- Figure 1 shows an individual machine position M one of a plurality of such Machine positions M existing device for the production of staple yarn from filament yarns.
- the tension of the filament yarns can be monitored and be controlled to a constant value, if the quality of the bobbins very bad or the feed bobbins are different (for example, with respect to feed bobbin end titer, Number of filaments, color of feed bobbins).
- the regulation of the voltage is optional and depends on the feed bobbins.
- the filament yarns 1 are combined into a filament yarn F, and this enters a draw zone SZ formed by two conveyor rollers 2 and 3, which for the orientation of Fibers is required.
- a draw zone SZ formed by two conveyor rollers 2 and 3, which for the orientation of Fibers is required.
- the filament yarn F enters a cooling zone with an optional cooling device 4, in which it is from the temperature of the heated rollers 2 and 3 to ambient temperature is cooled.
- the cooling device 4 is very important, if one with very high Speed produces, at low speed, the filament yarn F in the cooling zone be cooled without cooling device. This means that the use of the cooling device from the production speed and the temperature of the rolls 2 and 3 depends.
- the filament yarn F passes through at least two, as shown four, spaced rollers 5, 6, 7 and 8, each consisting of a conveyor roller and one or consist of two pressure rollers.
- the rollers 5, 6, 7 and 8 form three stretch breaking zones SB1 to SB3, of which the second and the third are optional.
- the in the with an arrow A designated Garnlaufraum foremost roller 8 is at a higher speed driven as the roller 7, this at a higher speed than the roller 6 and This at a higher speed than the roller 5, causing the filament yarn in Each stretch breaking zone SB1 to SB3 a tensile force is applied.
- the length of the first Stretch breaking zone SB1 is greater than the length of the second stretch breaking zone SB2 and its Length is greater than that of the third stretch breaking zone SB3.
- the first stretch breaking zone SB1 all filaments of the filament yarn F are torn and thereby converted into fibers.
- the number of fibers in the yarn cross-section is defined by the ratio of the speeds of the rollers 5 and 6 (V 6 / V 5 when V 6 denotes the speed of the roller 6 and V 5 the speed of the roller 5), by the number of feed bobbins and the Number of filament yarns 1 per supply bobbin determined.
- the distance between the rollers 5 and 6 determines the fiber length.
- dtex decitex, that is the weight in grams per 10'000 meters of yarn.
- the optional second and third stretch breaking zones SB2 and SB3 serve for a renewed partial refraction of the now fibers and for further reduction of the fluctuation width of the fiber length and the number of fibers in the yarn cross section.
- this solidification which takes place through a nozzle 9, we obtain a staple G with the desired optical and physical properties and the desired grip.
- the for the solidification of the sliver to the stacking yarn G required solidification stress is generated by a draw roll 10.
