Abstract

L’invention concerne un procédé de fabrication de produits d’isolation à base de fibres organiques naturelles liées par un liant organique, comprenant les étapes successives suivantes : (a) la mise à disposition de fibres organiques naturelles, (b) l’application, sur les fibres organiques naturelles, d’une composition aqueuse de liant thermodurcissable, (c) le séchage des fibres organiques naturelles imprégnées de composition aqueuse de liant thermodurcissable de manière à obtenir un ensemble de fibres organiques naturelles thermodurcissables, (d) la mise en forme de l’ensemble de fibres organiques naturelles thermodurcissables, et (e) le chauffage de l’ensemble de fibres organiques naturelles thermodurcissables mis en forme à une température et pendant une durée suffisante pour permettre la condensation des constituants du liant et la formation d’un liant insoluble.The invention relates to a process for manufacturing insulation products based on natural organic fibers bonded by an organic binder, comprising the following successive steps: (a) providing natural organic fibers, (b) application, on the natural organic fibers, of an aqueous composition of thermosetting binder, (c) drying the natural organic fibers impregnated with aqueous composition of thermosetting binder so as to obtain a set of natural thermosetting organic fibers, (d) shaping of the set of thermosetting natural organic fibers, and (e) heating the set of shaped thermosetting natural organic fibers at a temperature and for a duration sufficient to allow the condensation of the constituents of the binder and the formation of a insoluble binder.
