How will you distinguish between natural artificial silk?
Answers
Answer:
Explanation:
Natural silk :- is a natural protein fibre we get from silkworms (Bombyx mori). Silk is produced by these insects larvae to form cocoons. They spew out the thread from tiny holes in their jaws, which they use to spin into their egg-bearing cocoons. This entire production takes a mere 72 hours, during which time they produce between 500-1200 silken threads.
One can find easily by burning a few threads.Silk burns slowly and curls away from the flame. It leaves a dark bead which can be easily crushed. It is self-extinguishing and leaves ash that is a dark, gritty, fine powder. It smells like burned hair or charred meat. It gives out little or no smoke and the fume has no hazard.
Artificial Silk :- is usually a term used for Rayon which imitates the feel and appearance of natural silk but actually, it is a manmade fibre, Produced synthetically with natural cellulose of wood pulp with chemicals like carbon disulfide.
Artificial silk i.e. Rayon burns without flame or melting and may flare up. Unless there is a fabric finish, it doesn't leave any bead. After the flame is removed, it may glow a bit longer than cotton. It smells like burning paper and leaves soft, gray ash. Its smoke is a little hazardous.
