ABSTRACT:
There is provided a method of softening a nonwoven web by wetting a nonwoven web having a starting, unstretched width and a starting cup crush value, with an aqueous solution of softening chemicals, necking the saturated nonwoven web, drying the nonwoven web at a temperature and time sufficient to remove at least 95 percent of the moisture from the nonwoven web, wherein the web has a final cup crush value which is less than 50 percent of the starting cup crush value. The method may optionally include the step of un-necking the nonwoven web to about between 80 and 125 percent of its starting, unstretched width.
