The plurality of apertures include a first set of apertures defining a first shape and a second set of apertures defining a second shape.
METHODS FOR MAKING PATTERNED APERTURED WEBS
A method of producing a patterned apertured web is provided. The method comprises providing a web having a central longitudinal axis. The web comprises a plurality of overbonds extending substantially parallel to the central longitudinal axis. The method comprises conveying the web in a machine direction that is substantially parallel to a direction of extension of the central longitudinal axis of the web. The method comprises stretching the web in a cross-machine direction to cause at least some of the overbonds to at least partially rupture and at least partially form patterned apertures in the web. At least some of the patterned apertures have Absolute Feret Angles, according to the Aperture Test herein, of at least about 20 degrees. At least some of the patterned apertures have an Aspect Ratio, according to the Aperture Test herein, in the range of about 2:1 to about 6:1.
PRE-STRAINED LAMINATES AND METHODS FOR MAKING THE SAME
A laminate comprising a first nonwoven layer comprising a plurality of apertures and a second nonwoven layer is provided. One of the first and second nonwoven layers is a pre-strained layer and is joined to the other one of the first and second nonwoven layers. The other one of the first and second nonwoven layers is a non-pre-strained layer. The pre-strained layer and the non-pre-strained layer together form a three-dimensional laminate.
SANITARY NAPKIN FOR CLEAN BODY BENEFIT
