Description

Die vorliegende Erfindung betrifft textile Flächengebilde, die ein Gefüge von Fasern umfassen, welche mittels eines polymeren Bindemittels miteinander verbunden sind (Vliesstoffe) und ein Verfahren zu ihrer Herstellung. The present invention relates to fabrics comprising a web of fibers, which are interconnected by means of a polymeric binder (non-wovens), and a method for their preparation.

Zur Herstellung eines Vliesstoffs wird ein Gefüge von Fasern (Vlies) abgelegt, das anschließend verfestigt bzw. verklebt wird. For producing a nonwoven fabric, a web of fibers (non-woven) is stored, which is then solidified or bonded. Die Fasern können eine Vorzugsrichtung aufweisen oder ungerichtet sein. The fibers may have a preferred direction or may be non-directional. Zur Vliesherstellung sind verschiedene Verfahren bekannt, z. To produce the fleece different methods are known for. B. (1) die mechanische Vliesbildung aus Spinnfasern oder Fila menten; B. (1) the mechanical fleece formation of textile fibers or Fila elements; (2) die aerodynamische Vliesbildung aus Spinnfasern oder Filamenten; (2) the aerodynamic fleece formation from staple fibers or filaments; (3) die hydrodynamische Vliesbildung aus Spinnfasern oder Filamenten und (4) die elektrostatische Vliesbildung aus Feinstfasern oder Filamenten. (3) the hydrodynamic web formation from staple fibers or filaments, and (4) the electrostatic nonwoven formation of microfibers or filaments. Die auf diese Weise gewonnenen Vliese werden nach unterschiedlichen Verfahren zu Vliesstoffen verfestigt. The webs thus obtained are solidified by different methods to nonwoven fabrics.

Die größte Bedeutung haben nasse Bindeverfahren. Most important are wet bonding process. Hierbei wird das Vlies mit einem wässrigen Bindemittel, z. Here, the nonwoven fabric with an aqueous binder, z. B. einem Polymerlatex behandelt und anschließend, gegebenenfalls nach Entfernung von überschüssigem Bindemittel, getrocknet und gegebenenfalls gehär tet. B. treating a polymer latex and then, optionally after removal of excess binder tet, dried and optionally gehär. Es gibt eine große Zahl weiterentwickelter Verfahren, die aber letztlich auf diesem Grundprinzip beruhen. There are a large number of more advanced methods but ultimately based on this basic principle.

Vliesstoffe werden für eine große Zahl von Einsatzmöglichkeiten verwendet. Nonwovens are used for a large number of applications. So werden Vliesstoffe z. So nonwovens are for. B. zunehmend als Putz- und Wischtücher, Spültücher und Servietten verwendet. B. increasingly used as a cleaning and wiping cloths, dish cloths and napkins. Bei diesen An wendungen ist es wichtig, daß z. These appli cations, it is important that such. B. verschüttete Flüssigkeiten, wie Milch, Kaffee, usw., beim Darüberwischen rasch und vollstän dig aufgesaugt und feuchte Oberflächen vollständig getrocknet werden. B. spilled liquids such as milk, coffee, etc., absorbed quickly and completeness, dig in and wiping over wet surfaces are completely dry. Die Geschwindigkeit und die Vollständigkeit, mit der Flüssigkeiten aufgesaugt werden, bestimmen die Gebrauchseigen schaften eines Putz- und Wischtuches und sind die Hauptkriterien für die Güte des Artikels. The speed and completeness, are sucked up with the liquids, determine the use of own properties of a plaster and wipe and are the main criteria for the quality of the article.

Ein Putztuch saugt Flüssigkeiten umso rascher auf, je schneller deren Transport auf der Faseroberfläche erfolgt. A cleaning cloth sucks fluids more rapidly on, takes place the faster their transport on the fiber surface. Eine hydrophile Oberfläche wird leicht und rasch von Wasser benetzt. A hydrophilic surface is easily and rapidly wetted by water. Das Wasser verteilt sich sehr schnell über die gesamte Fläche des Vliesstof fes und das Wasser wird von der Kontaktstelle "abgesaugt". The water is distributed very rapidly over the entire surface of the Vliesstof fes and the water is "sucked" from the contact point. Hydro phobe Oberflächen werden dagegen nicht benetzt. Hydro phobe surfaces contrast, not wet. Sie leiten die Flüssigkeit daher auch nicht weiter und sind für einen Einsatz als Putz- oder Wischtuch ungeeignet. They do not direct the liquid therefore continue and are unsuitable for use as a plaster or wipe. Entscheidend für die Menge an Flüssigkeit, die aufgenommen werden kann, ist unter anderem auch das Quellverhalten der Faser. Decisive for the amount of liquid that can be added is among others the swelling behavior of the fiber. Ein hydrophobes Bindemittel, das die Faser weitgehend umhüllt, beeinträchtigt die Kinetik der Wasseraufnahme. A hydrophobic binder which substantially encloses the fiber, affects the kinetics of water uptake.

