ABSTRACT:
A process for treating a fibrous material which includes the steps of: 1) providing a liquid suspension composed of fibrous material; 2) intermixing the liquid suspension of fibrous material with a treatment over a time period T.sub.1 --wherein the treatment requires a period of time T.sub.R sufficient to treat the fibrous material; 3) depositing the liquid suspension of fibrous material and intermixed treatment onto a forming surface to form a layer and removing a substantial portion of the liquid, over a period of time T.sub.2 ; and 4) applying pressurized jets of a liquid to the layer of fibrous material to wash unused treatment from the fibrous material within a period of time T.sub.3. Periods of time T.sub.1, T.sub.2 and T.sub.3 are immediately consecutive and amount to a total period of time at least as great as T.sub.R. Also disclosed is a hydraulically entangled structure composed of: 1) at least one layer a wet-laid nonwoven web containing fibrous cellulosic material; and 2) colorfast dye imparting color to the fibrous cellulosic material such that the fibrous cellulosic material is colorfast.
