A fire-proof plastic - Melamine.
Artificial wool is prepared from another type of synthetic fibre called acrylic. The wool obtained from natural sources is quite expensive.
a nylon thread is stronger than a steel wire, also nylon fibre is strong, elastic and light.
Such a fibre was obtained by chemical treatment of wood pulp. This fibre was called rayon or artificial silk.
