Definitions
- End titer means the titer after stretching.
- Such a method is known from DE 195 29 135.
- Technical polyester yarns in the overall titer range from approximately 100 dtex to 1100 dtex or larger can be produced from the polyester filaments produced by this known method, in a particularly efficient manner.
- EASL means "elongation at specified load” and HAS "hot air shrinkage”.
- the invention has for its object a method for Manufacture of polyester yarns described above To create embodiment, according to which polyester filaments with the required dimensional stability taking into account of a particularly low shrinkage to let.
- polyester filaments are treated in the countercurrent zone at a temperature of 100 ° C. to 199 ° C., preferably 120 ° C. to 170 ° C., and pre-stretched to produce a crystallinity of> 24% ,
- pre-stretch the polyester filaments it is possible to pre-stretch the polyester filaments to produce a crystallinity of 25% to 29% or even 30% to 50%.
- the polyester filaments and the yarns made from them are particularly stable and not only have the reference elongation required for dimensional stability, but also extremely low shrinkage values, so that the DS values and consequently dimensional stability can be achieved with ease.
- the polyester yarns produced by the process according to the invention are particularly suitable for technical uses and in this connection in particular for the production of fabrics.
- the polyester filaments are expediently blown at a temperature of 200 ° C. to 350 ° C., preferably 220 ° C. to 270 ° C.
- the polyester filaments are not only passed through the countercurrent heating zone in an unbundled orientation, but also with an air volume of 5 m 3 / h to 50 m 3 / h, preferably 26 m 3 / h to 40 m 3 / h in countercurrent blown and pre-stretched.
- the only figure shows a device for manufacturing of fully oriented technical polyester yarns. Is to a spinning device 1 with an extruder 2 and Spinning beam provided as a spinneret 3.
- the extruder 2 supplies the spinneret 3 with polyester melt.
- To the spinneret 3 is followed by a reheater zone 4. It takes place then a cooling zone with blowing.
- To the cooling zone 5 is followed by a counterflow heating zone 7, in which the unbundled Blown polyester filaments 8 in counterflow to produce a crystallinity of > 24%.
- a preparation application device closes 9 with thread bundling after leaving the counterflow heating zone 7 on.
- the counterflow heating zone 7 are heatable Subsequent to godets 10.
- the godets 10 are different Drivable and enable speeds the post-stretching of the polyester yarns.
- the godets 10 is a winder 11 for the post-stretched Polyester filaments 8 arranged which at a winding speed from 5000 m / min to 8000 m / min can be.

Description
- die Polyestergarne im Wege einer Bündelung von schmelzgesponnenen Polyesterfilamenten erzeugt werden, ferner
- die Polyesterfilamente hinter einer Spinndüse in einer Kühlzone auf zumindest Erstarrungstemperatur abgekühlt und anschließend zum Zwecke des Verstreckens in einer Gegenstromheizzone auf eine Temperatur oberhalb des Glasübergangspunktes erwärmt werden, wobei
- die Polyesterfilamente zur Erzeugung der erforderlichen Streckspannung in ungebündelter Ausrichtung durch die Gegenstromheizzone hindurchgeführt und von einem gasförmigen Medium im Gegenstrom angeblasen und vorverstreckt werden, wonach
- die Polyesterfilamente mit einem Endtiter von 1,0 dtex bis 7,5 dtex anschließend bei Temperaturen von 80 °C bis 250 °C in einem Streckverhältnis von 1 : 1,5 bis 1 : 1,15 nachverstreckt werden, und wonach
- die Polyesterfilamente abschließend mit einer Aufwickelgeschwindigkeit von 5000 m/min bis 8000 m/min aufgewickelt werden.
