Embodiment Construction

[0037] According to the investigation of silk characteristics and process design requirements, the specific steps of vacuum hot water infiltration are as follows:

[0038] 1. Fresh cocoons are refrigerated, and the temperature is controlled at -6~-12°C;

[0039] 2. To cocoon. Put the cocoon into a stainless steel mesh basket, put it into a vacuum tank, and close the lid tightly. Close the inlet valve and drain valve. (The amount of cocoons added each time depends on the scale of production)

[0040] 3. Vacuuming for the first time. Start the vacuum pump, open the exhaust valve to pump air for about 2-4 minutes, and close the exhaust valve after the vacuum degree is 0.08-0.09MPa.

[0041] 4. Enter hot water. First use an electric heating tube to heat the water to 58°C to 60°C. After opening the water inlet valve, fill the vacuum tank with hot water. The pH value of the hot water is maintained at 7.2 to 7.5. The water inlet height is 4-6cm higher than the cocoon.

Abstract

A cold storage method without boiling for reeling silk includes cold storage of fresh cocoon, loading in netted basket, putting in vacuum tank, vacuumizing, hot water osmosis, discharging water and repeating relative steps. Its advantages are high efficiency and high quality.

Description

technical field [0001] The invention relates to the technical field of silk production in the textile industry, and more particularly relates to a method for long-term refrigeration of fresh cocoon reeling without cooking cocoons. Background technique [0002] In the current silk production process, cocoon cooking is a necessary process. The function of cocoon boiling is to make the sericin of silkworm cocoons that have been dried for "quality preservation" and storage needs to absorb water again, so that the glue points of the silk strands can be separated in an orderly manner during reeling, and the cocoon silk can be reeled smoothly and continuously to form raw silk. [0003] At present, most of the industry regards the cocoon cooking process as the "bottleneck" in each process of silk reeling. The key link with high technical difficulty in the factory. So far, the reform of the cocoon cooking process is basically a variety of local improvements...
