In case of wet spinning of polymers, the polymer solution is forced through spinnerates into, a coagulating bath to give a filament form. Wet spinning is not used in case of the _____________ fibres?
Correct answer: B. Saturated polyester
- A. Viscose rayon
- B. Saturated polyester
- C. Polyvinyl acetate
- D. Acrylic
Explanation
Viscose rayon, acrylic polymers and some polyvinyl acetate fibres can be produced by wet spinning through a coagulation bath. Saturated polyesters are commonly melt-spun because they can be melted and extruded directly.
