Definitions

• the invention relates to a method with which a partially at least two-ply fabric can be produced in a coherent weaving process.
• the invention also relates to an at least sectionally two-layered fabric formed by the method as well as uses of such a fabric.
• the invention has for its object to provide a first method, with which a fabric can be produced, which is partially at least two layers, that is, two non-mutually bonded fabric layers, and in the partially single-layer, partially at least two-ply tissue regions can be formed, the are completely unyielding, teilnachgiebig or very compliant, so that such a fabric can be used for a variety of purposes.
• a fabric is to be produced which is particularly well suited for sitting or lying areas and forms pleasant sitting or reclining properties.
• the tissue should be highly resilient and be able to be adjusted in areas to a wide variety of requirements, for example weight loads, sinking depths and the like.
• the process for the production of a fabric, at least two-ply fabric according to claim 1 proceeds in a coherent weaving process and is characterized by the following process steps:
• a jacquard weaving machine is provided with at least two warp beams, then one of the two warp beams is wound with a first yarn which is substantially inelastic.
• Inelastic yarns according to the invention essentially have an elongation of at most 35-40% and may for example be formed entirely from polyacrylic. But there are others
• the second warp beam is partially wound with a substantially inelastic yarn according to the above definition and partially stretchable with a yarn that has a significantly higher elasticity than the first yarn, in other words by at least 100% of its basic length is stretchable.
• weft thread is substantially inelastic (as defined above "inelastic") and the other weft thread has a high elasticity with respect to the first weft thread, for example a thread as defined above as being substantially highly elastic.
• Such a fabric is suitable, for example, to form an elastically yielding middle fabric layer in the flat-stretched state, which merges into less yielding or successively non-compliant fabric regions at the edge and under which a quasi-non-compliant "catchment fabric" is arranged is used for example as a seat element - a very advantageous Einsitz , that is, a user is resiliently intercepted by the elastic layer and sits at full load of the fabric supported by the inelastic fabric layer, which forms a "catching bag” at a short distance below the stretched elastic fabric layer ,
• Such a progressive insertion behavior is normally only to be achieved by cushioning materials, in particular foams.
• foams when such foams must be transported or kept in stock, high volumes must be used, since in particular foamed oil products, but also other upholstery materials normally only in relaxed, i. voluminous state can be transported and stored.
• connection of the different fabric layers to each other can be more or less strong, i. for example, only every fifth or tenth warp thread may be incorporated into a weft of the underlying or overlying fabric plies, resulting in a relatively low hanger condition.
• a relatively rigid hitch condition is achieved by incorporating the warp yarns of one fabric ply into every other weft of the other fabric ply resulting in a very strong hanger. This can be done by pulling up only every other warp of a fabric layer into the other fabric layer, or by pulling up or pulling down the warp threads of both fabric layers into the other fabric layer, resulting in an extremely strong bond.
• a fabric layer exclusively of elastic threads and an overlying fabric layer is formed exclusively of inelastic threads, wherein the two fabric layers merge edge side into interconnected, formed from elastic and inelastic threads formed fabric layers ,
• a fabric, which is produced by this method thus consists in a preferably central region of a completely inelastic fabric layer, which in the case of using the fabric as a seat or The tension in the elastic fabric layer will cause the inelastic fabric layer located below or above it to become sagging Bends slightly from the elastic fabric layer and, for example, hangs under the elastic fabric layer like a "collection sack".
• the claims 3, 4 and 5 provide in a particularly advantageous manner that graded tissue layers are provided with different connection, embrace the two separate fabric layers.
• Claims 6 - 9 relate to different combinations of elastic or inelastic chains and elastic or inelastic shots. This makes it possible to construct tissue layers and tissue areas in a very targeted manner, which can be adjusted by the designer of the fabric with regard to their elasticity with a wide range of variation. Fabrics produced in this way can be used in a wide variety of fields, for which reference is made to the following method claims.
• the claims 10 - 12 relate to the structure of a fabric with at least three layers of fabric and the different connections of the fabric layers formed.
• Claims 14-22 relate to fabrics which can be produced by the process according to claims 1-13, claims 20-31 relate to particularly advantageous uses.
• the uses include, in particular, areas of application that relate to seating and lying areas.
• areas of application that relate to seating and lying areas.
• In the field of use of sitting and lying arise with such multi-layered and structured in a special way fabrics completely new possibilities.
• car seats or particularly light aircraft seats can be produced with a very good sitting comfort, whereby cushioning materials and springs arranged in the edge region of seating surfaces can be saved.
• the fabric When using the fabric as seating surfaces, for example, elastic body zone areas can weave into the seats, so that a very pleasant progressive seating behavior is achieved.
• the tissues also offer in a particularly advantageous manner.
• sick beds can be made very flat and stored when not in use, so that, for example, in case of disaster, a variety of "padded" hospital beds (but without upholstery) can be transported from a storage location to a disaster site, and this with very low volume and Weight.
• a so-called vacuum bag in which granular material is filled.
• the contours of a body will be forced into the elastic region of the tissue.
• the granular bulk material conforms to the contour shape of the body and is fixed, so that between the two tissue layers as it were a solid storage shell for transporting a spinal injury occurs, which is covered by the elastically yielding fabric layer.
• the multilayer fabrics produced by the method can also be used as medical support corsets, as wall covering elements, as the outer skin of airbags, as transport sleeves and the like, whenever a further layer is to be present under a tensioned elastic surface or layer, which is to define a maximum indentation depth or bulge of the elastic layer.
• the fabric In many areas, particularly in the field of sickness and injury storage, it may be advantageous to coat the fabric with a silver iodide-containing layer, i. This can be used wherever the tissue either comes into direct contact with the skin of a sick or injured person or is touched by many people.
