Abstract

The aim of the invention is to produce a textile surface (1), one side of which exhibits hydrophilic properties and the other side hydrophobic properties, whose overall cross-section is hydrophilic. To achieve this, a paste (11) consisting of a viscous emulsion or dispersion of paraffin, polysiloxane and/or fluorine compounds is applied to one side. The layer that has been formed by the first paste (11) is then stabilized by means of a drying process (4) and a second paste (12), consisting of a hydrophilic polymer is subsequently applied to the other side of the textile surface (1), said paste being stabilized by an additional drying process (5). Said steps provide a textile surface (1), which can be produced simply and cost-effectively, is extremely comfortable to wear and which ensures that moisture is immediately absorbed on the hydrophilic side, dispersed over a large area and rapidly removed, whereas the hydrophobic side of said textile surface (1) repels water.

Description

Die Erfindung bezieht sich auf Verfahren zur Herstellung einer textilen Fläche, die auf der einen Seite hydrophobe und auf der anderen Seite hydrophile Eigenschaften aufweist, Vorrichtungen zur Anwendung dieser Verfahren sowie Auftragsmittel, mittels denen die textile Fläche gemäß den Verfahren und Vorrichtungen zu behandeln ist.The invention relates to methods for producing a textile surface, the on the one hand hydrophobic and on the other hand hydrophilic properties devices for the application of these methods and by means of which the textile surface according to the methods and devices to treat is.

Textile Flächen, die die vorgenannten Eigenschaften aufweisen, sind bereits bekannt. Um eine Trennung des hydrophoben Bereichs einer textilen Fläche von deren hydrophilen Bereich zu bewerkstelligen, ist hierbei zwischen zwei Geweben eine unterschiedlich gestaltete Membran angeordnet, die mit den Geweben fest verbunden ist. Die Herstellung derartiger textiler Flächen ist, da dazu mehrere Fertigungsprozesse erforderlich sind, sehr zeitaufwendig und kostenintensiv, außerdem weist die textile Fläche durch die meist an beide Gewebe angeklebte. Membran eine hohe Steifigkeit auf, so daß auch deren Verarbeitung oftmals mit Schwierigkeiten verbunden und deren Einsatz begrenzt ist. Des weiteren ist von Nachteil, daß, bedingt durch die Membran als Zwischenlage, bei einem Bekleidungsstück der Transport von Feuchtigkeit von innen nach außen beeinträchtigt ist und das Kleidungsstück aufgrund der Materialstärke mitunter aufträgt.Textile surfaces that have the aforementioned properties are already known. In order to separate the hydrophobic region of a textile surface from their hydrophilic area to accomplish, here is between two tissues arranged a differently shaped membrane, which stuck with the tissues connected is. The production of such textile surfaces is because several Manufacturing processes are required, very time consuming and costly, In addition, the textile surface by the most adhered to both tissues. Membrane high rigidity, so that their processing often with Difficulties connected and their use is limited. Furthermore, it is from Disadvantage that, due to the membrane as an intermediate layer, at a Garment the transport of moisture from the inside out is impaired and the garment sometimes due to the material thickness applying.

Die JP-A-58-191275 aus dem Jahr 1983 beschreibt Verfahren zum Herstellen von Textilien, die auf Innen- und Aussenseite mit unterschiedlichen Funktionalitäten ausgerüstet sind. Konlaret offenbart sind Gestricke, die an der Innenseite mit einer hydrophilen Ausrüstungsschicht aus vernetzten Acrylatmonomeren versehen sind, während die Aussenseite mit einer hydrophoben Ausrüstungsschicht versehen ist.JP-A-58-191275 of 1983 describes processes for producing textiles, which are equipped on the inside and outside with different functionalities. Konlaret disclosed are knits that are on the inside with a hydrophilic Finishing layer of crosslinked acrylate monomers are provided while the Outside is provided with a hydrophobic finishing layer.

