Which of the following is generally not drawn into fiber ?
Correct answer: B. Unsaturated polyesters
- A. Polyamide
- B. Unsaturated polyesters
- C. Saturated polyesters
- D. Polyacrylonitrile
Explanation
Unsaturated polyesters generally form cross-linked thermosetting networks, so they cannot be readily softened and drawn into fibres. Polyamides, saturated polyesters and polyacrylonitrile are common fibre-forming polymers.
