Abstract:
A sheet of unidirectionally-oriented fiber strands includes unidirectional fibers, bonding fibers interwoven with the unidirectional fibers to form a fiber panel, and thermoplastic film laminating the fiber panel there between. In one embodiment, a second sheet of laminated unidirectional fibers is joined to the first sheet of laminated unidirectional fibers with the unidirectional fibers running in a second direction as compared to the first fibers. In yet another embodiment, individual laminated sheets of unidirectional fibers are stitched together to form packets of sheets which may be used singularly or multiple packets may be bundled together.
Abstract:
A laminated fabric floor product having an encapsulated fabric scrim within a vinyl resilient flooring structure. The laminated fabric floor product structure includes a PVC calendered base, a first hot melt film, a fabric, a second hot melt film, a calendered clear film, and a high performance coating. Traditional foamed and non-foamed substrates used in the flooring industry can be used in addition to the calendered base. All types of fabrics and scrims can be encapsulated. The fabrics can be both woven and non-woven types. Open scrims can be used with base layers that are printed or have a visual pattern so that design features and colors can be seen through the open areas of the scrim. The fabric layer can be printed with a design pattern and adhered to the base layer or substrate by the first hot melt adhesive film layer. The clear layer is adhered to the fabric layer by the second hot melt adhesive layer.
Abstract:
High strength polyethylene fibers and their applications, for example, chopped fibers, ropes, nets, ballistic materials or items, protective gloves, fiber reinforced concrete products, helmets, and other products obtained therefrom, in which the fiber is characterized in that: it contains a high molecular weight polyethylene consisting essentially of a repeating unit of ethylene; it has an intrinsic viscosity number of 5 or larger and an average strength of 22 cN/dtex or higher; and the measurement of the fiber by differential scanning calorimetry (DSC) exhibits a temperature-increasing DCS curve having at least one endothermic peak over a temperature region of 140null C. to 148null C. (on the low temperature side) and at least one endothermic peak over a temperature region of 148null C. or higher (on the high temperature side) or the number of frictions until the fiber is broken in an abrasion test according to method B for measuring abrasion resistance in the Testing Methods for Spun Yarn (JIS L 1095) is 100,000 or larger.
Abstract:
The present invention relates to a process for producing a laminated sheet comprising an alumina fiber precursor, which process comprises spinning out an alumina fiber precursor from a solution mainly comprising an aluminum compound, falling and stacking said alumina fiber precursor on the surface of an accumulator to form a thin lamina sheet of alumina fiber precursor, continuously pulling out said lamina sheet from the accumulator, transferring the resultant lamina sheet to a folding device, and folding the sheet by a predetermined width while stacking the folded sheet and continuously moving the stacking sheet in the direction orthogonal to the folding direction.
Abstract:
There is disclosed an absorbent article including an absorbent layer and a liquid-permeable surface sheet placed on a liquid-receiving side of the absorbent layer for introducing excreted liquid from the human body to the absorbent layer. The surface sheet is of a corrugated configuration to have valleys and peaks extending in a longitudinal direction of the article and alternately arranged in a transverse direction perpendicular to the longitudinal direction. Each valley has a connecting part raised to connect between two adjacent peaks.
Abstract:
A multilayer construction that includes a first layer that includes water sensitive thermoplastic polymer and a second layer disposed on the first layer, the second layer including superabsorbent polymer.
Abstract:
A plasterboard having a plaster-based core, wherein the plasterboard is provided on at least one of its sides with a glass-fiber mat facing, the mat facing being coated on an external face with a coating composition including a mineral filler, with the exception of hydratable calcium sulphates; and an organic or mineral binder.
Abstract:
The object of the invention is to provide a process for producing a woody composite material having strength endurable for use as a structural material, even when using short woody chips of 15 cm or less in length. This invention relates to a process for producing a woody composite material which comprises the steps comprising blending woody chips of 1 to 15 cm in length with a binder, piling up the woody chips so as to be oriented in the longitudinal direction thereof to form a mat, and pressurizing and heating the mat from a direction perpendicular to both the longitudinal direction and vertical direction of the woody chips.
Abstract:
The purpose of the present invention is to provide a shell laminated structure realizing a further light weight formation of a helmet while improvement for shock absorbing characteristic is assured. There is provided a laminated structure in which either the net-like member or the sheet-like member having many holes is placed at an entire region of the shell having a reinforcing base material or between the laminated layers at a part of the shell in such a manner that the sheet-like member is extended along the layer to which its front and rear surfaces are faced, bitten into the layer and fixed. With such an arrangement as above, a further light weight formation of the shell is realized while a high safety characteristics of the helmet is assured.
Abstract:
A method and apparatus for orientation of block copolymer microdomains via rapid solidification. Rapid solidification from a solvent may include directional solidification and/or epitaxy to form patterns of microdomains in a film of block copolymer. Microdomains may include various structures formed by components of a block copolymer, such as vertical lamellae, in-plane cylinders, and vertical cylinders, and may depend on film thickness. Orientation of structures in microdomains may be controlled to be approximately uniform, and spatial arrangement of microdomains may be controlled.
