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 else can I help you with?
What is the monomer of the polymer silk?
Silk is actually a polymer made by protein complexes in the repeating fashion.
What is silk polymer?
The polymer of protein is protein .
What is a natural polymer created by many caterpillars and spiders?
Silk is a natural polymer produced by many caterpillars to form cocoons and by spiders to create webs. It is made up of proteins and is known for its strength, elasticity, and biodegradability.
How is a silkworm related to a polymer?
A silk worm produces silk, which is made up of proteins and amino acids that form polymers when they are joined together.
Is silk a polyacronitrile?
Since, according to Wikipedia's definition, "Polyacrylonitrile (PAN) is a synthetic, semicrystalline organic polymer resin, with the linear formula (C3H3N)n," and since silk is produced by silk worms, the answer must be no.
Is silk a Synthetic fabric?
Yes, Lycra is a synthetic fabric that was made in 1958 as an alternative to making corsets with rubber. Oftentimes it is blended in with natural fabrics such as cotton or silk. It's made of polymer.
What is the chemical formula for fabric silk?
Silk is primarily composed of proteins, specifically fibroin, which does not have a fixed chemical formula like small molecules. However, the repeating units of fibroin can be represented by the general formula (C15H18N2O6S)n, where "n" denotes the number of repeating units in the polymer chain. Silk's structure also includes sericin, another protein that contributes to its properties. Overall, silk is a complex natural polymer rather than a single chemical compound.
What is a tent made from a polymer developed in a chemical laboratory silk wool cotton or nylon?
A tent made from nylon is the most likely to be constructed using a polymer developed in a chemical laboratory. Nylon is a synthetic polymer that is commonly used in outdoor gear like tents due to its durability, water-resistant properties, and lightweight nature.
A natural polymer in some clothes?
Silk would conform to this need. usually the silk from the silkworm. But some challenging items have been woven from spider silk. [In Madaskar a cloth measuring 11' by 4' was woven by 82 people over a period of 4 years, and used the silk from over a million Golden Orb web spiders. Spiders have been taken into space (a student project!) and successfully wove webs. ]
What is polymer of silk?
The polymer is 'proteine' or better 'polypeptide' (n= big number) and monomer is a 'tetrapeptide' existing of 4 (=tetra) amino acids: -[Gly-Ser-Gly-Ala]n- (lineary coupled, n-times, in this order).(Note the alternating sequence of glycene (Gly) with serine (Ser) and alanine (Ala))The high proportion (50%) of glycine (GLY), which is the smallest amino acid (H2N-CH2COOH), allows tight packing, so the fibers are strong and resistant to stretching. The tensile strength is due to the many interseeded hydrogen bonds.Since the protein forms a 'Beta plated sheet', when stretched the force is applied to these strong bonds and they do not break.
What polymer was invented fifty years ago to replace silk?
Nylon, invented by a chemist at the DuPont Chemical Company in 1935, and first used in women's stockings in 1940.
Are polymers are all synthetic?
