Definitions

  • the present invention relates to textile fabrics which comprise a structure of fibers, which by means of a polymer Binders are interconnected (nonwovens) and a Process for their production.
  • a structure of fibers is used to produce a nonwoven (Fleece), which is then solidified or glued.
  • the fibers can have a preferred direction or non-directional his.
  • Various processes are known for producing nonwovens, e.g. (1) the mechanical formation of fleece from staple fibers or filaments; (2) aerodynamic web formation from staple fibers or Filaments; (3) hydrodynamic web formation from staple fibers or filaments and (4) electrostatic web formation Fine fibers or filaments.
  • the so obtained Nonwovens become nonwovens using different processes solidified.
  • Nonwovens are used for a large number of applications used. For example, nonwovens are increasingly as cleaning and Wipes, dishcloths and napkins used. In these applications it is important that e.g. spilled liquids, such as milk, coffee, etc., quickly and completely when wiping over soaked up and completely damp surfaces become. The speed and completeness with which Liquids are sucked up, determine the usage properties of a cleaning and wiping cloth and are the main criteria for the goodness of the item.
  • a cleaning cloth absorbs liquids the quicker the faster their transport takes place on the fiber surface.
  • a hydrophilic The surface is easily and quickly wetted by water. The water spreads very quickly over the entire surface of the nonwoven and the water is "sucked away" from the contact point. Hydrophobic In contrast, surfaces are not wetted. You run the Liquid therefore also no further and are for one use unsuitable as cleaning cloth or wipe.
  • Crucial for the crowd of liquid that can be absorbed is, among other things also the swelling behavior of the fiber.
  • a hydrophobic binder that largely envelops the fiber affects the kinetics of the Water absorption.
  • nonwovens To improve the water absorption properties of nonwovens are sometimes surface-active hydrophilizing in their manufacture Agents such as emulsifiers, surfactants or wetting agents are used. This makes for excellent initial hydrophilicity reached.
  • these nonwovens have the disadvantage that the hydrophilic agents through water or other aqueous media be washed out gradually. After repeated contact with water the product becomes increasingly hydrophobic. The flushing, cleaning or Wipe thus loses its ability to wash quickly absorb aqueous liquids. The cloth will consequently unusable for further use, and must be disposed of although the mechanical strength of the cloth for further Use cycles are still sufficient. This is with regard to one responsible handling of raw materials disadvantageous.
  • the present invention was therefore based on the object To provide hydrophilic fabrics, its hydrophilicity is retained even after repeated washing.
  • the present invention therefore relates to a textile fabric, which comprises a structure of fibers, which by means of a polymer Binder are interconnected, and characterized is that the fabric is an oxide and / or hydroxide of Al, B, Si, Mg, Ti and / or Zn in a colloidal dispersion and one selected from sulfosuccinates and sulfosuccinamates Contains wetting agents.
  • the present invention further relates to a method of manufacture of a textile fabric, in which a structure of Impregnated fibers with a dispersion of a polymeric binder, dried, and optionally hardened, the result is characterized in that the structure also (i) with a colloidal Suspension of an oxide and / or hydroxide of Al, B, Si, Mg, Ti and / or Zn is impregnated or with a solution Precursor of an oxide and / or hydroxide of Al, B, Si, Mg, Ti and / or Zn is impregnated and the formation of the oxide and / or Hydroxide is induced in a colloidally disperse distribution and (ii) the structure with one among sulfosuccinates and sulfosuccinamates selected wetting agent is impregnated.
  • the textile fabric according to the invention preferably contains 1 - 20% by weight, based on the dry weight of the polymeric binder, in particular 3 -15% by weight and particularly preferably 5 - 15% by weight, oxide and / or hydroxide of Al, B, Si, Mg, Ti and / or Zn.
  • the textile fabric according to the invention preferably contains 1 - 20% by weight, based on the dry weight of the polymeric binder, in particular 2-10% by weight, wetting agent.

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 textile fabrics which comprise a structure of fibers, which by means of a polymer Binders are interconnected (nonwovens) and a Process for their production.

