    摘要: The present invention relates to a nonwoven web comprising a plurality of loops. At least one of said loops having a loop circumference length to loop base length ratio that is greater than about 4:1. The loops may also have a base length less than 0.5 cm and a base length less than the maximum width of the loops. The present invention also relates to articles selected from the group consisting of disposable hygiene article and wipes comprising a nonwoven web wherein at least one region of the nonwoven web comprises loops in at least about 10% of the surface area of the nonwoven web. A method for producing a nonwoven web comprising a plurality of loops is also included. The method comprises the steps of providing a nonwoven web; providing means for moving fibers of the nonwoven web into the shape of a loop; and moving fibers of the nonwoven web into the shape of a loop.

    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.
