Abstract: The present invention relates to a method for producing fiber composites impregnated with a thermoplastic resin to be used as stab and ballistic composite structures. If compared with the manufacturing processes of the state of the art, the method according to the present invention enables to prepare stab and ballistic resistant composite structures in a more efficient way by reducing the complexity of the manufacturing machine and at a lower cost.

Abstract: Nonhalogen-Containing Thermoplastic Polyolefin blends are provided which are either heat resistant and are particularly useful in wire and cable coatings, extruded profiles, sheet form or injection molded part or have an elastomeric behavior and are particularly useful in injection molded part. These blends comprise preferably (1) ethylene n-butyl acrylate glycidyl methacrylate (EnBAGMA) terpolymer, (2) an ethylene propylene rubber (EPDM) grafted with maleic anhydride, (3) a polypropylene homopolymer for heat resistance or a very low density polyethylene for elastomeric behavior or a linear low density polyethylene (LLDPE) or a low density polyethylene or a high density polyethylene or an ethylene-polypropylene copolymer.

Abstract: Se revelan películas, cintas, y fibras hiladas por hilado de masa fundida que comprenden o que se preparan a partir de una composicion que comprende a) por lo menos un polímero de poliamida; y b) entre aproximadamente 0,1 y 20 % en peso de por lo menos un copolímero de etileno como por ejemplo dipolímeros de acetato de etileno/vinilo, terpolímeros de acetato de etileno/vinilo, dipolímeros de (met)acrilato de etileno/alquilo, terpolímeros de (met)acrilato de etileno/alquilo, copolímeros de etileno funcionalizados, copolímeros de etileno/ácido, y sales de los mismos. Las películas, cintas y fibras muestran propiedades mejoradas ante la tension como por ejemplo resistencia a la traccion y elongacion ene el momento de la rotura en comparacion con las composiciones de poliamida sin modificar. También se revelan textiles no tejidos que comprenden o que se preparan a partir de las fibras orientadas hiladas por hilado de masa fundida.

Abstract: Películas, cintas, y fibras hiladas por fusión elaboradas a partir de composiciones que comprenden (a) por lo menos un polímero de poliéster, y (b) entre aproximadamente 1 y 30% en peso de por lo menos un copolímero de etileno como por ejemplo dipolímeros de acetato de etileno/vinilo, terpolímeros de acetato de etileno/vinilo, dipolímeros de etileno/(met)acrilato de alquilo, terpolímeros de etileno/(met)acrilato de alquilo, copolímeros de etileno funcionalizados, copolímeros de etileno/ácido, y sales de los mismos. Las películas, cintas y fibras muestran propiedades mejoradas ante la tensión como por ejemplo resistencia a la tracción y alargamiento a la rotura en comparación con las composiciones de poliéster no modificado. También se describen telas y artículos que se preparan a partir de las fibras descritas.

Abstract: A process for preparation of a tufted polyamide-type fiber carpet is provide d. A primary backing tufted with yarn comprised of at least 85% by weight of fibers selected from the group nylon fibers, wool fibers, and blends thereof is provided. A molten polymer adhesive is provided on the back side of the tufted primary backing, the polymer adhesive consisting of at least 85% by weight of one or more ethylene copolymers each comprised of 50 to 95 weight % of ethylene, and 5-50 weight % of at least one comonomer selected from the group of esters and carboxylic acids. The tufted primary backing and the molten polymer adhesive layer are compressed under a moving belt that applie s a pressure of at least 1 N/cm2 for a period of at least 5 seconds during whi ch time the polymer adhesive remains in a molten state. The molten polymer adhesive then cooled to a temperature below the melting point of said molten adhesive. A secondary backing may be placed over the molten polymer adhesive on the back of the primary backing.
