摘要： A yarn-twisting device (10) for twisting multifilament yarns comprises a yarn channel (20) and yarn guides (15, 16) arranged at a certain distance from the inlet and outlet of the yarn channel so as to press the yarn against the yarn channel when the compressed air supply is interrupted in such a way that the yarn in the yarn channel runs parallel to the longitudinal direction of the latter and the straight sections of yarn between the inlet and outlet of the yarn channel and the yarn guides form an acute angle with the sections of the geometrical longitudinal axis of the yarn channel (20) located outside the yarn channel. In addition, the blowing angle of the blower nozzle is less than 90°. The maximum length of the yarn channel (20) is 40 mm for smooth yarns and 30 mm for textured yarns. The maximum distance between the yarn guides (15, 16) and the yarn channel (20) is 30 mm. Very high yarn feed speeds and excellent twisting of the yarn are achieved.

摘要： Verwirbelungsvorrichtung (10) zum Verwirbeln von Multifilamentgarnen. Sie weist einen Garnkanal (20) auf. In Abständen von der Ein- und Austrittsmündung des Garnkanals sind Garnführer (15, 16) so angeordnet, daß durch sie das Garn bei abgestellter Druckluftzufuhr so an den Garnkanal angelegt wird, daß es sich im Garnkanal parallel zu dessen Längsrichtung erstreckt und die geraden Garnbereiche, die sich zwischen den Ein- und Austrittsmündungen des Garnkanales und den Garnführern befinden, unter spitzen Winkeln zu den außerhalb des Garnkanales befindlichen Bereichen der geometrischen Längsachse des Garnkanales (20) geneigt sind. Ferner ist der Blaswinkel der Blasdüse kleiner als 90°. Die Länge des Garnkanales (20) beträgt für glatte Garne maximal 40 mm und für texturierte Garne maximal 30 mm. Die Abstände der Garnführer (15, 16) vom Garnkanal (20) betragen maximal 30 mm. Es gelingen besonders hohe Garnvorschubgeschwindigkeiten und besonders gute Verwirbelung des Garnes.

摘要： The invention relates to a method for the production of a double- or multi-component multifilament yarn, the components of which comprise differing shrinkage properties, whereby at least one component irreversibly lengthens on the action of heat. The yarn components are each produced loop-free in a continuous manner as a straight yarn and then combined to give a combination yarn. The ready-to-use, loop-free combination yarn is wound on a spool for further use. The length change property may be initiated by means of a heat treatment after processing to give a textile fabric. The device comprises a collector for each component, followed by parallel working processing devices for the separate processing of each of the components. The processing device for the extending component comprises a drawing field formed by drawing rollers and a staged heating. The processing device for the shrinking components has a drawing field formed by drawing rollers. A delivery device for collating the components is provided, also a connecting device and a winding device.

摘要： The invention relates to a woven fabric, in which at least one of the intersecting yarn systems contains a differential shrinking yarn (C), which consists of at least one decorative component (A) that elongates irreversibly during thermal treatment and at least one shrinking component (B), which contracts during thermal treatment. The components (A) and (B) are interconnected by means of entangled knots. The number of entangled knots per metre of yarn (C) in the finished woven fabric corresponds to the number of yarns in the intersecting yarn system. The woven fabric is produced in such a way that the components of the differential shrinking yarn are interconnected by air entanglement and in the finished woven fabric contain Ymin>98+0.7x entangled knots. After the entanglement process, the unsized yarns are interwoven as a warp with a weft in such a way that the number of weft yarns in the finished woven fabric is (X). The woven fabric obtained in this manner is subsequently thermally treated.
