Definitions

  • the invention relates to a process for the production of highly dense tissues a water jet loom.
  • tissue is looser at the edges than in the rest Tissue. Due to the loose fabric edges, such fabrics can only be continue to process with difficulty, as the edges are not under the same tension can be held like the residual tissue.
  • the tissue manufacturer speaks from the fluttering of fabric edges (slobby selvedges). This flutter has a special effect ders when unwinding or wrapping the tissue. The fluttering of the fabric edges The more the fabric is made, the more pronounced it becomes. To this flutter Usually, high dense tissue in a width of not more than 1.6 m. Especially from the manufacturers of airbags but tissue widths of at least 1.7 m, in particular of 2 m desired since then the blank of the fabric sections required for the production of an airbag can be done with minimal waste.
  • Object of the present invention is a method of the aforementioned Art to provide, in which the disadvantages described above, at least are reduced.
  • the weaving method should be designed such that the fabric produced easier to handle during subsequent processing is trained.
  • the thread numbers mentioned here are especially valid for plain weave and for other weaves adjusted accordingly.
  • a common factor for these settings is the Kappa factor (cover factor).
  • the inventive method succeeds particularly well when over the entire Width of the warp the distance between adjacent threads including the holding and leno threads is the same size.
  • the distance between two different groups of threads the same size as the distance between adjacent threads of the same group.
  • the method according to the invention succeeds excellently when twisted as holding threads Threads are selected.
  • Threads are selected.
  • those are selected which are 200 to 700 turns per Meter have.
  • twined as twine twofold Threads are selected.
  • Twoftwire threads are those threads in which first a multifilament yarn twisted and then two or more such twisted Multifilament yarns in turn be twisted together.
  • Even with the second Verzwirnung it is favorable, if the twisted multifilament yarns with 200 to 700 Turns per meter are twisted together. For this it is recommended that the twist of the twisted multifilament yarns in the opposite direction to the Twisting of the multifilament yarns takes place.
  • the method according to the invention succeeds particularly well when such as holding threads be selected, which is a thread-thread friction between weft and Holding thread from 20 to 70 cN.
  • the thread-thread friction is measured in the following way:
  • the thread guide is shown in the figure.
  • the one thread F1 solid Line
  • the second Thread F2 (drawn interrupted) is also weighted G2 of 10 cN (free hanging) coming from the left over the roll 1 out.
  • thread F2 Pass four times behind thread F1 to the right and back to thread F1 led left, resulting in 3.5 entanglements.
  • the thread F2 is under the role of 2 and the role 3 to take-up reel 6 and there like thread F1 attached. For the threads F1 and F2 such a length is chosen that the weights Hang G1 and G2 about 1 meter below the measuring device.
  • the motor (not shown) to the roller 6 is now turned on. After 2 - 3 min runtime to align the threads of the thread F1 is in the thread tension meter inserted.
  • the measured values are displayed with the F-Meter R-1188 and on one Recorder type SE 120 (from ABB Goerz AG) recorded.
  • the determined force is given as a measure of the thread-thread friction.
  • the separation welding takes place in such a way that the Ends of the weft threads in the molten state with those at the edges of the Warp arranged threads warp.
  • This separation welding can be so be carried out, that also the hot separating member adjacent edge threads the rest of the warp be transferred to the melt state, so that along the edges of the finished fabric a continuous welding edge arises, the avoidance of the flutter edges described above positive affected.
  • the fabric produced by the method according to the invention differs differ from the usual weaving method on water jet looms fabric produced by the fact that the weft threads on both edges of Tissues are cut off while in the conventional manner Water jet looms produced fabric only at a fabric edge have cut weft threads, while on the opposite edge of the fabric the weft threads protrude slightly out of the fabric.
  • the handle in the edge region at least almost the same as the grip between the edges, for example in the Middle of the fabric track.
  • the fabrics produced according to the invention are excellent for the production of Airbags, parachutes and sailcloths and suitable for all the fields of application, in which requires extremely dense tissue.
  • yarns can be used a total denier of 470 dtex in a density of up to 25 threads per cm in warp and weft direction are woven.
  • Two sets of threads consisting of 40 threads of PA6.6, each on one Were also wound the water jet loom submitted in such a way that they are in Riet the water jet loom respectively connected to the edges of the warp. These yarns acted as Healds and had a total denier of 234 dtex and 68 filaments.
  • the Yarns of the holding threads were twofold twisted threads of construction Z 476 S. 637. This construction is achieved by making a yarn with 34 filaments first in the S direction with 637 turns per meter and then two such twisted yarns in z-direction are twisted with 476 turns per meter.
  • the Holding threads had a hot air shrinkage measured under the same Conditions such as the hot air shrinkage of the yarns of the warp, from 1.8% up.
  • the weft thread used was a multifilament yarn made of PA 6.6 with a total titer of 470 dtex and 72 filaments used.
  • the weft threads had a hot air shrinkage of 8.2%.
  • the thread-thread friction between weft and Holding thread was 47.5 cN.
  • the threads of the warp, the holding thread and the fishing threads were side by side read in the reed of the water jet loom, the Riet 100 Rietlücken per 10 cm exhibited and each 2 threads were pulled into a Rietlücke.
  • the threads were at a tension of 120 cN / tex, the threads the holding threads held at a tension of 123 cN / tex.
  • the fabric made in this way had 21.5 threads per cm in warp and 21.5 Threads per cm in the weft direction.
  • the two edges of the fabric had the same Grasp like the inside of the fabric.
