Description

Die vorliegende Erfindung betrifft silikonisierte Einlagestoffe, insbesondere Vliesstoffe, mit einer dauerhaften Hydrophobierung, deren Herstellung und deren Verwendung als Einlagen für Textilien.The present invention relates to siliconized interlinings, in particular Nonwovens, with a permanent hydrophobization, their production and their use as inlays for textiles.

Die Hydrophobierung von Substraten mit Siloxanen ist eine bereits seit langem erprobte Technik.The hydrophobization of substrates with siloxanes has long been one proven technology.

Die WO-A-01/40,359 beschreibt die Behandlung eines organischen polymeren Materials, wobei ein Substrat enthaltend ein Polymer mit einem Plasma behandelt wird, dem ein siliziumorganisches Additiv zugesetzt worden ist. Auf der Oberfläche des Substrates entsteht dadurch ein Überzug aus SiOx-Gruppen.WO-A-01 / 40,359 describes the treatment of an organic polymeric material, a substrate containing a polymer being treated with a plasma to which an organosilicon additive has been added. This creates a coating of SiO x groups on the surface of the substrate.

Die WO-A-02/28,548 beschreibt ein Verfahren und eine Vorrichtung zum Erzeugen einer Beschichtung. Dabei wird ein feinverteiltes schichtbildendes Material in ein atmosphärisches Plasma eingedüst und schlägt sich auf der zu behandelnden Substratoberfläche nieder. Das Verfahren eignet sich insbesondere zur Herstellung von siliziumorganischen Überzügen. Als geeignete Substrate werden auch textile Flächengebilde, wie Vliesstoffe, erwähnt.WO-A-02 / 28,548 describes a method and an apparatus for Create a coating. This creates a finely divided layer-forming Material injected into an atmospheric plasma and strikes on the treating substrate surface. The procedure is suitable especially for the production of organic silicon coatings. As Suitable substrates are also textile fabrics, such as nonwovens, mentioned.

Der Einsatz von textilen Flächengebilde als Textileinlagen ist bereits seit langem bekannt. Derartige Einlagen sind auch bereits mit Textilien verklebt worden und zu diesem Zweck werden die Einlagen mit Klebeschichten versehen (vergl. Lünenschloss / Albert "Vliesstoffe", S. 299-304, G. Thieme Verlag, Stuttgart, New York (1982)).The use of textile fabrics as textile inlays has been around since known for a long time. Such inserts are already glued to textiles and for this purpose the inserts with adhesive layers provided (see Lünenschloss / Albert "Vliesstoffe", pp. 299-304, G. Thieme Verlag, Stuttgart, New York (1982)).

Bei der Verarbeitung von Einlagen kann es vorkommen, dass das Material der Klebschicht neben der Verbindungen mit dem Textil auch durch das die Einlage bildende Material fließt und dessen Eigenschaften in nachteiliger Weise verändert.When processing deposits, the material of the Adhesive layer in addition to the connections with the textile also through the insert forming material flows and its properties disadvantageously changed.

Man hat auch bereits Einlagestoffe auf nasschemischem Wege silikonisiert, um deren Griff zu verbessern, das Eindringen des Haftmaterials in die Einlage zu verhindern sowie das Verlaufen des Haftmaterials bei dessen Auftrag auf die Oberfläche des Einlagestoffes zu verhindern. Derart hergestellte Einlagen weisen jedoch relativ hohe Anteile an Silikon auf. Typische Dicken der Silikonschichten bewegen sich im Bereich von 80 bis 200 nm.One has also already siliconized interlinings by wet chemical methods in order to to improve their grip, the penetration of the adhesive material into the insert prevent and the running of the adhesive material when it is applied to the To prevent surface of the interlining. Inserts made in this way however, have relatively high proportions of silicone. Typical thicknesses of the Silicone layers range from 80 to 200 nm.

Ausgehend von diesem Stand der Technik werden durch die vorliegende Erfindung textile Flächengebilde bereitgestellt, die eine Kombination von Weichgriff, Glätte, Glanz, Fülle und Elastizität bei gleichzeitiger hervorragender Permanenz aufweisen, die nur geringe Mengen an Silikon aufweisen und die in einfacher und umweltschonender Weise hergestellt werden können. Die erfindungsgemäßen Einlagestoffe zeigen bei deutlich geringeren Anteilen an Silikon im Vergleich zu herkömmlichen, nasschemisch hergestellten Einlagestoffen vergleichbare oder sogar verbesserte Eigenschaften.Based on this prior art, the present Invention textile fabrics are provided which are a combination of Soft feel, smoothness, shine, fullness and elasticity while being excellent Have permanence, which only have small amounts of silicone and which in can be manufactured in a simple and environmentally friendly manner. The Interlining materials according to the invention indicate at significantly lower proportions Silicone compared to conventional, wet-chemically manufactured interlinings comparable or even improved properties.

