Definitions

  • the present invention relates to a double fabric, a method for producing the double fabric, an inflatable structure comprising the double fabric and the use of the double fabric and the structure.
  • Double weave is a form of multiple weave. They consist of two superimposed fabrics, which are selectively connected to each other during weaving. Double fabric, also known as double wall fabric, spacer fabric or two-layer fabric, are generally known and are used in a variety of ways.
  • a specific form of such a double fabric is 2-wall fabric, i.e. spacer fabric with two fabric layers that are connected to one another by a large number of spacer threads.
  • the sides of such 2-wall fabrics are always open after the fabric has been manufactured, i.e. the two fabric layers are not connected by a common edge.
  • the edges of the fabric layers can be joined together through assembly - and thus through an additional work step, whereby a gas pressure can be built up, for example, through a built-in valve. This creates inflated spacer fabrics, with a large number of spacer threads being arranged vertically to the two fabric layers.
  • Such inflated spacer fabrics with spacer threads arranged vertically to the spacer fabric layers can be produced cost-effectively and are, for example, well suited for upholstery.
  • the individual spacer fabric layers connected to the spacer threads can simply be shifted laterally to the opposite spacer fabric layer, they do not give the inflated spacer fabric sufficient stability for many applications. Therefore, such are sufficient Fabric no static requirements.
  • the distance between the two fabric layers is limited, which means that they can be used in a less versatile manner.
  • the JP S41 13588 Y1 discloses a double fabric comprising an upper fabric and a lower fabric comprising a plurality of warp threads and a plurality of weft threads (1, 2, 3, 4).
  • the weft threads 1 and 4 - coming from the edge - are initially interwoven with warp threads of the upper fabric (first segment A), are then led to the lower fabric where they are interwoven with warp threads of the lower fabric (segment C) and then they become the upper again Fabrics where they are interwoven with other warp threads of the upper fabric (second segment A).
  • weft threads 2 and 3 are first interwoven with warp threads of the lower fabric (first segment A '), then woven with warp threads of the upper fabric (segment C') and finally they are interwoven with other warp threads of the lower fabric (second segment A ') .
  • This procedure can be repeated many times.
  • the weft threads connect warp threads in at least 3 segments, ie ACA, respectively.
  • the disclosed double weave cannot be compressed flat. It is also not suitable for being laminated with a flat component, which makes it unsuitable as a building structure.
  • the object of the present invention is therefore to provide a fabric with an inner hollow structure and an outer common edge, which can be produced in a simple manner in one weaving process.
  • a gas such as air
  • the fabric should be easy to manufacture and - especially after lateral lamination - be able to withstand high physical requirements. If the fabric and the structure contain little or no gas, they should be storable and transportable in a small space and also have a low weight.