In der JP-A-7-189130 aus dem Jahre 1995 ist wiederum ein Ausrüstverfahren für Gestricke beschrieben. Die fertigen Produkte sollen auch bei starkem Schwitzen des Trägers verhindern, dass ein unangenehmes feuchtes Gefühl auf der Haut entsteht. Um dieses Ziel zu erreichen werden Gestricke eingesetzt, die einen Naturfaseranteil von mindestens 50 % aufweisen um eine sehr gute Wasseraufnahme zu gewährleisten. An einer Aussenseite wird mit einem Kiss Coater eine fluor- oder silikonhaltige Ausrüstungsschicht aufgetragen, die nachfolgend wärmebehandelt werden.
Um beim Tragen kein klebriges Gefühl aufkommen zu lassen wird die Innenseite mit hydrophilen Polymeren beschichtet, die in einem nachfolgenden Heizschritt vernetzt werden.In the JP-A-7-189130 from the year 1995 again a finishing process for knitted fabrics is described. The finished products should prevent even in heavy perspiration of the wearer that creates an unpleasant moist feeling on the skin. To achieve this goal knitted fabrics are used, which have a natural fiber content of at least 50% to ensure a very good water absorption. On the outside, a fluorine- or silicone-containing finishing layer is applied with a kiss coater, which is subsequently heat-treated.
In order to avoid feeling sticky when worn, the inside is coated with hydrophilic polymers, which are crosslinked in a subsequent heating step.

Beide Schriften haben das Bedürfnis nach solchen Bi-funktional ausgerüsteten Textilien auf dem Markt, insbesondere im Bereich der Sport- und Freizeitkleidung erkannt, jedoch haben sich die vorgeschlagenen Techniken und die resultierenden Produkte in den über 20 Jahren seit der Veröffentlichung der JP-A-58-191275 offensichtlich nicht durchsetzen können. Der Markt verlangt weiterhin nach Ausrüstverfahren und entsprechenden Produkten die es erlauben hochwertige Bi-funktionale Textilien mit gleichbleibender Qualität einfach und wirtschaftlich herzustellen.Both writings have the need for such bi-functional finished textiles the market, especially in the field of sports and leisure wear, but have the proposed techniques and the resulting products over the past 20 years since the publication of JP-A-58-191275 obviously can not enforce. Of the Market continues to demand equipment and related products allow high-quality bi-functional textiles with consistent quality easy and produce economically.

Die in den Figuren 1 bis 8 dargestellte und jeweils mit A, B, C oder D bezeichneten Vorrichtungen dienen zum Auftragen einer hydrophob wirkenden Paste 11 oder einer hydrophil wirkenden Paste 12 bzw. einer hydrophob wirkenden Flotte 21 oder einer hydrophil wirkenden Flotte 22 auf eine textile Fläche 1, die über den Gesamtquerschnitt hydrophil ausgebildet ist, und sind unterschiedlich zueinander ausgebildet.Those shown in Figures 1 to 8 and each designated A, B, C or D. Devices are used to apply a hydrophobic paste 11 or a hydrophilic acting paste 12 or a hydrophobic acting fleet 21 or a Hydrophilic acting fleet 22 on a textile surface 1, over the Overall cross section is hydrophilic, and are different from each other educated.

Die Vorrichtungen A nach Figur 1 bzw. A, A' nach Figur 2 bestehen jeweils aus Umlenkrollen 2 und Auflagerollen 3, über die hierbei die hydrophil ausgebildete textile Fläche 1 geführt ist, Beschichtungsrakeln 13 bzw. 14 sowie einem Trockner 4 bzw. zwei Trocknern 4 und 5, die den Beschichtungsrakeln 13 bzw. 14 nachgeschaltet sind. Mittels der Vorrichtung A gemäß Figur 1 wird auf der hydrophil ausgebildeten textilen Fläche 1 auf der einen Seite mittels des Beschichtungsrakels 13 die hydrophob wirkende Paste 11 aufgebracht, die teilweise in die textile Fläche 1 eindringt und in dem Trockner 4 stabilisiert wird. Die mit 1' bezeichnete Seite der textilen Fläche 1 ist somit hydrophob ausgebildet, deren andere Seite 1" bleibt dagegen hydrophil.The devices A according to FIG. 1 or A, A 'according to FIG. 2 each consist of Deflection rollers 2 and 3 Auflagerollen over this case, the hydrophilic textile surface 1 is guided, coating doctor blades 13 and 14 and a dryer. 4 or two dryers 4 and 5, the coating blades 13 and 14 respectively are downstream. By means of the device A according to Figure 1 is on the hydrophilic formed textile surface 1 on the one hand by means of the coating knife 13, the hydrophobic paste 11 applied partially into the textile surface. 1 penetrates and is stabilized in the dryer 4. The designated 1 'side of textile surface 1 is thus formed hydrophobic, the other side 1 "remains on the other hand hydrophilic.

