Description

Field of application of the invention

The invention relates to a process for the production of decorative textile composite materials which can be used as wall coverings as well as for the production of artificial leather imitations or floor coverings.

Characteristic of the known technical solutions Process for achieving decorative effects on wall coverings by applying textilien fabrics, threads or Filament bundles, films by means of adhesive or adhesive are known. The most commonly used process for producing such composite materials is the laminating process

in which textile threads or fabrics are glued predominantly by means of aqueous polymer dispersions based on Polyvinylacetatbasis on substrates, especially paper webs (DE-OS 2936740, DE-OS 2919163, DD-244371, DD-213464).

Furthermore, bekannnt.daßtextile webs is bonded by means of dry hot melt adhesive on paper webs with transfer paper and printed

be (DE-AS 2643743). DE-GM 7107013 protects the bonding of coarse jute fabrics on wallpaper base paper.

The disadvantage of a large number of known textile wallpaper whose partially only satisfactory strength against

mechanical influences, such as shock and friction effects, after wall application.

With regard to their decorative effect, longitudinal optical orientations of the thread materials or fabric effects dominate. Object of the invention The object of the invention is to improve the visual impression of textile composite materials. Explanation of the essence of the invention

The object of the invention has been found to propose a method which allows the production of textile composite material, which has a high resistance to mechanical influences and on the Betrs chter exerts an optical transverse or longitudinal or transverse / longitudinal effect. According to the invention, the object is achieved in that Nähgewirke or their modifications, which in the weft or warp or weft and warp threads, yarns, threads, tapes, films of native, synthetic, metallic or metal-containing materials, synthetic fibers or combinations of different thread-like materials sewn contain applied by means of an adhesive to substrates, such as paper, nonwovens, films or textile or textile-like fabrics.

Compared with the previously known textile wallpapers with longitudinal or fabric structures, the transverse or transverse / longitudinal orientations of the composite materials according to the invention lead to the optical broadening of the spaces and to an optical highlighting of objects, images, etc.

The use of fancy yarns and twines, such as stitching, jumping, terry yarns, fluorescent threads, wave yarns, etc. allows the production of composite materials with demand-specific or application-specific design options (such as, for example, lighting yarn or material insert in textile wallpapers for marking emergency exits in Public rooms, cinemas, bars, etc. - or high sound-insulating effects when using terry yarns for textile wallpaper, etc.). Further additional decorative effects can be achieved by pigmenting or dyeing the adhesive or carrier material, special pretreatment of individual material webs, such as embossing, printing, brushing, creping, etc., or special post-treatment of the composite materials (embossing, printing, brushing or other known finishing processes).

embodiments

The invention will be explained in more detail below with reference to two examples:

1. On an Ouplextapetenpapierbahn (basis weight i20g / m ² ) 25g / m ² atro a 40% aqueous polyvinyl dispersion are applied by means of a glue applicator and a squeezer with a manufactured according to the known Nähwirktechnologie in the fineness 14 textile surface material (sewing threads: 17texVIS, 60 Weft threads: 84tex 92/8 VIF / Mousbryl "Stichelgarn", 36tex Bw-blended yarn and 36tex Bw-blended yarn in a ratio of 1: 3: 1,110 + 10 threads / dm) pressed by dehydration in a technologically subsequent drying process on drying cylinders and / or drying fields and trimming with or without separating the composite material web is obtained a decorative textile wall wallpaper with Unichara.kter, high strength and typical cross stripe effect of the Nähgewirkes.The color of the wallpaper is determined by the color and tinting strength of the Bw blended yarn The Textiitapete has similar processing characteristics as the well-known heavy paper wallpapers (high-impact wallpapers, vinyl wallpaper, etc.). Other advantages of the wallpaper produced by this method are instead of necessary Neutapezierungen possible Überrollbarkeit the textile surface with aqueous chalk / Polyvinylacetatemulsionen or paints or other color preparations, wherein the textile structure is maintained after drying, and the Trockenabziehbarkeit the textiitapete, in which by splitting the Duplex paper, the textile top is separated from the paper-base adhering to the wall, which serves as an ideal primer for Neutapezierungen.

2. Under analogous technological conditions as in Example 1, but with 35g / m ² atro a 40% aqueous polyvinyl acetate, a Nähgewirke is laminated to the Duplextapetenpapier, which can be characterized by the following parameters:

Fineness chain 9, sewing thread 18; Shot 25tex VIV 96 ± 10 threads / dm; Sewing silk 7,6tex PES matted 72 ± threads / dm and warp thread 140tex Bw yarn 36 ± 2 threads / dm.

This gives a decorative coarse textured textile wallpaper with typical transverse / longitudinal appearance and high resistance to mechanical influences, which shows the same behavior in terms of their processing properties as the textile wallpaper obtained in Example 1.
