    • A method of sizing a hydrophobic yarn for weaving comprising the steps of applying thereto an acid pH latex of a free radical initiated vinyl polymer and drying the yarn. The polymer has a weight average molecular weight of from about 300,000 to about 2,500,000, and in dried film form is hydrophobic, not redispersible in a solution at a low pH and redispersible in an alkaline aqueous medium. The polymer is prepared from monomers comprising about 8% to about 14%, by weight ethylenically unsaturated acid. The average solubility parameter of the monomers in the polymer is between about 9.0 and about 9.5; the calculated polymer T.sub.g is between about -20.degree. C. and 20.degree. C. Preferred yarns are nylon and polyester.
    • 一种用于编织的疏水性纱线的施胶方法,包括以下步骤:向其施加自由基引发的乙烯基聚合物的酸性pH胶乳并干燥纱线。 聚合物的重均分子量为约300,000至约2,500,000,干燥形式为疏水性,不可再分散于低pH下的溶液中,可再分散于碱性水性介质中。 聚合物由包含约8%至约14%(重量)烯属不饱和酸的单体制备。 聚合物中单体的平均溶解度参数为约9.0至约9.5; 计算的聚合物Tg在约-20℃和20℃之间。优选的纱线是尼龙和聚酯。
