摘　　要：以洋麻和对位芳纶为原料,以5种洋麻/芳纶混纺纱线为研究对象,使用蒸馏水、5%氢氧化钠和5%盐酸分别处理混纺纱线,研究蒸馏水、酸、碱对混纺纱线性能的影响。结果表明:经过蒸馏水及5%酸碱溶液处理后,纱线的线密度都有不同程度的减小,其中酸的影响最大;洋麻/芳纶混纺纱线经过酸碱处理后强度损失率比纯芳纶纱线小;随着洋麻含量的增加,纱线强度的损失率减小。With kenaf and para-aramid as raw materials , five kinds of kenaf/aramid blended yarn , treated with distilled water, 5% sodium hydroxide and 5% hydrochloric acid respectively , were studied.The results show that the fineness of blended yarns is reduced , after treated by distilled water , 5%acid and alkali solution, wherein the acid of the maximum reduction .After acid and alkali treatment , the kenaf/ar-amid blended yarn strength loss rate becomes smaller than that of pure aramid yarn , showing kenaf con-tent increases and the yarn strength loss rate decreases .
