Method for colouring natural textile fibers

摘要

Method for dyeing and/or colouring of natural protein textile fibers comprising the following steps:
a) intercalation and/or absorption of dyes into lamellar solids, in order to obtain a lamellar solid intercalated with dyes,
b) 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,
c) formation of polymeric pendants on the surface of microcapsules in order to anchor the microcapsules to natural protein fibers.
