Abstract

L'invention a pour objet un support non tissé, le non-tissé comprend des fibres polymères organiques et est consolidé à l'aide d'un liant aqueux, le liant comprend (a) de l'amidon (b) de l'alcool polyvinylique, pouvant comprendre jusqu'à 5 % mol d'autres unités monomères, (c) le liant ne comprend pas d'agent de réticulation et (d) le liant ne comprend pas de charge. L'invention a également pour objet des utilisations du support non tissé, des procédés de production, des membranes bitumineuses et des matériaux de construction.