Zur Verbesserung der Wasseraufnahmeeigenschaften von Vliesstoffen werden bei deren Herstellung mitunter oberflächenaktive hydrophi lierende Agentien, wie Emulgatoren, Tenside oder Netzmittel, ein gesetzt. To improve the water absorption properties of nonwoven fabrics during their production sometimes surfactant hydrophi-regulating agents, such as emulsifiers, surfactants or wetting agent, a set. Hierdurch wird eine ausgezeichnete Anfangshydrophilie erreicht. These give excellent initial is achieved. Diese Vliesstoffe weisen aber den Nachteil auf, daß die hydrophilen Agentien durch Wasser oder andere wässrige Medien allmählich ausgewaschen werden. These nonwoven fabrics have the disadvantage that the hydrophilic agents are gradually washed out by water or other aqueous media. Nach mehrmaligem Wasserkontakt wird das Erzeugnis zunehmend hydrophober. After repeated contact with water, the product becomes increasingly hydrophobic. Das Spül-, Putz- oder Wischtuch verliert somit nach mehrmaligem Auswaschen seine Fähig keit, wässrige Flüssigkeiten rasch aufzusaugen. The flushing, cleaning or wiping cloth thus loses his capability after repeated washing ness to absorb aqueous fluids rapidly. Das Tuch wird folglich unbrauchbar für die weitere Verwendung, und muß entsorgt werden, obgleich die mechanische Festigkeit des Tuchs für weitere Gebrauchszyklen noch ausreicht. The cloth is thus unsuitable for further use and must be disposed, although the mechanical strength of the sheet for further usage cycles still sufficient. Dies ist im Hinblick auf einen verantwortungsvollen Umgang mit Rohstoffen nachteilig. This is disadvantageous in terms of a responsible use of raw materials.

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, ein hydrophiles textiles Flächengebilde bereitzustellen, dessen Hy drophilie auch nach mehrmaligem Auswaschen erhalten bleibt. The present invention therefore has for its object to provide a hydrophilic textile fabric whose Hy remains drophilie obtained even after repeated washing.

Hierzu wurden 0,1 ml Testflüssigkeit auf die Vor derseite von 5 mal gewaschenen und getrockneten Vliesstoffproben aufgesetzt und die Zeit notiert, bis der Tropfen ganz in den Vliesstoff eingedrungen ist. For this purpose, 0.1 ml of test liquid were placed on the front of the side of 5 times washed and dried nonwoven fabric sample and the time noted until the drop has penetrated completely into the nonwoven fabric. Die Ergebnisse sind in der nachste henden Tabelle angegeben. The results are shown in the next table Henden.

Tabelle table

Aus der Tabelle ist ersichtlich, daß nur die Kombination von mi neralischem Füllstoff (Aluminiumoxid/hydroxid bzw. Kieselsäure; Versuche 14, 15) mit Sulfobernsteinsäureester zur gewünschten permanenten Hydrophilie führt. From the table it is apparent that only the combination of mi neralischem filler (aluminum oxide / hydroxide, or silicic acid; experiments 14, 15) leads to the desired esters of sulfosuccinic acid with permanent hydrophilicity. Die Komponenten alleine (Versuche 12, 13) sind hierzu nicht geeignet. The components alone (experiments 12, 13) are not suitable for this. Die Beispiele mit nicht kol loidalen mineralischen Zusätzen (Beispiel 16, 17 und 18) zeigen kritisch die Bedeutung der kolloiddispersen Verteilung. The examples with not kol loidalen mineral additives (Example 16, 17 and 18) show the importance of the critical colloidal distribution.
