- the present application relates to a method for the hydrophilic finishing of Fibers that contain exclusively or predominantly polyolefins or polyester of nonwovens containing polyolefin or polyester fibers and fibers or Nonwovens that are made hydrophilic by this process.
- the hydrophilic finish of the fiber remains as long as possible without the water permeability of the nonwoven fabric is reduced. If such nonwovens are processed, for example, in diapers, can be used several times without leaking. In this way the wearing time of the diapers is increased and that caused by used diapers Waste decreased.
- No. 5,045,387 describes, for example, an agent for the hydrophilic finishing of polyolefin fibers, which contains a mixture of an alkoxylated ricinoleic acid derivative, a hydrogenated ricinoleic acid derivative, a C 18 fatty acid and a polyalkoxylated polymethylsiloxane.
- EP 372 890 B1 discloses fibers which comprise polyolefins or polyesters and have been treated with an agent which comprises a fatty acid diethanolamide, a polyether-modified silicone, a sorbitan fatty acid ester and a metal salt of an alkyl sulfonate. The disadvantage of such preparations can be seen above all in their high price.
- the object of the present invention was to provide an improved method to provide with the polyolefin or polyester containing fibers or nonwovens, which contain polyolefin or polyester fibers, can be made hydrophilic, the hydrophilic finish should be retained even after repeated wetting.
- the invention therefore relates to a process for the hydrophilic finishing of fibers which contain exclusively or predominantly polyolefins or polyesters or of nonwovens which predominantly contain such fibers, the nonwovens being mixed with an aqueous dispersion of a preparation which comprises 50 to 95% by weight, based on the total weight of the preparation, at least one quaternary esteramine salt of the formula (I), where R 1 is an aliphatic alkyl radical having 12 to 22 carbon atoms, R 2 is either a radical (CH 2 ) n -O-COR 1 , or an alkyl radical having 12 to 22 carbon atoms, R 3 and R 4 are independently a radical (CH 2 ) n -R 5 , where R 5 is H or OH and n is a number between 1 and 3 and X is either a halide, methosulfate, methophosphate or phosphate ion, 5 to 50 wt .-% of at least one alkyl glycoside with the general

- Nonwovens which are produced either by the so-called “dry laid” method or by the spunbonded method or spunbond method are preferred.
- the "dry laid” process is based on staple fibers, which are usually separated into individual fibers by carding and then folded together using an aerodynamic or hydrodynamic process to form the unconsolidated nonwoven. This is then combined, for example, by a thermal treatment to form the finished fleece (the so-called "thermobonding").
- the synthetic fibers are either heated to such an extent that their surface melts and the individual fibers are joined together at the contact points, or the fibers are coated with an additive which melts during the heat treatment and thus connects the individual fibers together.
- the connection is fixed by cooling.
- all other processes which are used in the prior art for connecting nonwovens are of course also suitable.
- Spunbond formation starts from individual filaments which are formed by the melt spinning process from extruded polymers which are pressed through spinnerets under high pressure.
- the filaments emerging from the spinnerets are bundled, stretched and laid down to form a fleece, which is usually consolidated by "thermobonding".
- the process according to the invention is particularly suitable for nonwovens which are produced by the spunbonded nonwoven or the "dry laid" process.
- the fibers or nonwovens are in the process according to the invention with the preparation made up of quaternary esteramine salt, alkglycoside and optionally glycerin, by preparation in the form of an aqueous dispersion, preferably between 5 and 30% by weight of the preparation, based on the total weight of the dispersion, contains, to which fibers or the nonwoven are applied. All in the Methods and machines customary in textile technology, for example a foulard, are used become.

- a particularly preferred monoester is glycerol monolaurate.
- fibers with a hydrophilic finish which exclusively or predominantly contain polyolefins or polyester or Nonwovens, which predominantly contain fibers claimed after the Process according to the invention are produced.
- These fibers or nonwovens show hydrophilic properties, which are preferably retained even after repeated wetting stay.
- the nonwovens produced according to the invention have a "liquid strike” through “times of less than 10 seconds, especially less than 5 seconds on. Under “liquid strike-through” times, the Understand times that a certain amount of water or artificial urine takes to to get through the fleece to an absorbent underlayer. This time is after the EDANA (European Association of Nonwovens Manufacturers) test method 150.0-84 certainly.
- the "liquid strike through "time should be as short as possible to ensure rapid liquid transport through the fleece to ensure the absorbent material. That way stays the fleece surface is dry, making it more comfortable to wear.

