Subject of the invention is a nonwoven, wherein the nonwoven fibers are organic polymer fibers, and wherein the nonwoven is consolidated with an aqueous binder, wherein the binder comprises protein and a polyphenolic compound from natural origin. Preferably, the nonwoven carrier is highly suitable for producing bituminous membranes. Subject of the invention are also uses, methods, bituminous membranes, binders and building materials, which are related to the nonwoven carrier. L'invention a pour objet un non-tissé, les fibres non tissées étant des fibres polymères organiques, et le non-tissé étant consolidé avec un liant aqueux, le liant comprenant une protéine et un composé polyphénolique d'origine naturelle. De préférence, le support non tissé est hautement approprié pour la production de membranes bitumineuses. L'invention concerne également des utilisations, des procédés, des membranes bitumineuses, des liants et des matériaux de construction, qui sont liés au support non tissé.
