Abstract

The invention discloses an initial refining process of macular cocoons, which is characterized in that the initial refining process is performed according to the following steps: soaking the macular cocoons in water solution at the temperature of 100 DEG C, using soda ash to regulate pH value to 10, soaking for 12 hours, soaking the macular cocoons after removing pupae in the water solution at the temperature of 60 DEG C, using the soda ash to regulate the pH value to 7.5, soaking for 10-12 hours, using a scutching machine to scutch the wet macular cocoons after low-temperature soaking, placing cocoon filaments after dehydration into the water solution at the temperature of 60-70 DEG C, adding hydrogen peroxide for bleaching, placing the cocoon filaments after bleaching into a refining cylinder, adding water, heating with steam to 60-70 DEG C, adding 105 textile soap solution which accounts for 2% of the weight of raw materials for refining for 1 hour, flushing the well refined cocoon filaments by using an automatic flushing machine, adding water for soaking the cocoon filaments after dehydration, adding a spun silk finishing agent which accounts for 4% of the weight of the raw materials, soaking for half an hour, drying the cocoon filaments after dehydration with the steam, selecting and removing impurities in the cocoon filaments after drying, and classifying.

Description

technical field [0001] The invention relates to a treatment of fabric fibers, in particular to a primary refining process for macular cocoons. Background technique [0002] As we all know, although my country is a big cocoon-producing country, the annual cocoon production accounts for 72% of the world's total, but due to the different production areas and other factors in the cocoon production process, the cocoons suitable for silk reeling factories that can be used as factory silk only account for 72% of the world's total. About 70% of the total output, about 30% silkworm cocoons, mainly macular cocoons have been used for silk spinning production. At present, in silk spinning production, the treatment of macular cocoons has always been the traditional fermentation process. This process has problems such as long assembly line, long cycle, large labor consumption, high work intensity, and large sewage discharge. Among them, only the corrosion process It takes 60 to 72 hours. ...
