Abstract: Curable compositions comprising a substance that produces a base when exposed to radiation and a polymer molecule that contains silicon-hydrogen bonds which react with hydroxyl groups under the action of the base to form silicon-oxygen bonds (Si--O) and hydrogen molecules. These compositions cure when exposed to radiation. A pattern can be formed by placing a mask between a coating of the composition and the radiation source during this exposure episode and thereafter dissolving the uncured composition. The compositions have little weight loss during their cure, they can be cured by low intensity radiation, and they yield heat-resistant cured products.

Abstract: A floor mat has tufts made of a yarn which is formed with a monofilament core around which a multifilament yarn is air entangled. The resulting yarn is sufficiently stiff to clean dirt off of the shoes of passers by, yet is easily cleaned. The monofilament core is a polypropylene between 600 and 1200 denier, preferably about 1095 denier. The multifilament yarns entangled around the core are also polypropylene and total about 160 filaments and about 4800 denier. The air entangling is accomplished using higher than normal air pressure (i.e., about 110 p.s.i.).

Abstract: Apparatus for producing a breathable high strength, paper-plastic film laminate fabric sheeting, capable of being cut and sewn to form medical gowns and other garments. In this apparatus, a web of metallized paper and a web of oriented synthetic plastic film whose inner surface is corona-discharge treated before being coated with a water-based adhesive are concurrently fed in superposed relation into combining rolls to effect cold lamination of the webs to yield a laminate sheeting in which the orientation of the film web is unimpaired. The laminate sheeting emerging from the combining rolls is then foraminated to render the sheeting permeable only to moisture vapor whereby the foraminated sheeting has fabric properties and can be tailored to form garments. To enhance these fabric properties, the foraminated sheeting is embossed to impart greater bulk thereto.

Abstract: Multicomponent thermoplastic continuous filaments are provided, including hollow core multicomponent filaments. The filaments are at least partially splittable into smaller filaments in the absence of mechanical treatment or application of high pressure water jets.

Sub-denier and micro-denier filaments of low orientation can be produced from relatively high molecular weight polymers to produce nonwovens of surprising strength, barrier, and cover.
