Definitions

  • the present invention relates to a stretchable fabric having first and second warp yarns and first and second weft yarns.
  • the invention has for its object to propose a tissue in which the said and known from the prior art disadvantages are avoided or at least greatly reduced.
  • This fabric with first and second warp threads and first and second weft threads is characterized in that the first warp threads and the first weft threads form a base fabric and the second warp threads with the second weft threads to the Base fabric adjacent roofing fabric, wherein the second warp threads are also interwoven with the first weft threads and wherein the first warp threads and the second warp threads are arranged so that they lie after stretching of the fabric - alternately - substantially side by side, so always next to a first warp thread a second warp thread comes to rest.
  • the fabric according to the invention there is the advantage that, when the fabric is used to form an airbag, so that the two roof fabrics face each other, an air cushion can be produced on the respective roof fabric in the explosion case, the first application of gas through the airbag gives the generator.
  • the construction of the fabric according to the invention causes the first warp yarns and the first weft yarns to stretch according to the load when the airbag is inflated, with the second warp yarns drawing the second weft yarns into the intermediate spaces created between the first weft yarns due to the elongation of the base fabric.
  • This fabric with first and second warp threads and first and second weft threads is characterized in that the modulus of elasticity of the first warp threads is higher than the modulus of elasticity of the second warp threads, and that the second warp threads are woven with lower warp tension than the first warp threads, and that the first weft threads lie in a ground plane and the second weft threads lie in a roof plane adjacent to the ground plane, wherein the first Warp threads and the second warp threads are arranged so that they are after stretching of the fabric alternately substantially adjacent to each other, so that always comes next to a first warp a second warp.
  • the first warp yarns with a lower modulus of elasticity are stretched more than the second warp yarns with a higher modulus of elasticity, so that the distance between the first weft yarns increases with tensile load on the fabric is compensated by the fact that the previous lying in the roof level second weft thread more or less in the growing gaps between the first weft threads arrange, and thereby the absolute distance between two adjacent weft yarn remains approximately the same.
  • first and second warp and weft threads are spoken repeatedly of first and second warp and weft threads. It is emphasized that not only individual threads are meant, but also multiply laid threads or folded threads, d. H. multiple adjacent threads may be meant. In the formulation z. For example, "a first warp” is meant the word “a” functional and not numerical.
  • the fabric according to the invention can be provided in both solution variants as a piece, for example as a filter part or gas discharge mechanism in an airbag, both ready-made and in "one-piece-woven" air bags (OPW).
  • OHPW "one-piece-woven" air bags
  • the airbag may also be made entirely of such a fabric.
  • first weft threads binding threads
  • first warp threads binding threads
  • second warp threads coupling threads
  • Fig. 1 shows schematically a fabric of the prior art in the unloaded state.
  • Fig. 2 shows schematically the fabric of Fig. 1 in the loaded state, as it takes place in the application of an airbag.
  • Fig. 3 shows schematically an embodiment of the tissue according to the invention in the unloaded state.
  • Fig. 4 shows schematically the tissue of FIG. 3 in the loaded state.
  • Fig. 5 shows schematically another embodiment of the tissue according to the invention in the unloaded state.
  • Fig. 6 shows schematically the tissue of Fig. 5 in the loaded state.
  • FIG. 1 shows greatly enlarged weft threads 3 shown as circles, which of warp threads 1 and 2 in the usual manner of a woven plain weave L 1/1 tissue, wherein the distance between two weft thread is denoted by the reference numeral 6.
  • the upper illustration of FIG. 1 shows a section through a fabric along a first warp thread, in which a first warp thread 1 wraps around weft threads 3.
  • the lower illustration of a detail of a plain weave fabric known from the prior art shows a section through the fabric along a second warp knit fabric. thread 2.
  • the distance 6 between the weft thread 3 (the behavior is the same between warp thread) is due to the design.
  • FIG. 2 now shows the fabric sections according to FIG. 1 in the loaded state, that is to say, for example, in the case of use of the fabric in an airbag, during or after it has been inflated.
  • the application of gas to the airbag (not shown) by a generator (not shown) and / or the immersion of a passenger in the airbag cushion results in a tensile load on the fabric, resulting in a spacing 6 between the weft threads - in FIG for the loaded condition each with a small a provided - remove from each other.
  • the distance 6a is greater than the distance 6, and the weft threads in the position 3a have correspondingly greater distances.
  • FIG. 3 now shows an embodiment of a new fabric in which first weft threads 13 and second weft thread 15 lying above (so-called sealing threads) are arranged.
  • first weft threads 13 and second weft thread 15 lying above are arranged.
