Die Erzielung einer ausreichenden Luft- und Wasserdampfdurchlässigkeit ist bei Kunstleder eines der wichtigsten Anliegen, da ohne diese Eigenschaften die Verwendbarkeit für manche Anwendungszweeke in Frage gestellt ist* Is ist daher schon auf mannigfachen Wegen versucht worden, zu luft- und wasserdampfdurchlässigen Kunstledern zu gelangen. Bekannt ist das Einlagern wasserlöslicher Salze in die als Schichtbildner verwendete Kunststoffmasse und deren anschließendes Herauslösen nach erfolgter Verfestigung der Schicht. Auch durch Ireibmittelzusätze und andere Schaumbildner läßt sich eine Porosität der KunststoffscMeht erzielen. Diesen vorbekannten luft- und -wasserdampfdurchlässigen Kunstledern haften jedoch gewisse Mängel an, die teils in ihren nicht voll befriedigenden Gebrauchseigenschaften, teils in der zu geringen Wirtschaftlichkeit ihrer Herstellung liegen* Gegenstand der vorliegenden Heuerung ist nun ein neuartiges luft- und wasserdampfdurchlässiges Kunstleder, das frei von denAchieving sufficient air and water vapor permeability is essential for artificial leather one of the most important concerns, since without these properties the usability for some Applications is called into question * Is has therefore already been tried in a variety of ways become air and water vapor permeable To arrive at artificial leather. It is known to store water-soluble salts in the plastic compound used as a layer-forming agent and then to dissolve them out after the layer has solidified. Also by means of blowing agent additives and others Foaming agents can be used to achieve a porosity of the plastics material. These previously known However, artificial leathers that are permeable to air and water vapor have certain defects, some in terms of their unsatisfactory performance characteristics, and some in the fact that their production is too low lie * The subject of the present hiring is a new type of air and water vapor permeable Artificial leather that is free from the

Das neue Kunstleder ist dadurch gekennzeichnet, daß es aus einem Trikotgewebe oder -gewirke als !rager und einer damit fest verbundenen Kunststoffschicht, die an einzelnen laden und Fasern, des Gewirkes,.die sie gewissermaßen ummantelt, verankert ist und iie zahlreiche, durch Aufreißen gebildete durchgehende Poren aufweist, besteht·aforementioned disadvantages. The new synthetic leather is characterized in that it is made of a tricot fabric or knitted fabric as! rager and a plastic layer firmly attached to it that attaches to individual loads and fibers, of the knitted fabric, which it as it were encased, anchored and iie numerous, by tearing open has formed through pores, consists
Uaeh einer vorteilhaften Ausführung der !Teuerung ist das neue luft- und wasser dampfdurchlässige Kunstleder noch zusätzlich mit einer Verstärkung versehen. Diese kann wahlweise aus einer offenzelligen Schaumstoffschicht oder einem weitmaschigen G-ewebe sowie aus einer Kombination beider bestehen. Das neue Kunstleder ist in diesem Falle also drei- bzw. vierschichtig aufgebaut, wobei die Oberschicht aus der neuartigen porösen Kunststoff beschichtung besteht. Hieran sehließt sich bei dreischichtigem Aufbau entweder die offenzellige Schäumstoffschicht oder das weitmaschige G-ewebe als Grundschieht an. Wählt man einen vierschichtigen Aufbau, so kommt die offenzellige Schaumstoffschicht zwischen dem Trikotgewebe oder -gewirke und dem weitmaschigen G-ewebe, das in diesem Falle die Grundschicht bildet, zu liegen. Das weitmaschige Gewebe besteht zweckmäßig aus reißfesten Fasern, beispielsweise solchen auf der Basis von Polyamiden oder Polyestern. Die Verwendung eines reißfesten weitmaschigen Gewebes als Trägerschicht empfiehlt sich besonders dann, wenn das luft- und wasserdampfdureh-Another advantageous embodiment of the inflation is the new air and water vapor permeable Synthetic leather also provided with a reinforcement. This can optionally be made of an open-cell foam layer or a wide-meshed G-ewebe as well as a combination of both. In this case, the new synthetic leather has a three- or four-layer structure, with the The top layer consists of the new type of porous plastic coating. See this In the case of a three-layer structure, either the open-cell foam layer or the wide-meshed one G-ewebe as basic. If you choose a four-layer structure, it comes the open-cell foam layer between the tricot fabric or knitted fabric and the wide-meshed one G-ewebe, which in this case forms the base layer, to lie. The wide-meshed one Fabric is expediently made of tear-resistant fibers, for example those on the Based on polyamides or polyesters. The use of a tear-resistant, wide-meshed fabric as a carrier layer is particularly recommended when the air and water vapor permeability
