Question

Karan had a few fibres with him; he couldn’t not identify which one was silk, wool or nylon. Can you suggest some measures to find out which one is silk, wool or nylon?

Answer 1

Answer:

this is how we can identify silk and wool

Explanation:

For identify slik - we wil a few threads from the material and burn it with a flame. Genuine silk burns with smell of burnt hair. When you burn the edge of real silk fabric, the flame is invisible and it will stop burning as soon as the flame is removed. The ash produced hence, is black, crispy and brittle.

For identify wool- Fill your glass bowl with some water.

Light your match.

Hold fabric over bowl and touch with the lit match. An original wool fabric will immediately catch fire and maintain a steady burn, though it might be difficult to keep it burning. Burnt wool fabrics have the smell of burning hair.
