I Multi-layer composite bat · ^Λ or cut-outs from it

The innovation concerns a relatively thin combined composite

gj stoffbahr or blanks from it, with a special, ine

I special supple, abrasion-resistant textile top layer.

j | The new composite is made up of several layers.

I The top layer consists of a thin and / or light

ί th textile goods made from man-made fibers; it is associated with a

i plastic layer, which has a strength-giving coating »

t has an insert or base made of a textile fiber structure.

I The upper layer material is light, for the imaginary

Purpose of use Insufficiently strong textile goods or textile

I can be used, such as light, open fabrics,

1 which essentially has the textile character -or composite web

I determine from the top.

ί ■

I The top layer is preferably made of a thin and or

I or light knitted fabrics, which are expediently on the surface

{. ■ is roughened or velor or a loop velor

ti surface, made of man-made fibers. To the chemistry—

\ fibers of textile or knitted goods include the known fibers

[made of plastics, mostly thermoplastic, such as polyamides «

ν polyester, polyacrylonitrile, rayon (regenerated cellulose),

\ Spun rayon or similar fiber-forming substances from known

r of chemical nature and provenance, also made of plastics

\ based on known copolymers, including fiber blends of the man-made fibers mentioned, optionally in a mixture with a non-predominant proportion of natural fibers.

The strength of the textile or textile-like top layer is a relatively very thin one; it can be as little as a few millimeters down to a fraction of a millimeter; the weight According to the top layer, in order to take full advantage of the composite material in terms of economy and appearance and to ensure the technical effect, less than 150 g of fiber substance per square meter of surface, preferably have a weight of less than 120 g / m2.

The top layer, which in itself is generally insufficiently strong, is for the appearance and a number of other properties of the new composite decisive, so z. B. in terms of color, feel, character, abrasion, etc. The top layer can add to this in addition to the color, textile and fiber-related character that is already present during manufacture patterned, embossed and <? or or be printed. A special The effect can be caused by the color contrast to the plastic layer underneath.

The plastic layer provided with an on _/ in or underlay can have very different structures or properties; she can z. B. be compact, so consistently consistently of the possible polymeric substances, and this compact layer can be provided with an embossing and / or perforated if desired. Processing with a so-called spiked roller can combine embossing and perforation. However, the plastic layer can also be foamed completely, partially or in layers, the foam structure being open if desired so that air permeability can be guaranteed. The foam layer or layers or the foamed plastic layer can optionally also be perforated.

As plastic for this, preferably also a thin plastic layer those for coating purposes come in the relevant Industry used polymers, polymers and copolymers for use, which the suppleness and ensure good flexibility of the multilayer composite, e.g. B. plasticized vinyl halide polymers, preferably soft PVC and others for coating purposes suitable plastics and, if necessary, synthetic rubbers.

The strength of the plastic layer is improved by placing a textile structure on, in or underlay, preferably Fabric; A so-called mesh fabric, e.g. B. made of natural or man-made fibers as a single or Document. As a result of the use of relatively strong threads in the form of a mesh fabric, i. H. with sufficiently large gaps between the threads through which the coating compound passes homogeneously during coating, on the one hand, high input and tear strengths of the composite achieved and on the other hand when using weldable plastics As a coating material, good weldability and strong weld seams are achieved. For the production of the opening, or underlay come both natural and synthetic or semi-synthetic fibers (so-called chemical fibers) or Fiber mixtures in question, for example cotton, rayon, glass, plastics such as polyamides, polyester, polyacrylonitrile or the like fiber-forming substances, including natural substances.

The top layer and the plastic layer can be connected to one another in various ways, advantageously by a lamination process using lamination paste or adhesive,

if necessary with the participation of an adhesion improver on the basis of, for example, isocyanate compounds. Such lamination processes are known. However, the top layer can also be placed in the same when the plastic layer is produced insert, especially if, for example, the last spread is still in a pasty state. Alternatively can the back of the top layer can also be thinly pre-coated with an adhesive paste or the like. Both of them can Layers are connected to one another in the so-called hot doubling process.

After the composite material has been produced, it is expedient to do so on the fly Process as a web, it can be embossed, perforated, perforated embossed and / or printed. The Oberschijht can also be printed in one or more colors beforehand. To improve the appearance and for desired special uses so many variations are possible.

Various roughened or velor-like fabrics or textiles are already known they are z. B. used as upholstery fabrics, if they have the strength required for the intended purpose. It is still known these textiles to reinforce by gluing a fabric or other stronger material.

The new multilayer composite is textile-like, in particular in appearance; its grip is pleasant from the top; because of the wide scope for designing, Embossing and printing can be produced in many variants for different purposes.

The composite according to the innovation is ideally suited as Upholstery and covering fabric; he has a pleasant seating comfort

on, especially in a breathable design; it can be, for example, considerably lighter and therefore cheaper Knitted velor qualities for very hard-wearing upholstery fabrics process; these very light knitted velor qualities namely throw through the plastic layer with textile inlay, pad or underlay reinforced, supported and stabilized in shape. This effect is increased if the plastic layer is set thicker or tighter, so that the product is more like artificial leather.

The multi-layer composite is light and easy to clean * especially with a waterproof underlayer! it is hard-wearing and wear-resistant, namely from the synthetic fiber of the The top layer and also because the fibers are anchored in numerous places in the plastic layer. The new composite has an astonishingly smooth surface when used for covering purposes and "quick" pail.

Another advantage of the new product has its special embossing by the embossing pattern without melting together of synthetic fibers of the topsheet, to a certain extent by embossing the bottom layer through the topsheet, wherein observation of the temperature difference of the softening generated; This means, in contrast to embossed Verlours or the like, the preservation of the plores and / or the pain structure on the entire surface.

The multilayer composite is still very elegant welded for example by high-frequency, and it comparable. does not stretch when sewing. In contrast to the raw material used for the top layer, the material has a high tear strength and tear strength.

The surface of the Mister 1 is also produced without embossing. The feister 2, on the other hand, is additionally provided with an embossing (the plastic layer). In pattern 3, the composite web is embossed to perforate, so that the web while maintaining the velor quality. the top layer is permeable to air.

The (gray) pattern 4 has a printed polyamide 6,6 velor as the top layer. The reinforcement fabric of the plastic layer is on the underside of this blank of a composite sheet according to the innovation not entirely made of plastic enveloped.
