    • D06B23/06Guiding means for preventing filaments, yarns or threads from sticking together

Definitions

  • the invention relates to a process for the production of partial chains wound on warp beams or partial warp beams or chains of synthetic filament yarns wound on warp beams, which are essentially completely stretched and sized, according to which a family of essentially parallel synthetic filament yarns is used as the starting material and this family of a possibly heated sizing zone is guided and finished there, then passed through a heated predrying zone and predried there, then passed through a heated final drying zone and subjected to final drying there and finally onto slip beams or partial warp beams or Warp beams is wound up, the filaments of the filament yarns of the sheet of the display material not being fully drawn and these filaments in or essentially in the predrying zone together and simultaneously using a roller system assigned to the size zone and a roller system assigned to the final drying zone, these roller systems having different peripheral speeds rotate, be stretched.
  • filament yarn means a yarn made of multiple filaments; the term “filament” includes an endless (continuous) thread-like structure, that is to say a practically unlimited length (cf. DIN 60 000).
  • Partial warps wound on slip trees are those which are used for assembly - to form a warp wound on a warp beam.
  • BE-905 768 a method of the type mentioned is known.
  • BE-905 768 does not provide any information on how uniform partial chains or chains can be produced in all respects with the method described therein.
  • BE-905768 says nothing about how, with the method known from it, the removal of irregularities, such as filament loops, of the filament yarns fed as the starting material, a very uniform stretching of the filaments of the filament yarns, an even distribution of the size on the filament yarns and whose filaments - so that both are practically completely covered by the size - a high uniformity of the filaments in terms of their density - so that completely closed filament yarns are obtained - and a high uniformity of the filament yarns with regard to the parallelism of their filaments can be achieved.
  • the invention has for its object to provide a method of the aforementioned type for the production of partial chains or partial warp chains wound chains or chains of synthetic filament yarns wound on warp beams, with the inexpensive and / or without great effort qualitatively flawless, especially in any Regarding even partial chains or chains can be made; it should be possible to dispense with a thread or thread replacement treatment for the filament yarns before sizing.
  • the filaments of the filament yarns of the batch of the starting material are drawn together and simultaneously in the predrying zone or essentially in the predrying zone.
  • "Essentially in the pre-drying zone” means: in the area between the last rollers assigned to the size zone and the rollers assigned to the final drying zone.
  • a family of essentially parallel synthetic thermoplastic filament yarns, etc. passed through an optionally heated size zone and finished there.
  • An optionally heated size zone means that the size zone, in particular the size liquid in the size trough, can be heated or unheated;
  • unheated means that the sizing liquid e.g. Has room temperature.
  • a family of essentially parallel synthetic thermoplastic filament yarns is used as the starting material.
  • the filaments in these filament yarns can also be parallel; however, although it is not necessary, the filaments may be interlaced (tangled) in places, for example with the aid of an air nozzle, or they may have been subjected to a twist.
  • the filament yarns used for the purposes of the invention can, for example, consist of polyester, such as polyethylene terephthalate, polyamide, such as polyamide-6 or polyamide-66, polyolefin, such as polyethylene or polypropylene, and also consist of their mixtures or copolymers.
  • the filament yarns can also consist of other synthetic thermoplastic polymers or their modifications.
  • FIG. 1 shows schematically and in section a conventional device for sizing partial chains or chains made of synthetic filament yarns that is suitable for carrying out the method according to the invention.
  • a predetermined number of bobbins with synthetic thermoplastic filament yarn, the filaments of which are not fully drawn, are placed on a conventional bobbin, not shown; the yarns are drawn off from this creel under constant thread tension and arranged in parallel with the aid of a reed, also not shown, after which the sheet of filament yarns thus formed is guided via a roller system 1 rotating at constant speed and a roller 2 to a size trough 3 forming the size zone, which is filled with a sizing liquid.
  • the yarns are then passed through a sizing roller 4 through the sizing liquid and from there via a sizing roller 5 to the nip between the sizing roller 5 and a squeeze roller 6, where the sizing liquid is applied and the excess thereof is squeezed off at the same time.
