PROCESS FOR MAKING NONWOVEN FABRICS BY BONDING ORGANIC FIBERS

摘要

A nonwoven fabric is prepared by simultaneously heating and compressing a nonwoven web of organic fibers which contains a bonding quantity of water as defined in the description. Compressive force and temperature and time of web exposure thereto are correlated to provide a wash stable fabric, but the correlation is such that wash stable bonding of an otherwise dry web is not obtained. A "dry" web is one containing equilibrium water content at 65% relative humidity at 22 DEG C.
