POROUS COMPOSITE SHEET AND PROCESS FOR THE PRODUCTION THEREOF

摘要

A sintered porous composite sheet, comprising an A/B-component layer in whic h A-component having easily fusible properties and B-component having relatively higher thermal stability as compared with A-component coexist in a sintered state. A-component can comprise a hydrophilic material, B-component can comprise a hyd rophobic material, and A-component and B-component can contain a common mater ial comprising an easily fusible material. The porous composite sheet has advantag es that it has moderate air- or moisture permeability and is excellent in drapabilit y; and is most suitable to a material for sanitary or medical wares.
