Abstract: Yarn intended for making up a cut-resistant and abrasion-resistant textile surface, characterized in that it is obtained by spinning high-tenacity polyamide staple fibers, the tenacity of which is greater than 4.5 cN/dtex and the length of the fibers of which is between 40 and 170 mm.

Abstract: The invention concerns a web comprising an intimate mixture of mixed slivers of long reinforcing staple fibres (14) obtained by stretch-breaking and long thermoplastic matrix fibres (15), those different fibres being parallel in the mixture.

Abstract: The invention concerns a yarn comprising a core (A) obtained by coextrusion of a glass multifilament E, R, C or S or more generally of glass silk or basalt and a polymer sheath of the thermoplastic, thermoset, natural elastomer fluorinated or non fluorinated synthetic elastomer type. The fiberglass part represents not more than 60 wt. % of the sheath+filament complex, and the core (A) is wrapped with synthetic multifilaments (B, C).

Abstract: The inventive yarn comprises at least one strand (2) having a reinforcing core made of high-modulus and high-resistance staple-fiber yarn, which is made from organic or inorganic material, and a sheath (4) of long or short, low-modulus standard fibers. The other strands (5) are made from long or short, low-modulus standard fibers and are arranged so as to protect the sheath of the strand(s) having a reinforcing core.

Abstract: Yarn comprising a core (A) obtained by coextrusion of a multifilament of E-, R-, C- or S-glass or more generally of textile glass or basalt filament and of a sheath of polymer of thermoplastic, thermosetting, natural elastomer or synthetic elastomer type, fluorinated or otherwise. The glass fiber part represents at most 60% by weight of the filament and sheath compound, and the core (A) is assembled or twisted with staple fiber yarns composed of synthetic fibers (B).

Abstract: In this tape (15), the fibers are discontinuous and have a length distribution such that the mean fiber length, that is to say the mean length of 50% of the fibers in a specimen, is between approximately 40 and 70% of the length of the longest fiber in the specimen, the fibers being combined by means of a resin (10) or of an adhesive having a fugitive nature. Application to the production of components made of composites.

Abstract: A hybrid yarn is made up of an intimate mixture of spun yarns of reinforcing fibers and spun yarns of thermoplastic matrix fibers. The spun yarns are obtained by cracking with slow, gradual stretching of the multifilaments. After stretching, parallel fibers are wrapped with a continuous thermoplastic filament. The invention may be used to produce hot-stamped parts.

Abstract: A sewing thread, whose twist factor is between 100 and 150, consists essentially of a fixed high-tenacity multifilament core, sheathed with a cover of staple fibers, the unit being wrapped with a multifilament yarn. The process of spinning this sewing thread is performed on a spinning frame. The core yarn and the roving of staple fibers are brought to drawing rolls in the drawing plane, and wrapping yarn is brought to the drawing rolls in an offset manner relative to the spinning plane.

Abstract: A process is provided for producing carbon fiber yarns which comprise an intimate association of carbon fibers having an average length of between 100 and 120 mm. The process comprises transforming tows of multifilaments whose count is between 0.5 and 1 dtex by cracking, by drawing, and controlled breaking to obtain long fibers having an average length of between 100 and 120 mm. These fibers are then transformed on standard spinning equipment for long fibers into a range of yarns which have counts ranging from Mn 1 to Mn 100. The yarns of the present invention can be used for making prepreg fabrics for composites, fabrics for dry and wet filtration, fabrics for making Faraday shields, fabrics for carbonization for carbon/carbon pieces and high-performance seals.

Abstract: Fibrous material comprising an intimate mixture of polybenzimidazole fibers and alloy fibers having a nickel base. The fibrous material further optionally includes high modulus aromatic polyamide fibers. This fibrous material can be used for making packings, protective clothing and protective screens.
