Definitions
- the invention relates to a method for air texturing of threads made of glass fibers, in which the threads are fed to a first delivery unit, from there to a texturing nozzle and then to a second delivery unit. It also relates to a device for carrying out such a method with a first and a second delivery mechanism and a texturing nozzle arranged between the two.
- a disadvantage of this method is that twisting as a separate work process before being fed to the texturing nozzle represents a considerable cost.
- Another disadvantage is that the twisting of brittle material requires the use of aids. So it is known, for example, to apply so-called textile sizing to glass fiber material in order to enable this material to be twisted at all.
- a disadvantage of this procedure is not only the additional cost, but also the fact that the textile size used is disadvantageous when the yarn is used later, for example by making it more difficult to embed it in a matrix.
- the blowing units causing a twist are therefore in front of the actual texturing zone and are intended to confuse the filaments of the threads and to break any connections between the filaments.
- the threads are loosened before entering the actual texturing device. Accordingly, there is a fear that when the threads subsequently run into a texturing nozzle, the flow into this nozzle will be disturbed by the filaments of the threads puffing up, clogging the nozzle and causing operational interruptions.
- the object of the present invention is now to provide a method of the type mentioned at the outset, with which the threads to be textured can be reliably fed to the texturing nozzle and textured uniformly there with considerably less effort.
- the threads should only be subjected to a slight load, so that the use of auxiliaries is also required for critical starting materials can at least largely be dispensed with.
- the object is achieved according to the invention in a method of the type mentioned at the outset in that the threads are fed separately or in a fan to the first delivery mechanism and in that the threads are given a false twist at least for the area between the inlet of the texturing nozzle and its outlet, which is the whole the threads fed into a unit.
- the method according to the invention can also be carried out in such a way that the threads between the texturing nozzle and the second delivery mechanism are guided via a false twister which gives the threads rotation in the region between the first delivery mechanism and the false twister.
- the method according to the invention can also be carried out in such a way that the yarn in the area of the texturing nozzle is given a rotation of up to 150 T / m.
- the method according to the invention can also be carried out in such a way that the yarn in the area of the texturing nozzle has a Z- or an S-turn is given. This enables a special effect to be achieved on the textured yarn.
- the method according to the invention can also be carried out in such a way that twisted and / or untwisted threads are fed to the first delivery mechanism.
- the textured yarns to be produced can have very special properties, in particular with regard to strength, elongation and volume.
- a device provided for carrying out the method according to the invention is characterized according to the invention in that a false twister is arranged between the texturing nozzle and the second delivery mechanism, the deflection body of which is a twist pin rotatably mounted about its axis, the axis of which is inclined to the direction of transport of the threads and the diameter of which is larger than 4 mm.
- the rotatable bearing of the twist pin avoids friction and thus stress on the individual threads when passing through the false twister.
- the threads can be guided in such a way that contact between the turns is avoided when passing through the swirl pin.
- the inclination of the twist pin with respect to the direction of transport of the threads prevents contact between the turns of the yarn when passing through the twist pin and thus also protects the material.
- a diameter of more than 4 mm also enables the processing of relatively brittle materials.
- the device according to the invention can be designed such that the false twister can be adjusted in its distance from the texturing nozzle.
- three unthreaded threads 1, 2, 3 are fed as multifilaments to a first delivery mechanism 4 of a conventional type.
- the threads 1, 2, 3 reach the feed mechanism 4 via an inlet 5 into a texturing nozzle 6, from which they emerge at the outlet 7.
- the threads 1, 2, 3 are then guided via a false twister 9 to a second delivery unit 10 and are drawn off from there in the direction of the arrow 11.
- the texturing nozzle 6 is of a known type. In it the threads 1, 2, 3 are blown up by blowing in compressed air in a manner known per se.
- the false twister 9 is provided with a drive, not shown, which rotates the false twister 9 about an axis running in the transport direction. It has a ring 12, in which a swirl pin 13 is held, which is freely rotatable according to arrow 14 about an axis running diametrically to the ring 12. The axis of the twist pin 13 does not run transversely to the direction of transport of the threads, but inclined to it.
- the threads form a loop on the swirl pin 13, the beginning and end of which do not touch due to the inclination of the swirl pin 13.
- the swirl pin 13 rotates according to the speed of transport of the threads.
- the relative speed between the outer surface of the swirl pin 13 on the one hand and the threads on the other hand is zero.
- the false twist sensor 9 can be adjusted in its distance from the texturing nozzle 6 in order to be able to adapt the device to the particular circumstances with regard to material and yarn titer.
- the take-off speeds of the delivery mechanisms 4, 10 are coordinated with one another in a known manner in order to take account of the shortening that occurs as a result of the bulging of the material.
- the threads 1, 2, 3 are fed to the false twister 9 via the first delivery mechanism 4 and the texturing nozzle 6.
- the threads 1, 2, 3 receive a rotation which is preferably below 100 T / m.
- the threads 1, 2, 3 fed individually to the first delivery mechanism 4 are combined to form a closed unit and, as such, are drawn into the texturing nozzle 6 at the inlet 5.
- the number of twists per unit length given to the threads is determined depending on the properties of the threads selected. The condition of the material must also be taken into account and it must be ensured that the number of rotations does not overload any of the materials used.
- the textured yarn leaving the outlet 7 still has the given twists. Due to the known false-wire effect, it has no more rotation after passing the false twister 9, which results in a further bulging.
- Bulkable threads can be processed using the method according to the invention and the device provided for this purpose.
- the processing of relatively brittle threads e.g. those made of glass fibers, possible because the method and device ensure gentle handling of these threads.
