Acrylic shrinkable fiber and method for production thereof
TL;DR: In this paper, a method for producing an acrylic dyeable and shrinkable fiber being reduced in the shrink during dying and exhibiting a high shrinkage factor even after dyeing, which comprises spinning incompatible fluid stocks for spinning.
Patent
Acrylic wet spinning process
TL;DR: By adjusting the viscosity of the spinning solution, low molecular weight polymers of acrylonitrile can be spun to provide useful fiber having an unexpected higher dye color yield than fiber prepared from the corresponding polymer of higher molecular weight.
