Question

how do you identify the nylon and acrylic fibres​

Answer 1

Answer:

Nylon will give off a white smoke that has a strong, almost celery-like smell. When the flame is removed from burning nylon, it will typically leave a hard yellowish, gray bead. For more information, here is a great video that gives you more information about these and other fibers, and shows how they burn.

Answer 2

Answer:

Acrylic fibers are synthetic fibers made from a polymer (polyacrylonitrile) with an average molecular weight of -100,000, about 1900 monomer units.

Nylon is a generic designation for a family of synthetic polymers, based on aliphatic or semi-aromatic polyamides. Nylon is a thermoplastic silky material that can be melt-processed into fibers, films, or shapes. It is made of repeating units linked by amide links similar to the peptide bonds in proteins.
