Abstract
(DE)
Ein Vliesstoff, umfassend Fasern aus einem Faserrohmaterial, wobei die Fasern zumindest eine biologisch aktive Substanz aufweisen, die zumindest teilweise in und/ oder auf den Fasern angeordnet ist, ist im Hinblick auf die Aufgabe, einen bioabbaubaren Vliesstoff anzugeben, die sich durch eine höhere mechanische Stabilität und durch eine kostengünstigere Herstellung auszeichnet, dadurch gekennzeichnet, dass das Faserrohmaterial als polymeren Bestandteil zumindest ein synthetisches Polymer in unmodifizierter und/ oder modifizierter Form aufweist, wobei das synthetische Polymer biologisch abbaubar und/ oder biokompatibel ist.
(EN)
With regard to the object of specifying a biodegradable nonwoven material which is distinguished by a higher mechanical stability and by more cost-effective manufacture, a nonwoven material comprising fibers made of a fibrous raw material, the fibers having at least one biologically active substance which is at least partly arranged in and/or on the fibers, is characterized in that the fibrous raw material has, as a polymer constituent, at least one synthetic polymer in unmodified and/or modified form, wherein the synthetic polymer is biodegradable and/or biocompatible.
(FR)
L'invention concerne un tissu non tissé, comprenant des fibres constituées d'une matière première fibreuse, les fibres comprenant au moins une substance biologiquement active disposée au moins en partie dans les fibres et/ou sur ces dernières. L'objectif de l'invention est d'obtenir un tissu non tissé biodégradable se caractérisant par une stabilité mécanique plus importante et par une fabrication moins onéreuse. Le tissu est caractérisé en ce qu'une matière première fibreuse comprend en tant qu'élément polymère au moins un polymère synthétique sous une forme non modifiée et/ou modifiée, le polymère synthétique étant biodégradable et/ou biocompatible.
