Abstract
A method and device for producing melt-spun continuous threads includes two preparers spaced apart from one another, at each of which a partial quantity of a preparation is applied to the threads. A first preparation is performed upstream of a first draw-off device and a second downstream of the first draw-off device. As a result, high cohesion of the filaments in the thread is achieved.
Claims7
A method for producing melt-spun, continuous, multi-color threads from a plurality of filaments, wherein differently dyed or dyeable filaments are combined in groups of at least two threads and are drawn off, the method comprising at least the following steps:
- performing first a preparation of the threads with a preparation agent at least before a first draw-off device;
- stretching the threads;
- texturing the threads, wherein the threads are crimped;
- cooling the threads;
- compacting the threads without precompaction after the first preparation;
- and
- winding the threads,
- wherein at least a second preparation is performed after the first draw-off device and before the stretching.
A device for producing melt-spun, continuous, multi-color threads from a plurality of filaments, wherein differently colored or colorable filaments are combined in groups of at least two threads, comprising:
- a draw-off device, comprising a galette and a deflection roller;
- a first preparer arranged before the draw-off device;
- first and second galette pairs, wherein the threads are stretched between the galette pairs;
- a texturing device;
- a cooling roller;
- a compacting device arranged without a precompacting device after the first preparer;
- and
- a winding device,
- wherein a second preparer is arranged between the draw-off device and the first galette pair.