Zur Herstellung eines Vliesstoffs wird ein Gefüge von Fasern (Vlies) abgelegt, das anschließend verfestigt bzw. verklebt wird. Die Fasern können eine Vorzugsrichtung aufweisen oder ungerichtet sein. Zur Vliesherstellung sind verschiedene Verfahren bekannt, z.B. (1) die mechanische Vliesbildung aus Spinnfasern oder Filamenten; (2) die aerodynamische Vliesbildung aus Spinnfasern oder Filamenten; (3) die hydrodynamische Vliesbildung aus Spinnfasern oder Filamenten und (4) die elektrostatische Vliesbildung aus Feinstfasern oder Filamenten. Die auf diese Weise gewonnenen Vliese werden nach unterschiedlichen Verfahren zu Vliesstoffen verfestigt.A structure of fibers is used to produce a nonwoven (Fleece), which is then solidified or glued. The fibers can have a preferred direction or non-directional his. Various processes are known for producing nonwovens, e.g. (1) the mechanical formation of fleece from staple fibers or filaments; (2) aerodynamic web formation from staple fibers or Filaments; (3) hydrodynamic web formation from staple fibers or filaments and (4) electrostatic web formation Fine fibers or filaments. The so obtained Nonwovens become nonwovens using different processes solidified.

Die größte Bedeutung haben nasse Bindeverfahren. Hierbei wird das Vlies mit einem wässrigen Bindemittel, z.B. einem Polymerlatex behandelt und anschließend, gegebenenfalls nach Entfernung von überschüssigem Bindemittel, getrocknet und gegebenenfalls gehärtet. Es gibt eine große Zahl weiterentwickelter Verfahren, die aber letztlich auf diesem Grundprinzip beruhen.Wet binding methods are of greatest importance. Here is the Fleece with an aqueous binder, e.g. a polymer latex treated and then, if necessary after removal of excess binder, dried and optionally hardened. There are a large number of advanced processes that but ultimately based on this basic principle.

Vliesstoffe werden für eine große Zahl von Einsatzmöglichkeiten verwendet. So werden Vliesstoffe z.B. zunehmend als Putz- und Wischtücher, Spültücher und Servietten verwendet. Bei diesen Anwendungen ist es wichtig, daß z.B. verschüttete Flüssigkeiten, wie Milch, Kaffee, usw., beim Darüberwischen rasch und vollständig aufgesaugt und feuchte Oberflächen vollständig getrocknet werden. Die Geschwindigkeit und die Vollständigkeit, mit der Flüssigkeiten aufgesaugt werden, bestimmen die Gebrauchseigenschaften eines Putz- und Wischtuches und sind die Hauptkriterien für die Güte des Artikels.Nonwovens are used for a large number of applications used. For example, nonwovens are increasingly as cleaning and Wipes, dishcloths and napkins used. In these applications it is important that e.g. spilled liquids, such as milk, coffee, etc., quickly and completely when wiping over soaked up and completely damp surfaces become. The speed and completeness with which Liquids are sucked up, determine the usage properties of a cleaning and wiping cloth and are the main criteria for the goodness of the item.

Ein Putztuch saugt Flüssigkeiten umso rascher auf, je schneller deren Transport auf der Faseroberfläche erfolgt. Eine hydrophile Oberfläche wird leicht und rasch von Wasser benetzt. Das Wasser verteilt sich sehr schnell über die gesamte Fläche des Vliesstoffes und das Wasser wird von der Kontaktstelle "abgesaugt". Hydrophobe Oberflächen werden dagegen nicht benetzt. Sie leiten die Flüssigkeit daher auch nicht weiter und sind für einen Einsatz als Putz- oder Wischtuch ungeeignet. Entscheidend für die Menge an Flüssigkeit, die aufgenommen werden kann, ist unter anderem auch das Quellverhalten der Faser. Ein hydrophobes Bindemittel, das die Faser weitgehend umhüllt, beeinträchtigt die Kinetik der Wasseraufnahme.A cleaning cloth absorbs liquids the quicker the faster their transport takes place on the fiber surface. A hydrophilic The surface is easily and quickly wetted by water. The water spreads very quickly over the entire surface of the nonwoven and the water is "sucked away" from the contact point. Hydrophobic In contrast, surfaces are not wetted. You run the Liquid therefore also no further and are for one use unsuitable as cleaning cloth or wipe. Crucial for the crowd of liquid that can be absorbed is, among other things also the swelling behavior of the fiber. A hydrophobic binder that largely envelops the fiber affects the kinetics of the Water absorption.

