Processes for making fibrous structures and more particularly processes for making fibrous structures comprising filaments are provided.

Processes for making fibrous structures and more particularly processes for making fibrous structures comprising filaments are provided.

A laminate is made by first making by melt-blowing or spunbonding of multicomponent, thermoplastic, and endless filaments a first nonwoven layer lying generally in a plane and having a predetermined shrinkage capacity or potential parallel to the plane and making of thermoplastic and endless filaments a second nonwoven layer also lying generally in a respective plane and having a shrinkage capacity or potential that is smaller than that of the first nonwoven layer. The two layers are directly juxtaposed flatly on each other, and the directly juxtaposed first and second layer are bonded together only at bonded regions while leaving an array of unbonded regions distributed over a surface of the two bonded-together nonwoven layers. Then only the first nonwoven layer is shrunk so that the second layer bunches in the unbonded regions and is there raised transverse to a plane of the bonded-together layers.

A multi-layered web is disclosed that is resilient and/or elastic in the Z-direction. Thus, when the web is compressed, the web assumes a compacted state and then expands to an expanded state when the compressive forces are removed. In one embodiment, the multi-layered web includes a middle layer made from a resilient blend of fibers positioned inbetween two outer layers. The middle layer, for instance, can contain elastomeric fibers, three-dimensional fibers, and/or debonded fibers.

A carrier material includes at least a first thermoplastic fiber layer and a second thermoplastic fiber layer. At least a part of the first thermoplastic fiber layer and/or the second thermoplastic fiber layer at at least one boundary of the carrier material is removed, to provide a first part of a form-fit connection. The carrier material can be used in bituminous roofing membranes, roofing underlayment sheets, carriers for filter media, primary backings for tufted carpets and (cushion) vinyl floor coverings.

Absorbent nonwoven wipes having improved strength and hand feel comprising a non-homogeneous mixture of small diameter polymeric meltblown fibers and absorbent staple fibers with meltblown fiber rich outer surfaces and staple fiber rich inner regions and wherein a minor amount of staple fibers also protrude through the meltblown fiber rich regions. Wet wipes and dispensers for housing the same are also provided.

A spunbond wipe is provided. At least one of upper and lower layers of the spunbond wipe is a spunbond long fiber layer. An intermediate layer of the spunbond wipe is a wood pulp fiber web. Spunbond long fibers of the spunbond long fiber layer are interwoven in the wood pulp fiber web. Also provided is a manufacturing method of the spunbond wipe.

A wipe comprises upper and lower melt-blown fiber webs and an intermediate wood pulp fiber web containing a hot-melt adhesive substance. Melt-blown fibers of the melt-blown fiber webs are interwoven in the wood pulp fiber web. A manufacturing method of a wipe can manufacture a water-absorbing wipe, effectively prevent the wipe from shedding fibers when in use, and effectively prevent agglomeration of short wood pulp fibers after the wipe has absorbed a liquid.

Disclosed is a wipe. Upper and lower layers of the wipe are melt-blown fiber webs, and an intermediate thereof is a wood pulp fiber web, wherein an adhesive is attached to the surfaces of the melt-blown fiber webs and to the interiors thereof that are adjacent to the surfaces, and the melt-blown fiber of the melt-blown fiber webs penetrates into the wood pulp fiber web. Also disclosed is a manufacturing method for the wipe. When the wipe is used, fluffiness and piling phenomena are prevented, such phenomena being caused by mutual disengagement of cementation between the melt-blown fibers under the action of external force since the surface melt-blown fibers are subject to multiple instances of friction.
