Silk Yarn Production Process


Raw materials

The main materials are silk fiber, Spools, cops, reels and cons.

Production Process

Hatching of eggs

Sericulture, or the raising of silkworms, involves the incubation of the tiny eggs of the silk worm moth until they hatch and becomes worms. After hatching, the worms are placed under a layer of gauze, on which is spread a layer of finely chopped mulberry leaves. For six weeks, the worms eat almost continuously. At the end of this period, they are ready to spin their cocoons, and branches of trees or shrubs are placed in their rearing houses.

Silk Production

The worms climb these branches and make their cocoons in one continuous thread, taking about eight days for the process. The amount of usable silk

Citric acid production process

Citric acid can be extracted from the juice of citrus fruits, by fermentation of glucose with the aid of the mold Aspergillus niger and synthetically from acetone or glycerol. 
 

Today, essentially all of the commercial citric acid is produced by fermentation. Processes employed are surface or submerged fermentation by mold (Aspergillus niger) and submerged fermentation by yeast
