  • Patent number: 9327473
    Abstract: The present invention is directed to a fluid-entangled laminate web and the process and apparatus for its formation as well as end uses for the fluid-entangled laminate web. The laminate web includes a support layer and a nonwoven projection web having a plurality of projections which are preferably hollow. As a result of the fluid-entangling process, entangling fluid is directed through the support layer and into the projection web which is situated on a forming surface. The force of the entangling fluid causes the two layers to be joined to one another and the fluid causes a portion of the fibers in the projection web to be forced into openings present in the forming surface thereby forming the hollow projections. The resultant laminate has a number of uses including, but not limited to, both wet and dry wiping materials, as well as incorporation into various portions of personal care absorbent articles and use in packaging especially food packaging where fluid control is an issue.

    Abstract: An entangled fabric that contains a nonwoven web hydraulically entangled with a fibrous component is provided. The nonwoven web is formed from staple fibers and is creped. For example, in one embodiment, the nonwoven web is a creped, point bonded, carded web. Excellent liquid handling properties can be achieved in accordance with the present invention without resulting in the poor liquid handling capabilities often associated with point bonded nonwoven webs. In fact, the entangled fabric of the present invention can have improved bulk, softness, and capillary tension.

  • Publication number: 20040103507
    Abstract: Provided is a water-decomposable fibrous sheet including fibers containing at least 3% by mass of fibrillated rayon. The fibrillated rayon has a degree of beating of at most 700 cc and has primary fibers of a predetermined fiber length and microfibers extending from the primary fibers. In the fibrous sheet, the microfibers are entangled with at least either of other microfibers and other fibers therein, and the surface friction resistance of the fibrous sheet in dry, measured according to the abrasion resistance test method of JIS P-8136, is at least three rubbing cycles.

  • Publication number: 20040084134
    Abstract: A process for producing a non-woven composite fabric by water-jet entangling. First, at least two webs are formed. These at least two webs include at least one spunbonded web or meltblown web. Then, the at least two webs are consolidated by water-jet entangling into a non-woven composite fabric. Compared to a conventional process using thermal bonding to consolidate webs, since the present invention uses water-jet entangling to consolidate webs, the non-woven composite fabric produced from the present invention has superior softness. In addition, the non-woven composite fabric produced from the present invention can be further processed to produce various non-woven composite fabric products such as disposable diapers, sanitary napkins, panty liners, and artificial leather, all with superior softness.

  • Publication number: 20040033749
    Abstract: A composite facer material for use with cementitious wallboards, where the composite facer is embedded in a top and bottom face thereof. The composite facer material, in a most preferred embodiment, comprises two layers. The first layer is preferably a carded polyester nonwoven mat, which is bonded to a second layer comprising preferably a tri-directional laid scrim fabric reinforcement layer made of continuous glass fibers. The two layers are preferably bonded together using an acrylic adhesive, which offers superior adhesion between the layers as well as superior adhesion between the composite facing material and the cementitious core.

  • Publication number: 20030211800
    Abstract: A composite nonwoven fabric manufactured by joining a fibrous web that comprises wood fibers, or a mixture of wood fibers and synthetic fibers, to a spunlaid or other nonwoven baseweb by means of a hydroentanglement process. The spunlaid nonwoven web, which may be made of a polyester such as a poly (ethylene terephthalate) or of a polyolefin such as polypropylene, is a less-than-fully bonded web, which may be produced by a method in which the thermal calendering is effected at lower than normal temperatures, in particular temperature lower than the melting point or softening point of the polymeric material from which the spunlaid nonwoven web is made. The strength of the composite fabric may be significantly greater than that of the spunlaid nonwoven web itself, in certain embodiments the base web contributes no more than about 45% of the strength of the composite fabric.

  • Patent number: 6592960
    Abstract: A method of manufacturing a non-woven fabric which is bulky caused by fiber-raised construction on the surface of a non-woven fabric includes adhering a non-woven web with its surface layer portion containing an easy-to-heat-melt component showing a property to be adhesive as heated to a smooth surface heated at the temperature for the easy-to-heat-melt component to show a property to be adhesive with the surface layer portion in contact with the smooth surface, and then raising the fibers of the non-woven web by peeling the non-woven fabric like web off the smooth surface so that a fiber-raised bulky state is generated, whereby a fiber-raised bulky structure is formed on the surface of the non-woven fabric.
