeration and freezing: Put the selected fresh cocoons into the cold storage, quickly cool down to -15°C, then slowly raise the temperature to -7°C, keep the temperature and refrigerate for 10 hours;

[0029] (3) Cocoon mixing, cocoon peeling, and screening: the silkworm cocoons after refrigeration and preservation are mixed first, and then peeled and screened;

[0030] (4) Vacuum infiltration: Put the silkworm cocoons screened into a vacuum box, vacuumize, then add water to the vacuum box, the water also includes surfactant, the ratio of surfactant to water is 0.1:100, vacuum Osmosis control The vacuum degree of pumping is 92kPa, after adding water, the vacuum degree is 84kPa, the water temperature is 42°C, pH7.5, vacuum infil...

Embodiment 3

[0033] A silkworm cocoon reeling process, comprising the following sequential steps:

[0034] (1), silkworm cocoon selection: select the spring cocoon 7.5 hours after the cocoon, and the summer and autumn cocoon 5.5 hours after the cocoon;

[0035] (2) Refrigeration and freezing: Put the selected fresh cocoons into the cold storage, quickly cool down to -13°C, then slowly raise the temperature to -6°C, keep the temperature and refrigerate for 13 hours;

[0036] (3) Cocoon mixing, cocoon peeling, and screening: the silkworm cocoons after refrigeration and preservation are mixed first, and then peeled and screened;

Abstract

The invention relates to the technical field of silk cloth production and discloses a silkworm cocoon reeling process, comprising the steps: (1) selection of silkworm cocoons; (2) cold storage and refrigeration; (3) mixing, stripping and sieving of cocoons; (4) vacuum penetration; and (5) reeling. The silkworm cocoon reeling process is high in reelability of cocoon silks and low in cost; refrigeration and reeling of fresh cocoons are utilized, so that silk gum molecules are changed physically and the property of the silk gum is not changed; the silkworm cocoon reeling process is high in yielding, increased in benefits and high in utilization of by-products.

Description

technical field [0001] The invention relates to the technical field of silk production, in particular to a cocoon reeling process. Background technique [0002] my country is an ancient country of silk. Chinese silk fabrics have been famous all over the world since Leizu, the concubine of the Yellow Emperor, invented the silk reeling process four thousand years ago. After Zhang Qian went to the Western Regions, the trade of silk products from China began to spread to Europe. They regarded buying and wearing silk as a symbol of wealth and status. The silk reeling equipment has developed from seat reeling, vertical reeling to automatic reeling, but the traditional production process is still used in the silk reeling process, and the process flow is basically the same as the silk reeling process invented by Leizu. [0003] At present, my country's cocoon and silk production scale ranks first in the world, with an annual output of about 500,000 tons of silkworm cocoons and more...
