Definitions

  • the present invention relates to a method for producing a fancy yarn on open-end spinning devices, in which ribbon-like basic fiber material is dissolved into individual fibers and fed to an open-end spinning element in an air stream, and an apparatus for carrying out this method.
  • the effect fiber material is dissolved by means of a drafting system and the pieces of effect material thus produced are thrown against a screen by means of an air stream for the purpose of further conveyance to the nip between a pair of rotating friction rollers, where they engage combine the base material and twist it into a thread.
  • the frequency length and thickness of the effect material pieces in the effect yarn is determined by means of a program that influences the drive of the drawing rollers for the production of the effect material pieces.
  • Such a drive, controlled by the program is complex.
  • only those effects can be created that are entered into the program have been. Since such a program can only have a limited length of variation, it cannot be avoided that the variations are repeated even with complex programming. For fancy yarns, however, it is desirable that as few repetitions of the variations as possible occur or only after long periods.
  • the object of the invention is to provide a method and a device for producing knitting yarn with which the greatest possible random distribution of the effects is achieved in a simple manner.
  • the effect fiber material is fed to an air stream at a constant speed in the form of a closed, ie uninterrupted, fiber ribbon and in that fiber bundles are detached by this air stream and the fiber bundles thus detached, together with the dissolved base fiber material, are used for the open end.
  • Spinning element are fed.
  • the fiber material causing the effects is therefore not dissolved, as was previously the case, by a mechanical dissolving device, but by the suction effect of the flowing air, to which this material is fed.
  • the air flow unevenly releases the fibers from the front end of the sliver retained by a feeder.
  • the distribution of the effect fiber material in the finished fancy yarn is left to chance as to the size and sequence of the fiber groups or fibers detached from the fiber sliver.
  • a normal delivery device without any control is therefore sufficient for carrying out the method, since it is not necessary to control the effects by variable feeding of the Effket fiber material.
  • This method according to the invention is particularly suitable for the production of yarns Suitable for color effects.
  • the method according to the invention is also very suitable for fine yarns in which effects cannot be produced in the desired gradation due to the inertia of the known device.
  • the flow rate of the air stream is much higher than the feed speed of the effect fiber material.
  • the effect fiber material is dissolved into fiber tufts in an effect material air flow and the fiber tufts detached in this way are mixed with it Effect material air flow are fed to the transport air flow for the basic fiber material.
  • the effect fiber material is advantageously supplied to the air stream during its acceleration.
  • the flow of the individual fibers detached from the base fiber material is not impaired if it is expediently provided that the effect fiber material is dissolved before the acceleration of the air flow has ended.
  • the transport air stream and the effect material air stream have essentially the same flow direction before they are combined.
  • the fiber material causing the effects is only dissolved pneumatically, but not mechanically.
  • the intensity of the air flow acting on the fiber material is of essential importance for the dissolution of the fiber band consisting of the effect fiber material.
  • the effect fiber material is expediently fed into the transport air stream for the base fiber material at the location of the greatest air speed.
  • Deviating effects can be achieved according to the invention when the same slivers are fed in that the constant feed speed of the effect fiber material is adjusted according to the desired effects.
  • the effect fiber material can also be supplied in the form of a plurality of fiber bands, wherein these two or more effect material fiber bands can also be supplied at different constant speeds.
  • the fiber feed channel has, according to the invention, a feed opening through which the effect fiber material passes through the fiber feed channel is supplied, which is supplied by the feed device at a constant speed.
  • the effect fiber material in the form of tufts of fibers is detached pneumatically in this way.
  • the fiber feed channel has cross-sectional areas with different speeds of the air flow guided by it and that the feed opening is arranged in the area of the higher flow speed in the fiber feed channel.
  • a band guide is advantageously provided which keeps the fiber band in the region of the higher flow speed.
  • the fiber band consisting of the effect fiber material is to be dissolved in time in the air stream in such a way that the fiber band changes the fiber orientation of the Individual fibers released from the basic fiber material are not impaired.
  • the feed opening is formed by the end of a fiber feed channel for the effect fiber material, the length of which exceeds the maximum stack length of the individual fibers contained in the effect fiber material.
  • the fiber feed channel for the effect fiber material is essentially in Longitudinal direction of the fiber feed channel for the basic fiber material opens into it. If the fiber feed channel for the base fiber material starts tangentially from an opening roller, then according to a preferred embodiment of the subject matter of the invention, the fiber feed channel for the effect fiber material forms the rearward extension of the fiber feed channel for the base fiber material.
  • the effect fiber material is fed to the base fiber material on its transport path between the opening roller and the open-end spinning element.