Zur Verbesserung der Wasseraufnahmeeigenschaften von Vliesstoffen werden bei deren Herstellung mitunter oberflächenaktive hydrophilierende Agentien, wie Emulgatoren, Tenside oder Netzmittel, eingesetzt. Hierdurch wird eine ausgezeichnete Anfangshydrophilie erreicht. Diese Vliesstoffe weisen aber den Nachteil auf, daß die hydrophilen Agentien durch Wasser oder andere wässrige Medien allmählich ausgewaschen werden. Nach mehrmaligem Wasserkontakt wird das Erzeugnis zunehmend hydrophober. Das Spül-, Putz- oder Wischtuch verliert somit nach mehrmaligem Auswaschen seine Fähigkeit, wässrige Flüssigkeiten rasch aufzusaugen. Das Tuch wird folglich unbrauchbar für die weitere Verwendung, und muß entsorgt werden, obgleich die mechanische Festigkeit des Tuchs für weitere Gebrauchszyklen noch ausreicht. Dies ist im Hinblick auf einen verantwortungsvollen Umgang mit Rohstoffen nachteilig.To improve the water absorption properties of nonwovens are sometimes surface-active hydrophilizing in their manufacture Agents such as emulsifiers, surfactants or wetting agents are used. This makes for excellent initial hydrophilicity reached. However, these nonwovens have the disadvantage that the hydrophilic agents through water or other aqueous media be washed out gradually. After repeated contact with water the product becomes increasingly hydrophobic. The flushing, cleaning or Wipe thus loses its ability to wash quickly absorb aqueous liquids. The cloth will consequently unusable for further use, and must be disposed of although the mechanical strength of the cloth for further Use cycles are still sufficient. This is with regard to one responsible handling of raw materials disadvantageous.

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, ein hydrophiles textiles Flächengebilde bereitzustellen, dessen Hydrophilie auch nach mehrmaligem Auswaschen erhalten bleibt.The present invention was therefore based on the object To provide hydrophilic fabrics, its hydrophilicity is retained even after repeated washing.

Es wurde überraschenderweise gefunden, daß diese Aufgabe durch die Verwendung bestimmter Oxide und/oder Hydroxide in kolloiddisperser Verteilung in Verbindung mit bestimmten Netzmitteln gelöst werden kann.It was surprisingly found that this task was accomplished by the use of certain oxides and / or hydroxides in colloidal disperse Distribution in connection with certain wetting agents solved can be.

These include, in particular, the polyacrylate dispersions, for example based on C 1 -C 4 -alkyl (meth) acrylates, (meth) acrylic acid and / or (meth) acrylamide. Amide-containing polymers or copolymers can be crosslinked with NN-methylol compounds, such as urea-formaldehyde or melamine-formaldehyde resins.

    Es ist von kritischer Bedeutung für die vorliegende Erfindung, daß das Oxid und/oder Hydroxid von Al, B, Si, Mg, Ti und/oder Zn im erfindungsgemäßen Vliesstoff in kolloiddisperser Verteilung vorliegt.

"Colloidal disperse" is meant to mean that the majority of the particles, e.g. more than 90% by weight of the oxide and / or hydroxide one size of <1 µm, in particular <0.1 µm. The colloidal disperse Distribution can be within the scope of the present invention e.g. achieve by going from a colloidal suspension of the oxide and / or hydroxide, e.g. a sol, such as a hydrosol, or one Gel starts or the formation of the oxide and / or hydroxide in colloidal form e.g. as a gel, induced in the fleece.

