    • D06B23/06—Guiding means for preventing filaments, yarns or threads from sticking together

Definitions

  • the invention relates to a method for sizing filament yarn using one in turn a sizing trough, a pre-dryer with squeezer and wet field, a cylinder dryer and a winder containing sizing system, the yarn being driven by the cylinder dryer at a speed exceeding the transport speed in the squeezer Nassfeld is stretched. It also relates to an apparatus for performing the method.
  • stretching between the squeezing mechanism of the sizing trough and the downstream cylinder dryer is provided in the wet field.
  • the known use of the squeezing unit adjoining the sizing trough and the cylinder dryer as a drafting unit in the area of the wet field of a sizing system means that additional machine units for stretching a yarn sheet (in full width) are fundamentally not required.
  • the individual threads of the thread sheet to be treated have a defined temperature in the stretching area, namely the essentially constant cooling limit temperature which sets itself automatically after leaving the size bath.
  • the known method has proven itself in filament yarns made of polyamide, because these yarns can already be stretched properly at the cooling limit temperature of about 60 ° C. reached in the usual pre-dryer.
  • the degree of stretching is from 1.3 to 3.2 (in the order of magnitude) questionable. The stretching therefore means a considerable permanent lengthening of a yarn heated to the flow temperature and not only a temporary (essentially elastic) stretching (below the flow temperature).
  • the temperature increase of the yarn in the area of the pre-dryer required for drawing POY or LOY polyester yarn would lead to a disturbance in the sizing, for example to chipping Sizes lead because the size, which has dried prematurely due to the elevated temperature and especially because of the correspondingly longer heating-up time, cannot stretch when the filament yarn is stretched and therefore becomes cracked.
  • an additional heating of the yarn within the pre-dryer would require a careful temperature setting, which should be spared when one made use of the inherently constant cooling limit temperature known from DE-OS 36 02 968.
  • the invention has for its object to design the method and the device for stretching filament yarns between the size trough and the downstream final dryer so that in the area of the pre-dryer provided for the stretching one for the stretching of POY or LOY filament yarns, in particular polyester yarn and the like, to keep sufficient temperature automatically constant, to reach the cooling limit temperature practically as quickly as before in the package and at the same time premature drying of the size in the drawing area is excluded.
  • the solution according to the invention for the method mentioned at the outset is that the yarn is kept moist at approximately 100.degree. C. in the stretching area at full transport speed of the sizing plant becomes.
  • the solution according to the invention is characterized by moistening agents assigned to the wet field and subsequent to yarn drying in the region of the stretching. So if you keep the full width of the yarn hot and moist enough at the same time, even difficult to stretch yarn, such as polyester yarn, can be drawn according to the invention. It is essential to keep the yarn moist or moistened in a zone that is usually already assigned to predrying. According to the invention, the onset of the drying process is therefore delayed. However, this does not lead to an extension of the drying area as a whole, because the yarn temperature in the drawing or entry zone is increased compared to the prior art, so that the yarn dries all the faster after leaving the moist drawing zone.
  • the freshly sized yarn - in the full width of a group of threads - is kept or heated to about 100 ° C, that is to say about 90 to 100 ° C, without any appreciable drying until it has completely passed through the drawing area and to the desired extent is completely stretched.
  • the heating through the size bath may already be sufficient if the temperature is maintained over the stretching area without yarn drying, but additional heating means can preferably be provided in the squeeze or afterwards in the wet field or stretching area, whereby care should also be taken What is important is that the yarn in the drawing area is not yet - especially not superficially - drying.
  • the additional heating can take place by developing the heat in the package, that is to say by high-frequency heating, or from the outside by contact, convection or radiation heating.
  • the yarn should be kept moist in the drawing area by water vapor saturation of the ambient air.
  • saturated with water vapor In the context of the invention, air “is also understood to mean supersaturated air, so that the setting of the saturation is not critical.
  • the saturation of the air may (firstly with the exception of high-frequency heating) achieve that the yarn is still within the range for stretching coming zone at full transport speed of the sizing machine not only - as before - to be heated to the cooling limit temperature of approx.
  • the stretching zone cannot dry prematurely and can be damaged by stretching.Therefore, higher temperatures and shorter dwell times without premature overdrying of the size are inventively, if necessary by additional heating, in connection with the saturation of the air in the treatment zone or stretching zone erm allows.
  • the humidity of the ambient air may only be so high that electrical flashovers do not occur.
  • the short heating-up time plays an important role: the heating-up speed should significantly exceed the drying speed.
