Publication number: 20090169881Abstract: A method for producing a rough elongate composite element, and a rough elongate composite element formed by the method. In the method, introduced simultaneously into a sheathing device are an essentially solid cord based on an organic material and reinforcing yarns as well as a mixture including a molten thermoplastic and at least one of the following constituents: a reinforcement and a filler, the cord being pulled by a haul-off mechanism downstream from the sheathing device. The cord is sheathed by forming a layer of the adherent mixture onto the cord, the roughness of the sheath formed in this way being created by the sheathed cord leaving the sheathing device.Type: ApplicationFiled: November 30, 2005Publication date: July 2, 2009Inventors: Christophe Ducret, Gerard Tardy, Gilbert Dufayard

Publication number: 20090139601Abstract: A functional elastic composite yarn comprises an elastic member that is surrounded by at least one functional covering filament(s). The functional covering filament has a length that is greater than the drafted length of the elastic member such that substantially all of an elongating stress imposed on the composite yarn is carried by the elastic member. The elastic composite yarn may further include an optional stress-bearing member surrounding the elastic member and the functional covering filament.Type: ApplicationFiled: November 8, 2005Publication date: June 4, 2009Applicant: TEXTRONICS, INC.Inventors: Eleni Karayianni, George W.
