Abstract

Beschrieben wird ein Verfahren zur Herstellung falschdrall-texturierter Garne durch Schmelzspinnen von Polymeren und anschließende Falschdrall-Texturierung, wobei die aus den Polymeren geschmolzenen und nach anschließendem Abkühlen erstarrten Filamente beim Schmelzspinnvorgang mit einer Flüssigkeit beaufschlagt werden, die bei der Falschdrall-Texturierung rückstandslos verdampft.A process for producing false twist textured yarns is described Melt spinning of polymers and subsequent false twist texturing, whereby those melted from the polymers and solidified after subsequent cooling Filaments are subjected to a liquid during the melt spinning process evaporated without residue during the false twist texturing.

Überraschenderweise hat sich gezeigt, daß das Falschdrall-Texturieren von Garnen aus Standardpolymeren nach Aufbringen einer beim Falschdrall-Texturieren rückstandslos verdampfenden Flüssigkeit prozeßtechnisch einwandfrei beherrschbar ist, sofern die Temperatur des Falschdrall-Texturiervorgangs unterhalb des Schmelzbereichs des verwendeten Polymers liegt. Das Aufbringen der Flüssigkeit auf die Filamente während des Schmelzspinnvorgangs ist hierbei erforderliche um das Auftreten von Problemen beim Aufspulen der erstarrten Filamente zu verhindern.Surprisingly, it has been shown that the false twist texturing of yarns from standard polymers after application of a false twist texturing Liquid that evaporates without residue can be handled perfectly in terms of process technology if the temperature of the false twist texturing process is below the Melting range of the polymer used is. Applying the liquid on the filaments during the melt spinning process is required to do this To prevent problems occurring when winding up the solidified filaments.

Somit kann erfindungsgemäß auf die Verwendung sowohl von Spinnpräparationen als auch von Spulölen verzichtet werden, so daß die entstehenden falschdrall-texturierten Garne völlig präparationsfrei sind.Thus, according to the invention, the use of both spin finishes and can also be dispensed with spooling oils, so that the resulting false-twist textured Yarns are completely free of preparation.

Beschrieben werden ferner falschdrall-texturierte Garne, die gemäß einem erfindungsgemäßen Verfahren hergestellt sind, sowie die Verwendung von aus Polymeren schmelzgesponnenen Garnen mit Flüssigkeitsbeaufschlagung zum Falschdrall-Texturieren, wobei Garne gemäß erfindungsgemäßer Definition herangezogen werden.Also described are false twist textured yarns, which according to a are produced according to the invention, and the use of Polymer melt spun yarns with liquid application for False twist texturing, yarns according to the definition of the invention be used.
