Definitions
- the invention relates to a method for Lucasblastextu ⁇ réelle of continuous filament yarns with an Heilblastextu ⁇ erduse for the production of loop yarn with high transport speed, further a yarn finishing device with a Textu ⁇ er stretch, consisting of a delivery unit 1 for the delivery of the yarn, a Textu ⁇ erduse with compressed air supply and a delivery unit 2 immediately after the Textu ⁇ erduse, the delivery plants are designed for a transport speed of over 600 m / min.
- the invention is based on a Lucasblastextu ⁇ réelle according to WO97 / 30200.
- the finishing of continuous filament yarn has two main tasks.
- the yarn, made from industrially produced filaments should be given a textile character and also textile properties.
- the yarn is to be refined with regard to specific quality characteristics of the end product, which very often cannot be achieved by products made with natural fibers.
- a very primary goal, in the case of industrially produced filaments or the yarns and flat structures produced from them, is then to optimize the processing process.
- Optimizing here means maintaining or increasing certain quality factors and reducing production costs.
- production costs can be reduced in various ways. The most obvious way is to increase the throughput speed in a given production plant.
- a second possibility lies in procedural interventions, which do not necessarily include an increase in throughput speed, but ensure certain quality parameters even at high yarn throughput speeds
- the textile industry is, especially in the case of continuous filaments, one of the most complex branches of industry in that several independent branches of industry and fabric are involved, from the raw material to the finished flat product.Neither branch is completely autonomous, rather it is a processing chain at that each process change in one stage is preceded by the subsequent ones or at most - 2 -
- the object of the invention was now to optimize the processing process in the production of a loop yarn. Part of the task for the process was in particular to allow higher yarn transport speeds without loss of quality.
- the method according to the invention is characterized in that the yarn finishing with a high transport speed of over 600 m / min, in particular of over 750 m / mm. he follows,
- the loop yarn is produced as the main yarn treatment stage via an air blast texturing with an acceleration channel at the exit of the yarn treatment nozzle
- the yarn treatment main stage upstream and / or downstream heat treatment.
- FIG. 2 shows, purely schematically, the texturing of the prior art as was assumed in WO97 / 30200.
- Two main nozzle parameters are highlighted.
- the texturing according to the teaching of WO97 / 30200 is shown at the top right with increased performance. It can be seen very clearly that the values Oe-Z2 and DAE are larger compared to the nozzle T31 1 P, ie already in the cylindrical section VO, is referred to as the pre-opening.
- the dimension Vo greater than d is preferably selected.
- the invention further relates to a yarn finishing device and is characterized in that a yarn heating device is arranged immediately after the texturing nozzle, in front of the delivery unit 2 and / or immediately before the texturing nozzle after the delivery unit 1.
- a yarn heating device is arranged immediately after the texturing nozzle, in front of the delivery unit 2 and / or immediately before the texturing nozzle after the delivery unit 1.
- FIG. 1 shows an overview sheet of the new texturing process
- 2 shows a comparison of a texturing nozzle with Mach> 2 and one
- FIG. 4 shows a text route according to the invention
- Figures 5a to 5d different variants for the use of heat treatments
- FIG. 1 shows a schematic overview in relation to the new texturing process.
- the separate process stages are progressively shown from top to bottom.
- Smooth yarn 100 is fed from above via a first delivery unit LW1 at a given transport speed V 1 to a texturing nozzle 1 01 and through the yarn duct 1 04.
- Compressed air ducts 1 03 which are connected to a compressed air source P ', are used to compress highly compressed, preferably not heated, air under one Angle ⁇ is blown into the yarn channel 1 04 in the direction of transport of the yarn.
- the yarn channel 1 04 opened conically in such a way that a highly accelerated air flow with an overview, preferably with more than Mach 2, occurs in the conical section 102.
- the shock waves generate the actual texturing, as is described in detail in WO97 / 30200 mentioned at the beginning.
- the first section from the air injection point 105 into the yarn channel 104 to the first section of the conical extension 102 serves to loosen and open the plain yarn so that the individual filaments are exposed to the supersonic flow.
- the texturing takes place either within the conical part 102 or in the outlet area.
- Mach number There is a direct proportionality between Mach number and texturing. The higher the Mach number, the stronger the impact and the more intense the texturing.
- Th . vor: thermal pretreatment, possibly only with yarn heating or with
- G.mech . Yarn treatment with the mechanical effect of a compressed air flow (supersonic flow).
- the yarn tension is established on the textured yarn 1 06 between the texturing nozzle (TD) and a delivery unit LW2.
- thermal treatment has now been carried out on the yarn, which is under tension.
- the yarn was heated to approx. 1 80 ° C.
- the thermal post-treatment described has a fixing and a shrinking effect on the textured yarn, thereby supporting the texturing.
- the thermal pretreatment also has a positive effect on the texturing process.
