Definitions

  • the invention relates to a method and an apparatus for producing a two- or multi-component multifilament yarn, the components of which have different shrinkage behavior, wherein at least one component is irreversibly self-renewable by heat, and the components are combined to form a combination yarn, wherein the length change potential of the components after the processing to a fabric by a heat treatment is triggered.
  • Such yarns are for example by the DE 39 15 945 known. Thereafter, these composite yarns consist of at least two components, wherein the one component expands to a textile fabric during heat treatment after processing and the other component shrinks in this heat treatment. These yarns are therefore also referred to as Differentiaischrumpfgarne. Preferably, the two components are joined together by swirling.
  • This combination yarn is carried out in two separate steps: Component A is drawn from a spool as non-drawn yarn, drawn in a drafting field, then subjected to heat treatment by a non-contact heating device in a relaxed state, whereby this component A has the property of being processed Condition to spontaneously extend upon heat treatment in the equipment.
  • the component B is solidified and stabilized in a stretching process and then wound on a coil. This coil is used in a second stage as a template for the production of the combination yarn C, wherein the component B is withdrawn from a coil as a drawn yarn and combined with the leaking from the heat treatment component A. Both components A and B are connected to each other in a turbulizer by swirling.
  • JP-PS 09 25 00 36A It is known to produce a two-component multifilament yarn, wherein the two components are produced parallel to each other and combined by a swirling device with the aim to initiate the different shrinkage of the components by a heat treatment of the woven yarn and thereby obtain a voluminous, fluffy fabric.
  • One component is false twist texturized by this known method. As a result, the above-described Spulenablaufschwiermaschineen be avoided.
  • the fabric gets elastic properties and is voluminous.
  • the other component is extended by the heat treatment in the processed state. This different length behavior creates loops that give the fabric voluminous and fluffy properties.
  • a disadvantage of this known method is that shrinkage properties are lost as a result of the heating during the false twist texturing of this component. False twist texturing ruffles the filaments. Due to the production process of the extension component, the productivity is limited, because to achieve a suitable self-extension potential of this component (over 10% self-extension) 400 m / min delivery speed must not be exceeded:
  • the combination yarn By producing the combination yarn in a single continuous process, the winding and stripping of the shrink component and the associated yarn tension fluctuations are avoided. Also, the Vorverwirbeln required for the winding process, which adversely affects the connection of the two components, is eliminated. In addition, high handling and transport costs and the need for additional expensive winding tubes are saved. The yarn remnants resulting from each template and their removal on the supply bobbins are also eliminated. Property irregularities of the shrink yarn B, which are caused by intermediate storage of the coils or a false twist texturing, are avoided.
  • the stretching of the shrinkage component is carried out in parallel with the treatment of the extension component without any texturing, so that the combination yarn including its components in a single continuous Process is produced as a smooth, almost loop-free yarn. Both components can thereby be adjusted and bonded under equal yarn tension conditions, resulting in high quality and uniformity of the combination yarn.
  • Tension prior to stretching of the components has been found to be useful to balance stress variations and to achieve uniform conditions in the draw zone.
  • a retaining element is expediently provided which generates and regulates the desired thread tension.
  • the extension component passes vertically through the heater against gravity from bottom to top, because it is best a wall contact is avoided and also better and more uniform heating of the individual filaments of the component takes place in the heater.
  • Heat pretreatment prior to the actual heat treatment for shrinkage has surprisingly been found to be extremely effective for good quality and for achieving high production rates.
  • the stretched filaments are already preheated to a temperature close to the shrinkage temperature at the inlet to the heater, so that the filaments are heated with a much shorter heating distance to the required temperature above the shrinkage temperature T S.
  • the temperature gradient between heater and yarn is smaller than in the previous heating system.
  • the gradual, gradual heating causes all filaments to reach the same temperature at the same time and avoid looping, for example, by premature heater-induced shrinkage. Especially with coarser yarn components, a better and more uniform heating of all filaments takes place, which is also of great importance for the quality of the loop formation in the textile fabric.
  • the combination yarn is virtually loop-free.
  • the actual radiator can be shortened, whereby the process stabilized and the production speed can be increased.
  • the preheating is arranged immediately in front of the heater for the shrinkage, encapsulated by a housing or integrated into the heater.
  • FIG. 1 shows schematically the structure of the differential shrinkage yarn C after triggering the differential shrinkage effect, which is caused by the connection of the components A and B.
  • the combination yarn C is subjected to a heat treatment in the finished fabric, in which the differential shrinkage is triggered, that is, the component A is elongated, while the component B shrinks and therefore is stretched in the differential shrinkage yarn C.
