and
synthetic She does not know which one
is natural fiber and which is synthetic fiben
which activity you will suggest to identify
the fibers ?​

Answer 1

Answer:

Distinguish between artificial silk and natural silk.

1. Take a piece of natural silk fabric and another piece of artificial silk fabric.

2. Burn both the fabrics separately and observe the smell produced.

Conclusion:

1. The fabric which burns giving a smell of burning hair will be natural silk or pure silk.

2. The fabric which burns giving a smell of burning paper will be artificial silk.

Just like silk, wool is also made up of proteins. So, a piece of woollen fabric also burns giving the smell of burning hair.

Hence, Neha Bhabi can use this method to identify which is natural fiber from synthetic fiber.

Hope it helps you!
