    • Individual glass fibers are coated with a composition which includes the condensation product of a polycarboxylic acid or anhydride and a polyfunctional amine. The preferred coating composition comprises an aqueous mixture including the aforementioned condensation product and an elastomeric styrene-butadiene-vinylpyridine terpolymer latex. An aqueous solution of the coating composition is prepared and applied to glass fibers as a sizing composition and/or as a coating composition after the glass fibers are sized. Subsequent to coating the glass fiber strands with the aforementioned coating composition, the strands are dried by heating in a microwave oven, a forced air oven or the like.
    • 单独的玻璃纤维涂覆有包含多元羧酸或酸酐与多官能胺的缩合产物的组合物。 优选的涂料组合物包括含有上述缩合产物和弹性体苯乙烯 - 丁二烯 - 乙烯基吡啶三元共聚物胶乳的水性混合物。 制备涂料组合物的水溶液并施加到作为上胶组合物的玻璃纤维和/或玻璃纤维尺寸后作为涂料组合物。 在用上述涂料组合物涂布玻璃纤维束之后,通过在微波炉,强制空气烘箱等中加热干燥线。
