Abstract: Pigment compositions including nickel titanium yellow or chromium titanium yellow as an inorganic component together with an organic pigment component impart better gloss and/or hiding power to organic coatings containing 10% or more of the compositions if the compositions are prepared by subjecting a suspension of the components in a liquid medium to intense shearing stresses and thereafter separating the mixed pigments from the medium.

Abstract: Mixed pigments containing an organic pigment component and an inorganic pigment component imparting improved gloss and other desirable properties to organic coatings containing the same in relatively large amounts are prepared by synthesizing the organic component in the presence of the inorganic component in a liquid medium inert to the inorganic component, such as nickel titanium yellow or chromium titanium yellow.

Abstract: Filaments or filament bundles, which are conveyed by a heated gas, are crimped by treating them in a preheat chamber and crimping them in an elongate chamber from which the heated gas medium issues through longitudinal slits. A stream of cold gas is made to impinge on the outside of the lower one-third of the elongate chamber without allowing significant amounts of this cold gas to enter the said chamber. The resulting filaments or filament bundles have very good dyeing characteristics.
