Abstract
A process for coloring nonwoven webs of fibrous material, particularly air-layed webs, in which solid, water insoluble particulate pigments are introduced and intermixed with the fibers of the web to provide the coloring thereof. An initial formed web of fibrous material has a suspension of insoluble pigment in a liquid applied thereto, is fiberized, and is reformed into a web and bonded with a binding liquid. Alternatively, the pigment may be mixed with the separated fibers after the fibrous material is fiberized and before reforming.
