  • a fabric can be produced, for example, with a weaving machine described in DE 103 07 489 B3 (Dornier).
  • Such a woven fabric is due to its leno bindings with significantly increased slip resistance (Kammausziehkraft) produced, especially for thinner fabrics, such as dtex 235.
  • slip resistance Kammausziehkraft
  • the tear propagation force is significantly improved on the one hand by the possible lower thread density and on the other hand by the leno weave itself.
  • this is characterized by leno weaves and plain weaves, the ratio of leno weaves to plain weaves is less than 1. This has the particular advantage that the combination of the plain weaves as the densest possible bonds and the leno weaves as the strongest bonds allows ideal conditions for high slip resistance and tear propagation force at the same time realizable air permeability.
  • the fabric is designed so that the ratio of double or multiple weft yarns to single weft yarns is less than 1.
  • the slip resistance or comb extraction force can be further improved. Tissue stability is also increasing.
  • a textile fabric with a ratio of leno weaves to linen weaves of 1/7 has proven to be particularly advantageous.
  • a woven fabric which is characterized by, consisting of upright and regular weft, fabric grid, which is without Ondulation that of leno threads, which have a lower titer than the uprights and weft , is held on top of each other.
  • This is particularly advantageous in the case of so-called coating base fabric, which is produced with reduced thread density, which due to the construction according to the invention has an increased slip resistance with a smaller design strain.
  • a coated conventional canvas fabric with a thread titer of, for example woven dtex 235, due to the ondulation has a 5 - 10% design strain.
  • a textile fabric according to the invention which may also be called a hybrid leno fabric, has practically only the material expansion of the fabric grid resulting from the stiffening and weft threads. The fabric grid lies on top of each other without undulation, held in place by the leno threads.
  • the sheet according to the invention is characterized by additional carbonizable weft threads, in particular viscose threads whose titer is higher than the titre of the regular weft threads.
  • additional carbonizable weft threads in particular viscose threads whose titer is higher than the titre of the regular weft threads.
  • inventive fabrics have the peculiarity that the steherund canvas binding threads have the same denier, in particular dtex 235, and the leno threads a lower denier, in particular dtex 110.
  • a fabric according to the invention with carbonizable weft threads having a denier of 1220 dtex is particularly advantageous in that this construction permits a special surface suitable for carbonization with simultaneous symmetry of the supporting basic structure of the fabric.
  • this is characterized by additional weft threads which have additional heat-protection properties (eg by using carbonizable threads).
  • this is characterized by a basis weight of less than 180g / m 2 , a thread density warp / weft less / equal to 220/220 / dm, a maximum tensile force greater than / equal to 2500N / 5cm and a Kammausziehkraft greater / equal 200N.
  • the fabric grid is a symmetrical fabric grid. This can positively influence the carrier function during coating and / or lamination.
  • an airbag for passenger restraint systems for vehicles by water, by land, in the air and in space which is produced by a fabric according to one of the above-described advantageous embodiments of a woven textile fabric according to the invention.
  • Fig. 1 shows a schematic view of an embodiment of a sheet according to the invention as a simple Dreheripstop.
  • Fig. 2 shows a schematic view of another exemplary embodiment of the sheet according to the invention as a reinforced Dreherripstop.
  • Fig. 3 shows a schematic view of a hybrid rotary fabric according to the invention.
  • Fig. 4 shows a schematic view of the fabric of FIG. 3 according to the section
  • FIG. 5 shows a schematic view of a carbon fiber hybrid hybrid fabric with embroidery stitching in section.
  • Fig. 1 shows a simple Dreherripstopgewebe with Steherfäden 1, leno thread 2 and weft threads 3.
  • the exemplary fabric shown here according to the invention has the following thread sequence: A ground thread 1 from a (not shown) warp beam I, a leno thread of a warp beam (not shown) II, Rietlücke 5, seven warp threads as plain weave of a (not shown) warp beam II (area 4) and so on.
  • the shot sequence is 1/1 linear.
  • the uprights and canvas binding threads have the same denier, e.g. B. dtex 235.