Mit Hilfe der Vorrichtung A', die gemäß Figur 2 der Vorrichtung A nachgeschaltet und in gleicher Weise ausgebildet ist, wird auf der Seite 1" der textilen Fläche 1 dagegen mit Hilfe des Beschichtungsrakels 14 eine hydrophil wirkende Paste 12 aufgetragen, die in dem Trockner 5 stabilisiert wird. Die textile Fläche 1 weist somit eine hydrophob wirkende Seite 1' sowie eine hydrophil wirkende Seite 1" auf.With the aid of the device A ', which according to Figure 2 of the device A downstream and is formed in the same way, on the side 1 "of the textile surface 1 against it applied a hydrophilic paste 12 with the aid of coating knife 14, which is stabilized in the dryer 5. The textile surface 1 thus has a hydrophobic side 1 'and a hydrophilic side 1 "on.

In den Figuren 1 und 2 ist des weiteren dargestellt, daß die hydrophob wirkende Paste 11 bzw. die hydrophil wirkende Paste 12 auf die textile Fläche auch durch Drucken aufgetragen werden kann: Dazu sind strichpunktiert Druckwalzen 31 bzw. 32 vorgesehen, die im Bereich der Auflagerollen 3 angeordnet sind. Die Pasten 11 bzw. 12 werden somit kontinuierlich auf eine oder beiden Seiten 1', 1" der textilen Fläche 1 durch im Rotationsdruckverfahren auf dieser aufgebracht.In Figures 1 and 2 is further shown that the hydrophobic acting Paste 11 or the hydrophilic paste 12 on the textile surface also by Printing can be applied: These are dash-dot pressure rollers 31 and 32, which are arranged in the region of the support rollers 3. The pastes 11 or 12 are thus continuously on one or both sides 1 ', 1 "of the textile Surface 1 applied by the rotary printing process on this.

Nach Figur 3 ist der Vorrichtung A eine Vorrichtung B zugeordnet, die mit einem mit Umlenkrollen 2' und 2" versehenen Tauchbad 23 ausgestattet ist. Dazu ist in einen Trog 24 die Flotte 22 eingefüllt, die hydrophil wirksam und durch die die textile Fläche 1 mit Hilfe der in dem Tauchbad 23 angeordneten Umlenkrolle 2" geführt ist. In dem Trockner 5 wird die Flotte 21 in dem nicht durch die Paste 11 imprägnierten Bereich der textilen Fläche 1 stabilisiert, so daß diese wiederum eine hydrophob wirkende Seite 1' und eine hydrophil wirkende Seite 1" aufweist.According to Figure 3, the device A is associated with a device B, with a with Pulleys 2 'and 2 "provided immersion bath 23. This is in a Trough 24 filled the fleet 22, the hydrophilic effect and through which the textile Surface 1 is guided by means of arranged in the immersion bath 23 guide roller 2 ". In the dryer 5, the liquor 21 is not impregnated in the paste 11 Stabilized area of the textile surface 1, so that these turn a hydrophobic acting side 1 'and a hydrophilic side 1 "has.

Um den Energieäufwand des Trockners 5 gering zu halten, ist dem Tauchbad 23 ein Druckwalzenpaar 25, 26 nachgeschaltet, durch das die textile Fläche 1 hindurchgezogen wird. Mittels des Druckwalzenpaares 25, 26 wird somit der Feuchtigkeitsgehalt der textilen Fläche 1 erheblich reduziert.In order to keep the energy wall of the dryer 5 low, the immersion bath 23 is a Pressure roller pair 25, 26 downstream, through which the textile surface. 1 is pulled through. By means of the pressure roller pair 25, 26 is thus the Moisture content of the textile surface 1 significantly reduced.

