Definitions
- the invention relates to a method for producing smooth yarn from thermoplastic synthetic threads, in particular smooth polyester yarn, according to which the plastic yarn is fed to a take-off unit by means of a delivery unit, stretched between the delivery unit and, take-off unit, heat-set and finally wound up.
- Smooth yarns made of thermoplastic synthetic threads and especially polyester threads are spun from a plurality of filaments. These filaments are combined into a bundle of threads, prepared and wound up at high speed.
- the flat yarn to be produced obtains its usage properties by stretching.
- the plain yarn is usually fed to a second heated supply unit via a first supply unit and is pre-drawn to a ratio of less than 1.1: 1.
- the flat yarn is heated on the second heated feed unit, for polyester to about 85 ° C. From the second feed unit, the flat yarn is fed to a take-off unit via a heating plate, finally stretched and then wound up.
- the smooth yarn is heat-set on the heating plate, namely the fixing of a decoction shrink or a hot air shrink with a surface temperature between 130 ° C and 170 ° C.
- This multi-stage process is relatively complex, also in terms of the device. The invention seeks to remedy this.
- the invention is based on the object of specifying a simple and inexpensive method for producing smooth yarn from thermoplastic synthetic threads, in particular of smooth polyester yarn, and to provide a device which is suitable for carrying out this method.
- the plastic yarn is preferably when deducted speeds from 300 m / min to 1600 m / min, preferably from 600 m / min to 1000 m / min cold-drawn, at room temperature. Furthermore, the invention provides that the plastic yarn is heat-set between 2% and 40% at a surface temperature of the draw-off unit between 90 ° C and 250 ° C depending on a boil-off shrinkage or hot air shrinkage to be achieved.
- a polyester yarn is used as the plastic yarn, which is drawn from a bundle of threads of undrawn oriented threads and in front of a spinneret with a take-off speed of at least 2500 m / min, preferably from a polyester POY ( Partially Oriented Yarn) with a titer of 40 dtex to 600 dtex.
- Its undrawn polyester yarn is expediently cold drawn with a birefringence of at least 0.023 and an elongation at break between 55% and 180%.
- the invention also includes the production of only a smooth, cold-drawn filament thread made of polyester or polyester POY.
- the invention further relates to a device which is particularly suitable for carrying out the claimed method and is distinguished by a simple and functional design.
- this device has an unwinding spool, a supply unit, a take-off unit and a take-up spool.
- the take-off mechanism can be heated or has a heatable surface for heat setting the plastic or polyester yarn, the heating temperature being adjustable.
- the take-off unit can have a separating roller for the plastic or polyester yarn wrapping around the take-off mechanism can be assigned in order to simultaneously subject the plastic or polyester yarn to a temperature treatment by means of cold drawing in order to adjust the cooking shrinkage or the hot air shrinkage.
- polyester-POY stands for a polyester thread with a titer of about 40 dtex to 6000 dtex, which was melt-spun at a speed of about 2500 m / min to 6000 m / min, preferably 2700 m / min to 4500 m / min.
- the device has an unwinding spool 2, a delivery mechanism 3, a take-off mechanism 4 and a winding spool 5. Between the delivery unit 3 and the take-off unit 4, the polyester yarn 1 is cold drawn with a draft ratio greater than 1.1: 1.
- the cold-drawn polyester yarn 1 is heat-set at the same time on the take-off unit 4.
- the extractor 4 has a heatable surface.
- the heating temperature is adjustable.
- the cooking shrinkage or the hot air shrinkage is set between 2% to 40% depending on the selected surface temperature of the fume cupboard 4, which can be between 90 ° C to 250 ° C
- the take-off unit 4 is assigned a separating roller 6 for the polyester yarn 1 wrapping around the take-off unit 4.
