Definitions
- the invention relates to a device for spinning man-made fibers according to the preamble of claim 1.
- This spinning device is known from DE-A 19 14 556.
- it has the advantage that the fiber bundle, which consists of a large number of individual filaments, is subjected to an air flow over its entire circumference.
- uneven thread properties arise. This unevenness may be due to the fact that the chemical fibers running at very high speed and at the same time very high thread tension only become uniform over their length if the running smoothness is very great.
- air turbulence in the spinning chamber which leads to pressure fluctuations on the outer jacket of the cooling tube, also results in an uneveness of the filaments or threads produced. This is especially true when the spinning device is operated at a very high winding speed. Because this creates very strong air movements.
- EP 0 117 215 B1 and EP 0 118 375 B1 disclose spinning devices whose winding machine, with which the chemical fibers are wound into bobbins, are arranged at a short distance below the spinneret. This is made possible by the fact that Chemical fibers at a very high speed of more than 6000 m / min. be wound up. This results in a very intensive cooling of the threads, so that a very short cooling zone of about 2 m is sufficient, while cooling zones of more than 4 m are required in conventional spinning systems. As a result of the high speed, there is very strong air friction, so that the chemical fibers are wound up more or less completely stretched.
- the man-made fibers can be drawn off from the spinneret directly by pulling the take-up spool.
- a delivery mechanism can also be provided between the spinneret and the winding device, in particular a slip conveyor mechanism according to DE-A 41 35 350 (1-1951).
- porous or perforated cooling tubes have hitherto been used, which are the subject of DE-A 34 06 347 (Bag. 1326) and DE-A 34 24 253.8-26 (Bag. 1419) ) are. Reference can also be made to DE-A 37 41 135 (Bag. 1558) and DE-A 39 23 067 (Bag. 1648).
- the cooling air is supplied in a defined manner by a blower, so that the air flow supplied to the cooling pipe can be largely homogenized in terms of space and time.
- a disadvantage of this latter blowing technology is that complex apparatus and procedural measures are required in order to ensure a temporal and very uniform length, i.e. to achieve swirl-free air flow on the chemical fiber bundle.
- the object of the invention is to design the known spinning device so that a simple the chemical fibers run smoothly and chemical fibers with great longitudinal uniformity are produced.
- the radial air flow is generated in that the chemical fibers running at high speed create a negative pressure in the tube.
- the invention enables good flow and cooling conditions to be set with little effort.
- the measure according to claim 3 is also used. These measures not only prevent the air vortices entrained by the fiber bundle from flowing back into the area of the cooling tube and leading to an uneven application of atmospheric air to the cooling tube. It will rather, it also prevents pressure fluctuations and pressure waves from propagating into the intake area of the cooling tube.
- the proposed air box is connected to the atmosphere.
- the air box is designed so that there is essentially atmospheric pressure or vacuum.
- defined openings can be provided at one or more points.
- An intermediate wall can be used to prevent the inflowing air from acting directly on the outer circumference of the cooling tube.
- the air box can be penetrated by a plurality of cooling tubes, each of which is assigned to a spinneret. This makes it possible to produce the same cooling conditions for the majority of the cooling tubes and in this way to one another to produce the same and uniform chemical fibers.
- the air box is not connected to a blower with which an air pressure, albeit low, is generated in the air box. Rather, the fact that a pressure gradient arises which is directed from the spinning chamber into the air box and from there into the cooling tube is used for the air supply.
- Measures can be provided to direct the air currents drawn into the cooling tube from the outside in. This can be done in particular by guide rings which are attached to the inner wall of the cooling tube in one or more normal planes and are directed essentially radially inwards. Of course, these guide rings leave a passage opening for the chemical fiber bundle in the center of the cooling tube.
- a vacuum is also created on the underside of the guide rings, which leads to pre-suction of the outside air.
- the filaments are initially in the open state, ie. H. in front of the thread guide 7, are passed through a cooling tube 5.
- the cooling tube 5 connects directly to the spinneret 3.
- the cooling tube 5 is porous. It has a length of 0.5 to 2.0 meters.
- a shielding plate 6 is applied at the outlet end of the cooling tube 5.
- the shielding plate 6 has a passage opening for the filament bundle, the width of which is equal to or less than the inside width of the cooling tube 5.
- the porosity of the cooling tube 5 increases in the direction of the thread.
- the porosity is essentially proportional, but at least depends on the thread running speed.
- the porosity can also be adapted to the temperature profile that the filaments have over their length. In both of the cases described, the porosity increases in the thread running direction, ie the air permeability increases.
- the embodiment of Figure 1 has the peculiarity that a plurality of baffle plates 17 are arranged in the cooling tube.
- the baffle plates 17 are annular plates. These annular sheets are fastened with their outer circumference to the cooling tube 5 and point with their inner edge in the thread running direction, that is to say they are inclined downwards. These baffle plates 17 guide the sucked-in air currents downward, but also cause a negative pressure to develop beneath them, so that this results in a suction effect.
- the thread speed is more than 6000 m / min.