    Zur Imprägnierung des Vlieses mit der Bindemitteldispersion sind alle gängigen Verfahren der Imprägnierung, z.B. die Imprägnierung mit der Imprägnieranlage oder im Foulard, geeignet. Soweit das Oxid und/oder Hydroxid in Gegenwart des polymeren Bindemittels eine stabile kolloidale Suspension bildet, ist es zweckmäßig, das Oxid und/oder Hydroxid in die Bindemitteldispersion einzuarbeiten. Auf diese Weise können z.B. kolloidale Kieselsäuren verarbeitet werden. Kolloidale Dispersionen bestimmter Oxide und/oder Hydroxide lassen sich nicht in situ in der Bindemitteldispersion herstellen. So neigen z.B. Al3+-Salze dazu, die Dispersion zu koagulieren bzw. es tritt eine Koagulation beim Versuch ein, die Al3+-Salze durch Zugabe einer Base, z.B. von Ammoniak, in Al(OH)3 umzuwandeln. In diesen Fällen ist es zweckmäßig, das Vlies mit einer kolloidalen Suspension, vorzugsweise einer frisch hergestellten kolloidalen Suspension, in der Form eines Sols oder Gels, zu imprägnieren und zu trocknen und anschließend mit dem polymeren Bindemittel zu imprägnieren. Andererseits ist es möglich, das Vlies mit der Lösung eines Vorläufers des Oxids und/oder Hydroxids zu imprägnieren und die Bildung des Oxids und/oder Hydroxids im Vlies zu induzieren. So kann das Vlies z.B. mit einer Lösung von Al3+-Ionen, z.B. einer Al2(SO4)3-Lösung oder einer Al(NO3)3-Lösung, getränkt und vorzugsweise getrocknet werden. Anschließend wird das Vlies mit der Bindemitteldispersion imprägniert. Der neutrale bis leicht alkalische pH-Wert der Dispersion führt zu einer Umwandlung der Al3+-Ionen zu Al(OH)3. Gegebenenfalls kann der Bindemitteldispersion eine pH-regulierende Substanz, beispielsweise ein Puffer, zugesetzt werden, um einen neutralen bis leicht alkalischen pH-Wert, z.B. im Bereich von 6 bis 9, einzustellen.All common methods of impregnation, for example impregnation with the impregnation system or in a padder, are suitable for impregnating the nonwoven with the binder dispersion. If the oxide and / or hydroxide forms a stable colloidal suspension in the presence of the polymeric binder, it is expedient to incorporate the oxide and / or hydroxide into the binder dispersion. In this way, for example, colloidal silicas can be processed. Colloidal dispersions of certain oxides and / or hydroxides cannot be produced in situ in the binder dispersion. For example, Al 3+ salts tend to coagulate the dispersion, or coagulation occurs when an attempt is made to convert the Al 3+ salts into Al (OH) 3 by adding a base, for example ammonia. In these cases, it is expedient to impregnate and dry the fleece with a colloidal suspension, preferably a freshly produced colloidal suspension, in the form of a sol or gel, and then to impregnate it with the polymeric binder. On the other hand, it is possible to impregnate the fleece with the solution of a precursor of the oxide and / or hydroxide and to induce the formation of the oxide and / or hydroxide in the fleece. For example, the fleece can be impregnated with a solution of Al 3+ ions, for example an Al 2 (SO 4 ) 3 solution or an Al (NO 3 ) 3 solution, and preferably dried. The fleece is then impregnated with the binder dispersion. The neutral to slightly alkaline pH value of the dispersion leads to a conversion of the Al 3+ ions to Al (OH) 3 . If necessary, a pH-regulating substance, for example a buffer, can be added to the binder dispersion in order to set a neutral to slightly alkaline pH, for example in the range from 6 to 9.

