Definitions
- the invention relates to a device for treating filament yarn by means of a nozzle having a yarn channel, which is formed as an open and split nozzle with threading and Mediumzuschreibkanal in the yarn channel and a method for treating filament yarn by means of a yarn channel having a nozzle, which divided open nozzle with free threading slot and medium feed channel is formed in the yarn channel.
- the invention further relates to a knotted yarn, a migrated yarn and a false twisted yarn.
- Filament yarn is subjected to an air treatment during the spinning process after the spinning process, so that the cohesion of the individual filaments for the yarn processing is improved.
- the swirling purpose is primarily to improve the cohesion and also to increase the reliability, eg when winding and unwinding the filament yarn.
- the aim of the migration is to give the thread a sufficiently good cohesion in the immediately following processing of the yarn, so that the subsequent direct interventions can be carried out without disruption.
- the filaments in the thread composite are only slightly crossed, so that no individual filaments protrude from the thread.
- migration was carried out using normal vortex nozzles. It was worked for a swirl with the worst possible operating conditions, so that almost no knots emerged.
- Migration and swirling have the sole purpose of improving the cohesion of the single filaments of the thread for yarn processing, as well as the winding up and shedding with the many deflections.
- the goal is to prevent malfunctions and yarn breakage without creating a disturbing effect on the finished fabric through the knots.
- the aforementioned treatments with single or multiple nozzles are used.
- the nozzles are used as double nozzles.
- the number of nozzles corresponds to the number of yarn runs. These can be 6 to 12, 16, 20 and recently even 24. The next goal is a doubling to, for example, 50 yarn runs.
- a nozzle body is shown in US-PS 5 1 57 819.
- the nozzle body consists of a larger number of flat plates, which can be clamped together via a screw connection.
- the yarn channel is formed by means of through holes perpendicular through each plate. The through holes are precisely matched in each plate, so that in the assembled state through all plates through a cylindrical, closed yarn channel is formed.
- plates with and without air supply channels can be formed and clamped together as a package with two end plates. It is a closed nozzle without Einfädelschlitz ..
- the aim of the solution according to US-PS 5 1 57 81 9 was the largest possible number of air supply channels, which was intended to produce both knot yarn and false-twisted yarn with the same nozzle concept.
- JP-200375802 shows an open, split air nozzle for the production of knotted yarn.
- a medium or air supply element of the split nozzle body consisting of a nozzle body and a baffle or cover plate, assembled. Both parts are individually screwed to the Heilzubowlement.
- the nozzle body has an air supply channel and a transverse bore for blowing the treatment medium into the yarn channel.
- yarn channel profiles are mounted both in the nozzle coiler and in the cover plate. Only in Miltongabaut state is formed between the nozzle body and the cover plate of the yarn channel. Between the two bodies, a gap is provided, which forms the Einfädelschlitz on the side facing away from the air supply element.
- the nozzle is a typical swirl nozzle with approximately central and vertical arrangement of the air supply in the yarn channel.
- at Two- or multiple nozzles would both nozzle body and cover plate have to be used two or more times, which is a disadvantage in terms of a narrow pitch for the Gamcopy.
- a special case for the application of turbulence are water treatment plants. 500 to 2000 parallel yarn runs are treated simultaneously in very close pitch.
- EP 0 216 951 shows such a special device for swirling multifilament yarns.
- the turbulence takes place on two levels, an upper level and a lower level.
- the Verwirbelungskanäle are arranged for the corresponding number of yarn runs in a very small space, so that the crowd of warp threads can be fed with a very close distance.
- the swirling device has a number of parallel juxtaposed slots. These are formed between disks and spacers of a nozzle rod.
- the individual disks have an annular shape, wherein compressed air is supplied to each disk above the central region and supplied via respective transverse bores to the individual swirling zones formed as slots.
- the threads are transported at a distance from the slot bottom, in the area of influence of the blown air, through the device.
- the discs have both inlet side and outlet side yarn guide. With the assembly of a plurality of discs with intermediate elements, end to end, so-called nozzle rods are formed.
