Definitions
- the invention relates to a method for texturing a thermoplastic yarn according to the preamble of the independent claim.
- thermoplastic Filament is drawn from a wrap overhead and is delivered to one by a supplier Heating box fed.
- the thread runs through a heating box, followed by one False wire aggregate to a delivery plant.
- the twist generated by the false wire aggregate causes a spiral-shaped deformation of the Filaments, which are then fixed by cooling, then attached to the False wire aggregate, textured, passes draillically over one Thread sensor to the take-off delivery plant and then via an oil device to the Sputer where the textured thread is wound up.
- the disadvantage of this process is that it has a very long processing distance needs what texturing device with a very large length and complex Thread run caused. Accordingly, the processing speed is limited. Among other things, it depends on the speed and quality of the Heat input in the thread depending on the heating box. So that the thread is good and can be heated evenly, it must be inside the heating box for a long time. This is achieved through the large length of the heating box.
- the processing speed should be significantly increased.
- An advantage of the invention is that the new method makes it possible to be able to build a texturing device which is considerably less long and thus requires significantly less space.
- Another advantage is that better on the specific properties of the Thread can be influenced.
- Raw yarn to be textured e.g. a thermoplastic filament, according to conventional type brought to a feed station 1 on coils 11, 11 '. Of the The raw yarn, usually unwound from the top, enters the feed station directly Texturing module 2. After leaving the texturing module, the finished textured one Yarn fed to a winder station. where it is wound up. Between the Texturing module 2 and the winder station 4, an oiler 3 can be arranged.
- the texturing module has neither a heating duct nor a purely supply unit. This necessary functions are taken over by elements with other functions.
- the raw yarn is first in the texturing module 2 at an input speed Retracted and heated to a preheating temperature T1. Then it will be Pre-heated raw yarn pre-stretched by a certain amount and then to the full Textured temperature T2 heated.
- the fully warmed yarn now gets the texture in a cooled texturing section between a swirl stop and a False twist organ.
- the yarn is opened the fixing temperature T3 cooled.
- the now textured yarn arrives at a Elasticity correction station, which the yarn to a selectable correction temperature T4 brings.
- the textured yarn then leaves the texturing module 2. It is over the oiler 3 fed to the winding station 4.
- the decisive factor in this process is the two-stage heating with in between pre-stretching. This ensures optimal heating of the raw yarn in its entire cross-section and with all its filaments to the necessary Texturing temperature T2. This does not change the texture during heating introduced, but in a yarn. which already has the necessary temperature T2 in its entire material.
- the fixation of the Texture in the yarn can be made by the yarn in this texturing area is already fixed to the fixing temperature T3 by active cooling.
- the entry of the Texture happens from the false wire organ backwards to the twist stop and thus mainly near the swirl stop.
- the cooling takes place Fixation of the texture immediately without the material softened by the heat mechanically loaded.
- a single texturing device or texturing module 2 can now, for example be constructed as follows. This arrives at the entrance to the texturing module 2 Raw yarn on a first heating godet 21, which with a peripheral speed V1 running. This is wrapped around several times. The raw yarn is on the surface of the first heating godet 21 flattened and heated to the preheating temperature. By the flat cross section when resting on the roll of the first heating godet 21 receives this Raw yarn now preheat temperature T1. In the case of texturing polypropylene However, the first heating godet 21 is not heated, which means that it is sufficient that it is about Has room temperature. These preheating temperatures T1 now enable the Advance or pre-stretching at the transition to a second heating gate 22, which runs with a larger peripheral speed V2.
- the second heating godet 22 is wrapped several times so that the material of the yarn is completely on the Texturing temperature T2 is heated.
- the yarn passes through a twist stop 23 through the texturing area 24, which is provided with a cooling section.
- the Cooling section near the false wire unit 25 has a lower temperature than at after its infeed at the twist stop 23.
- the cooling section brings the yarn at the end of the Bringing the texture onto the yarn at the fixing temperature T3, whereby the texture in the Yarn is fixed.
- friction swirlers are particularly suitable with a plurality of friction discs. Behind the false wire assembly 25 that is now textured and twist-free yarn withdrawn from a third heating godet 26 and on transported. After the third heating godet 26, further process zones can be used to be ordered.
- another heater can be used for subsequent fixing a subsequent supplier.
- Active cooling during texturing section 24 is just as crucial.
- the cooling system must also have sufficient power and be transferred to the yarn can, with special consideration that the yarn during the full production speed while texturing to the necessary Temperatures must be cooled.
- air cooling suitable for this, but also liquid cooling with and without direct contact with the yarn.
- Further special possibilities are also provided so that in the heated yarn existing heat can also be dissipated quickly enough from the cooling section.
- a cooling channel with water, oil, refrigerant or liquid Sodium or saline medium, a salt or salt mixture with suitable Melting temperature filled or rinsed.
- a coolant that lies between evaporated about 50 ° and 300 °.
- the latent heat or the resulting one helps Evaporative chill significantly with extracting enough heat from the yarn to make it cool down to the appropriate temperature within the texturing section 44.
- the Cooling line can be with a cooling rail, a cooling channel, a cooling pipe or Equipped since, the length of which is adjustable for optimization. It's clear, that the cooling rail must contain material with good thermal conductivity so that the heat dissipated from the yarn can also be transferred away. It is also said to be little Generate friction and at the same time be chemically stable.
- Spray unit 241 arranged.
- Water is sprayed onto the yarn in tiny droplets. Cool those little droplets remove the yarn by removing heat from the yarn as it evaporates. So none unwanted residual moisture remaining in the yarn can end up being active Cooling section, ie shortly before the false wire member 25, a vacuum or suction chamber be arranged. Evaporated or vacuumed by the vacuum. the last one still evaporates Proportion of water sprayed on.
- Such cooling with direct yarn contact and a medium that can extract a lot of latent heat is of course special effectively.
- the Texturing section comprises a cooling rail, which is provided with a number of air nozzles 243 is provided. Cooling air, especially pre-cooled air, is fed in via supply lines 2431 blown the air nozzles 243 and then meets the yarn F, which in the direction the arrow is moved through the cooling rail.
- An arrangement is particularly suitable an air nozzle 2432 which is inclined at an angle to the running direction of the yarn is against the direction of travel, so that the air from the colder part in the direction is blown to warmer.
- Blowing nozzles 234 with suction devices can also be used be combined so that the air flow and thus the efficiency of cooling the Yarn is optimized.
- FIG. 3 also shows the cooling rail in a particularly suitable form. there it is open on the side. This enables the device according to the invention To design texturing processes with an automatic loading device. On A robotic arm can automatically use a suction gun to filament a filament to be textured Thread. All elements of the texturing device are freely accessible from one side, so that the robot arm can automatically go through all stations.
- the type of yarn to be textured can be optimally regulated.
- a sensor is used for this Monitoring the thread tension in the area of the texturing section 24 and whose measured values are used to regulate the thread tension.
- Regulating the thread tension in the texturing area can be bationing, d. H. Swinging of the yarn is at least partially suppressed or prevented.
- the cooling channel can have a narrow free cross-section or the yarn can be pulled over a cooling pipe.
- a texturing machine thus becomes a plurality of such texturing devices exist, which can be operated individually individually. This increases the flexibility of texturing and the quality can be increased.
- the multi-stage and individually controllable preheating and pre-stretching combined with The active cooling in the texturing section results in a significantly small construction for texturing machines than is possible today.
