Abstract

The protective gloves, permeable to steam but impermeable to water, are coated with a polyurethane membrane which is elastic and pore-free and does not swell in water. Pref. the polyurethane membrane is reinforced by a lightweight knitted material, pref. of 35-100 g/m2, and the PU layer is 20-200 microns thick, pref. 35-100 microns. The water vapour permeability, measured by a Lissy (RTM) appts. is 1000-5000 g/m2/ 24h, and pref. 2000-4000 g/m2/24h. The gloves are produced from two webs, welded together with an insert of man-made fibres, such as ultrasonic welding of two paper webs with the applied film. The material can also be prepared by immersion or spraying. ADVANTAGE - The cladding provides tightly-fitting stretch gloves which can 'breathe' but are impermeable to water.

Description

Eine der angestrebten Funktionen des klassischen Gummihandschuhs ist der Schutz der Haut vor Nässe bzw. aggressiven Flüssigkeiten und Stoffen. Andere Anwendungen beruhen auf hygienischen Anforde­ rungen. Schließlich kommt es in der Reinraumtechnik darauf an, die Emission von Hautpartikeln zu unterbinden. Der Schutz gegen aggressive Chemikalien bleibt auch heute noch dem schweren Gummi­ handschuh vorbehalten, während für eine Reihe von sonstigen Anwen­ dungen auch sehr dünne, meist aus Polyäthylen oder PVC gefertigte Handschuhe Eingang gefunden haben. Ihr Erfolg beruht nicht nur auf dem sehr günstigen Preis, sondern auch auf dem noch vorhande­ nen "Fingerspitzengefühl". Es ist ein Nachteil der genannten Hand­ schuhe, daß sie zwar dicht sind und somit auch vor Nässe schüt­ zen, aber gleichzeitig auch wasserdampfundurchlässig sind, so daß der Schweiß nicht verdunsten kann. Oft versucht man, durch einen extra großen Zuschnitt das Entweichen der Feuchtigkeit zu ermögli­ chen. Abgesehen davon, daß man für bestimmte Arbeiten anliegende Handschuhe braucht, ist der Abtransport der Feuchtigkeit auch hier ungenügend, und es kommt zu den sogenannten Waschfrauenhän­ den, welche durch den längeren Kontakt der Haut mit Kondensat ver­ ursacht werden.One of the desired functions of the classic rubber glove is the protection of the skin against moisture or aggressive liquids and fabrics. Other applications are based on hygienic requirements stanchions. After all, in clean room technology it depends prevent the emission of skin particles. Protection against Even today heavy chemicals remain aggressive chemicals glove reserved while for a number of other applications also very thin, mostly made of polyethylene or PVC Gloves found entrance. Your success is not just based on the very reasonable price, but also on the still existing "Sensitivity". It is a disadvantage of the hand mentioned shoes that they are tight and therefore also protect against moisture zen, but are also impermeable to water vapor, so that the sweat cannot evaporate. Often you try to get through extra large cut to allow moisture to escape chen. Apart from the fact that you have to do certain work Needs gloves, the moisture is also removed insufficient here, and so-called washerwoman hangings occur those that ver through long contact of the skin with condensate be caused.

Es wurde versucht, mittels mikroporösen Membranen und mikroporö­ sen Beschichtungen "atmungsaktive" wasserdichte Handschuhe herzu­ stellen. Die bekannteste mikroporöse Membran ist die Teflon-Mem­ bran der Firma Gore. Sie ist kaum elastisch, nicht verschweißbar - die Ränder müssen verklebt werden - und relativ wenig mecha­ nisch beanspruchbar. Das Material ist deshalb eher für einen In­ nenhandschuh geeignet. Mikroporöse Beschichtungen verlangen einen verhältnismäßig schweren Träger und sind schon aus diesem Grund nicht für dünne Handschuhe geeignet. Seit einiger Zeit gibt es auch wasserdampfdurchlässige Folien, die hauptsächlich im Frei­ zeitsektor Eingang fanden. So wird beispielsweise eine Polyester­ folie angeboten, die aber mangels Elastizität für einen eng anlie­ genden Handschuh nicht geeignet ist. Zudem ist die Wasseraufnahme und die damit verbundene Quellung sehr hoch (50%), und die mecha­ nische Stabilität ist im gequollenen Zustand eher gering. Neuer­ dings gibt es auch wasserdampfdurchlässige Polyurethan-Beschich­ tungen, und zwar sowohl im Wasser quellend als auch nicht quel­ lend. Das nicht quellende Material war dazu bestimmt, eine leich­ te atmungsaktive Regenbekleidung herzustellen, die die Beschich­ tung an der Außenseite hat.It was tried using microporous membranes and microporous coatings "breathable" waterproof gloves put. The best known microporous membrane is the Teflon membrane bran of the company Gore. It is hardly elastic, cannot be welded - The edges have to be glued - and relatively little mecha nically resilient. The material is therefore more for an in  suitable for gloves. Microporous coatings demand one relatively heavy carriers and are for this reason alone not suitable for thin gloves. There has been for some time also water vapor permeable films, mainly outdoors time sector found. For example, a polyester film offered, but due to the lack of elasticity for a tight fit glove is not suitable. In addition, the water intake and the associated swelling very high (50%), and the mecha nical stability is rather poor when swollen. Newer However, there is also water vapor permeable polyurethane coating tions, both swelling in water and not swelling lend. The non-swelling material was designed to be lightweight te to manufacture breathable rainwear that covers the tion on the outside.

