ZONED AND/OR LAYERED SUBSTRATES AND METHOD AND APPARATUS FOR PRODUCING THE SAME
Methods and apparatuses for producing a zoned and/or layered substrate are described. A substrate can include a first layer including a first zone, a second zone, and an interface between zones. The first zone can include a plurality of fibers. The second zone can include a plurality of fibers and can be offset from the first zone in a cross-direction. The interface can include at least some of the plurality of fibers of the first zone and at least some of the plurality of fibers of the second zone to provide a purity gradient with a transition width less than 3.8 cm as defined by the Purity Gradient Test Method as described herein.
Method for preparing a nonwoven web
The present invention relates to a method for producing a nonwoven fabric. The method according to the invention comprises forming a nonwoven web using a wet lay forming process, hydroentangling the web and providing the web with a high quality hydroembossed pattern. The invention also concerns a nonwoven fabric exhibiting a three dimensional pattern, which remains even in wet wipes prepared from the material.
NONWOVEN WEB WITH INCREASED CD STRENGTH
The present invention discloses a nonwoven web and methods for manufacturing the nonwoven web. One aspect of the invention includes a plurality of outwardly facing nozzles that are positioned at various angles with respect to the axis of a pipe the nozzles are located on. Another aspect of the invention pertains to perturbing at least a portion of a fiber matrix prior to the fiber matrix collecting on a forming surface. The perturbed fiber matrix provides for an increase in cross-machine direction fiber strength of the nonwoven web.

SOFT AND STRONG TISSUE PRODUCT INCLUDING REGENERATED CELLULOSE FIBERS
The present invention provides a wet-laid tissue product comprising regenerated cellulose fibers that can provide 25% or less of the total weight of the wet-laid tissue product. The regenerated cellulose fibers can have a denier of less than 0.9 and a fiber length of less than 6.0 mm. The wet-laid tissue product can provide improvements in softness at a given strength.
Multi-ply dispersible nonwoven fabric
The invention relates to a nonwoven fabric material having sufficient strength to be used in a pre-moistened state but also having dispersibility properties which allow the product to be flushed. The material comprises at least two nonwoven webs, at least one of which is hydroentangled. Each of the individual webs comprise 50%-95% wood pulp and 5%-50% of short cut man-made fibers and/or natural fibers and has a basis weight of 20-100 gsm. After forming the webs, the two nonwoven webs are dried and then joined together by particle binders through size press or spraying. The particle binder joined webs separate into individual webs after flushing due to the breakage of particle binder-nonwoven hydrogen bond which makes the material highly dispersible.

Compacted Fibrous Structure Articles and Methods for Making Same
Compacted fibrous structure articles and methods for making the same are provided.
Absorbent hygienic article for absorbing body fluids
An absorbent hygienic article for absorbing body fluids, the article including a liquid permeable topsheet, a backing layer and an absorbent core arranged between the topsheet and the backing layer, the topsheet and the backing layer being made from roll materials. The topsheet or an absorbent layer in the absorbent core is constituted by a cellulosic fibrous web, the fibres in the cellulosic fibrous web being constituted by a mixture of cellulose fibres including regenerated cellulose fibres or natural cellulose staple fibres and cellulose pulp fibres, the cellulosic fibrous web being a foam-formed, hydroentangled fibrous web.
LAMINATE FOR USE IN AN ABSORBENT ARTICLE
A laminate including a substrate layer and a fibrous layer. The fibrous layer includes cellulose fibers and irregularly shaped lumps of a hotmelt material. The lumps of hotmelt material may at least partially bond the cellulose fibers together, thus increasing the integrity and resilience of the fibrous layer.
