Method for dyeing and/or colouring of natural protein textile fibers comprising the following steps: na) intercalation and/or absorption of dyes into lamellar solids, in order to obtain a lamellar solid intercalated with dyes, nb) polymeric coating of the surface of the lamellar solid intercalated with dyes, in order to obtain a microcapsule totally coated with polymeric film having an essentially spherical shape and a diameter ranging between 1 - 10 microns, nc) formation of polymeric pendants on the surface of microcapsules in order to anchor the microcapsules to natural protein fibers. |
