Method of rejecting secondary cocoon during silk reeling and using secondary cocoon produce silk floss

A silk wool and process technology, applied in the field of removing secondary cocoons and processing silk wool, can solve the problems of adding and falling again, unbalanced, poor arrangement, etc., so as to improve the unwinding rate, reduce the cost of silk reeling, and reduce the thread loss. The effect of reducing the number of cocoons

Problems solved by technology

During this period, some silkworm cocoons had to be threaded when they were broken. A lot of practice found that the cocoons were not normally distributed, but concentrated on a few mischievous cocoons. It was also found that the inner and middle layers of the cocoon are caused by the low arrangement degree of silk fibroin molecules in this part, and most of them will fall when the tension is extremely small. The arrangement degree is also poor, and it is not balanced, and some are even worse, so Often there will be a phenomenon of adding and falling

Embodiment Construction

[0007] The method for removing secondary cocoons in silk reeling and processing silk wool from secondary cocoons according to the present invention includes cocoon cooking, spinning, threading and thread winding processes, and is characterized in that the threading process is provided with picking and removing the cocoons. step.

[0008] The above-mentioned cocoons are loosened, boiled, degummed, washed, dried and combed to make silk wool with soft fibers.

[0009] The silk wool obtained by the above method has uniform tension of longitudinal and transverse fibers and is distributed in a natural state. It can be used to make cotton jackets or cotton vests to maintain the curvaceous body. It has a good effect on preventing ultraviolet radiation, and it is also an ideal raw material for making silk umbrellas and hats.

[0010] After a long-term study, it was found that the middle and inner layers of the cocoon fell due to the low degree of arrangement of silk fibroin molecules ...

Abstract

A technology for rejecting the secondary cocoons in the silk reeling procedure includes such steps as boiling cocoons, drawing silk, brushing including the step of rejecting the dropping end cocoons, and reeling. Said dropping end cocoons can be used to prepare soft silk floss through loosening, boiling degluing, water washing, baking and carding.

Description

technical field [0001] The invention belongs to the technical field of silk fiber production, in particular to a method for removing secondary cocoons in silk reeling and processing silk wool from secondary cocoons Background technique [0002] Silk reeling is the main process of the silk making process. It extracts the cocoon silk from several cooked cocoons and combines them into raw silk or tussah silk according to the product specifications. The cocoon filaments are combined and passed through the thread collector, and then form a silk sheath, which leads the silk to be wound on the filament winding frame and dried. During this period, some silkworm cocoons had to be added when their heads were broken. A lot of practice found that the lost thread cocoons were not normally distributed, but concentrated on a few troublesome cocoons. These cocoons will soon fall off as soon as the thread reaches the thread. It was also found that the middle and inner la...
