Abstract

The material for working apparel for a clean air environment, such as in the electronic or pharmaceutical or food industries, is a textile carrier with a bonded steam permeable film based on a polyurethane which does not swell in water, or hardly be affected by water. The textile carrier is of polyester or polyamide worked into a 30-100gm/2 fabric. The carrier fabric can be positioned on the outside or the inside of the garment. The steam permeability is at least 1000 g/m2 x 24 hrs. at 25 deg.C and Delta RP 65%. The material is weldable and can be washed and sterilised. ADVANTAGE - The material gives a hermetic seal against the release of skin or body particles and bacteria while allowing body vapours to escape and breathe. The garment can be washed and sterilised without loss of performance.

Description

Die Reinraumtechnik gewinnt zunehmend an Bedeutung. Hier nur ei­ nige Beispiele: Elektronik-Industrie, pharmazeutische Industrie, Lebensmittel-Industrie, also überall dort, wo Stäubchen und Mikro­ organismen größere Schäden verursachen können.Clean room technology is becoming increasingly important. Here only egg Some examples: electronics industry, pharmaceutical industry, Food industry, wherever there is dust and micro organisms can cause greater damage.

Die Filtration der Luft sowie die der turbulenzfreien Luftführung sind heute weitgehends gelöst, so daß als hauptsächliche Partikel­ quelle die im Raum arbeitenden Personen zu betrachten sind. Die Partikel sind im wesentlichen an den Kleidern anhaftende Partikel sowie die vom Träger selbst produzierten Partikel (in Hauptsache Hautschuppen und Bakterien). Die Anforderungen steigen ständig. Während noch vor einiger Zeit die Klasse 1000 (max. 40 000 Parti­ kel < 0,5 µm/m3) gängig war, ist heute die Klasse 100 (10× weni­ ger Partikel) Standard und man spricht von Klassen 10, 1 und so­ gar 0,1! Da ein Reinraumanzug praktisch hermetisch dicht sein muß, ist es wichtig, eine ausreichende Atmungsaktivität zu gewährleisten, wo­ bei unter Atmungsaktivität in erster Linie der Abtransport der vom Körper produzierten Feuchtigkeit zu verstehen ist. Während nun Klasse 1000 mit Anzügen aus porösen Materialien, z.B. ver­ dichtete PE-Vliese, erreicht werden kann, sind niedrige Klassen kaum bzw. überhaupt nicht mehr mit porösen Materialien erreich­ bar.The filtration of the air and that of the turbulence-free air flow are largely solved today, so that the main particle source is the people working in the room. The particles are essentially particles adhering to the clothes as well as the particles produced by the wearer himself (mainly skin flakes and bacteria). The requirements are constantly increasing. While some time ago class 1000 (max. 40,000 particles <0.5 µm / m 3 ) was common, today class 100 (10 × fewer particles) is standard and one speaks of classes 10, 1 and so on even 0.1! Since a clean room suit has to be practically hermetically sealed, it is important to ensure sufficient breathability, where breathability primarily means the removal of moisture produced by the body. While class 1000 can now be achieved with suits made of porous materials, e.g. sealed PE fleece, low classes can hardly be achieved with porous materials or not at all.

Es gibt heute kompakte, wasserdampfdurchlässige Filme, welche die Feuchtigkeit durch einen Migrationsmechanismus ableiten. Hierbei bilden in das Material einpolymerisierte hydrophile "Pakete" Stützpunkte für die Wassermoleküle, die dann von Stützpunkt zu Stützpunkt wandern, wobei die Richtung durch das Konzentrations- bzw. Temperaturgefälle bestimmt wird. Anzüge aus solchen Materia­ lien sind naturgemäß teuer und deshalb für Einweganzüge ungeeig­ net.Today there are compact, water vapor permeable films that the Discharge moisture through a migration mechanism. Here form hydrophilic "packages" polymerized into the material  Bases for the water molecules, which then go from base to Base, with the direction through the concentration or temperature gradient is determined. Suits made of such materia Lien are naturally expensive and therefore unsuitable for disposable suits net.

Um für wiederverwendbare Anzüge eingesetzt werden zu können, muß das Material jedoch waschbar und sterilisierbar sein. Die klassischen wasserdampfdurchlässigen Kompaktfilme auf Acrylatba­ sis, Polyesterbasis und Polyurethanbasis quellen in Gegenwart von Wasser sehr stark (ca. 50%!), was notgedrungen zu nachteiligen optischen Veränderungen, aber vor allem zum Ablösen vom Trägerma­ terial beim Waschen oder Sterilisieren führt. Für den gedachten Einsatz sind deshalb wasserdampfdurchlässige, quellende Materia­ lien nicht geeignet.In order to be used for reusable suits, However, the material must be washable and sterilizable. The classic water vapor permeable compact films on Acrylatba sis, polyester base and polyurethane base swell in the presence of Water very strong (approx. 50%!), Which is necessarily disadvantageous optical changes, but above all to detach from the carrier leads when washing or sterilizing. For the intended This is why water-permeable, swelling materials are used not suitable.

Es wurde nun überraschenderweise gefunden, daß sich die nach den in der DE P 39 17 336.4 bzw. DE P 39 27 185.4 beschriebenen Prin­ zipien hergestellten, nicht oder kaum quellenden Polyurethane vor­ züglich zur Herstellung von waschbaren und sterilisierbaren Rein­ raumanzügen eignen, wobei sowohl ein Trockenkaschierverfahren (z.B. DE P 38 15 720.9) als auch die klassische Umkehrbeschich­ tung angewandt werden kann.It has now surprisingly been found that the after Prin described in DE P 39 17 336.4 and DE P 39 27 185.4 zipien manufactured, not or hardly swelling polyurethanes for the production of washable and sterilizable pure spacesuits are suitable, both a dry lamination process (e.g. DE P 38 15 720.9) as well as the classic reverse coating tion can be applied.

Beispiel: Auf ein Umkehrpapier wurde zuerst ein Strich von 20 g (trocken)/m2 auf Basis von Impraperm CA 43 174 aufgetragen und ge­ trocknet. Auf diesen Film wurde sodann ein Strich von 20 g (trocken)/m2 auf Basis von Impraperm CA 43/176 aufgetragen und ein 70 g/m2 schweres PES-Gewirk naß aufkaschiert. Es resultierte ein Material, welches zahllose Kochwäschen und Sterilisierzyklen ohne nennenswerte Alterung vertrug. Das Material war verschweiß­ bar, was die Konfektion der Anzüge erleichterte, und hatte eine ausreichende Wasserdampfdurchlässigkeit (< 1000 g/m2×24 h bei 25°C, Δ RF 65%).Example: A line of 20 g (dry) / m 2 based on Impraperm CA 43 174 was first applied to a reversal paper and dried. A coat of 20 g (dry) / m 2 based on Impraperm CA 43/176 was then applied to this film and a 70 g / m 2 PES knitted fabric was laminated on wet. The result was a material that could handle countless washes and sterilization cycles without significant aging. The material was weldable, which made it easier to assemble the suits, and had sufficient water vapor permeability (<1000 g / m 2 × 24 h at 25 ° C, Δ RF 65%).

Hieraus gefertigte Anzüge wurden in einem großen Elektronik-Unter­ nehmen getestet und für sehr gut befunden.Suits made from it were in a large electronics sub take tested and found very good.