- the solution is extremely space-saving. The result is a pitch for the yarn runs in the order of 4 mm. So that the warp threads can not jump out of the treatment slits, in the outer area of the. Slotted a wire.
- the discs are made of ceramic, especially oxide ceramics. This results in a long service life, wherein the ceramic discs are produced by the molding process and then fired.
- the swirl force of the blown air is used to over an immediately upstream thermal treatment by heating and cooling of the yarn to change the molecular structure of the individual filaments permanently, so that the yarn is a considerable bulk.
- the false twist reference is made to EP-PS O 532 458, with the false twisting the filament yarn and the finished fabric a bulky, textile character to be given.
- Nozzles with a permanently open threading slot are referred to as open nozzles, such as e.g. in EP 0 532 458 and WO03 / O29539 ( Figure 8).
- nozzles which can be brought by a sliding plate in an open threading position and a closed operating position. These are referred to as open-ended nozzles, such as e.g. in EP 0 21 6 951 and WO03 / 029539 (FIG. 8a).
- the inventors have now taken on the task to seek solutions to develop low-cost nozzles for the yarn treatment in the context of open nozzles, even for divisions between two or more parallel yarn runs in the field of a few millimeters, the concept should be used in particular for single or double nozzles.
- the device according to the invention is characterized in that the nozzle is formed by nozzle / cover plates which each have a nozzle and cover plate side can be assembled on a medium supply element and form a yarn channel between two adjacent nozzle / cover plates.
- the inventive method is characterized in that the yarn for the treatment between two same, together forming a yarn channel plates is guided, wherein the plates are sealed to each other and with respect to the medium supply side.
- the knot or migrated yarn according to the invention in particular as a microfilament yarn, is characterized in that, for the treatment, it is guided between two identical plates which together form a yarn channel and a knotted yarn or migrated yarn is produced.
- the false-twisted yarn according to the invention is characterized in that it has been guided and false-twisted for the treatment between two identical plates forming a yarn channel.
- the new solution brings several decisive advantages.
- the shape of the plates, in particular the ceramic plates, is limited to the actual core functions, namely:
- the nozzle / cover plates of a nozzle are the same.
- Each of the nozzles / cover plates has the two functions nozzle plate and cover or baffle plate in it.
- Separate cover plates, such as according to JP-20-0375802 omitted. This already allows in principle a closer pitch for multiple yarn runs.
- the plates can be made with very small external dimensions of eg 1 cm by 2 cm and a thickness of 4 mm or less.
- the simple plate shape results in their production, especially in ceramics, enormous relief, since this now with the much cheaper injection molding can be made. At least the blanks for the plates can be produced in larger quantities and thus cheaper.
- the plates of a nozzle can be made identical, they can be installed rotated in the case of a single nozzle of 180 °, so that with the still unused Garnkanalprifolen with respect to the wear in their life a doubling can be achieved.
- the new solution allows, as will be explained, the production of the plates by injection molding, which is much cheaper than the pressing method, for example according to EP 0 216 951.
- the second enormous advantage is that the yarn channel, which is designed as a mere slot in EP 0 216 951, according to the new invention of the specific treatment can be adjusted.
- the wheels of EP 0 216 951 have the enormous advantage that two yarn runs form between two wheels.
- the disadvantage of the solution according to EP 0 216 951, however, is that with the simultaneous integration of the yarn guide and the air supply in the plate concept almost palm-sized slices arise, which can be produced only in the pressing process.
- the new plate concept can be used in various treatment processes such as swirling, migrating, false twisting and other textures on filament yarns. It can also be used in reed plants as a multiple nozzle and in texturing plants as a single or double nozzle, but also in stretching plants and false twist texturing plants.
- the same nozzle / cover plates are used for single nozzles, double nozzles or multiple nozzles, each in a specific application.
- Each of the nozzle / cover plates has both a nozzle plate side as a cover plate side and preferably also each air supply channels.