  • the entire course of the process of the method according to the invention when sizing filament yarns essentially comprises the following steps: the yarn is drawn off from the creel or from the slip tree and the full width of the thread sheet is sized in the size trough and brought to a temperature of about 70 to 95 ° C. If the temperature is sufficient from the size, the threads of the thread sheet are stretched in full air in saturated air after passing through the crushing machine. Otherwise the threads are additionally heated in the squeeze mechanism or shortly thereafter, except in the case of high-frequency heating the area around the heating and drawing zones being saturated with water vapor.
  • the thread sheet After leaving the wet field and thus the treatment zone of the machine intended for stretching, the thread sheet reaches a winding tree via a final dryer, for example a cylinder dryer.
  • a final dryer for example a cylinder dryer.
  • the threads can be relieved, i.e. relaxed, at around 130 to 160 ° C.
  • the stretching zone or the stretching point is closer to the exit of the thread sheet from the squeeze unit. If other heating agents are used for the yarn, the stretching point is accordingly further (in the transport direction) in the wet field.
  • additional heated rollers can also be provided behind the squeezing mechanism for contact heating.
  • a so-called stretching pin which generates a defined stretching point - immediately after the pin.
  • a temperature-controlled rod which is known in practice, can, if appropriate, be positioned behind the heating zone of the thread sheet and in front of any partial rods arranged upstream of the drying part of the machine.
  • the ambient air - except for high-frequency heating - must be saturated with water vapor.
  • the air humidity in this heating zone can be automatically kept at the desired saturation value via a control loop.
  • the control loop there may only be one on Saturation or oversaturation appealing moisture meter, a controller, a steam valve and a steam injection pipe required.
  • the invention also unexpectedly benefits in the treatment of yarns, for example made of polyamide, for the stretching of which the relatively high yarn temperature of approximately 100 ° C. per se would not be necessary.
  • yarns for example made of polyamide
  • higher speeds can be driven and higher degrees of stretching, for example substantially greater than 1.6 times, can be achieved because of the rapid heating-up time.
  • a group of threads denoted overall by 1 and consisting of individual filament yarns 2, in particular of polyester yarn, runs from a creel (not shown) over a reed 3, a first traction mechanism 4 (delivery mechanism), an inlet roller 5 and an immersion roller 6 through an a sizing trough 7 a sizing bath 8 into a squeezing mechanism 9 arranged at the exit of the sizing trough 7.
  • the crushing unit 9 is followed by a wet field 10, in which the thread family can be divided by wet partial rods 11 (except in the case of high-frequency heating, in which the threads - because of the closely spaced high-frequency electrodes - are to run in a single plane).
  • the wet field 10 is followed by a cylinder dryer, designated as a whole by 12, from which the thread sheet 1 runs through a dry field 14 through a drying field 14 onto a tree 15 (winder).
  • the family of threads is heated, preferably in an input zone 16, with the aid of an additional heater 17, in the exemplary embodiment with the aid of a radiation heater, in such a way that the yarn temperature assumes approximately 100 ° C.
  • the air is saturated with water vapor in the drawing or entry zone 16.
  • the additional heating designated 17 in the drawing can also be designed as a high-frequency or superheated steam heating.
  • the stretching or entrance zone 16 can be heated solely via the steam injection pipe 18.
  • a further additional heater 17 can also be omitted entirely if the entrance zone 16 extends over the squeeze mechanism 9 and if the squeeze mechanism 9 itself, in particular its lower roller 22 is designed as a heating means. If necessary, appropriate means for thermal heating are to be assigned to the heating roller of the squeezing unit 9.
  • the thread sheet 1 pretreated in the wet field 10 or in the entrance zone 16 runs for further heating and drying onto the cylinder dryer 12, which consists of a large number of individual cylinders 23.
  • a yarn temperature of around 120 ° C can be set there for further drying and relaxation.
  • the first traction mechanism 4 and / or the crushing mechanism 9 serve as braking mechanism for the wet field 10, which is at least formed as a stretching area in the entrance zone 16, while the cylinder dryer 12 and / or the second traction mechanism 13 provide the associated counterforce.
  • a drive 24 and the cylinder dryer 12 a drive 25 can be assigned to the squeeze mechanism 9 with the proviso that the take-off speed of the cylinder dryer 12 is set greater than the delivery speed of the squeeze mechanism 9 in accordance with the desired drawing ratio.
  • the desired stretching of the thread sheet 1 can thus be easily set by a control 26 connected between the drives 24 and 25.
  • the delivery speed of the crushing unit 9 corresponds to the relatively low speed in the sizing application, while the take-off speed of the cylinder dryer 12 is essentially equal to the winding speed on the tree 15.
  • the traction mechanisms 4 and 13 are used alone or in addition for stretching, they can also be actuated via drives 27 and 28 provided by the control 26.
  • the first traction mechanism 4 is advantageously combined with the crushing mechanism 9 in terms of drive.
  • it is favorable to couple the cylinder dryer 12 to the second train 13 in terms of drive.
