Abstract

The invention discloses a cocoon treating method for killing cocoons by industrial salt for normal-temperature water silk reeling. The method comprises the following steps of selecting high-quality raw materials of cocoons; preparing an industrial salt water solution with the concentration being 55 to 60 percent; soaking the cocoons into the industrial salt water solution; sealing the mixture for 30 to 40d at the temperature being 30 DEG C; fishing out the cocoons from the industrial salt water solution; pouring out the industrial salt solution; cleaning the fished cocoons by clean water; charging the fished cocoons into a 50-mesh nylon bag; sealing the opening; performing spin-drying for 3 to 4min in an ordinary spin-dry barrel of a washing machine; repeating the spin-drying operation for 4 to 5 times; pouring out the cocoons; spreading the cocoons at the temperature being 25 to 30 DEG C for drying the cocoons. The fresh cocoon raw materials are subjected to cocoon killing treatment by the circularly used industrial salt solution; the environment-friendly normal temperature silk reeling production is implemented; the reelability percentage and the silk yield of the cocoons are improved; the environment pollution is reduced; the health injury to silk reeling workers caused by severe work environment is reduced; the method is simple and convenient; the silk manufacturing technical flow process is simplified; the production cost of energy source labor and the like is reduced.

Description

technical field [0001] The invention belongs to the field of silkworm cocoon processing and silk making, and relates to a method for treating silkworm cocoons and silk reeling at normal temperature by killing pupa with industrial salt used for silk reeling at normal temperature. Background technique [0002] The key of silkworm cocoon reeling is to guarantee the killing of cocoons. The current pupal killing mostly adopts traditional high-temperature pupa killing, including raw material fresh cocoon high-temperature drying treatment and freezing fresh cocoon treatment. The raw cocoons are dried at high temperature to kill pupae, and then degummed by high-temperature cooking and other procedures, and then reeled on the car. The above-mentioned process is complicated, consumes a lot of energy, the cost of the silk factory is high, and the working conditions of the silk reeling workers are harsh; although freezing pupae can simplify the process of pupae killing , Fresh cocoons ...
