    • A process including shearing a first dispersion medium and a second dispersion medium under conditions that precipitate a plurality of polymeric fibers; and collecting the plurality of polymeric fibers at a rate of at least 300 grams/hour. The first dispersion medium is a solution including at least one polymeric component. The at least one polymeric component includes a poly-etherimide component selected from the group consisting of polyetherimide homopolymers, polyetherimide co-polymers, poly etherether ketones homopolymers, polyetherether ketones copolymers, polyphenylene sulfones homopolymers, polyphenylene sulfones copolymers, and combinations thereof. Products produced by the process can be non-woven paper, medical implants, ultra-fine filters, membranes, hospital gowns, electrical insulation paper, honeycomb structures and personal hygiene products, dialyzers, blood, oxygenator filters, intravenous (IV) filters, diagnostic test filters, and blood/apheresis filters.
    • 包括在使多种聚合物纤维沉淀的条件下剪切第一分散介质和第二分散介质的方法; 并且以至少300克/小时的速率收集多根聚合物纤维。 第一分散介质是包含至少一种聚合物组分的溶液。 所述至少一种聚合物组分包括选自聚醚酰亚胺均聚物,聚醚酰亚胺共聚物,聚醚醚酮均聚物,聚醚醚酮共聚物,聚亚苯基砜均聚物,聚亚苯基砜共聚物及其组合的聚醚酰亚胺组分。 该过程生产的产品可以是非织造纸,医用植入物,超细过滤器,膜,医院长袍,电绝缘纸,蜂窝结构和个人卫生产品,透析器,血液,充氧器过滤器,静脉注射(IV)过滤器,诊断 测试过滤器和血液/ apheresis过滤器。
