Definitions

  • the invention relates to a texturing nozzle for the treatment of a filamentary material in a treatment channel formed between at least two superimposed basic bodies with at least one nozzle body for supplying a gaseous treatment medium and at least one venting part in the treatment channel.
  • Multifilaments are made of synthetic polymers, for example of polypropylene, polyamide, polyester or the like. Threads produced, which find application in various fields.
  • Means for producing multifilament threads include an extruder in which the starting material is melted in the form of granules and pressed through a spinneret. Depending on the desired number of filaments per thread, the spinneret has a corresponding number of holes through which the plastic material is pressed.
  • the holes of the spinneret can also have other cross-sectional shapes in addition to round cross-section, in order to give the filaments special properties.
  • the extrusion process is followed by a cooling process, after which the filaments are combined to form the thread.
  • a texturing of the specified type is, for example, in the US 4,949,441 or the corresponding one EP 495 886 B1 described.
  • a filament yarn is sucked through an injector and pulled with hot compressed air, which is deflected accordingly, down. After that, the yarn hits at high speed and plasticizing temperature in one with many Slits chamber on a cotton yarn plug, which he kinked very often and unevenly, so crinkled.
  • the yarn is passed over suitable cooling drums for cooling and then usually swirled in a further step, ie knots are introduced, so that the filaments are fixed in the yarn before the yarn is wound on corresponding coils.
  • the texturing nozzle consists of a base body, a cover plate and intermediate inner plate, which consists of a stack of layers, one of which forms a longitudinal channel, the cross section of which changes between the inlet and outlet of both the width and the height.
  • the base body is provided with two spaced bores through which a fluid for the treatment of a run through the channel strand material is supplied.
  • the stack-shaped coating of the inner plate has the advantage that when wearing the channel walls only the layer forming the channel must be replaced.
  • this advantage is achieved with the disadvantage that the construction of an inner plate with stacked layers is associated with a high outlay both in the production and in the assembly.
  • the DE 30 19 302 A1 discloses a nozzle for entangling yarns with a closed yarn path channel of rectangular cross-section and gas supply channels, in which the channel widens stepwise on one broad side or on both broad sides, with the extensions of the yarn path narrowing again to the original cross section.
  • the US 3 638 291 A describes a texturing nozzle in which the body forming the channel consists of only two parts whose opposite surfaces are planar, wherein in the surface of the one body the Garnlaufkanal is formed, which has a constant depth and has lateral recesses.
  • the DE 38 29 150 A1 describes an air nozzle for pneumatic false twist spinning, which consists of sections.
  • the section which is arranged after the section containing the compressed air channels, is made of a harder, more wear-resistant material, such as ceramic constructed.
  • the DE 39 27 910 A1 describes a false twist nozzle for pneumatic false twist spinning, in which at least a part of the inner wall to reduce the cross section of the outlet opening the blow duct is provided with a coating or an insert, which consists for example of ceramic.
  • the last two documents describe a staple fiber spinning process in which the yarn is not crimped or necked but stretched and formed in the air jet into a low strength yarn.
  • the technology described in these documents therefore differs substantially from the technology of the present invention.
  • the inserts can be replaced only with relatively high effort.
  • the object of the invention is to provide a texturing, which is characterized by ease of manufacture, easy installation and easy maintenance.
  • the more sensitive and rapidly worn components of the texturing nozzle should be easily and quickly exchangeable.
  • yarns having as good as possible and also as symmetrical properties as possible should be producible.
  • An adaptation of the texturing to different yarn properties should be as quick and easy to carry out without the entire texturing must be replaced.
  • the treatment channel is formed at least in some areas with a more resistant material than the main body.
  • the more resistant material is made of ceramic material. Aside from the poorer machinability, ceramics have a variety of advantages.
  • the more resistant material is provided by an insert in the base body. This causes a quick and easy replacement of worn components without the need to replace the entire texturing.
  • the texturing nozzle can be easily adapted to changed conditions such as changed yarn properties.
  • the more resistant material may also be provided by an attachment on the base body.
  • the insert or attachment includes the nozzle body of the texturing nozzle.
  • the nozzle body is a particularly susceptible to wear component of the texturing.
  • the yarn properties are significantly influenced by the nozzle body.
  • the suspension can be formed by cuts in the insert.
  • the treatment channel in the venting part has a square cross-section with od through perforated plates od. Like. Venting windows formed on each side of the treatment channel. Due to the symmetrical design of the venting part as symmetrical outflow of texturing and thus uniform yarn properties is achieved. In addition, undesirable propagation of the twist can be effectively prevented.
  • the distance between the texturing die and the cooling drum can be kept very short.
  • the speed of the plug can be appropriately controlled by the speed of the cooling drum.
  • the texturing nozzle according to the invention results in a flow guide which, together with the exhaust zone and the preferably square design of the treatment channel, results in a very compact grafting with a very uniform graft density and a very high and uniform crimping in the yarn.
  • the combination of this optimum symmetric plug formation and the subsequent cooling phase enables yarns with very low shrinkage values, so-called boiling shrinkage, to be produced in the range from 0.5% to a maximum of 1%. This shrinkage is lower compared to that of conventional BCF yarns, which is usually in the range of 3% to 4%.
  • Fig. 1 is the plan view of the main body 1 of a texturing illustrated.
  • the thread to be textured is introduced into the texturing nozzle.
  • the nozzle body 5 is formed by supply channels 3 for the gaseous treatment medium.
  • the treatment medium preferably air or superheated steam, is injected at very high speed via the supply channels 3 into the treatment channel 6, so that at the exit point 4 of the nozzle body 5, a swirl generation occurs, which deforms the thread accordingly.
