An installation and a method for selectively producing a single-ply or alternatively a multi-ply nonwoven includes an inclined wire former configured to deposit a sheet of wet-laid fibre material on a first circulating belt, a further belt configured to receive the sheet of wet-laid fibre material from the first circulating belt, a roller card arranged downstream in the material transport direction and configured to introduce a roller card web into the installation, a hydroentanglement arranged downstream in the material transport direction and including at least one water beam configured to entangle, bond and/or structure a single sheet of fibres or a plurality of sheets of fibres, and a dryer arranged downstream in the material transport direction

A non-woven sheet (10) comprises at least one zone of reinforcement (20a, 20b, 20c, 20d) in which fibers and/or filaments constituting the sheet are bonded together in a reinforcing pattern (22) comprising a plurality of geometric shapes (24), the zone of reinforcement extending over the entire length (L) of the sheet measured in the longitudinal direction (X1), and over a width (l1, l2) strictly less than the width (l) of the sheet (10) measured in a lateral direction (Y1) orthogonal to the longitudinal direction (X1). The sheet (10) thus further comprises at least one non-reinforced zone (30a, 30b). Because of the bonding between the fibers and/or filaments, the elongation of the reinforced zone (20a, 20b, 20c, 20d) under the effect of a given force exerted in a longitudinal direction of the sheet (10) is less than the elongation of the non-reinforced zone under the effect of the same force. Such a sheet (10) may be used in particular for fabricating a laminated assembly.

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.

Covers comprising a nonwoven fabric including a plurality of recycled polyester fibers, such as a plurality of staple fibers, is provided. The plurality of recycled polyester fibers may be formed from a post-consumer polyester, a post-industrial waste polyester, or a combination thereof. The covers provide desirable vapor transmission while also providing an improved hydrostatic head. The covers may be provided in a variety of configurations. Methods of forming such covers are also provided.

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.

A smokeless tobacco product includes smokeless tobacco and structural fibers. The structural fibers forming a network in which the smokeless tobacco is entangled. The structural fibers have a composition different from the smokeless tobacco. The tobacco-entangled fabric can have an overall oven volatiles content of at least 10 weight percent. In some embodiments, the structural fibers form a nonwoven network. In some embodiments, fibrous structures of the smokeless tobacco are entangled with the structural fibers.