  • the yarns then form through the predrying zone heated pre-dryer 7 and 8 passed where they are pre-dried; from there the yarns are passed through a final dryer 9 forming the final drying zone, where they are subjected to final drying by being guided over heated drying cylinders 10.
  • the - parallel - filament yarns are guided from the end dryer 9 to a slip beam, partial warp beam or warp beam 11, on which they are wound up.
  • rollers 5 and 6 rotate at a peripheral speed which is lower than that of the drying cylinder 10, whereby the filaments of the filament yarns are stretched together and simultaneously, to be precise between the pair of rollers 5, 6 and the drying cylinders 10, i.e. in the predrying zone or in essential in the pre-drying zone.
  • the method according to the invention can also be carried out in such a way that the filament yarns are not drawn off directly from bobbins placed on a creel, but for example from one tree or several trees.
  • the chains produced by the process according to the invention show excellent running behavior during weaving, and the fabrics produced from these chains have excellent properties with regard to color affinity, color uniformity, strength and elongation properties, tendency to bulge and length increase.
  • 1,492 bobbins with polyamide 66 filament yarn 97.7 dtex f 17 (partially oriented yarn POY), the filaments of which were thus pre-oriented, were placed on a conventional bobbin creel (from Benninger, Switzerland); the filament cross section was round.
  • the tensile strength of the filament yarn was 35.2 cN / tex and the elongation at break was 75%.
  • the yarns were drawn off from the creel at a speed of 312.2 m / min using a draw-off roller system under constant thread tension.
  • the filament yarn group thus formed was passed to a size trough which was filled with a size liquid.
  • the size liquid consisted of an 11% aqueous solution (liquor concentration) of an acrylic size (Sopronyl AR 41 from Rhône-Poulenc, France) and had a temperature of 42 ° C.
  • the yarns were then passed over a roller immersed in the sizing liquid (immersion roller) and from there passed over the sizing roller also immersed in the sizing liquid to the pinch joint between this sizing roller and a squeezing roller.
  • the squeezing pressure between the sizing roller and the squeezing roller - when running - was 6.0 kg / cm2 (6.0 daN / cm2).
  • the size roller and the squeeze roller rotated at a peripheral speed of 312.9 m / min.
  • the - parallel - yarns were then passed through two pre-dryers connected in series, both of which had a temperature of 150 ° C.
  • the predrying zone formed by the two predryers was 11 m long.
  • the family of parallel filament yarns was then passed through a final dryer, the first drying cylinder of which rotated at a peripheral speed which was 31.67% higher than the peripheral speed of the sizing roller and the squeeze roller.
  • the yarns were subjected to final drying by being guided over the five heated drying cylinders of the final dryer.
  • the first four drying cylinders of the final dryer each had a temperature of 135 ° C; the last drying cylinder of the final dryer had a temperature of 110 ° C.
  • the filaments of the filament yarns were stretched in the area between the sizing / squeezing roller and the drying cylinders of the final dryer.
  • the thread tensile forces determined during the implementation of the method according to the invention - measured on the individual filament yarn - were the following:
  • the filament yarns thus sized and drawn had the following properties: Titer: 83.1 dtex (arbitrated) Tear resistance: 41.5 cN / tex Elongation at break: 40% Cooking shrinkage (30 min in boiling water): 7.04% Sizing pad: 4.66%
  • the filament yarns obtained had an almost round yarn cross section and their filament composite was closed. The core and coat arbitration was practically complete.
  • the yarns were drawn off from the creel at a speed of 45.2 m / min with the aid of a draw-off roller system under constant thread tension.
  • the size liquid consisted of a 20 to 21% aqueous solution (liquor concentration) of a polyester size (Gerol PS 25 from Rhône-Poulenc, France) and had a temperature of 74 to 77 ° C.
  • the yarns were then passed over a roller immersed in the sizing liquid (immersion roller) and from there via the sizing roller lightly touching the surface of the sizing liquid to the nip between this sizing roller and a squeezing roller.
  • the squeezing pressure between the sizing roller and the squeezing roller - during the run - was 600 daN (based on the total contact line or area of the two rollers).
