Why is a cocoon that produces a live silk moth usless for making silk cloth?

If the moth hatches, it chews its way out of the cocoon, cutting all the silk fibers. for silk production, the caterpillar is killed before it hatches, so the silk strands can be unwound and remain whole.

What is the source of silk threads?

Silkworms, a type of caterpillar, are the source of silk threads. Silkworms make a cocoon about an inch long in an oval shape. Silkworms only eat the leaves of white mulberry trees.

Where does silk come from what happens to the cocoon?

Silk comes from the cocoon spun by the silk work. The cocoon is unwound and the silk is then processed for use by humans.

How is silk obtained and manufactured?

We obtain silk by killing the larvae inside by a process called stiffling by putting a lot of these in a steam even for 10 to 15 minutes. Obtaining silk fibre from cocoon is called reeling. It is done with special machines called reelers and twisters. The silk fibre is carefully collected from the cocoon and nearly 3 to 8 of such threads are wounded together to make yarn from it which is reeled. This yarn is cleaned, bleached and colored. This yarn is ready.

Is silk is a polymer?

Silk is natural, not a man-made polymer. The silk is mainly obtained from the cocoons of the Mulberry Silkworm (Bombyx mori). When the caterpillar forms a pupae, it encases itself in a cocoon of fine silk thread. Before the adult moth emerges, the cocoon is steeped in hot water to kill the developing moth inside. The cocoon is then unravelled and is combined with several other silk threads to produce a strong silk thread that can be used to produce silk fabric.

What is a silk-moth home called?

You could call it a cocoon.

Why are silk cocoons boiled?

Silkworm cocoons are placed in boiling water to make the one long continuous thread separate from it.

How fibers are obtained?

Silk fibers are obtained from the cocoon of silk larvae, larvae of the silk moth, which are spun from the cocoon into one, long thread.

How is silk made into fabrics?

Production of Silk from Cocoon to FactorySericulture: The production of cocoon for their filament is called sericulture. The species Bombyx mori is usually cultivated and is raised under controlled condition of environment and nutrition. The life cycle of silk worm encircle in the four stages. The egg, the silk worm, the pupa and the moth. The silk worm which feeds on mulberry leaves forms a covering around it by secreting a protein like substance through its head. This stage is called cocoon, the desirable stage for the silk producers.Filature operations: The cocoons raised by the farmer are delivered to the factory, called a filature, where the silk is unwound from the cocoons and the strands are collected into skeins. Some cocoons are scientifically bred in such factories. The filature operations consist of the following stages.a) Sorting cocoons :The cocoons are sorted according to the color, size, shape and texture as these affect the final quality of the silk. Cocoons may range from white and yellow to grayish.b) Softening the Sericin : Silk filament is a double strand of fibroin, which is held together by a gummy substance called sericin or silk gum. After the cocoon has been sorted, they are put through a series of hot and cold immersions, as the sericin must be softened to permit the unwinding of the filament as one continuous thread.c) Reeling the filament : Reeling is the process of unwinding the silk filaments from the cocoon and combining them together to make a thread of raw silk. 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". The useable length of reeled filament is 300 to 600 m.d) Bailing : The silk filament is reeled into skeins, which are packed in a small bundles called books, weighting 2 to 4.5 kg. These books are put into bales weighing about 60 kg. In this form raw silk is shipped to silk mills all over the world.

Why was spinning wheel important to Chinese?

Silk was first made by the Chinese about 4000 years ago from the cocoon of the silkworm moth. Silk spinners needed a method to deal with the tough, long silk threads. This is why the spinning wheel was so important in China.
