Definitions
- the invention relates to a method for producing a cold drawn, smooth polyester filament thread made of POY with an intrinsic viscosity of 0.6 to 0.9 dl / g and a polyester filament thread produced by the method.
- a smooth multifilament filament thread is to be understood as a non-textured filament thread which retains its uncurled flat shape even after boiling in water.
- Polyester is to be understood as a thermoplastic which was produced from at least 85% by weight of terephthalic acid and ethylene glycol.
- Polyester-POY Partially Oriented Yarn
- the spinneret can be drawn off directly by means of the spooler or a pair of rollers can be connected in between.
- the pair of rolls then runs at the same or slightly different speed than the winder, which is used to control the thread tension in order to improve the winding structure.
- the exact spinning When it comes to the speed of a good POY, it depends on various spinning conditions, but above all on the fibril titer. For a fibril titer of 1 dtex the lower limit is more correct, for a fibril titer of 10 dtex the upper limit.
- the delivery roll can be unheated for stretching or have a temperature of up to 70 ° C.
- Homogeneous cold drawing should be understood to mean that the draw ratio must be chosen so high that there are no undrawn or insufficiently drawn, i.e. Stretched areas may be present under the set stretch ratio, which e.g. can be recognized by the Uster%, which should generally be ⁇ 1.4. For POY from the specified speed range, this means that the draw ratio must be at least 1.8 depending on the spinning speed.
- V A the speed of the take-off
- the object of the invention is to provide a method with which a polyester filament thread can be produced which does not have the disadvantages mentioned and also has a high initial modulus, high strength and low shrinkage.
- the object is achieved according to the invention by the feature of claim 1 and is characterized in that the POY is stretched with a constant stretching ratio between 1.8 and 2.5 kAit and then relaxed with a constant advance of between 3 and 10%.
- Relaxing in dry medium has several advantages over wet relaxation. It brings significant simplifications in terms of production technology, such as avoiding a drying stage, saving energy, no machine pollution, and no burden on the air conditioning due to the release of water vapor.
- Threads are obtained which only change insignificantly in their force-elongation behavior compared to the starting material during further thermal treatment. Such an effect was not expected from the start.
- a high initial modulus of> 800 cN / tex has the advantage that the risk of damage due to known thread tension peaks occurring in the weaving, knitting or knitting process is significantly reduced in the manufacture of textile fabrics. In many cases, a thread with a lower initial modulus will no longer meet the requirements imposed by the high speeds of the processing machines. It is therefore expedient to produce an initial modulus of 800 to about 1200 cN / tex and higher with a relatively low-viscosity starting polymer. At the same time, a reversibility limit above 9 cN / tex of thread tension due to further processing should be used pick up pointed. Such peak tensile force lead to defects in the fabric and thus to a reduction in production output. The highest possible reversibility limit is sought.
- the reference strains (D45) before and after the treatment in boiling water is less than 20%, in particular less than 18%, preferably less than 17%.
- the reference elongation (D45) is expediently chosen to be the elongation which is measured at 45 cN / tex and can be regarded as a measure for characterizing the KD profile of the threads.
- the thread according to the invention should simultaneously meet the following conditions:
- Such a thread is also said to have a thermal shrinkage of less than 7% at 160 ° C.
- the largely shrunk thread has the advantage that in the case of bobbin dyeing, it can be twisted directly onto a perforated dye tube without steaming and rewinding.
- a polyester POY with the intrinsic viscosity of 0.67 dl / g serves as the starting material for all examples.
- a suitable polyethylene terephthalate mass was melted at 285 ° C in an extruder and spun at 3100 m / min through nozzles to a polyester POY with the titer dtex 140 f 24 glossy round, cold stretched on a stretching machine in a ratio of 1: 2.12 with a stretching pen and then relaxed at 5% lead.
- the relaxation was carried out using a plate heater of 20 cm in length at 225 ° C.
- the thread is then swirled according to a swirling intensity of approx. 20 knots / m.
- the delivery speed before stretching is 203.7 m / min, in front of the relaxation zone 431.8 m / min, the take-off speed ascertainable after relaxation is 411.2 m / min.
- the resulting thread is wound up. Examples 2 and 3
- polyester filament threads according to the invention are described by their characteristic KD curves in FIGS. 2-4. Show it:
- Fig. 1 is a schematic representation of the inventive method
- reference numeral 1 is a first delivery plant
- the delivery plant 1 is a second delivery plant
- a heater 3 is arranged between the delivery unit 2 and a take-off unit 4 with a separation roller 4 ', which is followed by a winding unit.
- An undrawn polyester POY 5a is taken up by the delivery unit 1 and cold-drawn by the delivery unit 2 in a stretching zone 5b via a stretching pin 1a.
- the take-off unit 4 runs at a lower speed than the delivery unit 2, as a result of which the drawn thread passes through the heater 3 with an adjustable advance in a relaxation zone 5c. The result is a hot-relaxed thread with the properties according to the invention.
- Fig. 3 shows practically the same curve as Fig. 2 with a higher titer.
- the thread according to the invention is particularly suitable for use for sewing threads, sewing and embroidery threads for clothing textiles, binding threads for weft-knitted articles and as high-modulus shrinkage yarn for semi-technical articles such as, for example, light coating fabrics.
- the thread is also suitable for use with cover sheets, geotextiles and curtains.
