化学过滤器及其制造方法
摘要：
本发明提供一种能够长期维持离子性气态污染物质的除去性能的化学过滤器。该化学过滤器是对无纺布进行褶皱加工而得到的化学过滤器，其特征在于，该无纺布是通过水刺法使纤维交错而制成的水刺无纺布，在该纤维中通过辐射接枝聚合导入有离子交换基。
摘要（英）：

The invention provides a chemical filter capable of maintaining removal performance of ionic gaseous pollutants for a long time. The chemical filter is obtained by pleating a nonwoven fabric, the nonwoven fabric being a spunlace nonwoven fabric prepared by causing fibers to be entangled by a spunlace method, and ion-exchange groups being introduced into the fibers by radiation graft polymerization.
