Polymer Technology

Melt spinning of polymers involves the forcing of polymer melt through spinnerates (fine holes) into an atmosphere kept at a temperature lower than the melting point of the polymer, which causes the fine diameter polymer melt to harden into filaments. Melt spinning is not used in case of the _____________ fibres?

Melt sning of polymers involves the forcing of polymer melt through snerates (fine holes) into an atmosphere kept at a temperature lower than the melting point of the polymer, which causes the fine diameter polymer melt to harden into filaments.

A. Acrylic
B. Polyester
C. Nylon 6:6
D. Polypropylene
