Yarns And Mechanical Finishing Of Yarns Or Ropes
(AREA)
Abstract
Process for making a voluminous yarn, characterized in that the latter comprises a coating of protruding filament yarns, whose process encompasses feeding a twisted yarn to a high velocity jet of fluid and preventing the yarn from losing any substantial amount of its yarn. Torsion until the jet has been reached, application of a false straightening to the yarn by means of the jet, projection of the fluid at a speed close to that of the sound to undulate the filaments of the yarn and provide a multitude of strands of protruding filaments, removal of the yarn from the jet, after a run through the lower jet to the length of the shorter and new twisted filament of the yarn adjacent to the jet to achieve the undulations of the filaments and their ends in place.