  • the interior of the opening roller housing in the area of the start of the fiber feed channel for the basic fiber material has an extension into which the fiber feed channel for the effect Fiber material opens tangentially to the opening roller.
  • a normal yarn can also be spun without effects by not feeding any fiber material into the feed opening.
  • the air sucked in through the feed opening does not impair the normal spinning process.
  • a closure member is assigned to the feed opening. This is advantageously arranged in the area of the undissolved sliver, so that when a fancy yarn is being produced, no fibers that have already been detached from the sliver can get stuck here.
  • An adjustable drive is advantageously assigned to the feed device, so that the constant feed speed of the effect fiber material can be determined in different ways compared to the base fiber material.
  • a pair of rollers or a drafting device can be used as the feeding device for the effect fiber material, the distortion in the drafting device being determined in such a way that the fiber ribbon warped in the drafting device is not dissolved into individual fibers, but also forms a fiber structure when leaving the drafting device, so that The tufts of fibers are removed pneumatically by an air flow.
  • the present invention enables, without tape preparation and random control, that a shift-resistant fancy yarn, in particular a yarn with color effects, can be produced in a simple manner, the effects in terms of sequence and size being left to chance.
  • the effect fiber material is not dissolved mechanically, so that no conventional dissolving device for the effect fiber material is required. If the fiber material provided is still too strong for direct pneumatic dissolution, the pair of rollers of the feed device can be formed by the pair of output rollers of a conventional drafting device, which, however, only warps the fiber material so far that a still closed, i.e. uninterrupted sliver emerges from this drafting system. This sliver is then released pneumatically.
  • the device according to the invention is thus very simple in construction. It is also not necessary with a favorable embodiment of the device according to the invention to increase the spinning vacuum, which generates the air flow causing the sliver to dissolve, compared to the normal spinning process, so that the device according to the invention is not only simple in construction, but also economical Operation is.
  • the open-end spinning device shown in FIG. 1 has, as the most important elements, a spinning element designed as a spinning rotor 1, a opening device 2 designed as opening roller 22 and a fiber feed channel 3 for the base fiber material 26, which extends from opening roller 22 to spinning rotor 1.
  • the spinning rotor 1 is arranged in a housing 10 which is connected via a connection 11 to a vacuum source, not shown.
  • the housing 10 is closed with a cover 12, through which the fiber feed channel 3 and a thread take-off channel 4 extend into the interior of the spinning rotor 1.
  • the feed opening 52 of a fiber feed channel 5 opens for the Effect fiber material 7.
  • a feed device 6 is arranged in front of the inlet mouth 50 of this fiber feed channel 5. In this case, a distance serving as an air inlet opening 51 is provided between the feed device 6 and the fiber feed channel 5.
  • the feed device 6 essentially has a pair of rollers which consists of a drivable feed roller 60 and a pressure roller 61 which rests elastically thereon.
  • the feed roller 60 is driven by a motor 63 at a constant speed via an overdrive 62.
  • the base fiber material 26 is supplied to the opening roller 22 arranged in a housing 25 in the usual way by means of a feed device 24 and is broken up into individual fibers 20 by the opening roller 22.
  • a transport air flow 9 is generated in the fiber feed channel 3 by the negative pressure present at the connection 11 of the housing 10. This transport air flow 9 serves as a transport medium for the individual fibers 20 leaving the opening roller 22.
  • this transport air flow in the fiber feed channel 3 causes an effect material air flow 90 to be created in the fiber feed channel 5.
  • the effect fiber material in the form of a sliver 7 is fed to the fiber feed channel 5 at a constant speed.
  • a slightly twisted sliver band or an untwisted stretch band can be used as the sliver 7.
  • this sliver 7 also forms a closed, ie uninterrupted, company even after it leaves the feed device 6 association.
  • a strong suction effect is exerted on the leading end 70 of the sliver 7 by the aforementioned effect material air flow 90, which penetrates into the fiber feed channel 5 through the air inlet opening 51.
  • the leading end 70 flutters back and forth in the fiber feed channel 5 and is turned open when the fiber sliver 7 is a twisted fiber sliver.
  • Individual fibers and tufts of fibers 71 are irregularly released from the fiber sliver 7 by the air and, with the aid of the effect material air flow 90, are conveyed through the feed opening 52 into the fiber feed channel 3, where they emerge from the Mix sliver 7 of individual fibers and tufts of fibers 71 with individual fibers 20 released from the basic fiber material and together with the individual fibers 20 of the dissolved basic fiber material 26 are fed to the open-end spinning element, for example a spinning rotor 1.
  • the sliver 7 is thus purely pneumatic, the effect being controlled solely by the fiber friction.