    Das Vlies oder der Vliesstoff könnte ferner mit einer Wasserglaslösung, d.h. Natriumorthosilikatlösung, getränkt werden, wobei anschließend durch Behandlung mit verdünnter Mineralsäure, z.B. Salzsäure, kolloidale Kieselsäure erzeugt werden kann. Ein weiteres Beispiel ist die Behandlung mit einer wässrigen Lösung von Borax (Na2B4O7 · 10 H2O) mit anschließender Trocknung.The fleece or the nonwoven fabric could also be impregnated with a water glass solution, ie sodium orthosilicate solution, after which colloidal silica can be produced by treatment with dilute mineral acid, for example hydrochloric acid. Another example is treatment with an aqueous solution of borax (Na 2 B 4 O 7 .10 H 2 O) followed by drying.

    Die Imprägnierung des Vlieses oder Vliesstoffes mit der kolloidalen Suspension des Oxids/Hydroxids bzw. die Imprägnierung mit der Lösung des Vorläufers und die Induzierung der Oxid/Hydroxidbildung können zu einem beliebigen Zeitpunkt während der Herstellung des textilen Flächengebildes erfolgen. Es ist bevorzugt, daß sie vor oder gleichzeitig mit der Imprägnierung mit dem Bindemittel erfolgen.The impregnation of the fleece or nonwoven with the colloidal Suspension of the oxide / hydroxide or the impregnation with the Solution of the precursor and induction of oxide / hydroxide formation can be at any time during manufacture of the textile fabric. It is preferred that they before or simultaneously with the impregnation with the binder respectively.

    Die Imprägnierung des Vlieses oder Vliesstoffes mit dem Netzmittel kann zu einem beliebigen Zeitpunkt während der Herstellung des erfindungsgemäßen textilen Flächengebildes erfolgen. Im Allgemeinen ist es zweckmäßig, die Imprägnierung mit dem Netzmittel gleichzeitig mit der Bindemittel-Imprägnierung vorzunehmen. Hierzu wird das Netzmittel einfach zu der wässrigen Bindemitteldispersion gegeben.The impregnation of the fleece or nonwoven fabric with the wetting agent can be at any time during manufacture of the fabric according to the invention take place. In general it is advisable to impregnate with the wetting agent to be carried out simultaneously with the impregnation of the binder. For this purpose, the wetting agent simply becomes the aqueous binder dispersion given.

    Die Erfindung wird nun durch die folgenden Beispiele näher veranschaulicht.The invention is now illustrated in more detail by the following examples.

    Beispiele 1 bis 10Examples 1 to 10

    Polyester-Zellwoll-Vliese (70PES/30ZW; 1,7 dtex; Faserlänge 38 mm; 30 g/m2 einer Länge von 35 bis 50 cm und einer Breite von 25 bis 28 cm wurden in einer Imprägnier- und Absauganlage in Längsrichtung über ein Endlos-PES-Siebband durch eine 25 %-ige Bindemittelflotte und über eine Absaugvorrichtung geführt. Bei der verwendeten Bindemitteldispersion handelte es sich um Acronal DS 2350 X ™ (Polyacrylatdispersion auf der Basis von Butylacrylat und Acrylnitril). Die Bandgeschwindigkeit betrug 1 bis 2 m pro min. Über die verstellbare Stärke der Absaugung wurde der Naßauftrag auf etwa 160% eingestellt, was einem Trockenauftrag von etwa 40% entspricht. Die Bindemittelflotte enthielt die in der nachstehenden Tabelle angegebenen Zusatzstoffe (Gew.-%, bezogen auf das Trockengewicht des Bindemittels). Die imprägnierten Vliese wurden auf das Band eines Mathis-Siebbandtrockners Typ TH aufgelegt, gegen Verrutschen gesichert und 2 min lang bei 150°C getrocknet. Die Oberseite des jeweiligen Vlieses wurde gekennzeichnet, und durch Wiegen wurde die Auftragsmenge bestimmt.Polyester cellulose fleeces (70PES / 30ZW; 1.7 dtex; fiber length 38 mm; 30 g / m 2 a length of 35 to 50 cm and a width of 25 to 28 cm were in a longitudinal impregnation and suction system over a Endless PES sieve belt passed through a 25% binder liquor and through a suction device The binder dispersion used was Acronal DS 2350 X ™ (polyacrylate dispersion based on butyl acrylate and acrylonitrile). The belt speed was 1 to 2 m per The wet application was adjusted to about 160%, which corresponds to a dry application of about 40%, via the adjustable strength of the suction .. The binder liquor contained the additives listed in the table below (% by weight, based on the dry weight of the binder). The impregnated nonwovens were placed on the belt of a Mathis sieve belt dryer type TH, secured against slipping and dried for 2 minutes at 150 ° C. The top of the respective fleece was marked and the quantity applied was determined by weighing.

