JPS59211610A - Reeling of frozen fresh cocoon - Google Patents

Abstract

PURPOSE:To secure the stable supply of raw cocoons throughout the year, and to enable the manufacture of high-quality raw silk preventing the contamination from crystalis tissue, by freezing fresh cocoons to effect the separation of water from the cocoon and the coagulation of the molecule, and carrying out the reeling of the silk. CONSTITUTION:Fresh cocoons are put into a cloth bag having a capacity of preferably about 5kg, frozen in a refrigeration chamber maintained at e.g. -25 deg.C, and reeled optionally after boiling. EFFECT:Sericin is frozen and removed while leaving the fibroin constituting the cocoon filament unchanged. Accordingly, the peel resistance of the cocoon filament can be decreased, the reeling property is improved, and soft and snow white raw silk having excellent color and luster can be obtained easily.

Description

T: Yes.

(a) It is possible to store the yarn through time and effort, and the yarn can be reeled with even time and effort.

During the storage of cocoons, the tubs do not deteriorate or oxidize.

Then, when the silk is reeled, the body fluids containing proteins, nitrogen compounds, and fat particles that form the transfusions are dissolved into the cocoon and the cocoon layer. contaminate.

There are contacts at a rate of about 1 per 1 h in the haze layer, and V contacts μ0.2 to Q, 31111 are in contact with each other. However, depending on the humidity during cocooning and the health condition of the silkworms, the difference in the welts becomes large, and it is possible for the silk to stop spinning or even stop spinning. Average-T: Yes. Therefore, it is disadvantageous to reel the raw cocoon 7) once.

Try not to get close to F.

Dry the surface by heating and drying the melon. When dried by heat, nitrogen compounds are decomposed from the complement during killing, and as a result of the decomposition of gropion and protein xD, water vapor containing fine particles such as gutsin, cadaverine, and fat is absorbed into the cocoon layer. .

The 7-1IA threads from the cocoon layer and the fibroin around the 7D layer form a magnetic layer.

It is a very active hunter, and a suitable partner is often found there. Therefore, if there is an impure proboscis in the filtrate, it will be absorbed by the layer F, and if it is dried, the cocoon thread will be absorbed.

Sericin is made up of a filamentous molecule and a single molecule D. Branch 7) It is made up of parts that can be purchased depending on the front foot.

The second object of the present invention is achieved by reducing the peeling resistance of the cocoon fibers and improving unwinding.

There is a frozen raw 111IjD reeling method in which sericin and complement are agglomerated and dehydrated by lowering the concentration of tin around C, and the reeling raw material surface is ensured throughout the process to produce uniform high-quality raw silk.
