摘　　要：亚麻粗纱优化煮漂工艺如下:(1)在100℃时,用3.5g/lNaOH碱煮30分钟;(2)在80℃时,在pH值为4.5,经30分钟完成亚漂;(3)在90℃时,pH为9的条件下处理20分钟完成氧漂;经煮漂的纱其纤维素含量提高了10.38%,果胶质、木质素、脂蜡等含量下降到了较好的水平,白度达到69.68%,大幅度改善了亚麻的纺织性能和服用性能。A process for kiering and bleaching flax roving was presented： （1） Flax roving was kiered with 3.5g/1 NaOH at 100℃ for 30 minutes; （2） prime bleaching with chlorite at 80℃ ,pH 4.5 for 30 minutes; （3） then bleaching with peroxide at 90℃, pH 9 for 20 minutes. After kiering and bleaching, the content of cellulose was increased by 10.38%, the contents of pectin, lignin, wax etc. dropped to a satisfied level, whiteness achieved 69.68%, the spinning performance and wearability were greatly improved.
