Classification: CPC C  B | IPC B  C

Claim 8:
9. A process for the manufacturing an assembly of fibers or particles characterized in that a combination of (i) an aqueous composition of a polyphenolic macromolecular compound which bears a multitude of phenol or polyhydroxybenzene radicals or catechol radicals (dihydroxybenzene), selected from lignosulfonate salts and condensed tannins and mixtures thereof, and (ii) an aqueous composition of a polyamine functional compound comprising primary and/or secondary and/or tertiary and/or quaternary amine functional groups, wherein the polyamine functional compound is selected from peptides and proteins, in their natural or denatured state, is applied sequentially or simultaneously onto a collection of fibers or particles such that the ratio of polyphenolic macromolecular compound to polyamine functional compound ranges from 98:2 to 50:50 w %, or an aqueous binder composition according to claim 1 is applied onto a collection of fibers or particles, in that the coated fibers or particles are gathered in an assembly and subjected to curing conditions whereby the polyphenolic macromolecular compound and the polyamine functional compound are caused to react to form a macromolecular binder and water is evaporated.