Es wurde nun gefunden, daß sich das in Wasser nicht quellende, aber wasserdampfdurchlässige Polyurethan-Beschichtungsmaterial auf viererlei Weise zur Herstellung von eng anliegenden elasti­ schen Handschuhen ausgezeichnet eignet.It has now been found that the water that does not swell but water vapor permeable polyurethane coating material in four ways to make tight-fitting elasti gloves.

Man kann:One can:

  • 1. auf abweisend ausgerüstetem Papier die Polyurethan-Lösung streichen und ohne den Film vom Papier abzuziehen (der Film ist als solcher wegen seiner hohen Elastizität nicht leicht zu handhaben) diesen durch das Papier hindurch in der gewünschten Handschuhform verschweißen. Besonders bewährt hat sich die Ul­ traschall-Verschweißung. Hierbei wird das Papier mitgeschnit­ ten. Das am Handschuh leicht anhaftende Papier erleichtert sehr das Verpacken. Eine geeignete PU-Lösung wird z. B. von der Bayer AG unter der vorläufigen Bezeichnung Impraperm 43174 angeboten. Auf diese Weise wurden Schichtdicken von 20-60 µ erreicht. 1. the polyurethane solution on repellent paper and without removing the film from the paper (the film as such is not easy to because of its high elasticity handle) through the paper in the desired position Weld the glove shape. The Ul ultrasonic welding. The paper is cut The paper that is slightly stuck to the glove makes it easier very packaging. A suitable PU solution is e.g. B. from from Bayer AG under the provisional name Impraperm 43174 offered. In this way, layer thicknesses of 20-60 µ reached.  
  • 2. nach klassischem Umkehrverfahren produzieren. In diesem Fall wird auf Papier zuerst der Deckstrich aufgebracht und getrock­ net. Zu dem anschließend aufgetragenen noch nassen Haftstrich läßt man ein PA- oder PES-Gewirk von 30-50 g/m2 zulaufen. Dank der textilen Verstärkung kann das Material sehr gut ohne Papier gehandhabt werden. Zwei solche Bahnen können - mit dem Textil nach innen oder nach außen - in der gewünschten Form thermisch verschweißt werden. Es könnten Schichtdicken (PU-Schicht) von 35-60 µ erreicht werden.2. produce using the classic reverse process. In this case, the top coat is first applied to paper and dried. A PA or PES knitted fabric of 30-50 g / m 2 is added to the still wet adhesive coat applied subsequently. Thanks to the textile reinforcement, the material can be handled very well without paper. Two such sheets can be thermally welded in the desired shape - with the textile inside or outside. Layer thicknesses (PU layer) of 35-60 μ could be achieved.
  • 3. Tauchen. Auch hierfür eignet sich das bereits erwähnte Impra­ perm 43174 sehr gut, allerdings muß die Rheologie der PU-Lö­ sung geändert werden. Es ist dem Lackfachmann bekannt, daß die lästige Bildung von Tropfen und "Rotznasen" zur Vergangenheit gehören, wenigstens bei hochwertigen Lacken. Durch bestimmte Zusätze bildet man im Lack eine "Struktur", eine Art Gitter, die das Fließverhalten ändert. Bei der genannten PU-Lösung er­ reicht man den gewünschten Effekt durch Zusatz von beispiels­ weise 2-3% MPA 60 X von Kronos Titan oder von 1-1,5% Bentone 38 der gleichen Firma. Das erstgenannte Produkt ist ein Poly­ olefin, das zweite ein Organoschichtsilikat vom Hektorit-Typ. Das Einarbeiten ist den betreffenden Merkblättern zu entneh­ men. Auf diese Art ist es erstmals gelungen, elastische, was­ serdichte, aber wasserdampfdurchlässige Schutzhandschuhe durch das Tauchverfahren herzustellen. Daß die Tauchform vorbehan­ delt werden muß, z. B. mit einer Siliconkautschukdispersion, ist dem Fachmann bekannt.3. Diving. The impra already mentioned is also suitable for this perm 43174 very good, but the rheology of the PU-Lö solution can be changed. It is known to the paint specialist that the annoying formation of drops and "snotty noses" to the past belong, at least for high quality paints. By certain Additives form a "structure" in the lacquer, a kind of grid, that changes the flow behavior. With the PU solution he mentioned you reach the desired effect by adding examples 2-3% MPA 60 X from Kronos Titan or 1-1.5% Bentone 38 of the same company. The first product is a poly olefin, the second an organic layer silicate of the hectorite type. The incorporation can be found in the relevant information sheets men. In this way it was possible for the first time to elastic what protective gloves that are waterproof but permeable to water vapor to manufacture the immersion process. That the diving form is reserved must be delt z. B. with a silicone rubber dispersion, is known to the person skilled in the art.
  • Auf die beschriebene Art wurden Schichtdicken von 50-200 µ erreicht, ohne daß bei der Trocknung Probleme auftraten (Bläs­ chen). Ein 50 µ dicker Film hatte nach der Lissy-Methode eine Wasserdampfdurchlässigkeit von 3600 g/m2 24 h. Die genannten Schichtdicken und Produkte sind Beispiele und keineswegs ein­ schränkend. In the manner described, layer thicknesses of 50-200 μ were achieved without problems during drying (bubbles). A 50 µ thick film had a water vapor permeability of 3600 g / m 2 for 24 h using the Lissy method. The layer thicknesses and products mentioned are examples and are in no way restrictive.
  • 4. Der Vollständigkeit halber soll noch eine vierte Möglichkeit erwähnt werden: Spritzen. Je nach Vorrichtung müssen Lösungen mehr oder weniger eingedickt werden, wofür die selben Ver­ dickungsmittel wie unter Punkt 3. gut geeignet sind. Leider sind Materialverluste unvermeidbar.4. For the sake of completeness, there is a fourth option be mentioned: syringes. Depending on the device, solutions have to be found are more or less thickened, for which the same ver thickeners as in point 3 are well suited. Unfortunately loss of material is inevitable.