  • the individual fibers and tufts 71 are pneumatically released from the sliver 7 in an irregular manner, so that they differ in sequence and size. Therefore, even after the union and mixing of the individual fibers 20 and fiber tufts 71, no homogeneous fiber mixture is produced.
  • the resulting fancy yarn 40 is thus also irregularly patterned, although no effect control devices are provided. The random distribution of the effects results automatically from the removal of fibers and tufts of fibers 71.
  • any fiber materials can be spun together in the manner described and with the aid of the device described. However, the effects appear most clearly when the spinning rotor 1 is supplied with fiber material of different colors or hues via the two fiber feed channels 3 and 5. This creates a yarn with uneven color effects.
  • the fiber feed channel 5 is of such a length that the dissolution of the fiber band 7 into individual fibers and fiber tufts 71 with the aid of the effect material air flow 90, i.e. still in the fiber feed channel 5, before this opens into the fiber feed channel 3 with the transport air flow 9.
  • the leading end 70 of the sliver 7 thus does not protrude into the transport air flow, which conveys the individual fibers 20 detached from the base fiber material 26, and thus cannot adversely affect the fiber transport from the opening roller 22 to the spinning rotor 1.
  • the length of the fiber feed channel 5 is selected so that it exceeds the maximum stack length of the individual fibers 71 contained in the effect fiber material. In this way, the effect fiber material, which has already been broken down into individual fibers 71, is introduced into the transport air stream 9 for the base fiber material with the aid of this effect material air flow 90.
  • the fiber feed channel 5 is shorter than in the above-mentioned example when the space is limited.
  • the leading end 70 of the sliver 7 should, however, protrude only so far into the fiber feed channel 3 that the fiber transport between the opening roller 2 and the spinning rotor 1 is not significantly disturbed. It has been shown that this - provided the inside diameter of the fiber feed channel 3 is sufficient - is generally the case when the fiber feed channel 5 has a minimum length which is greater than the minimum staple length of the individual fibers 71 contained in the effect fiber material.
  • FIG. 3 which shows a modification of the device shown in FIG. 1, it is provided that the transport air flow 9 and the effect material air flow 90 in the fiber feed channels 3 and 5 have essentially the same flow direction even before they are combined. Since in the exemplary embodiment shown in FIG. 3 the fiber feed channel 5 forms the rearward extension of the fiber feed channel 3, the fiber feed channel 5 opens into the fiber feed channel 3 essentially in the direction of flow of the transport air flow 9. However, the same is also achieved if, in a modification of the device shown in FIG. 1, the angle ⁇ between the two fiber feed channels 3 and 5 is chosen to be correspondingly large.
  • FIG. 3 shows a very early feeding of the effect fiber material into the above-mentioned transport air flow for the basic fiber material 26, namely tangentially into the housing 25 of the opening roller 22.
  • the interior space receiving the opening roller 22 has in the area of the beginning of the fiber feed channel 3 for the base fiber material 26 is an extension 27, so that the individual fibers 20 of the base fiber material 26 can already detach from the clothing of the opening roller 22 before they leave the interior of the opening roller housing 25.
  • the fiber feed channel 5 for the effect fiber material 7 opens into this extension 27 of the interior in such a way that the fibers and fiber tufts 71 of the effect fiber material still get into the opening roller housing 25, but without coming into contact with the clothing of the opening roller 22 to get.
  • the fiber feed channel 3 for the base fiber material 26 has a first conical channel section 30 and has a second, substantially cylindrical channel section 31.
  • the feed opening 52 of the fiber feed channel 5 for the effect fiber material 7 opens into the fiber feed channel 3 in the region of the first, ie the tapering, channel section 30.
  • the transport air flow 9 is initially accelerated, with the exception of the individual fibers 20 of the base fiber material 26, the individual fibers 71 of the effect fiber material delivered into the accelerating transport air flow by means of the effect material air flow 90 are also stretched.
  • the leading end 70 of the The sliver 7 extends at most into the conical channel section 30 of the fiber feed channel 3, so that the detachment of the fibers 71 takes place before the acceleration of the transport air flow 9 has ended.
  • the combined air flow then passes into the cylindrical channel section 31, through which the air flow flows essentially at a constant speed.
  • the individual fibers 20 and fiber tufts 71 which due to their inertia can only delay the acceleration of the air, are subsequently accelerated in the calming phase in the cylindrical channel section 31, their stretching and parallel orientation being improved.
  • the described device can be modified in various ways by exchanging features with equivalents or other combinations.
  • the special design of the feed device 6, for example is irrelevant.
