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?
Correct answer: A. Acrylic
- A. Acrylic
- B. Polyester
- C. Nylon 6:6
- D. Polypropylene
Explanation
Acrylic fibres are generally produced by dry or wet spinning because common acrylic polymers do not melt-process cleanly before degradation. Nylon, polyester, and polypropylene can be formed by melt spinning.
