Those who are looking for an answer to the question «Which natural polymer comes from a cocoon rubber wool silk made?» often ask the following questions:

💄 Which natural polymer comes from a cocoon rubber wool silk?

Plastic is not a natural polymer. It is produced by the process of vulcanization that comes under irreversible process/ the springy and soft rubber molecules are locked together that results in the hardening of material with chemical resistance and durability.

💄 Which natural polymer comes from a cocoon rubber wool silk material?

The process of reeling silk from whole cocoons generates waste and the one kilo of cocoons makes only 160 to 200 grams of raw silk (silk which still has sericin). The sericin is about one third of the weight of the raw silk, and after you degum the silk to remove the sericin, you are left with between 100 and 130 grams of silk.

💄 Which natural polymer comes from a cocoon rubber wool silk shirt?

The cocoon is made of raw silk thread of about 1,000-3,000 feet long and 0.0004 inches in diameter. It requires about 3,000 cocoons to produce one pound of silk. Because the process of extracting silk from the cocoon involves the killing of the larva, sericulture has attracted criticism from animal rights activists.

⚫NATURAL POLYMER ️Polymers found in nature are known as natural polymers. ️They are formed by plants and animals. ⚫SYNTHETIC POLYMER ️Polymers made by human beings are known as synthetic polymers. ⏩Among the all option plastic is not a natural polymer because Cellulose, Rubber and Silk are found in nature whereas Plastic is not.

Some of the examples of natural polymers are proteins and nucleic acid that occur in human body, cellulose, natural rubber, silk, and wool. Starch is a natural polymer that is made up of hundreds of glucose molecules, similarly natural rubber is a polymer obtained from the latex of a rubber tree. Polymer products such as synthetic plastics, fibers, rubbers, coatings, adhesives have been applied more and more broadly, and become an group of indispensable material in modern life. Basic human ...

Natural Rubber. Rubber, also known as latex, is an elastomer, a polymer that is prominently known for its elastic properties. Natural rubber is primarily harvested in the form of the latex from the rubber tree (Hevea brasiliensis).

Silk is a natural protein secreted by the larvae of several moth species. The larvae use the filaments to construct a cocoon, from which the silk is extracted. Twin filaments of the protein fibroin are secreted and bound together in a single strand with the protein gum sericin. During processing, the sericin is removed, leaving the fibroin protein.

Silk filament comes from the cocoons built by “silk worms,” which are not worms at all, but silk moth pupae. Silk is used as reinforcement with many kinds of polymers to form the composites that possess good mechanical and thermal properties.

The cocoon is made of raw silk thread of about 1,000-3,000 feet long and 0.0004 inches in diameter. It requires about 3,000 cocoons to produce one pound of silk. Because the process of extracting silk from the cocoon involves the killing of the larva, sericulture has attracted criticism from animal rights activists.

The mulberry silk worm produces large amounts of silk in a convenient cocoon shape that is easily industrialized unlike other natural threads. The natural process of protein organization with such chemical control has not been able to be replicated artificially in a laboratory. The first disadvantages of silk are bound by the limitations of nature.
