METHOD FOR PRODUCING SHEET MADE OF ULTRAFINE FIBER

摘要

PROBLEM TO BE SOLVED: To provide a new method for the production of a thin sheet made of ultrafine fibers and having large fabric weight and excellent formation. SOLUTION: The method for the production of a sheet comprises the pressing of a formed material made of fibers having a number-average diameter of 1-500 nm. The invention further provides a method for producing a sheet containing fibers three-dimensionally dispersed in the formed article to form fine pores and voids. COPYRIGHT: (C)2007,JPO&INPIT