  • the weft insertion of the first 13 and second 15 weft threads in conjunction with the warp threads 11 and 14 is again shown in the upper part of FIG.
  • the first weft threads 13, as it were form a base fabric 17, above which a not really "adjacent" roofing fabric 19 is arranged.
  • 3 shows warp threads 12 and 14. As can be clearly seen from FIG.
  • the first warp threads 11 and 12 only undulate around the first weft threads 13, whereas the second warp thread 14, here, as it were in function of a binding thread, forms the first warp thread second weft threads 15 to form a roof fabric 19 to the base fabric 17 binds.
  • the second weft thread 15, so the sealing thread are not here, but rather arranged on the base fabric 17 and form a "roof fabric" 19.
  • the roof fabric 19 is not its own tissue, but a resting on the base fabric 17 fabric area 19, represented by the Weft threads 15 and the second warp threads (binding threads) 14. While the tissue according to FIG. 3 is shown in the unloaded state, FIG. 4 now shows the tissue from FIG. 3 in the loaded state.
  • the first and second warp yarns 11, 12 have stretched under the load extending to the left and right in FIG.
  • the distance between the weft yarns 13a has increased to the dimension 16a, and in the space between the weft yarns 13a, the second weft yarns 15a (sealing yarns) are drawn into the interstices 16a by the binding yarns (second warp yarns 14a). hereby It is possible to keep the gap between the threads constant and thus to keep the air permeability through the tissue even in the load state almost constant.
  • the running length of the second warp thread 14 (binding thread) is selected to be greater than in the variant shown in FIG. 3, then, when the fabric is loaded analogously to the representation according to FIG. 4, a distance 16b which is greater than the distance 16 according to FIG 3. In the woven construction according to Fig. 3, the distance between the fabric layers 17 and 19 would then be greater. Conversely, you could make the distance between the fabric layers 17 and 19 smaller, which would lead to that under load of the fabric analogous to FIG. 4, the distance 16b would be smaller than the distance 16 of FIG. 3 and thus the air permeability with increasing load would be reduced.
  • Fig. 5 shows a second embodiment of a fabric according to the invention in the unloaded state, with similar behavior as in the first embodiment, but without separate binding and sealing thread.
  • two different yarn materials are used in the warp, namely first warp yarns 21 and second warp yarns 24, the second warp yarns 24 having a relation to the modulus of elasticity of the first warp yarns 21 have higher modulus of elasticity.
  • the second warp threads 24 are interwoven with a lower warp tension than the first warp threads 21.
  • the fabric layer results in such a way that the first weft threads 23 are located in a ground plane 27 and the second weft threads 25 are located in a roof level 29.
  • the first warp yarns 21 with a lower modulus of elasticity compared to the second warp yarns 24 are presented with a warp tension for fabric production, and the second warp yarns 24 with an modulus of elasticity which is higher than the modulus of elasticity of the first warp yarns 21 are provided with an im Compared to the first warp threads 21 submitted lower warp tension.
  • FIG. 6 now shows the tissue according to FIG. 5 in the loaded state.
  • the first warp yarns 21a with a lower modulus of elasticity are stretched more than the second warp yarns 24a with a higher modulus of elasticity, so that the increasing distance (26 becomes 26a) between the first weft yarns 23a under tensile load the fabric is compensated by the fact that the previously overlying weft thread 25 depending on the load more or less in the increasing gaps 26a and arrange the absolute distance 28 between two adjacent weft yarn 23 a, 25 a remains the same.
  • second weft threads due to the different material elongation capacity of the warp threads in the loaded state, can be lifted out of the plane of the first weft threads.
  • the distance can also be increased or reduced compared to the relieved tissue Fig. 5.
  • the construction according to the invention allows the air permeability to increase disproportionately when weaving a fabric similar to the fabric of Fig. 6, that is, with the same undulation of the warp yarns 21 and 24, now in the unloaded state.
  • the second weft yarns due to different material elongation (the material elongation of the second warp 24, 24a is higher and the material extensibility of the first warp 21, 21a is lower) are lifted out of the plane of the first weft yarns 23 in the loaded state (analogous to the representation of FIG. 5, but with an even greater distance between the levels 27 and 29, but in the loaded Status).
  • a fabric in which the course of the expansion curve is set individually, which is characterized in that it in predetermined areas warp threads and weft threads with selectively selected parameters such as moduli E, or in a specifically selected sequence having.
  • other technical parameters such as, for example, the course of the expansion curve can be set individually, which subsequently also influences, for example, the unfolding behavior of the air sacs by more or less or individually expanding tissue sections.
  • these intelligent tissue can be used to independently adjust the tissue parameters, which are today dependent on one another, independently of one another.
