Problems solved by technology
Therefore, there is a problem that the density of the nonwoven web and fibers increases (but the bulkiness becomes smaller) around the perforations
In addition, there are problems of damage to fibers and increase of surge layer hardness due to physical pressure or thermal pressure applied in the perforating step

Abstract
The present invention provides a method of manufacturing a nonwoven web perforated without physical or thermal deformation and an absorbent article including such a nonwoven web. The absorbent article of the present invention comprises the following: a liquid-permeable top sheet; a liquid-impermeable back sheet; an absorbent body disposed between the top sheet and the back sheet for absorbing a liquid permeating through the top sheet; and a surge layer disposed between the top sheet and the absorbent body for delivering the liquid permeating through the top sheet to the absorbent body. The surge layer includes a nonwoven web perforated without physical or thermal deformation.
Description
technical field [0001] The present invention relates to methods of making perforated nonwoven webs free from physical or thermal deformation and absorbent articles containing such nonwoven webs. More particularly, the present invention relates to absorbent articles, such as diapers, sanitary napkins, liners, etc., which contain perforated nonwoven webs that are free from physical or thermal deformation while retaining moisture from the body of the user. Large volumes of liquid are quickly collected and smoothly conveyed to the absorbent body. Background technique [0002] figure 1 An example of a conventional absorbent article is shown. see figure 1 , a conventional absorbent article 10 comprising: a liquid-permeable topsheet 2 on the body side; a liquid-impermeable backsheet 4 on the outside; an absorbent body 6 disposed between the topsheet 2 and the backsheet 4; Surge layer 8 between topsheet 2 and absorbent body 6 . [0003] The topsheet 2 is capable of contacting t...
