In diesem Zusammenhang sind bei Kunstledern mit Thermoplast-Beschichtungen folgende Perforier-Verfahreu bekanntgeworden: In this context, artificial leathers with thermoplastic coatings the following perforation process has become known:
a) J-u das Kunstleder werden Löcher von ca. imm gestanzt, bedeutend geringere Lochdurchmesser lassen sich praktisch aufgrund der Festigkeit bzw. Standzeit der Stanzwerkzeug nicht erreichen. Als Nachteil ist dabei anzusehen, daß die Kapillarkräfte der relativ großen Löcher ungenügend sind und daß Textiltrüger-Desehädigungen die Festigkeit des Kunstleders stark beeinträchtigen, zumal die Löcher stark schiiutzaufneliniend sind.a) J-u the artificial leather are punched holes of approx. Significantly smaller hole diameters can be used in practice due to the strength or service life of the punching tool. The disadvantage here is to see that the capillary forces of the relative large holes are insufficient and that textile defrauding damage the strength of the artificial leather greatly impaired, especially since the holes are heavily lined with protective lines are.

wiederum nachteilig ist. Ferner tritt eine Verschmutzung der Prägenadeln durch anhaftenden Kunststoff auf und ferner entsteht die Gefahr der Kunststoff-Fadenziehung.again is disadvantageous. Furthermore, the embossing needles become soiled by adhering plastic there is also the risk of plastic threading.
c) Das Kunstleder wird in eine Hochvakuuinkammer eingebracht und mittels Elektronenstrahler mikrofein perforiert .c) The artificial leather is placed in a high vacuum chamber and perforated with a microfine electron beam.
Als Nachteil ist hierbei anzusehen, daß dieses Verfahren einen sehr hoehen Kostenaufwand mit sich bringt.A disadvantage here is that this method entails very high costs.
Der Erfinder hat sich nun die Aufgabe gestellt, ein Kunstleder zu schaffen, welches wasserdampf- und luftdurchlässig und darüberhinaus auf einfachste Art und Weise herstellbar ist. Zu diesem Zweck besteht das Verfahren nach der Erfindung darin, daß das Kunstleder von der linken Seite (Trägerseite) her durchstochen wird, und zwar nur soweit, daß die Stiche nur eb,en die rechte Seite, d.h. geschlossene *-unststofipberflache, durchdringen.The inventor has now set himself the task of creating an artificial leather that is permeable to water vapor and air and, moreover, can be produced in the simplest possible way. The method according to the invention exists for this purpose in that the artificial leather is pierced from the left side (carrier side), and only to the extent that the stitches only penetrate the right side, i.e. closed * plastic surface.
Das Durchstechen des Kunstleders wird verfahrensgemäß vermittels einer erhitzten Nadelleiste durchgeführt. Die Nadelspitzen, der Nadelleiste bzw. Nadelwalze sind dabei feiner als Stecknadelspitzen ausgebildet und werden auf eine Temperatur von ca. 150 bis 200° C erhitzt.The piercing of the artificial leather is carried out according to the method a heated needle bar. The needle tips, the needle bar or needle roller are included finer than pin points and are heated to a temperature of approx. 150 to 200 ° C.

gekennzeichnet, daß dasselbe an der Bescliiehtungsoberi lache fiiikrofeine, dauerhaft bleibende Löcher, die mit dem blasen .auge kaum sichtbar sind, aufweist.marked that the same was laughing on the upper floor microfine, permanent holes that blow with the blow .eye are barely visible.
Das erfindungsgemäße Verfahren ist nicht nur für Kunstleder anwendbar, sondern gleichfalls für Kunststoff-Folien ohne Trägermaterial.The method according to the invention is not only for artificial leather applicable, but also for plastic films without carrier material.
Das erfindungsgemäße Verfahren ermöglicht also mit einem
relativ geringen Kostenaufwand eine Thermoplast-Kunsileder-Perforierung
und Thermoplast-Folien-Perforierung, welche
sich wie folgt auszeichnet:
Sehr gute Wasserdampf- und Luftdurchlässigkeit infolgeThe method according to the invention thus enables thermoplastic synthetic leather perforation and thermoplastic film perforation at a relatively low cost, which is characterized as follows:
Very good water vapor and air permeability as a result
a) mikrofeiner Löcher,a) microfine holes,
b) beliebig wählbarer Lochzahlen pro Flächeneinheit.b) any number of holes per unit area.
Zur Erläuterung des erfindungsgemäßeη Verfahrens und des nach dem Verfahren hergestellten Kunstleders ist ein Muster beigefügt, bei dem die feine Perforierung erkennbar ist, wenn dasselbe gegen das Licht gehalten wird.To explain the method according to the invention and the Synthetic leather produced according to the process is accompanied by a pattern in which the fine perforation can be seen is when it is held against the light.
