摘　　要：用聚丙烯酸接枝淀粉浆液，在ＰＶＡ 非织造布上形成吸水树脂，从而得到高吸水性非织造布。对接枝单体的比例、交联条件、浸轧量及非织造布规格等因素对高吸水非织造布吸水性能的影响进行了讨论并测定了其生物降解性能。Polyacrylic acid grafted starch was synthesized. Thick liquid of polyacrylic acid grafted starch was coated on PVA nonwoven fiber to get nonwoven with high water absorptivity. In this paper, the effect of ratio of grafting monomer ,cross linking condition, weight of absorbed thick liquid in the nonwoven and the nature of the nonwoven on the absorptivity of the nonwoven were discussed. The biodegradability of PVA nonwoven with high water absorptivity was also determined .