  • a leno warp 2 shown here, hardened on the warp beam II (same incorporation) has a lower titer, z. B. dtex 110.
  • the weft thread 3 and the canvas chain of the area 4 have dtex 235.
  • the ground thread 1 is exclusively in the shallow fold, while the leno thread 2 mutually bonds in the high shed.
  • the ratio of leno weaves to plain weaves is less than 1 and here exactly 1/7. Due to the configuration of the sheet according to the invention described here, the slip resistance (Kammausziehkraft) is improved.
  • the weft threads on each eighth warp thread 1 (standing thread) are additionally bound by the leno thread 2.
  • the leno threads 2 stop the shifting of the plain weave warp threads (area 4). The tear propagation force in the weft direction is improved by the integrated leno threads 2.
  • Fig. 2 shows schematically greatly simplified a reinforced Dreherripstopgewebe.
  • the reinforced ripstop shown here is proposed. It can be seen again on both sides of the representation of the ground thread 1, which is fixed by the leno thread 2.
  • the sheet shown here has a reporting double weft 13, which is woven rapportwise in the canvas base fabric 14.
  • the yarn sequence shown here and the yarn thicknesses correspond to the conditions according to the fabric of FIG. 1.
  • the firing sequence is six times 1/1-shot and once 2/1-shot (double shot). By this construction, the tear propagation force in the warp direction is further improved by the double shots.
  • the Kammausziehkraft is the same according to the embodiment of FIG. 1 assume.
  • FIG. 3 shows a hybrid leno fabric designed as a coating base fabric with reduced thread density, non-slip and with a lower design strain. It is a symmetrical fabric grid in Halbfiteritati. In cases where the heat capacity of an uncoated fabric, which is necessarily thin because of the small installation space available, is insufficient, a coating must be carried out, for example, with silicone.
  • a coated conventional linen fabric e.g. For example, in dtex 235, without ondulation, there is a 5 - 10% eternal design strain. Triggered by the airbag internal pressure in the event of a crash, the design strain will first perforate the coating, and the gas outflow will be unplanned and start earlier.
  • a shown in Fig. 3 hybrid leno fabric has practically only the material expansion of the resulting fabric from standing and weft fabric grid. It can be seen in Fig. 3 ground thread 21, which are fixed by leno thread 22 with the involvement of weft yarns 23.
  • Fig. 4 shows the sheet according to Fig. 3 according to section A-B.
  • the ground threads 21 and the weft threads 23 form a fabric grid, which without Matterdulation, held by the leno threads 22 against sliding over each other.
  • the fabric construction is as follows:
  • the ground yarns 21 are supplied from a warp beam I (not shown), for example, in the thickness dtex 235, while the leno threads 22 are supplied from a warp beam II (not shown) in the thickness dtex 110.
  • the weft yarns 23 are supplied in a thickness of dtex 235.
  • FIG. 1 In the embodiment of a fabric according to FIG.
  • the thread density in warp and weft can be influenced by the ratio of the yarn thicknesses of ground thread 21 to leno thread 22, wherein the symmetry of the fabric must always be taken into account.
  • Another parameter here is the warp tension, which can be set differently in terms of process by the two-dimensional weaving (warp beam I and warp beam II).
  • the lowest thread density results when a standing thread and a leno thread have the same titer. In this case (not shown here) results in a classic leno fabric, which in the warp direction has an ondulation (incorporation), whereas the weft straight, d. H. incorporates without or with minimal ondulation.
  • FIG. 5 shows, by way of example, a hybrid leno fabric with embroidery weft suitable for carbonization (DE 101 15 890 A1, BST Safety Textiles). It is to be carried out according to the invention, a dense Hygienwebe mit Karbonisier phenomenon eg for the purpose of implementing the invention according to EP 0 893 311 A3 (TRW) for producing a heat-resistant airbag fabric.
  • TRW EP 0 893 311 A3
  • the sectional construction according to FIG. 5 is intended to illustrate how a special surface suitable for carbonization can be achieved with simultaneous symmetry of the supporting basic construction of the fabric.