  • the two components A and B are interconnected by the Verwirbelungsknoten K.
  • the number of nodes with which the two components A and B are connected to each other has a significant influence on the quality of the combination yarn C. It has been found that the number of knots necessary for a quality combination yarn can not be determined as a whole, but from the gamf unit of the Combination yarn C is dependent.
  • FIG. 1 shows schematically the structure of the differential shrinkage yarn C after triggering the differential shrinkage effect, which is caused by the connection of the components A and B.
  • the combination yarn C is subjected to a heat treatment in the finished fabric, in
  • the filaments of Yarn Component A upon initiation of the change in length during the heat treatment of the fabric in the equipment, form micro-loops which create a texture in the fabric and thus the hand and functional properties improve significantly.
  • the surface texture is voluminous, the fabric has a dry, soft and delicate feel.
  • a peach skin effect "peach skin", velvet character, silk character, linen, wool or cotton character sets in.
  • the starting materials are substantially the same for both components, polyester filaments are preferably used.
  • the properties for this different shrinkage or elongation receive the filaments by different treatment before the two components are brought together and joined together.
  • FIG. 2 schematically the treatment process for the component A (extension component) and component B (shrink component) is shown. Both components are placed in the form of pre-oriented filament yarn (POY) on conventional creels and removed overhead.
  • POY pre-oriented filament yarn
  • the multifilament yarn is drawn for producing the component A from a coil 1A through an eyelet 15 and fed to a draw roller 2, which forms a drafting field with the following draw roller 3.
  • the stretch roller 2 is heated with a surface temperature which is chosen so that the filaments above it undergo heating to a temperature in the range of the so-called. Glass transition temperature T G , so that after the Stretching a maximum tensile strength according to ISO 2062 of the yarn of 25% to 40% is achieved.
  • the temperature of the heated draw roll 2 is chosen so that the drawn yarn A has the shrinkage capacity required for the subsequent process. The degree of crystallization of the drawn filaments is thus higher than that of the master material.
  • the above Shrinkage temperature T S is ( Figure 8 ). This takes place between the rolls 3 and 4, the roll 3 supplying the filaments with a lore (degree of diffusion ⁇ 1), which corresponds almost to the shrinkage capacity of the filaments of the extension component A. From the roll 3, the yarn A is thus supplied to the heater 7 much faster than it is withdrawn by the roller 4, so that the filaments under the heating effect of the heater 7 can shrink by about 30% to 55%. As a result of this shrinkage treatment, component A acquires the property of spontaneously and irreversibly extending later in a heat treatment in the processed state.
  • the filaments must be able to move freely to shrink unhindered. It is therefore a heater 7 is used in which the threads have no mechanical contact during their passage. Convection heaters are preferably used here, in which the filaments are heated by air or steam or the like.
  • this heater 7 is arranged vertically to prevent sagging of the relaxed filaments. Furthermore, it has proved to be advantageous to guide the component A from the bottom up against gravity by the heater 7, so that the weight of the thread supports the required shrinkage during the reduction of the thread speed.
  • the chimney effect has a favorable effect in this direction of passage, since not the hottest temperature acts immediately on the thread. By the incoming air, the heating power comes gradually to effect. The filaments are heated more evenly. It has surprisingly been found that the heating of the filaments is not shock-like, but must be gradual, to obtain a loop-free, smooth yarn that can be further processed trouble-free even at high production speeds.
  • the extension component A is combined with the shrink component B.
  • the shrink component B has now also undergone its treatment, which is necessary to shrink in the processed state during heat treatment.
  • the master material 1B is withdrawn overhead through a suture loop 16 and fed to the draw roll 5, which forms a drafting field with the subsequent draw roll 6, in which the filaments are subjected to stretching so that they have a maximum tensile elongation of 25% to 40% after drawing % and a wet shrinkage of 1% to 70%.
  • the draw roller 5 is heated to heat the filaments for the drawing operation. Following this stretching then the merge with the component A.
  • the thread tension formed by the stretching process in the component B of the thread tension of the component A is adjusted so that a uniform turbulence of the two components in the turbulator 8 is guaranteed.
  • the turbulizer 8 leave the now connected by the swirling components A and B as a combination yarn C, which is guided by a arranged in front of the winder 9 Fadenzu Fighting 91 and wound up into a coil.
  • the combination yarn C produced by this one-step process is characterized by high quality and uniformity.
  • both components A and B can be brought together under completely identical conditions at the end, which is essential for the subsequent connection in the turbulizer. Both components are smooth. Due to the gradual warming of the component A in the heater 7, despite the high lore for the shrinking loop formation is avoided, which occurs in the usual shock heating. Neither an additional winding process with required winding tubes, nor a corresponding logistics and transport is required to bring the two components together.
