Definitions

  • This invention relates to a fluidized unsized synthetic filament yarn for the manufacture of engineering fabrics having a total titer of 100 to 1500 dtex. Furthermore, the invention is directed to a technical fabric containing such synthetic filament yarns (also referred to as yarns hereinafter) and to a process for producing these yarns.
  • Yarns suitable for use in fabric making are usually sizing or twisted.
  • twisting and the sizing considerably increase the production costs of the yarns and thus also of the fabrics.
  • the sizing must be removed after fabric production, so the fabric must be desized. This process is problematic from an economic and ecological point of view, since not only are costs to be spent for the desizing, but, moreover, additional costs are incurred for the treatment of the decontamination baths, which is absolutely necessary for ecological reasons.
  • twisting or twisting which costs approximately the same amount as sizing, eliminates the desizing costs, there is another disadvantage here, since twisted or twisted yarns are known to be "more granular" fabrics than untwisted or untwisted yarns result.
  • swirling of the individual filaments may be an alternative to sizing.
  • Tangelung is a common practice in the chemical fiber industry.
  • Intermingeln is common.
  • the opening length and also the stability of the swirl points are controlled by a precise matching of the geometry of the tangle nozzle, the tension and the speed when entering the tangle nozzle and the amount of air introduced. These process conditions for the Tangein depend on the Gamtiter and on the preparation applied to the yarn and thus have to be adapted to these parameters.
  • the opening length ie the average length between two Verwirbelungsticianen or Tangelknoten takes place, for example, using a so-called Rothschild Automatic Yarn Entanglement Tester, Type R-2070.
  • the yarn to be tested is biased by two hysteresis brakes such that the thread tension at the entrance of the actual measuring section is 10 cN.
  • the yarn is detected and spread by two yarn guides, after which a measuring needle pierces the yarn.
  • a measurement signal is triggered, the meanwhile traversed yarn length determined by an electronic counting relay and registered in a storage plant. After that, the yarn is automatically advanced and the measurement cycle starts again.
  • the term "free of tie knots" or “virtually no tie knots” is to be understood as meaning that no opening lengths can be satisfactorily increased in a measurement of the opening lengths of the swirled yarn, for example with the Rothschild tester described above.
  • the entangled yarns are yarns of polyamide or polyester filaments. Yarns made predominantly of polyethylene terephthalate are very particularly preferred.
  • the further component, containing a polyester wax preferably has a kinematic viscosity at 70 0 C from 2500 to 3000 cSt.
  • the further component containing a polyester wax is an additive which, in spite of a very low application rate of from 0.1 to 0.5% by weight .-% causes a very excellent behavior of the game so treated, which means that you can do without the described in the prior art very stable Verwirbelungs, or elaborate sizing applications. This phenomenon was in no way derivable from the prior art.
  • the additional or further component may contain other ingredients, e.g. so-called EO-PO adducts, but also polybutanediols are mentioned.
  • Waxing is to be understood as meaning in this case water-insoluble compounds which are solid at room temperature.
  • Preferred waxes are those based on isophthalic acid esterified with ethylene glycol, diethylene glycol and / or triethylene glycols or mixtures thereof.
  • Another preparation which has proven particularly effective is a preparation sold under the trade name DELION F-6120 by TAKEMOTO FAT & OIL COMPANY.
  • the properties of the game according to the invention as a weft yarn can be investigated with the aid of the so-called air index tester (Air Index Tester) from the company Picanol nv leper (Belgium).
  • Air Index Tester is an independent testing device that measures, inter alia, the speed of a weft yarn during interweaving by means of air nozzles.
  • the tester simulates the shot entry, thereby measuring the speed (mean and deviation) of the yarn as it enters the air jet loom.
  • the test result is called the air index.
  • the test runs fully automatically, whereby a test report is generated via the control computer of the test device.
  • those determined for the yarn Test results are compared with the test data of similar yarns.
  • the air index tester can provide a further characteristic in the evaluation of weft yarns, in particular, which resistance a yarn opposes the air acting on it. The higher the thread closing, the lower the resistance to the air and the lower the measured velocity and thus the air index.
  • the figure illustrates schematically how a simulation of the weft insertion on air jet looms with the help of the air deoxyzer can be adjusted.
  • the yarn is wound on a cross-wound bobbin (1) by a feeder (2) and prepared for weft insertion. To enable a uniform yarn withdrawal, a defined number of turns over a constant diameter is necessary. Regardless of the type and size of the bobbin, the feeder unit prepares a number of turns adapted to the yarn count for a secure weft insertion.
  • the force to transfer the thread is achieved by a main nozzle (3) by means of air pressure.