Gemäß Figur 4 wird mittels einer Auftragwalze 27 die in einem Trog 28 befindliche Flotte 22 auf der textilen Fläche 1 aufgetragen. Durch zwei Spannrollen 2"' wird die textile Fläche 1 hierbei gegen die Auftragwalze 27, die die Flotte 22 aufnimmt, gepresst, so daß diese auf die textile Fläche 1 übertragen wird. In dem Trockner 5 wird die aufgenommene hydrophil wirkende Flotte 22 in dem von der hydrophob wirkenden Paste 11 nicht beschichteten Bereich stabilisiert, die Seite 1' der textilen Fläche 1 ist demnach hydrophob, deren Seite 1" dagegen hydrophil ausgebildet.According to Figure 4 is located in a trough 28 by means of a applicator roll 27 Fleet 22 applied to the textile surface 1. By two tension rollers 2 "'is the textile surface 1 in this case against the applicator roller 27, which receives the fleet 22, pressed so that it is transferred to the textile surface 1. In the dryer 5 The recorded hydrophilic fleet is 22 in the hydrophobic acting paste 11 uncoated area stabilized, the side 1 'of the textile Surface 1 is therefore hydrophobic, but its side 1 "is hydrophilic.

Die Flotte 22 kann aber auch, wie dies in Figur 5 gezeigt ist, auf die textile Fläche 1 aufgespritzt werden. Dazu dient bei der Vorrichtung D ein Sprühkopf 29, mittels dem die Flotte 22 zur Bildung der hydrophilen Seite 1" der textilen Fläche 1 auf diese aufgetragen wird.The liquor 22 can also, as shown in Figure 5, on the textile surface. 1 be sprayed on. Serves in the device D, a spray head 29, by means of the liquor 22 to form the hydrophilic side 1 "of the textile surface 1 on this is applied.

Nach den Figuren 6, 7 und 8 sind die Vorrichtungen B, C und D jeweils der Vorrichtung A vorgeschaltet. Gemäß Figur 6 wird mit Hilfe des Tauchbades 23 die hydrophil wirkende Flotte 22 in die textile Fläche 1 eingebracht, durch die hydrophob wirkende Paste 11 wird jedoch die Seite 1'der textilen Fläche 1 hydrophob ausgebildet. In gleicher Weise ist die gemäß Figur 7 vorgesehene Kombination der Vorrichtungen C und A wirksam.According to Figures 6, 7 and 8, the devices B, C and D are each of the Device A upstream. According to FIG. 6, with the aid of the immersion bath 23 Hydrophilic acting fleet 22 introduced into the textile surface 1, by the hydrophobic However, acting paste 11, the side 1 'of the textile surface 1 is hydrophobic educated. In the same way, the combination provided according to FIG. 7 is the Devices C and A are effective.

Selbstverständlich ist es aber auch möglich, mittels des Tauchbades 23 bzw. der Auftragswalze 27 eine hydrophob wirkende Flotte 21 auf die textile Fläche 1 aufzubringen, die nachfolgend aufgetragene hydrophile Paste 12 bildet in diesem Fall einen hydrophilen Film, der Feuchtigkeit aufnimmt und großflächig verteilt.Of course, it is also possible by means of the dip bath 23 and the Application roller 27 a hydrophobic acting fleet 21 on the textile surface. 1 to apply, the subsequently applied hydrophilic paste 12 forms in this Case a hydrophilic film that absorbs moisture and distributed over a large area.

Mittels der Vorrichtung D in Figur 8 wird auf die textile Fläche 1 die hydrophob wirkende Flotte 21 in der Weise aufgesprüht, daß diese nur in einen Teilbereich der textilen Fläche 1 eindringt. Durch die hydrophil wirkende Paste 12 wird somit nur der nicht hydrophob ausgebildete Teil der textilen Fläche 1 beeinflußt, so daß diese ebenfalls mit einer hydrophob wirkenden Seite 1' und einer hydrophil wirkenden Seite 1" versehen ist.By means of the device D in FIG. 8, the hydrophobic surface is applied to the textile surface 1 acting fleet 21 sprayed in such a way that this only in a portion of the textile surface 1 penetrates. Due to the hydrophilic paste 12 is thus only the not hydrophobic formed part of the textile surface 1 influenced, so that this likewise with a hydrophobic side 1 'and a hydrophilic acting Page 1 "is provided.
