air-permeable composite material web for upholstery, decorative purposes and the like.

The furnace relates to a composite material web, which is determined in em is permeable to air or gas. The composite material is particularly suitable for use as poster material and for all kinds of decorative purposes.

Artificial leather is already known which does not have a closed surface covering made of plastic, but which The application of plastics through the use of chemical auxiliaries such as swelling agents, gas-releasing agents, through admixture of substances to the coating mass, which are themselves swellable are, such as starch, by adding cork and the like. Or by using appropriate special coating devices is kept air-permeable or interrupted.

Furthermore, artificial leather-like products are known in which the Plastic application, for example, with the help of appropriate patterned ones Rolls is applied in a grid-like manner to the base fabric. This material has the disadvantage that the plastic coating if the product is severely kinked, especially if it is persistent Bends in use, for example as upholstery for automobile seats, breaks and breaks relatively easily can also peel off.

The novelty Yerbund material does not show these disadvantages. The air-permeable Terbund material web is characterized by that it consists of a textile backing layer, which is covered with a fabric, knitted fabric, knitted fabric, Fleece or the like, the thread density of which is chosen so that the finished composite material still has an air permeability, which is measured according to DII 53334, of at least 1 liter per

Minute 100 cm area of this composite material with an overpressure

the air of 20 mm water column, is combined. The Union happens through the application of pressure and / or heat.

The textile substrate is preferably made of a ^fabric: knitted fabrics, Ylies or the like, prepared Zeil- or cotton, that is made of a textile fabric, which is usually also provided for coating in the preparation of known synthetic leathers..

It is particularly advantageous if the fabric, knitted fabric, knitted fabric, fleece or the like. Which with the plastic is encased, consists wholly or partly of synthetic fibers. The so-called Man-made fiber fabrics, i.e. fabrics made from synthetic fibers that are crosslinked from polyamides, polyesters, polyacrylonitrile! and uncrosslinked polyvinyl chloride and / or polyvinylidene chloride, also made of polyurethanes, polycarbonates and The like. Known plastics exist.

From the group of plastics, which are suitable for wrapping the fabrics mentioned, are primarily the To name thermoplastics, roll out of the large group of plastics. These include polyvinyl chloride, especially plasticized polyvinyl chloride and its copolymers, which contain e.g. vinyl acetate and / or vinylidene chloride and the polyacrylates, Polymethyl acrylates or their copolymers with vinyl chloride, Vinyl acetate, butadiene, styrene, etc.

However, other non-thermoplastic ones can also be used Plastics such as crosslinked polyurethanes, crosslinked polyvinyl chloride, vulcanizates of chlorobutadiene and des chlorosulfonated polyethylene or polypropylene
