DYES FOR VINYL FIBERS

The  vinyl  fibers, with   the  exception  of  vinal  and  vinyon-vinal  matrix fibers, are  extremely  hydrophobic and difficult  to  dye,  and   consequently they  can  be dyed  only  through  pigmentation  of  the  polymer  melt   before fiber formation  or  through  dyeing  with  disperse dyes. Vinal  and  vinyon-vinal matrix   fibers  dye  readily  with dyes   used  on  cellulosics  including direct, mordant, reactive, vat,  and  sulfur dyes.
