초록 ▼

Warp sizing compositions are used to treat textile yarn to withstand the abrasive forces encountered by the warp yarn during weaving. A warp sizing composition having poly(vinyl alcohol); and a second film forming polymer, which is water soluble, dispersible or emulsifiable and having a Tg of less than 70°C., and an average particle size of less than 5 microns, and being dispersible with poly(vinyl alcohol); and water results in treated yarn having good flexibility, and abrasion resistance strength. The more flexible treated warp yarn encounters less damage during the slashing operation to result in improved weaving performance. The process for producing glass fiber strand yarn treated with the warp sizing composition involves forming the glass fibers, treating the glass fibers with a forming size, gathering the glass fibers into one or more strands, collecting the strands, drying the strands to remove enough moisture to enable the strands to be removed from the collected strand package, rewinding the strands, beaming a plurality of the rewound strands, treating the plurality of rewound strands from a beam with the warp sizing composition, drying the treated strands, splitting the dried treated strands and winding the split strands onto a beam.

A textile yarn warp sizing composition, comprising: a. a major amount of the solids of the composition of one or more water soluble, emulsifiable or dispersible fiber forming poly(vinyl alcohol) polymers, b. an amount of about 1 to about 50 weight percent of the solids of the composition of a water soluble, emulsifiable or dispersible second film forming polymer dispersible with the poly(vinyl alcohol) having a Tg of less than 70°C. and present in a particle size of less than 5 microns, and c. water in an amount to give a solids content to the composition in the range of about 3 to 25 weight percent.
