Method for Making a Shaped Nonwoven
A method for making nonwoven fabric. The nonwoven fabric can include three-dimensional features that define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property. The nonwoven further has a plurality of apertures, wherein at least a portion of the aperture abuts at least one of the first region and the second region of the microzone.
Shaped nonwoven
A nonwoven fabric. The nonwoven fabric can include a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surface. Each of the three-dimensional features can define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property. The nonwoven further has a plurality of apertures, wherein at least a portion of the aperture abuts at least one of the first region and the second region of the microzone.
METHODS FOR PRODUCING THROUGH-FLUID BONDED NONWOVEN WEBS
A method of creating a soft and lofty continuous fiber nonwoven web is provided. The method includes providing first and second, different molten polymers to a spinneret defining a plurality of orifices and flowing a fluid intermediate the spinneret and a moving porous member. The method includes using the fluid to draw the first and second molten polymers, in a direction toward the porous member, through at least some of the plurality of orifices to form a plurality of individual continuous fiber strands. The method includes depositing the continuous fiber strands onto the porous member at a first location to produce an intermediate continuous fiber nonwoven web, and varying, in at least two different zones, a vacuum force applied to the moving porous member and to the intermediate web downstream of the first location and without any heat applied.

Method for Making a Shaped Nonwoven
A nonwoven fabric comprises a first surface, a second surface, and a visually discernible pattern on at least one of the first and second surfaces. The visually discernible pattern has a regular, repeating pattern of three-dimensional features. Each of the three-dimensional features define a microzone comprising a first region and a second region. The first and second regions having a difference in values for an intensive property. The first surface has a TS7 value in the range of about 1 dB V.sup.2 rms to about 15 dB V.sup.2 rms. The second surface has a TS7 value in the range of about 1 dB V.sup.2 rms to about 15 dB V.sup.2 rms. A ratio of the TS7 value of the first surface to the TS7 value of the second surface is in the range of about 1 to about 3.
Delamination-resistant bulky needle-punched structures
Stabilizing a textile sheet structure was achieved by forming a plurality of discrete fiber tufts extending from a first face of a fibrous layer of the textile sheet structure, through the fibrous layer and beyond a second face opposite the first face. Each discrete fiber tuft included a plurality discrete fibers. Each discrete fiber tuft was anchored to the first face and the second face of the fibrous layer by joining together the plurality of each discrete fiber tuft at the first face and the second face and bonding the joined plurality of discrete fiber tuft to the first face and the second face.
