A liquid-absorbing multi-layered sheet with a liquid-absorbing central layer and a first and a second outer layer of fibers, tissue or film provided at each their side of the central layer is provided. The central layer is airlaid and includes cellulosic fibers, superabsorbents and heat-adhesive binder fibers. The sheet is peculiar in that the percentage of heat-adhesive binder fibers in the central layer is between 1% and 7% of the total weight of fibers in the central layer. In production, a continuous web with the three layers is conveyed through a heating zone for heating the web, wherein the heating temperature and the heating time are adapted to at least a partial melting of the heat-adhesive binder fibers in the central layer for binding the fibers in the central layer and for binding the outer layers to the central layer.

A method for manufacturing a breathable elastic laminate includes aperturing an elastic film to create an apertured elastic film with a pattern. The pattern includes a plurality of first lanes extending in a machine direction, each of the plurality of first lanes having a plurality of apertures, and a plurality of second lanes extending in the machine direction. Each of the plurality of second lanes is devoid of apertures and has a width of at least twice the width of one of the apertures in the first lanes. The plurality of second lanes alternate with the plurality of first lanes in a cross direction substantially orthogonal to the machine direction. The method includes stretching the apertured elastic film in the machine direction to activate the apertured elastic film and bonding a first side of the activated apertured elastic film to a nonwoven web to create a breathable elastic laminate.

A biaxially stretchable laminated fabric composite material includes a four-way stretchable fabric and a barrier film. The barrier film and the fabric are selectively attached at a plurality of individual bond points. When the fabric is in an unstretched state, random folds are formed in the unbonded regions of the barrier film. When the fabric is in a stretched state, the random folds are partially or fully flattened to allow the biaxially stretchable laminated fabric composite material to biaxially stretch.

A composite tape comprising a first web and a second web welded together according to a welding pattern comprising a plurality of welding points arranged in arrays extending along a first direction and spaced apart in a second direction, perpendicular to said first direction, with adjacent arrays offset from each other in said first direction, and with said welding points in each array arranged in groups spaced apart in said first direction, wherein the first web has a plurality of hollow protrusions alternating with welding points, both in said first direction and in said second direction, and wherein the second web has a plurality of ribs extending along said first direction and separated from each other by said arrays of welding points.

A method of shaping a preform includes: laminating plural dry tape members each including a binder and fiber while partly heat-sealing the dry tape members with the binder to provisionally fasten each dry tape member to an adjacent dry tape member; bending the dry tape members having been provisionally fastened, along a bending line; and heat-sealing the dry tape members having been bent with the binder to manufacture a shaped dry preform. At the laminating, at least one of the followings is satisfied: (i) an amount of heat-sealing with the binder is changed in an area along the bending line, (ii) an amount of heat-sealing with the binder is different between portions adjacent to and on opposite sides of the area along the bending line, or (iii) an amount of heat-sealing with the binder is different between portions adjacent to each other at the bending line as a border.

A breathable and waterproof composite fabric includes a fabric sheet and a waterproof plastic film. The fabric sheet has a first surface, a second surface and a plurality of micropores extending through the first and second surfaces. The waterproof plastic film is made of a non-porous material and has an outer surface, an inner surface bonded to the first surface, and a plurality of hollow protrusions protruding from the outer surface. Each of the hollow protrusions defines a channel having an inner open end at the inner surface and an outer open end distal from the inner and outer surfaces. A method of making the breathable and waterproof composite fabric is also provided.

A filter core and manufacturing method thereof, the manufacturing method has the following steps: adhering a wavy filtering sheet and a flat filtering sheet, pressing the filtering sheets, and rolling the filtering sheets. A part of peaks of the wavy filtering sheet are pressed to lean toward a same side. In particular, two sides of a first end sealing adhesive layer are pressed. Thus, the first end sealing adhesive layer is concentrated, such that the glue is uniformly spread to the two sides. Besides, the pressing on the two sides makes the two sides of the first end sealing adhesive layer adhered securely, thereby preventing the wavy filtering sheet from rebounding upward and forming bubbles. Thus, the first end sealing adhesive layer can be formed with less quantity of glue, which accelerating the cooling and raises manufacture efficiency.

Novel multilayer laminates and lamination methods useful for the production of safety glass are disclosed in which an interlayer is provided between substrates and a porous sealant material is provided in a strip around the perimeter of the interlayer and at least partially in-between the substrates adjacent the interlayer. The space between the substrates is evacuated or de-aired through the porous sealant. The porous sealant is then made into a non-porous, continuous perimeter seal by pressing at or near room temperature or at a moderately elevated temperature to remove pores or gaps. The laminate is further processed at higher elevated temperatures either at or near atmospheric pressure or at elevated pressure to increase the bonding between the interlayer and the substrates and to eliminate most or all of the initial texture on the surfaces of the interlayer.

A method for manufacturing an underlay material (8) to be set under parquet or a laminate, the underlay material including a sheet material layer (1) and a flexible cellular plastic material layer (3) bonded under the sheet material layer, and a bottom surface of the cellular plastic layer being processed for providing an air space, whereby the bottom surface of the cellular plastic material layer (3) is processed by melting the cellular plastic material locally for providing an air space (9) and for simultaneously bonding the cellular plastic material layer to the sheet material layer (1). An underlay material manufactured by such a method is also described.

There is disclosed a laminated, nonwoven fabric and a process for producing such a laminated, nonwoven fabric having desirable fluid holding and fluid release characteristics. The process provides that two sheets of meltblown fiber fabric are produced on forming wire assemblies, cooled at a cooling area, and are then laminated on opposite sides of a sheet of spunbonded fibers using to form the laminated, nonwoven fabric.
