Crinkly fabrics are made with crepe, while sheer cloth is made with single thread. In the reeling process, a special wooden device is used to locate the end of the filament, after which it must be carefully unwound, a process that not only requires hard work over a boiling pot, but also practiced skill to keep the threads unbroken. Second, soften the silk gum holding the cocoon’s filaments together by alternating hot and cold immersions. Piles of cocoons are kept under the sun, boiled or exposed to steam. Silk yarns must be washed and degummed by immersing the skeins in large tubs of hot water. upendrachaudhary777 upendrachaudhary777 7 days ago Science Secondary School +5 pts.

Step 2: Thread extraction: Step 3: Dyeing. The process of silk production is known as sericulture. The cruel process of making silk Silk is the fibre that silkworms weave to make their cocoons – outer casings that protect them during the pupal stage. When silkworms are ready to spin, they are inserted into a specially woven circular bamboo scaffolding, which will make the cocoons more uniform in shape and easier to collect.

As the filament of the cocoon is too fine for commercial use, three to ten strands are usually reeled at a time to produce the desired diameter of raw silk which is known as "reeled silk". Step 3: Dyeing. Silk is sometimes—in a process called weighting—treated with a finishing substance, such as metallic salts, to increase weight, add density, and improve draping quality. Silkworms are actually domesticated insects, incapable of flight, mate quickly after emerging from their chrysalis, and die a day or so after laying eggs.
