Q. Silkworms secrete fibre made of (a) fat (b) cellulose (c) protein (d) nylon
- c) Protein
It is well established that silkworms generate silk, which is collected first from the cocoons of the larvae of the silkworm.
These caterpillar/silkworm cells secrete a protein-based fibre that hardens when exposed to the air and then becomes silky fibre. Silkworms entirely wrap themselves in silk strands, forming a cocoon, which will then be treated to extract silky fibres. The following processes must be performed for silk to be produced by silkworms:
The following processes must be performed for silk to be secreted by silkworms:
Stage 1: Cocoons are gathered and stored beneath the sun in this phase. Alternatively, it can be cooked or subjected to steam. This aids in the separation of silk fabrics in cocoons. Reeling the silk refers to the process of separating the fibre surface first from the cocoon.
Stage 2: The silk fibre acquired out of a cocoon is spun into silk thread in this step.
Stage 3: Finally, the silk strands are weaved into the required garments in this step.
Silkworms make silk, as we all know. Silk is indeed a protein-rich fibre that may be used to weave textiles. In addition, fibroin is indeed a protein fibre that is generated by silkworm larvae to build cocoons which are used to make silk.
When exposed to the environment, the protein fibre released by silkworms hardens into silk fibre. The silkworm is coated with silk fibre, which forms a cocoon, which will then be applied to generate silk fibre.
The finest silk comes from mulberry silkworm larval cocoons. Sericulture, or silk farming is indeed the practice of commercially cultivating silkworms to produce silk. Bombyx & Mori are the commercial silk subspecies used in sericulture.
