摘要：
A method of colouring or coating a plurality of individual fibres 10 comprises: (a) applying a formulation comprising (i) water and optional emulsifier； (ii) a condensation-curable film-forming amino-silicone pre-polymer 12, and (iii) a cross-linking agent 14, and optional catalyst 16, for curing the pre-polymer； (b) effecting partial condensation curing of the pre-polymer on the external surface of the fibres； (c) subsequently washing the fibres with a rinsing liquid to produce a washed silicone film； and (d) applying an aqueous dispersion containing a polymeric material having neutralized acid moieties and at least one surfactant, to produce a polymeric film that coats the silicone film. Preferably the neutralized acid is a neutralized ethylene-acrylic acid (EAA) copolymer, in which at least one pigment is embedded. Also disclosed is a plurality of fibres, each comprising: (a) a core fibre； (b) an at least partially cured amino-silicone film enveloping and adhering to the core fibre； and (c) a coating including a polymer film having neutralized acid moieties, at least partially enveloping the partially cured amino-silicone film. A method of removing a film of EAA neutralized copolymer linked to a cured amino-silicone film is also disclosed.
