HYDROPHILIC ULTRAHIGH-MOLECULAR-WEIGHT PLASTIC POROUS SHEET AND METHOD FOR MANUFACTURING SAME

摘要

The purpose of the present invention is to provide a hydrophilic porous sheet having high water absorbency. The purpose of the present invention is furthermore to provide a hydrophilic porous sheet having excellent adhesive strength as well. The purpose of the present invention is also to provide a simple method for manufacturing the porous sheet. The present invention relates to a hydrophilic ultrahigh-molecular-weight plastic porous sheet characterized by being configured from an ultrahigh-molecular-weight plastic having an absorption rate of at least 15 mm/3 minutes when one end of a sheet thereof is dipped in pure water in an atmosphere at 25°C and 60% RH, a characteristic absorption being observed at 3000-3500 cm-1 in the IR spectrum thereof measured by infrared spectroscopy (FT-IR).