  • the Air Index Tester consists of a calibrated feeder, a calibrated main nozzle with pressure regulation system and a computer with the appropriate software package. The software activates the necessary control systems, controls the measuring program and supplies the characteristic air index LI and its variation CV LI.
  • the characteristic air index LI [m / s] allows on the one hand statements about the maximum possible
  • the second parameter is the variation of the air index CV LI [%]. It indicates the percentage velocity variation within the yarn sample.
  • the air index tester and the measuring principle on which it is based is known to the person skilled in the art or the subject of a series of publications.
  • the invention is further directed to a technical fabric consisting of a fluidized synthetic filament yarn having a total denier of 100 to 1500 dtex, said yarn being virtually free of tangeline knots prior to weaving, and additionally 0.1 to 0.5% by weight of a component based on a polyester resin.
  • Such fabrics are characterized by an excellent appearance and an equally good coatability.
  • the invention is also directed to a process for producing swirled unsized synthetic filament yarns having a total denier of 100 to 1500 dtex, characterized in that in a first step, the filaments are intermingled with each other so that virtually no Tangelknoten form in the yarn, and in a further step, the yarn thus fluidized is loaded with from 0.1 to 0.5% by weight of a further component comprising a polyester wax.
  • the additional or further component may contain other ingredients, e.g. so-called EO-PO adducts, but also polybutanediols are mentioned.
  • Waxing is to be understood as meaning in this case water-insoluble compounds which are solid at room temperature.
  • Preferred waxes are those based on isophthalic acid esterified with ethylene glycol, diethylene glycol and / or triethylene glycol or mixtures thereof.
  • the further component comprising a polyester wax has a kinematic viscosity at 70 ° C. of 2500 to 3000 cSt.
  • a particularly effective component has proved to be a preparation which is sold under the trade name DELION F-6120 by TAKEMOTO FAT & OIL COMPANY.
  • the turbulence is preferably carried out with known Verwirbelungsdüsen.
  • Such nozzles are known, for example, as so-called interlacing jets from Heberlein Fiber Technology Inc.
  • Tangelriets in which simultaneously several yarns are swirled side by side.
  • Tangelriets are also known. They are characterized by the fact that the yarns to be twisted are guided side by side through corresponding grooves and are thereby blown from nozzles with compressed air. The air can thereby be blown in the direction of the yarns to be swirled (conveying) or against the direction of the yarns to be swirled (braking). As blowing pressure of the air, a range of about 0.5 to about 2.0 bar has been found to be suitable.
  • still pulleys can be mounted before and / or behind the Tangelriet, which further facilitates the Verwirbelungsrea.
  • the application of the further component comprising a polyester wax preferably takes place after the swirling step, for example by guiding the swirled yarns over wetting rolls.
  • the application of the further components comprising a polyester wax takes place in the form of a suspension of this component in water.
  • a suitable concentration therefor a range of about 15 to about 35 wt .-% of the component in water, preferably about 25 wt .-%, and a temperature range of the application of about 25 0 C to about 40 0 C has proven.
  • 45 0 C occurs in an emulsion of the particularly preferred further component, the DELION F-6120 from the TAKEMOTO FAT & OIL COMPANY, in water to a surprising increase in viscosity to about 55 0 C. Possibly this anomaly is the viscosity of the aqueous emulsions Of the particularly preferred DELION F-6120 a reason for its effectiveness in terms of good yarn and fabric properties.
  • the further component comprising a polyester wax at 70 0 C has a kinematic viscosity of 2500 to 3000 cSt.
  • the process according to the invention is also possible with other synthetic yarns, it is preferred if the yarns to be treated consist of polyamide or polyester filaments. Most preferably, polyethylene terephthalate is the major constituent, i. the yarns are over 90% obtained from this polymer.
  • Three filament yarns (A, B and C) of polyethylene terephthalate were prepared. All yarns had a total denier of 1100 dtex and a filament count of 210 individual filaments each. The yarn tenacity was about 80 N, with an elongation at break of about 19%. Yarn A was used without knitting, Yarn B was dangled normally and had a mean opening length of 28 cm as measured by the Rothschild tester. Yarn C was an inventive, only vortex, yarn with an apparent average opening length (also Rothschild) of at least 90 cm. In addition, yarn C still contained 0.2% by weight of another component, in this case the DELION F-6120, as an order.
  • the three yarns were tested on the Air Index Tester. While yarns A and B had an air index (LI) of about 40 m / s at a CV LI of about 2%, the LI of yarn C of the invention was only 36 m / s with a CV LI of 2.7%.
  • LI air index
  • the fabric produced by means of the yarn according to the invention was characterized by very good uniformity and excellent coating power.