  • the storage zone 7 of the treatment channel 6 there is at least one venting part 8, via which the injected gas is sucked off.
  • the channel cross-section in the guide part 9 can be designed to be tapered.
  • the cross-section of the treatment channel 6 can be round, square or rectangular and varies in its dimensions at least in partial areas between the inlet and exit of the filamentary material to be treated.
  • Fig. 2 shows a texturing nozzle consisting of two basic bodies 1 in the unfolded state.
  • the two basic bodies 1 of the texturing nozzle can be closed manually, pneumatically, hydraulically or electrically.
  • the two main body 1 are usually not symmetrical.
  • the treatment channel 6 is provided only in a main body 1 of the texturing, while the opposite base body is made flat.
  • the treatment channel 6 is advantageously formed at least in some areas with a more resistant material than the base body 1, whereby a harmful influence of the treatment medium is avoided as much as possible. In this way, a coating or lining may be made of more resistant material, such as ceramic.
  • a coating or lining may be made of more resistant material, such as ceramic.
  • the treatment channel 6 is formed by an insert 10, which is provided for forming the aforementioned coating or lining and made of durable material and is embedded in a corresponding recess of the base body 1.
  • the insert 10 can be connected by corresponding bolts or screw with the base body 1.
  • a resilient mounting of the insert has advantages because when folding the base body 1 of the texturing an optimal contact pressure is caused.
  • the coating, lining or insert 10 may also be present only in partial regions of the treatment channel 6. What is important is a more resistant design in those areas where the treatment channel 6 becomes wider, ie, where the thread is crimped, since in these areas the wear of the wall of the treatment channel 6 is greatest.
  • the insert 10 includes the nozzle body 5 of the texturing nozzle.
  • the insert 10 is inserted perpendicular to the longitudinal direction of the treatment channel 6 in the base body 1 and screwed or connected with this accordingly.
  • a magnetic connection between the base body 1 and insert 10 is possible.
  • the nozzle body 5 is also included in the insert 10, but used in the base body 1 at the thread inlet channel 2 in the longitudinal direction thereof.
  • an attachment 11 contains the nozzle body 5.
  • the attachment 11 is on the input side to the front side of the main body 1 of the texturing nozzle attached. Similar to the inserts 10 shown or attachments 11 for forming the nozzle body 5, these can also form the treatment channel 6 or parts thereof. As a result, wearing parts of the texturing nozzle can be replaced quickly and easily, or the texturing nozzle can be easily adapted to changed yarn properties.
  • Fig. 6 to 8 show a perforated plate 12, which are used to form the venting part 8 of the texturing in the storage zone 7 of the treatment channel 6.
  • two such perforated plates 12 are arranged in the treatment channel 6.
  • an optimal suction of the air is ensured on all four sides of the treatment channel 6, whereby the yarn receives particularly symmetrical properties.
  • slots can also be provided, which however are disadvantageous in the case of particularly thin plates in relation to holes 13.
  • the holes 13 are more susceptible to contamination.
  • the perforated plates 12 can be connected via corresponding magnets, which are arranged in the main body 1 of the texturing, with this. Instead of the perforated plates 12 also inserts with the corresponding perforations can be provided (not shown).
  • Fig. 9 shows an embodiment of a round insert 10 for forming a nozzle body 5 of the texturing, each of which comprises a supply channel 3 for the gaseous treatment medium on both sides of the channel for the thread. Due to the design of the nozzle body 5 as an insert 10 this can be replaced quickly and easily when worn. Even with desired changes in the yarn properties of the insert can be changed.
  • the insert 10 is made of more resistant material than the base body 1. A production of the insert 10 made of ceramic materials is possible.
  • the supply channels 3 can also be designed asymmetrically. Just by the execution of the nozzle body 5 as an insert 10 make such changes to achieve different yarn properties only make sense.
  • the yarn passes after the texturing nozzle on a cooling drum and is then wound up on appropriate roles and is thus available for further processing. It is advantageous to keep the distance between texturing and cooling drum as short as possible.
  • the guide part adjoining the texturing nozzle can be made asymmetrical and the texturing nozzle can be brought to the cooling drum in such a way that it forms the other part of the guide.
  • the plug is fed directly to the cooling drum and the plug speed is regulated by the cooling drum speed. To fix the plug on the cooling drum is usually a multiple wrap.
  • Fig. 11a and 11b show the top view and side view of a circular insert 10 to form the nozzle body 5 of the texturing. Close to the thread inlet channel 2 on both sides Supply channels 3 for the gaseous treatment medium. The twisted thread is forwarded at the exit point 4. As can be seen from FIG. 11 b, the insert 10 has a series of indentations 14 or the like, which are designed such that a spring action results when the insert 10 is inserted into the main body 1 of the texturing nozzle.
  • Fig. 12a and 12b show a texturing, consisting of two superposed bodies 1 and a molded or guide member connected thereto 9.
  • the Texturierdüse shown is designed for the simultaneous production of two yarns.
  • Dashed lines drawn are the two parallel treatment channels 6 and the parallel arranged vent parts 8.
  • Each vent part 8 includes a channel of the guide member 9, in which the Garnpfropfen is forwarded until it is finally wrapped on a cooling drum (not shown).
  • the Garnpfropfen are guided by brake rails 15 which are pivotally mounted via a hinge 16 in the guide member 9, before they are the cooling drum (not shown) supplied.
  • the guide member 9 may also be made in one piece with a base body 1 of the texturing.
