Description

Die Erfindung betrifft die Verwendung eines Mikrofilament-Vliesstoff mit Flächengewichten von 40 bis 180 g/m2 und einen Wasserdampfdurchgangsindex imt > 0,3.The invention relates to the use of a microfilament nonwoven fabric with basis weights of 40 to 180 g / m 2 and a water vapor transmission index i mt > 0.3.

An Sportbekleidung werden aufgrund der meist hohen körperlichen Aktivität und der damit verbundenen Thermoregulation des Körpers über eine erhöhte Schweißproduktion hohe Anforderungen an die Feuchtigkeits-Absorbtionsfähigkeit und die Feuchtigkeits-Transporteigenschaften gestellt. Die verwendeten Textilen sollen einerseits den auf der Haut austretenden Schweiß unmittelbar aufnehmen, um ein Kleben und Scheuem auf der Haut zu vermeiden. Andererseits sollen sie gute Bedingungen dafür bieten, daß der Schweiß an ihrer Oberfläche verdampft und die Wärmeisolationseigenschaften der Sportbekleidung beim Nachlassen der körperlichen Aktivität weiterhin vorhanden ist. Feuchte Textilien auf der Haut würden gerade im Erschöpfungszustand zu einem zusätzlich Energieentzug des Körpers und damit zu Unterkühlungen und einer damit verbundenen Verletzungsgefahr durch Zerrungen führen. Es besteht daher die Forderung Sportbekleidung mit einem möglichst hohen Wasserdampfdurchgangsindex anzubieten. Weiterhin werden bisher als Sportbekleidung aus unterschiedlichen Fasermischungen gewebte Stoffe eingesetzt, die aufgrund ihrer Webstruktur zum Ausfasern bzw. Ausfransen neigen und deshalb Gesäumt werden mußten. Gleichzeitig ist bei gewebten Stoffen hinsichtlich deren Festigkeit auch immer die Laufrichtung des Gewebes zu beachten. Aus der EP 0 814 188 A sind jedoch Vliesstoffe bekannt, die gewisse Nachteile der gewebten Stoffe überwinden.On sportswear are due to the mostly high physical activity and the associated thermoregulation of the body via an increased Sweat production places high demands on moisture absorption and the moisture transport properties. The On the one hand, the textiles used are said to exude the sweat escaping from the skin Immediately pick up to stick and scuff the skin avoid. On the other hand, they should offer good conditions for the Sweat evaporates on its surface and its thermal insulation properties of sportswear when physical activity wears off is available. Damp textiles on the skin would Exhaustion to an additional deprivation of energy from the body and This leads to hypothermia and the associated risk of injury lead through strains. There is therefore a requirement for sportswear to offer the highest possible water vapor transmission index. Farther have so far been used as sportswear made from different fiber blends woven fabrics are used, which due to their weave structure for fraying or They tend to fray and therefore have to be hemmed. At the same time woven fabrics with regard to their strength always the direction of the Fabric. However, nonwovens are known from EP 0 814 188 A, overcome the certain disadvantages of woven fabrics.

Bei der erfindungsgemäßen Sportbekleidung weist einen nach der australisch/neuseeländisch Norm AS/NZS 4399:1996 bestimmten UV-Schutz von 50+ auf. Weiterhin ist aufgrund der Endlos-Filamente kein Säumen erforderlich und es tritt kein Ausfasem ein. Die isotrope Filamentverteilung macht eine Beachtung der Maschinenlaufrichtung beim Zuschnitt überflüssig.According to the invention, the object is a microfilament nonwoven with basis weights of 40 to 180 g / m 2 and a water vapor passage index i mt > 0.3, which consists of melt-spun, drawn and immediately deposited into a nonwoven multicomponent continuous filament with a titer of 1.5 up to 5 dtex and contains up to 10% by weight of titanium dioxide, the multicomponent continuous filaments optionally being split and consolidated at least 80% into micro continuous filaments with a titer of 0.1 to 0.8 dtex after sportswear, as sportswear with UV light protection properties is used. The sportswear according to the invention has a UV protection of 50+ determined according to the Australian / New Zealand standard AS / NZS 4399: 1996. Furthermore, due to the endless filaments, no hemming is required and no chamfering occurs. The isotropic filament distribution makes it unnecessary to consider the machine direction when cutting.

Solche Segment-Anordnungen der inkompatiblen Polymeren im Mehrkomponenten-Endlosfilament haben sich als sehr gut spaltbar erwiesen. Die erfindungsgemäß verwendeten Mikrofilament-Vliesstoffe weisen selbst bei geringen Dicken und geringen Flächengewichten ein gutes Wärmeisolationsvermögen, eine gute Atmungsaktivität, ein gutes Feuchtigkeitstransportvermögen und angenehme hautsensorische Eigenschaften sowie damit einen hohen Komfort auf. Die "Pie" Segment-Anordnung in den Mehrkomponenten-Endlosfilamenten und die daraus gesplitteten Mikro-Endlosfilamente begünstigen die Feuchtigkeitsaufnahme-Fähigkeiten.A non-woven fabric is preferably used in which the multi-component continuous filaments a cross section with orange or "pie" have said multi-segment structure, the segments alternating each contain one of the two incompatible polymers. Besides this orange-like multi-segment structure of the multi-component continuous filaments is also a "side-by-side" (s / s) segment arrangement of the incompatible Polymers in the multi-component continuous filament possible, preferably for Generation of crimped filaments is used.