  • the stress on the filaments and the risk of filament breaks are avoided without additional measures, such as a so-called Vorverwirbelung would be required for the winding of the component B. This Vorverwirbelung, which is necessary to avoid disturbances when winding up and down the filaments on a coil, prevents a uniform and good connection of the components A and B and also leads to looping.
  • FIG. 3 another embodiment of the single stage process is shown.
  • the process has been optimized by some additional equipment, so that even higher production speeds can be achieved while maintaining and even increasing the quality.
  • supply rolls 1A and 1B with preoriented polyester multifilament yarns (PET-POY), which are pulled off at the top by thread eyelets 15 and 16, respectively, are provided as the original material.
  • PET-POY preoriented polyester multifilament yarns
  • a delivery mechanism 10 is arranged, which exerts a certain retention function, so that a tension of the filaments to equalize the fluctuating in the withdrawal of the coil voltage of the drawing in the draw field between the rollers 2 and 3 thread.
  • In the simplest version can be used as a retaining element and a thread brake.
  • a contact heater 14 is also provided in the drafting field for heating the filaments during drawing to obtain the desired maximum tensile strength and shrinkage values.
  • the filament yarn now does not run directly into the heater 7, but only through a roller 71, which serves as a preheater and is located immediately in front of the heater 7, to avoid an intermediate cooling of the yarn largely.
  • the filaments are relaxed after stretching before undergoing the heat pretreatment. By this relaxation, which can be done by a slight lore, the shrinkage process is improved, and the shrinkage potential of the drawn yarn A can be better utilized.
  • This heat pretreatment has proved to be extremely important and expedient, especially when component A is coarser. Namely, there arises the problem of uniformly heating all filaments in the heater 7. When the filaments are not sure to be at the same temperature above the shrinkage temperature T S at the same time, they will shrink differently and undesirable loops will form, which will be detrimental to the processing of the combination yarns C. For a good processing behavior, the yarns C otherwise z. B. for the weaving additionally finished or provided with rotation. The production cost of the yarn would almost double by such an additional measure.
  • the filaments are heated to a temperature just below the shrinkage temperature T S , so that only a small temperature difference must be heated in the heater 7 for the shrinking process, namely from dense below the shrinkage temperature T S to above the shrinkage temperature T S to the temperature required for the elongation properties T L ( Figure 8 ).
  • the heater 7 can thus not only be considerably shorter, but it can be driven with such a two-stage heating and much higher speeds.
  • this preheater 71 is arranged as close as possible in front of the heater 7, optionally also integrated into this by means of a screening hood 72, or both heaters 7 and 71 are combined to form a two- or multi-stage heater.
  • a preferably designed as a heated roller contact heater is used, the heat transfer is much more efficient than a convection heater.
  • the extension component A is withdrawn through the pair of rollers 4 and thereby merged with the shrink component B.
  • the heater 7 may be carried out in one or more stages to ensure uniform heating of all filaments.
  • a stage heater is shown in detail, in which also the preheater 71 is included. It begins with the preheater 71, which gives the filaments a temperature just below the shrinkage temperature T S , where they are relatively insensitive. At this temperature, the filaments enter the heater 7. By the housing 72 cooling on transition into the heater 7 is prevented.
  • the heater 7 is divided into three heating zones, which are traversed by the filaments of component A. In the first heating zone, a heating element H1 is installed, which acts on the filaments at a temperature T H1 ( Fig. 9 ).
  • the temperature of the filaments rises slowly, so that all filaments can follow this increase in temperature despite high production speed.
  • a heating element H2 with the temperature T H2 acts, and there is a further heating of the filaments. Only at the end of the third zone with the temperature T H3 the filaments reach the temperature required for the desired elongation properties T L , with which the component A leaves the heater.
  • Fig. 8 schematically shows the temperature profile of the filaments during their heating in the heater 7.
  • the dashed line shows schematically the temperature increase in the filaments when using a single, over the length of the heater 7 evenly with the temperature T H acting heating element.
  • T H acting heating element the temperature of the filaments.
  • a gradual heating can be achieved here as well, if the filaments go through the heater 7 from bottom to top. Due to the resulting air flow (chimney effect), the air in the heater 7 is warmer at the top than below.
  • the time can be reduced at which the filaments reach a temperature above the shrinking temperature T S have.
  • the temperature of the filaments is brought back to a temperature lower than T S.
  • the shrinkage component B has since been treated in parallel to obtain the desired shrinkage properties.
