Why is silk a costly fiber?​

Answer 1

Answer:

Silk is very expensive because its production is very laborious and land-intensive. It is made up of protein fibres which are triangular and so reflect light like prisms. It takes approximately 650 silkworm cocoons and 100 labour hours to produce sufficient silk fabric to make one blouse.Silkworms spin cocoons that silk producers eventually unravel and join to create the thread. Silk production costs have gone up with the introduction of synthetic fabrics like polyester.Silk is the product of the domesticated silkworm, Bombyx mori. The caterpillars eat constantly.
