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.
- Fig. 1 is a schematic representation of a Jacquard loom on which the inventive method can be performed.
- Fig. 2 shows a longitudinal section, a two-ply fabric, wherein from top to bottom the two fabric layers a) are unconnected, b) have little attachment, c) have more attachment, d) are connected with fixed attachment, e) with very fixed attachment are connected;
- 3 is a longitudinal section through a three-ply fabric, wherein a) the three layers of fabric are unconnected, b) are connected with little attachment, c) are connected with fixed attachment;
- Fig. 4 is a plan view of a portion of a fabric panel having zones of different hitch and elasticity
- FIG. 5 is a plan view of a fabric web also with outwardly increasing connection
- Fig. 6 is a plan view of a fabric web of a third embodiment, in which elongated stiffening elements can be introduced.
- the there only schematically illustrated jacquard weaving machine 1 has two warp beams 2, 3, from which warp threads 4, 5 enter the weft region 6 of the jacquard weaving machine and there are raised and lowered by the harness 7 to form sheds. In the looms weft yarns are entered, which are not visible in the representation of Figure 1.
- the forming fabric 8 runs out after entry of the weft threads and compression on the left side of the jacquard loom 1 and is rolled up on a cloth beam 9.
- Figure Ia the two warp beams are shown, wherein the warp beam 3 is wound over its entire width exclusively with inelastic warp threads.
- the upper warp beam 2 represented in FIG. 1b, which forms the warp I, is partially wound with inelastic warp threads 4 'and partially with elastic warp threads 4 ".
- FIG. 2 There, a two-ply fabric is shown in different attachments.
- An upper fabric layer 20 and a lower fabric layer 21 are formed.
- the upper fabric layer 20 consists exclusively of elastic warp 4 "and elastic weft threads 10th
- the lower fabric layer 21 consists exclusively of non-elastic warp threads 4 'and 5 and non-elastic weft threads 11.
- B ei the tissue with little attachment according to Figure 2b shows that z. B. after every eighth shot a warp thread 5 is pulled from the lower fabric layer 21 into the upper fabric layer 20 and is integrated there by the elastic weft. It is of course equally possible to pull an elastic warp thread 4 "or an inelastic warp thread 4 'or both down from the upper fabric layer 20 and to tie it into the lower inelastic weft.
- a reinforced attachment is achieved by attaching a lower warp thread 5 after every fourth shot.
- the warp thread 5 is attached to the weft 10 of the upper fabric layer 20 after every second Shot.
- a very firm attachment according to Figure 2e is achieved in that alternately with each shot upper and lower warp threads are involved in each case in the other fabric layer.
- the uppermost fabric layer 30 consists exclusively of elastic warp threads 4 ", the middle and lower fabric layers 31, 32 have exclusively inelastic warp threads 4 ', 5.
- elastic weft threads 10 are inscribed into the lower fabric layer exclusively inelastic weft threads, thereby forming three fabric layers 30, 31, 32 with different elasticities.
- weft threads 10 of the uppermost fabric layer 30 is incorporated, the lower fabric layer 32 is detached from the two fabric layers 30 and 31.
- all three fabric layers 30, 31, 32 are connected in that a warp thread is inserted into each of the respective lower fabric layers in an overlying fabric layer
- FIG. 4 In the embodiment shown in Figure 4 is shown schematically how a fabric 40 can be formed with different zones with different elasticity.
- the fabric 40 which runs out of the weaving machine 1 in the direction of arrow 41, is divided, for example, into two juxtaposed regions 40a and 40b, the regions 40a and 40b being identical in the exemplary embodiment. It's just as good Of course it is possible to weave different structures of completely different elasticity and training on the two sides of the forming fabric web.
- a centrally arranged region 42 is completely double-layered, i. in him, according to the sectional view in Fig. 4a, the fabric layers 20 and 21 (assuming a two-ply fabric) are separated, i. There is no connection of the two fabric layers 20, 21 in region 42.
- region 43 which surrounds region 42, there is a zone with relatively little attachment according to FIG. 2b, in region 44, for example, a zone with more attachment according to FIG. 2c can be woven and in area 45 a fixed attachment zone according to FIG. 2d.
- the edge region 46 can be produced with a very strong attachment, for example according to FIG. 2e.
- the zones of different connectivity and elasticity can of course also be arranged entirely differently within the fabric web. Not only can two adjacently located regions 40a and 40b be formed, just as well can only one tissue region or far more than two tissue regions be arranged in different juxtaposition. Just as well, it is also possible that the zones of different connectivity and elasticity are not lying one inside the other but next to each other, depending on the intended use of the fabric.
- the exemplary embodiment according to FIG. 4 can be provided, for example, for producing a seat surface, wherein the region 42 with separately present fabric webs is approximated to a seat region.
- the elasticity does not decrease in zones to the outside, but decreases continuously from a central region 52 through increasing binding, which is represented by the narrowing white lines in region 53, to an edge region 56 in which there is a very strong connection, for example, according to 2e.
- FIG. 6 shows that a fabric can be produced which has continuously increasing outward binding in the weft direction 61, which is illustrated by the increasingly dense white lines, but in the warp direction 62 adjacent bonding zones can be formed, which are interrupted by pocket regions 63 in which there is no connection at all. If necessary, stiffening strips or the like can be inserted into the pocket regions 63. For example, the central areas 64 again exist without any connection.
- Elastic weft and warp threads may consist of polyester or other fibers such as Lycra or elastane or of other elastic materials.
- Vegetable fibers animal fibers, mineral fibers and man-made fibers as well as mixtures thereof are suitable for the inelastic weft and warp threads.
- vegetable fibers may be cotton, kapok, linen, hemp, ramie, jute, manila, sisal or
- coconut, animal fibers may in particular be wool, mohair, cashmere, alpaca, llama,
- Camel hair, angora and silk, mineral fibers are especially glass wool
- Rockwool and metal fibers are understood as fibers of viscose, rayon, modal, acetate, viscose rayon, polyester, polyacrylic, polyamide, polypropylene,
