Title (EN) HEAT-SEALABLE FILTER MATERIAL WITH BIODEGRADABLE POLYMERS
(FR) MATERIAU FILTRANT THERMOSCELLABLE COMPORTANT DES POLYMERES BIODEGRADABLES
(DE) HEISSSIEGELFÄHIGES FILTERMATERIAL MIT BIOLOGISCH ABBAUBAREN POLYMEREN
Abstract:
(EN) The invention relates to a filter material comprising at least two layers, where at least one layer contains natural fibres and at least one layer contains biodegradable thermoplastic fibres. Said thermoplastic fibres are chosen from among the group of aliphatic or partly aromatic polyester amides, aliphatic or partly aromatic polyesters, aliphatic or partly aromatic polyester urethanes, and aliphatic or aliphatic-aromatic polyester carbonates.
(FR) L'invention concerne un matériau filtrant comprenant au moins deux couches, au moins une couche contenant des fibres naturelles et au moins une couche contenant des fibres thermoplastiques biodégradables. Ces dernières sont choisies dans le groupe des polyamides d'ester aliphatiques ou partiellement aromatiques, polyesters aliphatiques ou partiellement aromatiques, polyesteruréthanes aliphatiques ou partiellement aromatiques, et carbonates de polyester aliphatiques ou aliphatiques-aromatiques.
(DE) Filtermaterial, bestehend aus einem mindestens zweilagigen Aufbau, wobei mindestens eine Lage natürliche Fasern und eine Lage biologisch abbaubare thermoplastische Fasern enthält, wobei die thermoplastischen Fasern ausgewählt sind aus der Gruppe der aliphatischen oder teilaromatischen Polyesteramiden, aliphatischen oder teilaromatischen Polyester, aliphatischen oder teilaromatischen Polyesterurethanen, aliphatischen oder aliphatisch-aromatischen Polyestercarbonaten.
