Abstract:
The present invention relates to a unidirectional reinforcement and a method of producing a unidirectional reinforcement. The unidirectional reinforcement of the present invention may be used in all such applications where high quality and strength is required. The unidirectional reinforcement (2, 4) of the invention comprises transversely arranged thin discrete flow passage forming means (6) for ensuring good resin flow properties in a direction transverse to the direction of the unidirectional rovings.
Abstract:
An assembled intermediate is described comprising a fluid transport element proximate an absorbent material. The fluid transport element comprises a thermoplastic nonwoven web comprising a plurality of coiled filaments having an average diameter of 200 to 500 microns interengaged by means of intermittent bonds. The web preferably has certain properties such as a thickness of 3 to 20 mm, a density ranging from 0.02 to 0.10, and a work of compression of no greater than 20 kJ/m 3 . Also described are articles comprising such assembled intermediate.

Abstract:
This invention relates to a thin reinforced nonwoven fabric having ridges and grooves for fire blocking an article and articles containing such fabrics. When exposed to heat or flame, the fabric is capable of increasing to a thickness that is at least 1.5 times its original thickness. The fabric comprises an open mesh scrim having a having crimped, heat resistant organic fibers compressed thereon and held in a compressed state by a thermoplastic binder, on which is imparted a ridge and groove structure. When subjected to high heat or flame, the binder in the structure softens, releasing the restrained crimped fibers and any ridges and grooves and allowing the thickness of the fabric to increase.
Abstract:
This invention relates to a thin reinforced nonwoven fabric for fire blocking an article, articles containing such fabrics, and methods for making the fabrics and fire blocking the articles. When exposed to heat or flame, the fabric is capable of increasing its thickness by at least three times. The fabric comprises an open mesh scrim having a having crimped, heat-resistant organic fibers compressed thereon and held in a compressed state by a thermoplastic binder. When subjected to high heat or flame, the binder in the structure softens and flows, releasing the restrained crimped fibers and allowing the thickness of the fabric to increase dramatically.
Abstract:
The invention is directed to a composite sheet suitable for use as artificial leather or a precursor to artificial leather, where both surfaces have a napped or brushed appearance. The composite sheet comprises a low-density, lightly bonded non-woven web that is stitch-bonded and bulked such that the stitch-bonding yarns are not visible to the naked eyes without the need of post-processing steps to hide the yarns. The composite sheet may have binder resin(s) dispersed therein and activated.
Abstract:
A spring structural resin molded product capable of eliminating the peeling of the fused part of the spring structure resin molded product by uniformly distributing cooling water throughout the entire surface of a chute to eliminate the overcooling and insufficient cooling of a three-dimensional structure by the cooling water and deeply drawing the width of the melting and continuous three-dimensional structure, and a device and a method for forming a surface layer on the spring structure resin molded product. The cooling water (C) is fed between a water permeable sheet (55) and a sloped plate (51a) to penetrate the cooling water (C) into the upper surface of the water permeable sheet (55) so as to form a cooling water upper layer (M). The three-dimensional structure (3) is supported on the cooling water layer (M) to form the surface layer so as to adjoin continuous adjacent lines with each other.
Abstract:
The present invention provedes nonwoven fiber materials, and methods for making the same, useful for loop materials in hook and loop mechanical attachment systems, the nonwoven materials having crimped monocomponent fibers having substantially circular cross sections, and the webs may further contain uncrimped fibers. The invention also provides disposable articles comprising nonwoven loop materials including disposable personal care absorbent articles such as diapers, feminine care sanitary napkins, and adult incontinence articles, and disposable protective articles such as surgical drapes and gowns and other protective apparel.

Abstract:
Die Erfindung betrifft ein Verstärkungsmaterial, gebildet aus volumisierten Fasern, die in Form einer Matte oder eines Geleges zusammengefasst sind. Die volumisierten Fasern unterscheiden sich hinsichtlich des Materials oder des Grads der Volumisierung. Alternativ oder ergänzend werden nicht volumisierte Fasern eingesetzt. Beim Verfahren zur Herstellung des Verstärkungsmaterials werden die in einem Roving, Garn oder schwach gedrehten Zwirn parallel angeordneten endlosen Elementarfäden mit hohem Elastizitätsmodul mit einer wässrigen bindehaltigen Suspension von Partikeln der ungeblähten Vorstufe der Hohlkügelchen aus Kunststoff einer Teilchengröße von 5 bis 10 µm aufspreizt oder von einander entfernt und die entstandenen Zwischenräume weitgehend mit den Partikeln ausfüllt und das so erhaltene Material für die erforderliche Dauer der für den Blähprozess der Partikel der Vorstufe erforderlichen Temperatur aussetzt und diese zur Matte unter Verwendung unterschiedlich stark oder nicht aufgeblähter Rovings, Garne oder schwach gedrehten Zwirne und/ oder unter Verwendung von Rovings, Garnen oder schwach gedrehten Zwirnen, die aus anderen Materialien bestehen, weiterverarbeitet. Das Verstärkungsmaterial wird zur Herstellung von Leichtlaminaten aus Duroplasten verwendet. Gegenüber dem Stand der Technik lassen sich besonders belastbare Leichtlaminate herstellen.
Abstract:
A fabric for the forming, press and dryer sections of a paper machine, for use as a reinforcing base for a polymeric-resin-coated paper-processing belt or as a corrugator belt, or in other industrial settings where a material is being dewatered, is formed from a monofilament yarn (16), which is spirally wound in the form of a closed helix (26), adjacent turns thereof being abutted against and joined securely to one another. The monofilament yarn has a first side and a second side which are oppositely and correspondingly shaped, so that, when spirally wound in a plurality of turns, the first side fits closely into or against the second side of an adjacent and abutting turn, and adjacent spiral turns are secured to one another at the abutting first and second sides to form the fabric.