- a combinatorial effect between shrinkage and yarn opening in the section between the air injection point in the yarn channel and the first section of the conical widening, in the area of the supersonic speed, may be the cause of the success here.
- the stiffness is reduced by heating the yarn, so that the prerequisite for loop formation in the textile process is improved.
- tests with both hotplate and hotpin as heat sources were successfully completed. It may also help that the thermal pretreatment of the yarn avoids a negative cooling effect due to the air expansion in the texturing nozzle, and therefore the texturing of the warmed yarn is improved. With the very high transport speed, part of the heat in the yarn itself is retained up to the area of the loop formation.
- the additional thermal process steps are preferably separated locally or carried out shortly or immediately one after the other on the running yarn.
- the procedural interventions are not this way isolated, but are combined in a community of interests between two suppliers. This means that the yarn is only held at the beginning and at the end, in between there is both mechanical air intervention and thermal intervention.
- the thermal treatment is carried out on the tension in the filaments or in the yarn, which is still mechanically generated by the compressed air - 7 -
- FIG. 2 gives an overview in relation to the yarn tension (Gsp) and the production speed.
- Gsp yarn tension
- the result is shown with a T 31 1 nozzle, the yarn being heat treated with T31 1 + Th.
- the dash-dotted lines T31 1 + Th are only the result of touch tests.
- a nozzle S31 5 is used with an acceleration channel for Mach> 2.
- the air pressure used for the texturing is not shown in the two curves.
- the dash-dotted curve S 31 5 + Th shows above all the great influence of the heat. Since there are a large number of yarn qualities and yarn titers, it was not yet possible to determine the corresponding relationships exactly. According to textile technology experience, this is only possible in actual production use. However, FIG. 2 clearly shows the stages in the increase in performance through the various combinations.
- a PA 78f51, Core 10%, Effect 30% and a pressure of 9 bar were used as reference material.
- FIGS. 3a to 3e show the typical solutions of the prior art, with a correspondingly known symbol representation, examples of textured yarns being shown in FIG. 3d and a classic texturing nozzle being shown in FIG. 3e.
- Figure 3a shows schematically the known single or parallel processing of FOY yarn.
- Figure 3b the parallel processing of FOY and POY yarn.
- Figure 3c the processing of POY yarn with core and fancy yarn.
- the nozzle shown is a T 31 1 nozzle.
- FIG. 4 shows schematically the use of the new solution for texturing, corresponding to FIG. 3.
- the so-called hotplates H.plate
- the entire air refinement stage is designated LvSt in accordance with FIG. 1 in FIG. 4.
- FIG. 4 shows both a thermal pretreatment 1 20 and a thermal post-treatment 1 21 with the most important process data, air pressure, temperature and yarn speeds.
- H.plate means hot plate
- H.pin means hot pin.
- a yarn moistener HemaJet 1 23 is arranged in front of the texturing nozzle 101.
- the yarn is usually warped by a few percent (1 - 2%) or subjected to a stretching process.
- the yarn is then passed over another heater 1 22, which can now also be a steam chamber. If hot steam is used for thermal treatment at one point, it may be advisable for economic reasons, the other heating points also with hot steam - 8th -
- the table shows the yarn speeds at the marked supplying plants (W) as examples
- FIGS. 5a to 5d show the use of the so-called heated and driven godets for the thermal treatment with some important application possibilities.
- the temperature in the godet shows whether it is a heated position.
- a hotplate or a continuous steam chamber according to the invention can also be used in each case.
- FIG. 6 diagrammatically illustrates the areas of speed increase very roughly, the possible increase in production speed being shown in any case for the identical text quality.
- the blocks shown represent a different combination for the texturing process from bottom to top. In the upper half of the figure, dispositives corresponding to FIGS. 1, 4 and 5 were used, with the increase in performance or production speed achieved, while maintaining a specific, predetermined yarn quality.
- Block 500 shows the prior art with a texturing nozzle T 31 1 according to the figure
- Block 150 shows a texturing nozzle S 31 5. Tests have shown that with an additional thermal process, block 1 50 is still possible with a nozzle T31 1. This is indicated by a dash-dotted arrow. Block 100 also shows a set heater. Block 250 additionally shows a thermal aftertreatment (FIG. 5a) with 10-1 2 bar and with hot plate C / E / ATY; SET. Block 200 additionally shows a thermal pretreatment (FIG. 5d) with 1 2 - 14 bar with hot plate C / E / ATY; SET. The performance increase according to blocks 250 and 200 could only be achieved with constant quality with a texturing nozzle according to WO97 / 30200, i.e. with more than Mach 2 in the acceleration channel. Block 250 requires the higher pressure and heat treatment. Block 200 requires all of the proposed measures. Block 1 50 can optionally be achieved with a T 31 1 nozzle and thermal treatment.
- the invention further relates to the use of at least one or two heat treatments before and / or after a texturing nozzle with Mach> 2 in the acceleration channel
