CA 2695693

The invention relates to a method for producing composite fiber materials by using at least one hydrolytic protein mixture and at least one polyamine- or polyimine-containing binder or any mixture of said binders for producing the composite fiber materials. The invention further relates to the use of at least one hydrolytic protein mixture and at least one polyamine- or polyimine-containing binder or any mixture of said binders alone or combined with at least one other binder or at least one auxiliary agent or at least one other binder and at least one auxiliary agent for producing composite fiber materials. The invention also relates to composite fiber materials that can be obtained by way of a method wherein at least one hydrolytic protein mixture and at least one polyamine binder or at least one polyimine binder or at least one polyamine-containing or polyimine-containing binder or any mixture of said binders is used for producing the composite fiber materials.

L'invention concerne un procédé pour produire des matériaux fibreux, selon lequel on utilise, pour la fabrication des matériaux fibreux, au moins un mélange de protéines présentant une action hydrolytique et au moins un liant renfermant de la polyamine ou de la polyimine ou un mélange quelconque de ces liants. L'invention concerne en outre l'utilisation d'au moins un mélange de protéines présentant une action hydrolytique et d'au moins un liant renfermant de la polyamine ou de la polyimine ou d'un mélange quelconque de ses liants, seul ou en combinaison avec au moins un autre liant ou au moins un auxiliaire ou au moins un autre liant et au moins un auxiliaire pour la production de matériaux fibreux. L'invention concerne également des matériaux fibreux pouvant être obtenus au moyen dudit procédé, selon lequel on utilise, pour la production des matériaux fibreux, au moins un mélange de protéines présentant une action hydrolytique et au moins un liant de polyamine ou au moins un liant de polyimine ou au moins un liant renfermant de la polyamine ou de la polyimine ou un mélange quelconque de ces liants.
