INSTALLATION AND METHOD FOR PRODUCING A SINGLE- OR MULTI-LAYER NONWOVEN
The invention relates to an installation and a method for selectively producing a single- or 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.
MULTI-LAYERED FIBROUS STRUCTURES FOR MODERATE TEMPERATURE
An article comprising: (a) one or more nonwoven material layers comprising a lofted fibrous material; and (b) one or more molded material layers having a fibrous matrix, wherein the article is configured to at least partially thermally insulate an item or compartment and the article absorbs external heat or cold to substantially prevent amplitude of temperature fluctuation of the item or within the compartment.
POLYMER FLOOR ELEMENT
A polymer floor element includes a decorative top layer on a substrate made of polymer. The floor element has a rectangular or square surface, for which it is valid that for a strip of the floor element with a first point Q defined as a vertex of the strip, and a point P at a distance of 40 cm with respect to Q along a side of the strip, suspended over a rod with diameter 2 cm with its side on which P and Q are defined, perpendicular to the axis of the rod, so that P is located in the vertical direction at the highest point where the floor element touches the rod. The strip, with point Q along one side, hangs down from the rod under the strip's own weight; the straight line PQ intersects the vertical through P at an angle less than 15°.
DUAL-REINFORCED CONSTRUCTION BOARD
A dual-reinforced construction board is disclosed comprising a core having an upper surface and an opposing lower surface, a first reinforced fibrous facer adhered to the upper surface of the core and a second fibrous facer adhered to the lower surface of the core. Each of the first and second fibrous facer comprise a non-woven mat coated on a first surface with a coating composition. The first fibrous facer and optionally the second fibrous facer further include a reinforcement layer adhered to at least a portion of the first surface of the non-woven mat. The dual-reinforced construction board has a fastener pull-through strength of at least 400 lbf.
BASE MATERIAL FOR MOLDING
The present invention relates to a molding base material (10) with which it is possible to prepare a vehicle exterior material such as an underbody shielding material. As a result of continued investigations, the applicant of the present application found that the objective of the present invention could be achieved by means of a “molding base material including a fiber base material layer (1) and a cover layer (3), wherein the fiber base material layer and the cover layer are integrally bonded to one another by means of a polypropylene-based resin layer (5) present at the interface between the fiber base material layer and the cover layer”, and wherein the fiber base material layer contains sheath-core type composite fibers of which the core portion is a polyester-based resin and the sheath portion is a polypropylene-based resin. That is, it was found, for example, that a vehicle exterior material prepared using a molding base material satisfying this composition does not readily suffer from inter-layer peeling under high-temperature conditions, and has excellent heat resistance.
LAMINATE
A laminated body is disclosed. The laminate body has a leather layer comprising natural leather in which all or a portion of the reticular layer has been removed, a fiber layer comprising natural and/or synthetic fibers positioned at the rear-side of the leather layer, and an adhesive layer between the leather layer and the fiber layer, wherein, in the leather layer, the proportion of the thickness of the reticular layer is 5% or less and the proportion of the thickness of the papillary layer is 95% or more.
FIBER-REINFORCED RESIN COMPOSITE SHEET, FIBER-REINFORCED RESIN COMPOSITE MATERIAL, AND MOLDED RESIN ARTICLE INCLUDING SAME
A fiber-reinforced resin composite sheet of the present invention contains: a polyamide resin film containing a dicarboxylic acid component (a) and a diamine component (b); and a plurality of reinforcing fibers laminated in a state of being oriented in the same direction on the polyamide resin film, the reinforcing fibers being obtained by opening a reinforcing fiber bundle. The dicarboxylic acid component (a) contains 60 mol % or more and 100 mol % or less of terephthalic acid. The diamine component (b) contains 60 mol % or more and 100 mol % or less of 1,9-nonanediamine and 2-methyl-1,8 octanediamine. The fiber-reinforced resin composite sheet has a volume content rate Vf of the reinforcing fibers of 20% or more and 70% or less and a thickness of 20 μm or more and 70 μm or less.
