Definitions
- the invention relates to technical fabrics, in particular to improved paper machine fabrics based on a thread of synthetic polymers and a
- the process for producing paper is basically known to the person skilled in the art.
- Water is applied to a fabric of metallic or synthetic wires and the liquid is removed by gravity and / or suction until a self-supporting wet paper "sheet" is formed.
- the still very moist paper sheet which is sensitive to mechanical processing, is placed on a so-called paper machine felt (PMF) and passed together with it through rollers pressing against each other. At the point of contact of the rollers, the "gap", the paper sheet is pressed together with the paper machine felt and further water is pressed out of the paper sheet. Finally, the rest of the liquid still present in the subsequent drying section is then removed from the further solidified sheet
- PMF paper machine felt
- the paper machine felt used in the press section to squeeze out the liquid generally consists of polyamide fibers and polyamide monofilaments, which are brought together according to known processes to “felt” the desired constructions and are usually needled together.
- Typical felts consist of a base fabric Made of polyamide monofilaments, which are connected on one or both sides with a needle fleece made of polyamide staple fibers.
- the base fabric is a single-ply or multi-ply fabric made of polyamide monofilaments, the monofilaments being processed into fabrics by methods known in principle.
- the monofilaments themselves usually have a diameter of 0.08 mm to 0.60 mm, in rare cases up to 1, 20 mm.
- threads consist of three to 40 monofilaments and are produced in two stages.
- a so-called pre-twist is produced on conventional twisting machines, in which two to eight monofilaments, preferably two to three monofilaments, with 150 to 400 revolutions per meter in one direction, e.g. B.
- a pre-twist is produced from the pre-twist in a second processing step, in that two to five pre-twists are twisted (twisted) in the opposite direction of rotation - in the example mentioned above in the Z direction.
- the number of twists of the twisting is below the twists of the previous twig
- threading (in the Z direction) 150 to 250 revolutions per meter.
- the twisted thread which is produced in two stages, is calmed down and can therefore be processed without major problems.
- some problems in the further processing into fabrics cannot be solved or completely eliminated with the threads mentioned and require complex further processing steps.
- the twists are heat-set according to the invention after the pre-twisting process in a continuously operating heat-setting device at temperatures between 70 ° C. and 240 ° C. under defined tension and the threads treated in this way are further processed into technical fabric, in particular for paper machine felts.
- the invention relates to a method for producing a thread for technical fabrics, in particular for paper machine clothing and fabrics, characterized in that a thread made of monofilaments made of synthetic polymer, in particular of polyamide, is rotated in one direction of rotation (S or Z direction) a diameter of the monofilament from 0.06 mm to 0.60 mm, preferably from 0.08 mm to 0.25 mm, is heat-set at a temperature of 70 ° C. to 240 ° C. to calm the swirl.
- S or Z direction a diameter of the monofilament from 0.06 mm to 0.60 mm, preferably from 0.08 mm to 0.25 mm
- the monofilaments consist in particular of the class of polyamides, particularly preferably selected from the series polyamide 6, polyamide 6.6, polyamide 6.9, polyamide 6.10, polyamide 6.12, polyamide 11, polyamide 12 or mixtures of the polyamides or copolyamides mentioned from the starting monomers of these polyamides.
- the heat transfer takes place during the heat setting on the monofilaments by a heating medium, in particular hot air, water or water vapor or by the action of heat radiation.
- a heating medium in particular hot air, water or water vapor or by the action of heat radiation.
- the heat setting can be carried out either stationary or continuously.
- the heat-setting takes place in particular continuously between two delivery arrangements with at least two rollers each with a different rotational speed of the delivery arrangements, the rotational speed of the first roller pair being in particular higher than that of the second roller pair and the delivery to the first delivery arrangement of the heat-setting under slight thread tension, in particular from 50 to 200 g is done.
- the heat setting is preferably carried out over a period of 0.5 seconds to 20 minutes, preferably from 1 second to 15 minutes.
- the invention also relates to yarn made from monofilaments of synthetic polymers, obtainable from the process according to the invention.
- Another object of the invention is technical fabric, in particular paper machine fabric for press felts, containing the threads according to the invention.
- Either air or water, liquid or in the form of steam serves as the transport medium for the heat energy for heat setting.
- the pressure of the surrounding medium can be from 1 to 5 bar, preferably 1 to 3 bar.
- the effect of heat is related to the absolute temperature of the medium and can be from 2 seconds to 20 minutes.
- FIG. 1 The basic process flow is shown in FIG. 1.
- the method according to the invention has a number of advantages over the previously known methods.
- the threads After heat setting, the threads have a precisely defined shrinkage that can be precisely adjusted to the requirements of further processing. Thereby uniform technical fabrics can be produced that no longer require intensive post-processing and whose reject rate is lower.
- the technical fabrics obtainable from the twists according to the invention have a more controllable width and length because the shrinkage differences of the
- Threads are practically eliminated and the processor does not have to overcompensate for the fabric irregularities by a higher heat setting temperature.
- the technical fabrics obtainable from the threads of the invention are more flexible due to the heat setting of the threads before weaving, i.e. softer and easier to process in the subsequent processing stages, especially by papermakers when they are introduced into the paper machine.
- the fabrics have a more uniform surface, which reduces the marking of the paper machine felt in the paper.
- FIG. 1 shows a process diagram for representing the process according to the invention
- FIG. 1 shows a process diagram for representing the process according to the invention
- the thread thus produced is calmed in a suitable, continuously working heat-setting device.
- the thread 5 is passed under a slight thread tension (100 to 120 g) from the thread spool 1 via a delivery unit 2 consisting of five rollers (delivery unit 2) through an aqueous heat-setting bath 3 with a length of 3 m and a temperature of 96 ° C. and from a take-off unit with another five rollers (delivery unit 6), taken off via a suction device (not shown) to remove the water present on the twine and wound up on a winding unit 4 on disc spools.
- the take-off speed of the delivery unit 2 is 50 m / min, that of the delivery unit 6 is 45.5 m / min.
- the heat-set thread has no twist when relaxed.

After marking the length, the samples were placed without tension in boiling water at atmospheric pressure for five minutes and again for 48 hours at 20 ° C. and 65% rel. Humid air-conditioned. The shortening of the thread is 3.0%, based on the original length of the thread that has already been fixed.
- the resulting shrinkage can be adjusted to any value desired for further processing to the technical fabric from 0 to 15% by the level of the heating air's fixing temperature, the length of time in the heat setting medium and by the relative speed of the take-off unit compared to the supply unit when fixing.