Besonders bevorzugt kommen Vliesstoffe mit geringen Flächengewichten von 5 bis 150 g/m2 zum Einsatz.Nonwovens with a low basis weight of 5 to 150 g / m 2 are particularly preferably used.

Als fadenbildende Polymere können in Abhängigkeit vom ins Auge gefassten Verwendungszweck unterschiedlichste Polymere zum Einsatz kommen.As thread-forming polymers, depending on the envisaged A wide variety of polymers are used.

Beispiele für Polymere sind Polyester, insbesondere Polyethylenterephthalat, Polybutylenterephthalat oder Copolymere enthaltend Polyethylenterephthalateinheiten oder Polybutylenterephthalateinheiten, Polyamide, insbesondere von aliphatischen Diaminen und Dicarbonsäuren, von alphatischen Aminocarbonsäuren oder von aliphatischen Lactamen abgeleitete Polyamide, oder Aramide, also von aromatischen Diaminen und Dicarbonsäure abgeleitete Polyamide, Polyvinylalkohol, Viskose oder Mischungen von zweien oder mehreren dieser Polymeren.Examples of polymers are polyesters, especially polyethylene terephthalate, Polybutylene terephthalate or copolymers containing polyethylene terephthalate units or polybutylene terephthalate units, polyamides, in particular from aliphatic diamines and dicarboxylic acids, from alphatic aminocarboxylic acids or polyamides derived from aliphatic lactams, or aramids, that is, polyamides derived from aromatic diamines and dicarboxylic acid, Polyvinyl alcohol, viscose or mixtures of two or more of these Polymers.

Erfindungsgemäße Einlagestoffe können in an sich bekannter Weise verfestigt sein, beispielsweise durch mechanisches oder hydraulisches Nadeln, durch Aufschmelzen von im Einlagestoff vorhandenen Bindefasern, durch thermischmechanisches Verfestigen oder durch Applikation von Bindemitteln.Interlinings according to the invention can be solidified in a manner known per se be, for example by mechanical or hydraulic needling, by Melting of binding fibers in the interlining material through thermal mechanical Solidify or by applying binders.

Es wurde gefunden, dass die erfindungsgemäßen Einlagestoffe durch eine Plasmabehandlung hergestellt werden können. Dadurch werden auf den Fasern des Einlagestoffes dünne silizium-haltige Schichten ausgebildet, die einerseits eine Sperrwirkung für das oberflächlich aufgebrachte Haftmittel bewirken und andererseits den Griff des Einlagestoffes infolge verbesserter Faser-Faser-Gleitwirkung deutlich verbessern.It has been found that the interlinings according to the invention are characterized by a Plasma treatment can be made.

Bei der erfindungsgemäßen Silikonisierung der Fasern werden im Vergleich zu herkömmlichen nasschemischen Verfahren nur geringe Mengen an siliziumhaltigem Material abgeschieden. Dieses äußert sich in einer geringen Dicke der auf den Fasern ausgebildeten Schichten. Die Schichtdicken bewegen sich dabei im oben angegebenen Bereich und lassen sich z.B. mittels Röntgenphotoelektronenspektroskopie bestimmen. Dabei lassen sich Schichtdicken von bis zu 10 nm bestimmen, was der theoretischen Informationstiefe dieser oberflächenanalytischen Methode entspricht. Größere Schichtdicken lassen sich mittels AFM, Ellipsometrie oder REM bestimmen.In the siliconization of the fibers according to the invention, compared to conventional wet chemical processes only in small amounts deposited silicon-containing material.

In particular, the silicon-containing layer is additionally cross-linked. This increases the life of this layer. Alkylsilanes or alkoxysilanes, for example, are used to produce such flat structures: for example methylhydrogen silanes, tri- or tetraalkoxysilanes and triaminoalkylsilanes. Instead of this or in a mixture with it, silanes, for example SiH 4 or Si 2 H 6 , can also be used.

In der Regel handelt es sich um thermoplastische Polymere, die bei Temperaturen unterhalb des Schmelz- bzw. Zersetzungspunktes der Fasern, die den Einlagestoff bzw. das damit zu verbindende Textil bilden, schmelzen.
