Definitions
- the invention relates to a process for the continuous production of a multifilament, stretchable weft yarn from polyester POY filaments for tire cord fabric, and to a weft yarn produced by the process.
- a polyester POY (partially oriented yarn) is a yarn made from 2800 to approx. 4200 m / min by melt spinning polyester.
- the object of the invention is to provide a technically simple and economical method for producing a high-stretch polyester weft yarn for tire cord fabric.
- Another task is to provide a weft yarn with a high elongation, which is retained even after extreme thermal stress. At the same time, the yarn should have very low thermal shrinkage and the longest possible run length per unit weight.
- polyester POY filament with an initial titer of dtex 170-260 is swirled with a compressed gas and immediately thereafter shrunk with an advance of 40-80% at 230-240 ° C.
- the threads must lie as flat as possible in the cord fabric, so that there are no undesired elevations at the crossover points warp / weft which are coated unevenly during the dip treatment. With a titer below 170 dtex, the tensile strength is too low and the reversibility limit is inadequate.
- the heat shrinkage is expediently carried out at 220-235, in particular at 230-235 ° C., for a period of at least 0.2 seconds, preferably in a convection heater.
- This has the advantage that a reversibility limit of greater than 3 cN / tex results and a sufficient roughness or sliding resistance is guaranteed.
- high-tensile weft yarns made from shrunk polyester POY tend to elongate in the event of a subsequent thermal load, such as those that are subjected to cord fabric during impregnation. This elongation can lead to uneven cord fabrics, which can be difficult for further processing.
- the weft yarn according to the invention simultaneously satisfies the following conditions: the surface of the weft yarn is rough and slip-resistant, the tensile strength> 7 cN / tex, elongation 170-270%, and the thermal shrinkage (at 160 ° C.) in the range + 2% - minus 2%.
- the number of knots is more than 25 knots / m. At less than 25 knots / m, the fibril bandage is not sufficiently compact, which can result in drainage problems and dip deposits.
- the weft yarn After a heat-free heat treatment at 235 ° C. for 2 minutes, the weft yarn has a residual elongation of at least 110% and a thread elongation of less than 5%.
- Example 1 shows the properties of the yarn according to the invention after shrinking without and with 5% post-stretching.
- Examples 2-4 relate to the production conditions according to the invention without post-stretching.
- Polyester-POY master thread dtex 190f36
- Polyester-POY master thread dtex 260f48 intermingling pressure: 2bar
- the weft yarn according to the invention has, in addition to the one-step process, with swirling, shrinking and post-stretching being carried out continuously in one process step, in particular a strong reduction in the elongation tendency after additional heat treatment at 235 ° C., which makes it outstandingly suitable of a weft yarn for use in tire construction. It is surprising that the roughness or the pushing strength can be achieved without twisting or coating. After the twisting incident, the disadvantageous elongation can be significantly reduced by additional hot stretching.
