A method for manufacturing
polyvinyl alcohol fibers, comprising the steps of: providing a
polyvinyl alcohol composition comprising: a homo-
polyvinyl alcohol having a degree of
hydrolysis of 88% to 98% or more and a weight average molecular weight of 14,000 to 22,000; a
plasticizer selected from the group consisting of diglycerol, triglycerol,
fructose,
ribose,
xylose, D-
mannitol,
triacetin,
pentaerythritol, dipentaerythritol, methyl pentanediol, 1, 2-
propanediol, 1, 4-
butanediol, 2-hydroxy-1, 3-
propanediol, 3-methyl-1, 3-
butanediol, 3, 3-dimethyl-1, 3-
butanediol, 1, 3-butanediol, 3, 3-dimethyl-1, 3-butanediol, 3, 3-dimethyl-1, 3-butanediol, 3, 3-dimethyl-1, 3-butanediol, 3, 3-dimethyl-1, 3-butanediol, 3, 3-dimethyl-1, 3-butanediol, 3, 3-dimethyl-1, 3-butanediol, 3, 3-dimethyl-1, 3-butanediol, 3, 3-dimethyl-1, 3-butanediol, 3 the component A is prepared from 1, 2-butanediol,
polyethylene glycol 300,
polyethylene glycol 400, alkoxylated
polyethylene glycol,
caprolactam,
tricyclic trimethylolpropane methylal, abietate,
erucyl amide and a mixture of 1, 2-butanediol,
polyethylene glycol 300,
polyethylene glycol 400, alkoxylated
polyethylene glycol and
caprolactam; and an optional stabilizer selected from the group consisting of
sodium stearate,
potassium oleate,
sodium benzoate,
calcium stearate,
stearic acid, dimethyl, propionic acid, and mixtures thereof; melting the composition at a temperature of 200 DEG C to 230 DEG C to form a molten
polymer; extruding the molten composition to form an extrudate; forming the extrudate into molten fibers; and solidifying the molten fibers to form
solid fibers.