    Die so erhaltenen Vliesstoffe wurden unmittelbar und nach fünfmaligem Waschen einem Benetzungstest unterzogen. Das Waschen geschah, indem der Vliesstoff in einem 5 l Eimer mit Leitungswasser unter Wasser mit der Hand etwa 15 mal ausgedrückt (ausgewrungen), dann in ein Handtuch eingewickelt und darin trockengewrungen wurde. Dieser Vorgang wurde 5 mal wiederholt.The nonwovens thus obtained were immediately and after five times Wash subjected to a wetting test. The washing happened by placing the nonwoven in a 5 liter bucket of tap water expressed under water by hand about 15 times (wrung out), then wrapped in a towel and wrung dry in it has been. This process was repeated 5 times.

    Zur quantitativen Bestimmung der Hydrophilie wurde der farbige Ablauftest herangezogen. Dieser Test läuft im Wesentlichen folgendermaßen ab: Auf den schräg eingespannten Vliesstoff wird eine definierte Menge eingefärbtes Wasser aufgebracht. Je nach Hydrophilie läuft das Wasser ab oder dringt mehr oder weniger schnell in den Vliesstoff ein. Dadurch werden charakteristische Farbflecken, z.B. kreisrund für schnelles Eindringen in den Vliesstoff bzw. schmal und länglich für langsames Eindringen und bevorzugtes Ablaufen, erhalten. Die Beurteilungen werden nach einer Notenskala zugeordnet.For the quantitative determination of the hydrophilicity, the colored Run test used. This test basically runs as follows ab: A is placed on the diagonally clamped nonwoven defined amount of colored water applied. Depending on the hydrophilicity the water runs off or penetrates more or less quickly into the nonwoven. Characteristic spots of color, e.g. circular for quick penetration into the nonwoven fabric or narrow and elongated for slow penetration and preferred Expire, get. The assessments are based on a grading scale assigned.

    Zur Durchführung der Prüfung wird ein Prüfkörper der Größe von 21 x 5 cm in einen Rahmen eingespannt, der eine Neigung von 30 Grad gegenüber der Horizontalen beschreibt. Die im Trockner oben liegende Seite weist bei dieser Prüfung nach unten. Mittels einer Pipette werden 0,5 ml Testflüssigkeit aus einer Höhe von 10 mm und einem Abstand zum oberen Vliesrand von 30 mm aufgebracht. Die Testflüssigkeit bestand aus 2 g Hostapal CV-Lösung, 2,5 g Lurantin-Lichtecht-Türkisblau-GL auf 1 l vollentsalztes Wasser. Nach Trocknung des Prüfkörpers (hängend) wird die Vliesoberseite begutachtet und ein Notenwert von 0 für keine Benetzung (Testflüssigkeit vollständig abgelaufen) bis 5 für totale Benetzung zugeteilt.

The side on top of the dryer faces down during this test. Using a pipette, 0.5 ml of test liquid is applied from a height of 10 mm and a distance from the upper fleece edge of 30 mm. The test liquid consisted of 2 g of Hostapal CV solution, 2.5 g of Lurantin-Lightfast-Turquoise Blue-GL to 1 l of completely demineralized water. After the test specimen has dried (hanging), the top of the fleece is examined and a grade of 0 for no wetting (test liquid completely drained off) to 5 for total wetting is assigned. The results are shown in the table below. colored run test Vers. No. mineral.

