Abstract (en)
There is disclosed a fiber sizing agent which comprises a polyvinyl alcohol (A) having a degree of hydrolysis of 60 to 99 mol% and a degree of polymerization of 100 to 5000, and an ammonium salt of a carboxyl group-containing polymer (B) in a blending ratio (A) : (B) of 15 : 85 to 99.9 : 1 by weight. The above fiber sizing agent has excellent adhesivity, cohesion power and abrasion resisance irrespective of a low temperature and low humidity or a high temperature and high humidity and also has such excellent weavability as free from the occurrence of off-sizing, tackiness, fixing, gumming-up or the like in the sized fibers.