Description
Dieser wird dann beispielsweise durch eine thermische Behandlung zum fertigen Vlies verbunden (das sogenannte "thermobonding"). Dabei werden die synthetischen Fasern entweder soweit erwärmt, daß deren Oberfläche schmilzt und die Einzelfasern an den Kontakstellen miteinander verbunden werden, oder die Fasern werden mit einem Additiv überzogen, welches bei der Wärmebehandlung schmilzt und so die einzelnen Fasern miteinander verbindet. Durch Abkühlung wird die Verbindung fixiert. Neben diesem Verfahren sind natürlich auch alle anderen Verfahren geeignet, die im Stand der Technik zum Verbinden von Vliesstoffen eingesetzt werden.
Die Spinnvliesbildung geht dagegen von einzelnen Filamenten aus, die nach dem Schmelzspinnverfahren aus extrudierten Polymeren gebildet werden, welche unter hohem Druck durch Spinndüsen gedrückt werden. Die aus den Spinndüsen austretenden Filamente werden gebündelt, gestreckt und zu einem Vlies abgelegt, welches üblicherweise durch "thermobonding" verfestigt wird.
Das erfindungsgemäße Verfahren eignet sich insbesondere für Vliesstoffe, die nach dem Spinnvlies-oder dem "dry laid"-Verfahren hergestellt werden.
Als weitere Komponente enthält die im erfindungsgemäßen Verfahren verwendete Präparation in Mengen zwischen 5 und 50 Gew.-%, bezogen auf das Gesamtgewicht der Präparation, Alkylglykoside der allgemeinen Formel RO(G)x, in der R einen primären geradkettigen oder methylverzweigten, insbesondere in 2-Stellung methylverzweigten aliphatischen Rest mit 8 bis 22, vorzugsweise 12 bis 18 C-Atomen bedeutet und G das Symbol ist, das für eine Glykosideinheit mit 5 oder 6 C-Atomen, vorzugsweise für Glucose, steht. Der Oligomerisierungsgrad x, der die Verteilung von Monoglykosiden und Oligoglykosiden angibt, ist eine beliebige Zahl zwischen 1 und 10; vorzugsweise liegt x bei 1,2 bis 1,4. Besonders bevorzugt sind Präparationen, die Alkylglykoside in Mengen zwischen 5 und 30 Gew.-% enthalten.
Die Messungen wurden mit einem Testgerät mit Zeitaufnehmer (Lister-Tester) der Fa. Lenzing AG durchgeführt. Die Testvliese (Polypropylen-spunbond-Vlies mit einem Gewicht von 20g/m2 - Lutrasil® 4420, Fa. Freudenberg) wurden mit der wäßrigen Dispersion der Präparation besprüht. Anschließend wurden die Testvliese bei 70 °C eine Stunde lang getrocknet.
Für die eigentliche Messungen wurden 6 Lagen eines Filterpapiers (Evans-Adlard FF3 WIS 150) unter eine Lage des präparierten Testvliesses gelegt und anschließend mit 5 ml künstlichen Urins (1000 ml dest. H2O, 9 g NaCl) aus dem Lister-Tester in Kontakt gebracht. Die Messungen wurden bei 20 °C und 65 % relativer Luftfeuchtigkeit durchgeführt. Die Zeit, die die Flüssigkeit braucht, um das Vlies zu durchdringen, wurde am Zeitaufnehmer in Sekunden abgelesen.
Um die hydrophilen Eigenschaften der Vliesstoffe bei mehrmaliger Beanspruchung zu messen, wurde das Testvlies nach der ersten Messung, ohne getrocknet zu werden, mit einer neuen Schicht aus Filterpapier unterlegt und die Messung wiederholt.
Zeiten von maximal 5 Sekunden bei jeweils 5 Wiederholungen wurden als gut bewertet. Zeiten über 10 Sekunden wurden nicht mehr wiedergegeben.