    Aus der Tabelle ist ersichtlich, daß nur bei den Beispielen 4 und 10 ein Vliesstoff erhalten wurde, der nach 5 maligem Waschen noch hydrophil ist. Diese Beispiele enthielten einen Sulfobernsteinsäureester in Verbindung mit kolloidaler Kieselsäure. Ohne Kieselsäure (Beispiel 2) wird selbst bei Verwendung desselben Emulgators keine permanente Hydrophilie erhalten. Andere Emulgatoren (Beispiel 5, 6) führen nicht zur gewünschten permanenten Hydrophilie. Auch polymere Additive (Beispiel 8) oder höhere Mengen an Kieselsäure in Abwesenheit von Sulfobernsteinsäureestern (Beispiel 9) führen nicht zu den angestrebten Eigenschaften.From the table it can be seen that only in Examples 4 and 10 a nonwoven fabric was obtained after 5 washes is hydrophilic. These examples contained a sulfosuccinic acid ester in connection with colloidal silica. Without silica (Example 2) is even when using the same emulsifier no permanent hydrophilicity obtained. Other emulsifiers (Examples 5, 6) do not lead to the desired permanent hydrophilicity. Also polymeric additives (example 8) or higher amounts of Silica in the absence of sulfosuccinic acid esters (example 9) do not lead to the desired properties.

    Standard-Zellstoff-Vliese (Whatman #4; 100% Zellstoff) einer Länge von 35 bis 50 cm und einer Breite von 25 bis 28 cm wurden im Foulard durch eine 10%ige Bindemittelflotte (Acronal DS 2350 X) gezogen, abgequetscht und anschließend in einem Mathis-Spannrahmentrockner mit Ablagegaze getrocknet. Die Flotte enthielt die in der nachstehenden Tabelle angegebenen Zusatzstoffe. Bei den Beispielen 13 und 14 wurden die Vliese zunächst im Foulard mit einer 5 %igen Al2(SO4)3-Lösung getränkt, abgequetscht und getrocknet und erst dann im Foulard mit Bindemittel getränkt und erneut getrocknet.Standard cellulose nonwovens (Whatman # 4; 100% cellulose), 35 to 50 cm long and 25 to 28 cm wide, were pulled through a 10% binder liquor (Acronal DS 2350 X), squeezed off and then in a Mathis stenter dryer with gauze. The liquor contained the additives listed in the table below. In Examples 13 and 14, the nonwovens were first impregnated in the padding with a 5% Al 2 (SO 4 ) 3 solution, squeezed and dried and only then soaked in the padding with binder and dried again.

    Die erhaltenen Vliesstoffe wurden einem Saugfähigkeitstest unterzogen. Hierzu wurde ein 5 mal gewaschener und getrockneter Vliesstreifen (70 x 30 mm) mit einer Eintauchtiefe von etwa 5 mm in die Testflüssigkeit (s.o.) gehängt und nach 30 s deren Steighöhe notiert. Außerdem wurde die Penetrationsgeschwindigkeit im Vliesstoff gemessen. Hierzu wurden 0,1 ml Testflüssigkeit auf die Vorderseite von 5 mal gewaschenen und getrockneten Vliesstoffproben aufgesetzt und die Zeit notiert, bis der Tropfen ganz in den Vliesstoff eingedrungen ist.

    Aus der Tabelle ist ersichtlich, daß nur die Kombination von mineralischem Füllstoff (Aluminiumoxid/hydroxid bzw. Kieselsäure; Versuche 14, 15) mit Sulfobernsteinsäureester zur gewünschten permanenten Hydrophilie führt. Die Komponenten alleine (Versuche 12, 13) sind hierzu nicht geeignet. Die Beispiele mit nicht kolloidalen mineralischen Zusätzen (Beispiel 16, 17 und 18) zeigen kritisch die Bedeutung der kolloiddispersen Verteilung.From the table it can be seen that only the combination of mineral Filler (aluminum oxide / hydroxide or silica; Experiments 14, 15) with sulfosuccinic acid ester to the desired permanent hydrophilicity. The components alone (attempts 12, 13) are not suitable for this. The non-colloidal examples mineral additives (Examples 16, 17 and 18) show critically the importance of the colloid-disperse distribution.