In all den beschriebenen Arbeitsweisen wurde mit Lösungen gearbei­ tet. Das verlangt, daß die abgedampften Lösemittel entweder adsor­ biert (Aktivkohle) oder vernichtet werden (Nachverbrennung). Um­ weltfreundlicher sind Dispersionen, die sich insbesondere für das Tauchverfahren gut eignen würden, aber (noch) nicht verfügbar sind. Grund dafür ist die etwas kompliziertere (aber durchaus mög­ liche) Herstellung, aber vor allem weil kein Bedarf bestand.In all of the working methods described, solutions were used tet. This requires that the evaporated solvents either adsor beers (activated carbon) or destroyed (afterburning). Um Dispersions that are particularly suitable for the Diving methods would work well, but are not (yet) available are. The reason for this is the somewhat more complicated (but definitely possible liche) production, but mainly because there was no need.

Schließlich soll noch eine dritte Substanzklasse erwähnt werden, die im zunehmenden Maß eine Rolle spielen wird: die unter dem Namen High Solids bekannten Systeme, mit welchen ebenfalls wasser­ dampfdurchlässige Beschichtungen hergestellt werden können. Wäh­ rend bei den üblichen Lösungen bzw. Dispersionen Moleküle des fer­ tigen Kunststoffs vorliegen, enthalten die High Solids präpolyme­ re Systeme, die noch aneinandergekoppelt werden müssen. Aufgrund der kleineren Moleküle können High Solids ohne oder mit nur wenig Lösemittel verarbeitet werden, sofern ihre doch noch recht hohe Viskosität nicht stört. High Solids lassen sich verschneiden und etwas emulgieren. Sie eignen sich insbesondere für das Tauchver­ fahren, wobei allerdings beim Erhitzen kurz vor der Vernetzung ein Viskositätsminimum auftritt, dem Rechnung zu tragen ist.Finally, a third class of substances should be mentioned, which will play an increasing role: that under the Names of high solids known systems, with which also water vapor permeable coatings can be produced. Wuh rend with the usual solutions or dispersions molecules of fer existing plastic, the high solids contain prepolyme systems that still need to be coupled together. Because of of the smaller molecules can be high solids with little or no Solvents are processed, provided their are still quite high Viscosity does not bother. High solids can be blended and emulsify something. They are particularly suitable for diving drive, although when heating shortly before crosslinking a minimum viscosity occurs which must be taken into account.
