Fremgangsmåde til fremstilling af nonwovenstoffer

摘要

A method of forming apertured webs is provided comprising the steps of: (a) forming a foraminous member comprising gross foramina and fine foramina wherein the gross foramina define a patterned design superimposed on the fine foramina by means of applying and curing a photosensitive resin onto a foraminous element comprising fine foramina in order to form elevated portions on the fine foramina defining the gross foramina, (b) providing a layer of fibers on said foraminous member; and (c) applying fluid streams to said layer of fibers such that the fibers are randomly entangled in regions interconnected by fibers extending between adjacent entangled regions in a pattern determined by the pattern of the gross foramina of the foraminous member to form an apertured web.
