Abstract

PURPOSE:To obtain a porous sheet having smooth surfaces, excellent fouling and water pressure resistance with superior durability, by providing a porous layer of a polyurethane based polymer having fluorocarbon segments on a substrate. CONSTITUTION:A porous sheet material having a polyurethane based polymer is produced. In the process, water is emulsified in a solution and/or dispersion of a polymer prepared by a covalently bonding fluorocarbon segments to, e.g. the backbone chain and/or side chains, of a polyurethane based polymer obtained by reacting a well-known polyol with a polyisocyanate and a chain extender so as to account for 0.2-50wt.% in the total amount of the above-mentioned polyurethane based polymer in an organic solvent. A fiber substrate is then impregnated and/or coated with the resultant water-in-oil type emulsion of the aforementioned polyurethane polymer and gelatinized to afford a sheet material having a porous layer formed thereon. This sheet material has smooth surfaces, excellent fouling and washing resistance and good feeling in spite of porosity thereof.
