Question

why are acrylic not spun from melt ​

Answer 1

Answer:

All commercial acrylic fibers are prepared using wet or dry spinning methods. Melt spinning cannot be applied because the acrylic polymers degrade upon heating. Polymers are dissolved in the appropriate solvent to form a spinning dope.

Answer 2

• Acrylics are so named because they are made from polymer polyacrylonitrile. 

• They are not spun from the melt because these polymers decompose without melting. 

• Thus, they are dissolved in a specific solvent and the solution is forced through spinnerets to obtain filaments that are spun into yarns.
