Abstract

Water-insoluble pigments are continuously finely dispersed in fibre-forming polymers by grinding the pigment in a sand mill or bead mill, passing the dye suspension leaving the mill into a mixing unit in which it is mixed with the molten intermediates for the polymer, then passing the mixture into a reactor at 250-300 DEG C. for polymerization or polycondensation. Suitable pigments are TiO2, Fe2O3, MgO, CaCO3, BaSO4 and the phthalocyanines. These are preferably suspended in water, or when for use with polyethylene terephthalate, in glycol. The suspension may contain 7-25 wt. per cent of pigment. Materials to be pigmented may be polyamides and polyesters deriving from e.g. caprolactam, laurolactam, capryllactam or from dimethyl terephthalate and ethylene glycol, or the monomeric transesterification product thereof. The mill may be heated up to 250 DEG C. Suitable apparatus comprises a sand or bead mill with an inlet at the bottom, and an outlet at the top leading to a closed, heatable, cylindrical mixing unit, from which an outlet leads to a polymerization vessel. In examples TiO2 is suspended in water containing sodium metaphosphate or in ethylene glycol containing alumina sol and mixed with caprolactam or an ethylene glycol/dimethyl terephthalate mixture respectively.
