Abstract: This invention relates to water-soluble/dispersible reactive imido and polyimido compounds, wherein the polyimido compounds may be selected from the group consisting of polysuccinimide compounds, polyglutimide compounds, and copolymers of thereof. The polyimido compounds comprise a water-solubilizing/dispersing moiety that provides water-solubility and/or water-dispersibility to the polyimido compound and preferably is derived from a nucleophilic moiety selected from the group consisting of amines, alcohols, phenols, thiols, and carboxylates. The present invention also pertains to a proteinaceous substrate to which the imido or polyimido compound has been covalently bonded and to a method for treating a proteinaceous substrate with the imido or polyimido compound.

Abstract: Composite textile material for the production of composite articles, consisting of a multilayer structure, the various layers being joined together by needling.It is characterized in that it comprises at least two woven layers:one of which is based on yarns with high mechanical performance (for example aramid);and the other of which is based on yarns of another kind and more particularly continuous filament glass yarns,the two woven layers being bound together by needling so that a minor part of the high mechanical performance fibres is implanted within the woven glass yarn structure.