  • a drafting device can also be provided (see input roller pair 64 and output roller pair 65), which reduces the fiber sliver 7 fed to such a thickness that this in the air flow in the second fiber feed channel 5 - and possibly in the first fiber feed channel 3, if the leading end 70 of the fiber band 7 extends into this first fiber feed channel 3 - can be broken down into individual fibers and fiber bundles 71.
  • the speed ratios between the input roller pair 64 and the output roller pair 65 - and possibly other roller pairs - are chosen so that the sliver 7 fed is reduced to the desired thickness, but is in no way resolved into individual fibers and fiber tufts 71.
  • the open-end spinning element can also be designed as desired.
  • a pair of friction rollers 13 is therefore shown in FIG. 3 as an exemplary embodiment of such a spinning element.
  • the air flow sucked in by the spinning element is weaker than in rotor spinning. For this reason, the air flow can also be increased if necessary by compressed air supplied by means of an injector nozzle (see compressed air nozzles 58 and 59).
  • the fiber feed channel 5 for the effect fiber material 7 can still be omitted under certain circumstances.
  • the band-shaped effect fiber material is then introduced into the fiber feed channel 3 through a feed opening 52, with a correspondingly selected distance of the feed device 6 from the feed opening 52 and thus from the fiber feed channel 3 ensuring that the fiber ribbon 7 only extends so far into the fiber feed channel 3, that proper dissolution of the effect fiber material is guaranteed there.
  • the opening roller 22 has a sawtooth-like clothing winding 8.
  • the screw-like passages of the clothing winding 8 move the air from one end face 28 of the opening roller 22, at which the end 80 leading the rotation (arrow 21) of the opening roller 22 the clothing winding 8 is in the direction of the end face 23, on which the trailing end 81 of the clothing winding 8 is located, or vice versa.
  • the direction in which air migrates laterally depends on whether the peripheral speed of the opening roller 22 is greater than that Air speed is or vice versa. The air speed thus increases over the cross section in the direction of the end face 23 or 28 of the opening roller 22.
  • the effect fiber material is fed into the transport air stream 9 for the basic fiber material 26, based on the cross section, at the location of the greatest air speed .
  • this should be at the front side 23 of the opening roller 22, which is why the fiber feed channel 5 in this embodiment opens into the fiber feeding channel 3 offset toward the front side 23 of the opening roller 2.
  • the feed opening 52 opens into the fiber feed channel 3 in the region of the higher flow velocity, namely on the side of the fiber feed channel 3 to which the air is conveyed through the clothing winding 8.
  • a tape guide 66 (FIG. 5) is arranged before the introduction of the fiber ribbon 7 into the second fiber feed channel 5 so that it holds the fiber ribbon 7 on the side of the fiber feed channel 5 on which the greater air speed forms in the fiber feed channel 3.
  • the feed device 6 to the motor 63 (FIG. 1) in such a way that the transmission ratio can be set to different values. This can be done, for example, by replacing gear wheels on the drive shafts of motor 63 and feed roller 60. Depending on the desired intensity of the effects, a higher or a lower feed speed can thus be selected for the feed device, but this then remains constant during the production process.
  • a further fiber feed channel 57 with an air inlet opening 53 and a feed opening 56 and a feed device 67 opens into the fiber feed channel 3 in order to feed effect fiber material in the form of a further sliver 72.
  • the feed device 67 also consists of a feed roller 670 and a pressure roller 671. The feed roller 670 is driven by the motor 63 by means of an overdrive 620.
  • the feed devices 6 and 67 become from the motor by suitably determining the transmission ratio 63 driven out at different constant speeds.
  • the effect fiber material of different fiber tapes 7 and 72 can be fed to the fiber feed channel 3 through several or a single feed opening, depending on the space available. In the latter case, the dissolved or still to be dissolved effect fiber material is brought together at the latest at the common feed opening.
  • the sliver 7 and / or 72 can be retained by the feed device 6 or 67 while it is exposed to the air flow.
  • a retaining or tear-off edge 54 can be provided between the feed device 6 or 67 and the first fiber feed channel 3. According to FIG. 1, this is located between fiber feed channel 5 and fiber feed channel 3.
  • a tear-off edge 54 is provided at this point, while a tear-off edge 55 designed as a pin is provided at a kink in the fiber feed channel 57.
  • Such a tear-off edge 54 or 55 is very important, since it limits the effect of the air on the free end of the sliver 7 or 72. In this way it is avoided that too large pieces of fiber can get into the spinning element, which could lead to thread breaks.
  • the fiber feed channel 5 can also be assigned a controllable closure member 91, which in its closed position prevents such an air supply.
  • the closure member 91 in the embodiment shown in FIG. 3 is in that area of the fiber feed channel 3 in which the sliver 7 is still has not been broken down into individual fibers and fiber bundles 71.
