"Process for the manufacture of non-woven fabrics"

Es ist bekannt, Textilstoffe dadurch herzustellen, daß man einen Faseraufbau aus willkürlich abgelegten Fasern herstellt und dann die so erhaltene Faserbahn sticht, wodurch eine zusammenhaltende Struktur erhalten wird.It is known to produce textile fabrics by one Manufactures fiber structure from randomly deposited fibers and then punctures the resulting fiber web, creating a cohesive Structure is obtained.

Diese nichtgewebten Textilstoffe weisen jedoch verschiedene Nachr., teile auf, beispielsweise sind sie in ihren Abmessungen nicht stabil j außerdem sind sie nur schwierig mit der erforderlichen Oberflächengleichmäßigkeit herzustellen.However, these nonwoven fabrics have different messages, parts on, for example, they are not stable in their dimensions j in addition, they are difficult with the required Establish surface uniformity.

So vvird gemäß der vorliegenden Erfindung ein Textilstoff vorgeschlagen, welcher dadurch gekennzeichnet ist, daß er aus einer Faserstruktur besteht, welche mindestens 20 $ gekräuselte Fasern und mindestens eine aus einer thermoplastischen Folie bestehenden Schicht, die mehr oder weniger parallel zu und zwischen den Oberflächen der Faserstruktur angeordnet ist, enthält, wobei ein Teil der Fasern in der Faserstruktur in Ebeneen parallel zu den Oberflächen derselben angeordnet sind und andere Fasern der Faserstruktur in Richtung des Querschnitts derselben angeordnet sind und die Schicht aus der thermoplastischen Folie durchqueren., Which is characterized in the present invention, proposed so vvird according to a textile material that comprising at least 20 $ curled fibers and at least one consisting of a thermoplastic film layer, the more or less parallel to and between the surfaces of the fiber structure, it consists of a fibrous structure, is arranged, contains, wherein a part of the fibers in the fiber structure are arranged in planes parallel to the surfaces thereof and other fibers of the fiber structure are arranged in the direction of the cross section thereof and traverse the layer of the thermoplastic film.

Vorzugsweise ist die thermoplastische Folie mit den Fasern verklebt.The thermoplastic film is preferably glued to the fibers.

Die thermoplastische i'Oxie kann auch einen aufgelösten Zustand aufweisen und sich über die gesamte Faserstruktur verteilen. Für verschiedene Zwecke sind jedoch riichtgewebts Textilstoffe, die eine thermoplastische Folie im aufgelösten Zustand enthalten, nicht geeignet, so daß es häufig bevorzugt wird, dpS die thermoplastische Polie ihre Folienform und ihre Lage durch die yerklebebehandlung nicht verloren hat.The thermoplastic i'Oxie can also have a dissolved state and spread over the entire fiber structure. For various purposes, however, directional woven fabrics are one thermoplastic film contained in the dissolved state, not suitable, so it is often preferred that dpS be the thermoplastic Polie its film shape and its position through the adhesive treatment has not lost.

Obwohl der so erhaltene Textilstoff eine zusammenhaltende Struktur ist, in welcher die Faserverschlingung, die durch das Stechen entstanden ist, durch die Entwicklung der Kräuselung verstärkt wurde, wird es bevorzugt, daß die thermoplastische Folie gleichzeitig mit der Kräuselungsbehandlung oder auch nachträglich zu einer Verklebung mit den Fasern veranlaßt wird.Although the fabric obtained in this way has a cohesive structure in which the fiber entanglement created by the stitching has been strengthened by the development of the crimp, it is preferred that the thermoplastic film be bonded at the same time as the curling treatment or also afterwards caused with the fibers.

Die Behandlung, durch welche die thermoplastische Folie klebrig gemacht wird, kann, je nachdem was für ein Produkt gewünscht wird, so durchgeführt werden, daß sie entweder ihre Form als gesonderte Folie beibehält oder sich auflöst und in der Faserstruktur verteilt.The treatment by which the thermoplastic film becomes sticky is made, depending on what is desired for a product, be carried out so that it either retains its shape as a separate film or dissolves and is distributed in the fiber structure.

Die thermoplastische Siie kann aus den verschiedensten Materialien bestehen. Sie sollte jedoch bereits bei einer Temperatur klebrig werden, bei dir die fasern des nichtgewebten Textilstoffs nicht geschädigt werden. Es kommen beispielsweise in Präge: Polyäthylen und Polypropylen sowie andere Stoffe mit einem geeigneten Erweichungspunkt. The thermoplastic Siie can be made from a wide variety of materials exist. However, it should become tacky at a temperature that does not damage the fibers of the nonwoven fabric will. There are for example in embossing: polyethylene and Polypropylene and other materials with a suitable softening point.

Die erfindungsgemäßen Textilstoffe, bei welchen die thermoplastische Folie beim Verkleben ihren Charakter als Folie nicht verloren hat, sind insbesondere als Decken, brauchbar.The textile fabrics according to the invention, in which the thermoplastic Foil has not lost its character as a foil when glued, are particularly useful as blankets.

Die erfindungsgemäßen Textilstoffe, bei denen die thermoplastische Folie sich bei der Verklebung aufgelöst hat, sind etwas dichter und steifer und finden beispielsweise als Preßplatten für Koffer und für Innenauskleidungen für Automobile Verwendung.The textile fabrics according to the invention, in which the thermoplastic Foil has dissolved during gluing, are somewhat denser and stiffer and are used, for example, as press plates for suitcases and for interior linings for automobiles use.

Durch geeignete Auswahl der Stichdichte und der Stichtiefe können verschiedene nichtgewebte Textilstoffe mit einer ansprechenden Oberfläche erhalten werden.By suitable selection of the stitch density and the stitch depth, you can various non-woven fabrics with an attractive surface can be obtained.
