Definitions

  • the present invention relates to a fiber sizing agent. More particularly, the present invention pertains to a fiber sizing agent which is industrially useful because it provides such excellent weavability that tackiness or fixing in sized fiber does not occur even at a high temperature and high humidity and that the coherence is not lost even at a low temperature and low humidity. Sizing textile fibers with the inventive sizing agent imparts them with coherence prior to weaving with a loom.
  • PVA polyvinyl alcohol
  • (meth)acrylic acid ester copolymers and the like as the sizing agent to be applied to the warp of a textile product for the purpose of reinforcement.
  • PVA has been widely used as a fiber sizing agent because it forms tough films, has excellent bundling protecting action for textile fibers, non-putrefactiveness, preservability for a long period of time, and the like in comparison with starch.
  • PVA has water-solubility (a degree of hydrolysis of not less than 88 mol%), it has insufficient adhesivity to hydrophobic fibers at a low temperature and low humidity, thereby frequently causing troubles due to off-sizing or insufficient cohesion power at the time of weaving.
  • the PVA causes the sized fibers to unfavorably have tackiness or fixing due to hygroscopic action when being stored under high humidity in summer.
  • problems in the case of filament yarn as poor rewinding (blocking) from the sized fiber beam (weaver's beam), increase in yarn hairiness, poor shedding property, etc.
  • problems in the case of spun yarn as excessively high coefficient of friction due to tackiness of sized fibers such as yarns, poor shedding property, weft stop, occurrence of hairy pills, etc.
  • the object has been solved by the surprising finding that the properties of PVA having a low degree of hydrolysis which include hygroscopicity, tackiness and fixing can dramatically be improved by the use of a specific composition as a fiber sizing agent for sizing textile fibers, which composition comprises PVA having a specific degree of polymerization as well as a specific degree of hydrolysis and an ammonium salt of a carboxyl group-containing polymer in a definite range of proportion, thus adapting itself to the purpose of a fiber sizing agent.
