Definitions
- the invention relates to a method for air-blast texturing of continuous filament yarn with an air-jet texturing nozzle with a continuous yarn channel at one end the yarn is fed and at the other end the textured yarn is removed and compressed air is fed into the yarn channel in a central section and in one expanding acceleration channel the blast air jet accelerates to supersonic and the loop yarn with a high transport speed of preferably over 600 m / min is generated, the air blowing texturing line by a delivery unit 1 am Beginning and a delivery plant 2 is limited at the end of the air finishing stage.
- the invention further relates to a yarn finishing device with a texturing section, consisting of a supply plant 1 for the supply of the yarn, one Texturing nozzle and a delivery unit 2 after the texturing nozzle, the Texturing nozzle has a continuous yarn channel, at one end of which Yarn fed, and at the other end the textured yarn discharged and in a middle section of compressed air is fed into the yarn channel and in one a blown air jet with supersonic can be generated by the expanding acceleration channel.
- the invention is based on an air bubble texturing according to WO97 / 30200.
- the finishing of continuous filament yarn has two main tasks. To the One is the textile, made from industrially produced filaments Character and textile properties are given. Second, should the yarn is refined with regard to specific quality characteristics of the end product very often cannot be achieved by products made with natural fibers are. A very important goal for industrially manufactured filaments or the yarns and fabrics produced from it, lies in the processing process to optimize. Optimizing means here. Conservation or increase certain quality criteria and lower production costs. production costs can be lowered in various ways. The most obvious way is the increase in throughput speed in a given production plant. A second possibility lies in procedural interventions that are not necessarily include an increase in throughput speed, but certain Ensure quality criteria even at high yarn throughput speeds.
- the textile industry is one of the, especially in the case of continuous filaments most complex branches of industry, from the raw material to the finished surface product several independent industries and trades are involved. There is none the branches completely autonomous, rather it is a processing chain at each process change in one stage, the subsequent or possibly previous ones Levels can affect. But it is always open whether the end user does Product accepted or rejected after changes often through new process techniques in terms of quality characteristics. For some product sectors, In the filament spinning mill, in particular, the finishing of yarn is done using yarn finishing nozzles the most important section. The structural change from plain yarn to A textured loop yarn is caused solely by mechanical air forces. This creates an air flow in the supersonic area, as in the beginning mentioned WO97 / 30200 is shown.
- DE-OS 38 23 538 shows a process for the production of PBT carpet yarn. It is a compression crimp, which is an integrated process within a Spin-draw texturing with transport speeds of over 1800 m / min is carried out. With the crimp, the yarn deformation becomes thermal supports this, in contrast to the air bubble texturing, in which the Air forces alone cause the deformation.
- the US.PS 40 40 154 shows another example of a compression crimp with Use of hot steam.
- the compression crimp takes place inside the cylindrical Channel start.
- the yarn leaves the channel without tension. This is in conflict to the actual texturing, in which the generation of tension on the yarn on Exit from the nozzle is a measure of the quality of the texturing. texturing was previously often understood in the most general sense and not as a technical term.
- the invention has now been given the task of processing the Optimize the production of a loop yarn. Part of the job for that In particular, the process was without higher yarn transport speeds Allow loss of quality.
- the method according to the invention is characterized in that the yarn between delivery plant 1 and delivery plant 2 by an upstream and / or downstream Yarn heating device is heated in such a way that between delivery unit 1 and Delivery unit 2 both the mechanical air intervention and the thermal intervention takes place.
- the production speed is still completely open upwards. It was also interesting to observe that only the thermal action before and / or after the texturing nozzle already showed an increase in performance with all nozzles with M ⁇ 2.
- the new invention has shown that there are causal connections between the increase the pressure, the Mach number, the yarn transport speed and the thermal Influence. With the effect of heat before texturing the Stiffness of the individual filaments reduced. The filaments can be warm Bend the state more easily with less energy, which is the main reason for this portion. With the effect of heat after texturing, the structural change in the Texturing carried out more perfectly.
- the invention further relates to a yarn finishing device and is thereby characterized that between the two supplying plants, after the texturing nozzle, before the delivery unit 2 and / or before the texturing nozzle, after the delivery unit 1 one Yarn heater is arranged.
- a yarn finishing device for particularly advantageous embodiments of the Yarn finishing device is referred to claims 8 to 10.
- the invention further relates to the use of a heat treatment before and / or after a texturing nozzle with Mach> 2 in the acceleration channel.
- the production speed could increase with additional thermal treatment at 1500 m / min. without breakdown of texturing and without slagging be increased, the limit being given by the existing test facility was.
- the best texturing qualities could go far beyond the product speed 800 m / min. be achieved.
- the thermal pretreatment has likewise 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 extension, in the area of supersonic speed, cause of success.
- the stiffness is reduced, so the prerequisite for loop formation in the texturing process is improved.
- thermal Pretreatment of the yarn has a negative cooling effect due to the air expansion in the texturing nozzle, and therefore texturing when the yarn is heated be improved.
- FIG. 2 gives an overview of the yarn tension (Gsp) and the production speed.
- Gsp yarn tension
- T 311 + Th the yarn was heat treated with T311 + Th.
- the dash-dotted Lines T311 + Th are only the result of touch attempts.
- an S315 nozzle is used with an acceleration channel for Mach> 2.
- the air pressure used for the texturing is not entered in the two curves.
- the dash-dotted curve S 316 + Th shows above all the great influence the effect of heat. Since there are a variety of yarn qualities and yarn titers, it was not yet possible to determine the corresponding relations exactly. After the Experience in textile technology is only possible in actual production use.
- FIG. 2 clearly shows the stages of the increase in performance through the different combinations.
- a PA 78f51, Core 10%, effect 30% and a pressure of 9 bar are used.
- FIGS 3a to 3e show the typical solutions of the prior art with in accordance with the known symbol representation, wherein in the figure 3d examples of textured yarns and with the figure 3e reproduced a classic texturing nozzle is.
