Definitions
- the invention relates to a process for the production of technical filament yarns by intermingling a polyester multifilament at elevated temperature, under a thread tension of less than 140 cN, in an interlaced air nozzle, consisting of a nozzle body with a perforated plate and a baffle plate, and a device for carrying it out of the process and a technical filament yarn.
- Multifilament yarns are intermingled during the spinning process in order to maintain interweaving of the individual filament fibrils and to avoid thread spreading during further processing.
- the interlacing takes place selectively, enables the individual filaments in the fibril bandage to be held together better and the yarn to be processed further.
- Methods for interlacing the multifilament yarns are known, the knot formation taking place in a swirl channel or between two plates by means of an air jet.
- the number of nodes can be controlled both via the pressure and the speed of the swirling air.
- oligomers are always formed, which can be deposited on the surface of the multifilament yarn by blowing on the cold baffle plate of the intermingling nozzles. These hard, often crust-like deposits can cause blockages in the air supply and in the drainage channels and damage to the fibrils, as well as inadequate, unstable and irregularly arranged nodes.
- Winding thread tensile strength of less than 100 cN are marked, in a total titer range of 500 to 2000 dtex tend to form particularly strong
- 0 148 402 describes a commercially available, open
- the nozzle can be mechanically and chemically cleaned in a complex process.
- hot intermingling air was used for the production of such multifilament yarns.
- This so-called hot air swirling becomes cold Compressed air heated up to approximately 290 ° C by an air heater installed in the compressed air system. Improvements have been achieved which, however, are unsatisfactory, particularly because of the irregular arrangement of the nodes and the high energy consumption. Hot air swirling has the further disadvantage that a complex control system questions the economic viability of such a method.
- the object of the invention is to provide a simplified method which enables a better knot distribution and allows an extended nozzle service life.
- Another object is to provide a swirling device that reduces the energy consumption of the process during swirling.
- Yet another task is to provide an industrial yarn that is more suitable for weaving use.
- Weaving is primarily used for fabrics for tents, piaches, membrane structures, awnings, projection walls and geotextiles, which are usually coated.
- the object is achieved according to the invention in that the heat is transferred directly to the polyester multifilament and the air via the nozzle body to a highly thermally conductive metal block which is connected directly to the baffle plate and in which a bore is provided for receiving a radiator. This will improve scattering and node distribution, as well as an enormous energy saving of 85%.
- the swirl nozzle as a cold point in the spinning process is eliminated.
- baffle plate it is expedient to heat the baffle plate to a constant temperature between 150 and 180 ° C., in particular 150 ° to 170 ° C., preferably 160 ° C.
- a temperature below 150 ° C has the disadvantage of increasing deposits; at a temperature above 180 ° C the swirl properties do not improve any further.
- the number of knots per meter is either too low or too high.
- the device for performing the method consists of a swirl nozzle with a nozzle body, a perforated plate and an impact plate.
- the baffle plate is expediently connected directly and flush to a highly thermally conductive metal block, for example made of aluminum, in which a bore is provided for receiving a radiator. Electrical resistance heaters or any other space-saving heating are suitable as radiators.
- the direct contact between the baffle plate and the metal block is essential.
- a polyester filament yarn produced by the method according to the invention with a winding tension of less than 140 cN, in particular less than 100 cN and with a total titer of 500 - 2000 dtex, has a strength of at least 70 cN / tex and an elongation at break of less than 24%, an increased knot resistance of more than 80% and a distance between 2 knots of more than 4.0 cm.
- the polyester filament is ideally suited for the production of coated fabrics for industrial purposes.
- Fig. 1 shows a swirl nozzle according to the invention in side view.
- a nozzle body is designated by the reference numeral 1.
- the nozzle body 1 is connected to a baffle plate 3 via a perforated plate 2.
- Nozzle body 1 is a compressed air line 4 via a
- Thread guide 6 'guaranteed On the baffle plate 3, a metal body 8 is provided flush with
- the metal body 8 is provided with a bore 7 for receiving a radiator.
- the functioning of the device is explained in the exemplary embodiments.
- the nozzle described in FIG. 1 was pressurized in a known manner via the compressed air line 4 with commercially available, cold compressed air of 1.8 bar.
- a constant temperature level of 160 ° C at the baffle plate 3 could be maintained for 80 hours with the radiator with a heating power of 50W / 50V.
- Table 1 shows the results achieved in comparison with the known hot air swirling.
- the table shows that after an operating time of 80 hours, a swirl of 12.1 knots / m (target value: 12.0 ⁇ 1.5) with a scatter of 0.36 and a swirl stability of 87.1% become.
- the swirl nozzle according to the invention was used for 96 hours with a baffle plate temperature of 160 ° C.
- the standard air pressure of 2.8 bar corresponds to that of hot air swirling.
- Table 2 shows the results achieved in comparison with the known hot air swirling.
- Thread measured according to the needle stitch method with a dynamic load of 0.5 cN / tex and 1000 load changes per minute .
- the hot nozzle swirl brings an equally good swirl value, good knot resistance and a significantly better knot distribution.
- the smallest distance between 2 knots increased by at least about 15% from 3.4 to 4 cm.
- the serimetric properties and thread cleanliness remained unchanged.
- the method according to the invention is particularly suitable for producing high-strength industrial yarn for fabrics for tents, piaches and geotextiles, which are generally coated.