- Each of the at least two plates of a nozzle is identically formed at least with respect to the yarn channel profiles and each has a nozzle plate side and cover plate side yarn channel profile, which forms a yarn channel only in the assembled state. Because only two plates together form a yarn channel, there are two unused outer sides for each pairing of two or more plates. In the case of a simple nozzle, this has the great advantage that, after greater wear on the active yarn channel profiles, both plates can be installed turned by 180 °, so that the service life of a nozzle can be doubled.
- the nozzle / cover plates are preferably formed as ceramic plates or at least in the region of the yarn channel profile on a corresponding highly wear-resistant surface coating.

On both sides of the nozzle block, a stable end plate can be attached, over which the ceramic plates are clamped together.
- the medium supply element may further comprise a support base, on which each of the nozzle / cover plates of the nozzle block is tightly fastened via the clamping notches.
- the support base or the end plates can be provided with a color coding, so that it is recognizable by the color, which nozzle types are installed.
- the nozzle block is mounted on a Mediumzu Glasssockel with built-air feed channel, with which the air supply ducts to be activated are connectable.

- the stationary swirl flow goes directly into a transient turbulent flow.
- the blown air is displaced in the entry region into the yarn treatment channel in a twisting chamber which is short in the yarn channel longitudinal direction and into two strong stationary swirl flows undisturbed by filament bundles.
- a short region with a stable swirl flow is generated in the air swirl chamber, followed by an alternating swirl zone in both the yarn transport direction and the yarn transport direction.
- a pressure of 0.5 to 1, 5 bar is used for the blowing air, for the production of soft knots, which can dissolve in the further processing, or it is for the blowing air compressed air of about 1, 5 bar used for the production of hard knots, which do not dissolve in the further processing.

- the air swirl chamber results from the two small KalottenausappelInstitut 42.
- FIG. 9a is a drawing which schematically illustrates the two flow forms. Only recent studies have shown that knowledge of knot formation was very incomplete. In fact, knot formation does not simply arise from the two stable double vertebrae. A basic requirement for knot formation is the following fact:
- FIG. 9b shows above smooth, that is untwisted yarn 2. With the straight lines the individual filaments are indicated. Second, a soft swirled yarn. Typical are the rather shorter nodes K, where the nodes are symbolized by thin straight lines. The third plot shows hard, relatively long nodes K between the swirling open spots. The hard knots are symbolized by thicker lines. The fourth illustration shows a typical knot yarn of the prior art with very irregular knots.
- FIG. 9c shows some examples with irregular nodule formation.
- Figure 9d is a comparison of hard and soft nodes that can be produced with the new invention.
- FIG. 9d shows a typical associated area of the use of compressed air of 1.5 to 3 bar or 0.5 to 1.5 bar.
- hard knots or soft knots are required.
- the new solution according to FIG. 10a proposes the supply of primary air (PL) as well as of secondary air (SL). Because, in the example, the compressed air supply is slightly inclined in the transport direction, a stronger swirling flow in the direction of the yarn channel outlet Ak2 arises. This can be seen from the larger line concentration in the exit region.
- PL primary air
- SL secondary air
- two auxiliary bores for secondary air SL are arranged inclined relative to one another in the transport direction at an angle ⁇ . Both auxiliary bores are arranged symmetrically in the respective edge regions of the yarn channel, as marked by the distance Z. As a variant, the possibility is indicated by ⁇ 1 .

- FIGS. 10b and 10c show two examples of the arrangement dre main bore 50 and the auxiliary bore 51 for the secondary air (SL).
- Figures 11a to 11d show the use of the new nozzle as a detonation nozzle for the final twisting of filament yarn with various forms of air injection and threading slot.
- a multifilament yarn 22 to be textured is fed via a first heating device 60 to a rotary encoder 61, eg a friction twisting device.
- the textured yarn leaving the swirler 61 is bulky and highly elastic.
- the rotation imparted to the yarn by the swirler 61 has been resolved after the swirler.
- a twisting moment prevails here in the yarn, which tends to twist the yarn again.
- the yarn is then suitably guided in a known manner by a second heater 62 connected downstream of the swirl generator 61, which reduces the elasticity of the yarn.
- the second heating device 62 is followed by a nozzle 63 according to the invention which again gives false twist to the yarn passing through the heating device 62, in a direction opposite to the direction of the twist generated in the swirling sensor 61.
- the nozzle 63 is from a compressed air line 64 supplied with compressed air.
- the nozzle 63 has a blowing air duct 65 opening tangentially into the yarn duct 1 7.
- Figures 1 1 a to 1 1 d also show a single nozzle, but in use for the generation of a false twist on the yarn.
- the two plates must be formed for the generation of false twist with tangential air inlet.
- the two plates are designated according to their other function by the reference numerals 1 'and 1 ".
- FIG. 12 shows a parallel POY / HOY spinning system. In this process, it has no pulleys. It is only possible to regulate the yarn tension for the swirling with the winder speed. This solution is mostly used in Europe and the USA.
- FIG. 13 shows a POY spinning system with deflection rollers. The advantage of this POY process is that you can better regulate the thread tension. The pulleys are not heated during the process. This solution is mostly used in Asia but also in Europe and the USA.
- FIG. 14a shows an FDY process with a migration and a swirling. This is the standard in FDY spinning. In this process you have two heated Mono's or Duo's. Here the thread tension can be adjusted well.
- Figure 14b is an FDY process (H4S or H5S) and is an example of pre-swirling as well as swirling. This process has cold godets for stretching, and then the yarn is steam-relaxed.
- FIG. 14c is a FDY process showing successively one migration and two swirls. In this process, the yarn is heated with a heater before preparation and then stretched with cold godets.
- Figure 14d is an FDY process showing migration as well as swirl but without heat input. Here, the yarn is exposed to hot air before preparation and then stretched with cold godets.
