摘要:
Polyolefin fibres coloured with copper dyes are disclosed. The above are characterised by a light-fastness according to DIN EN ISO 105-B02 (at 50°C and 144 h illumination) of at least 5, a wash-fastness according to DIN EN ISO 105-CO8C of at least 4 and a dry rubbing-fastness according to DIN EN ISO 105-X12 of at least 3. Such polyolefin fibres are particular suitable for production of a textile. A particularly advantageous method for production of said polyolefin fibres or textiles is characterized in that said polyolefin fibres or textiles made from polyolefin fibres are subjected to an adequate duration of plasma treatment before the dyeing with copper dyes. Said polyolefin fibres coloured with copper dyes are characterised by particularly good light-, wash- and rubbing-fastness.

The invention relates to a cross-wind bobbin (1) wherein the helical lines in which the yarn (4) is wound have a different pitch in adjacent positions. The winding ratios are selected in such a way that the amount which is drawn off is greater when the draw-off point is displaced from the draw-off side to the base than the amount which is drawn off when the draw-off point is moved from the base to the draw-off side.

The invention relates to a rotating thread guide (1) for ring spinning frames, said thread guide being arranged at a distance (4) above the upper end (31) of the ring spindle (3) and being coupled to the ring spindle (3) by means of a magnetic field of force, in such a way that the thread guide (1) rotates at the same rotational speed as the ring spindle (3). The inventive thread guide is embodied as a twisting element (11) comprising a driving element (13) for the continuous threads.

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.
