    • 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.
    • 一种处理纤维材料的方法,包括以下步骤:1)提供由纤维材料组成的液体悬浮液; 2)将纤维材料的液体悬浮液在时间段T1内进行处理混合,其中处理需要足以处理纤维材料的一段时间TR; 3)在一段时间T2内将纤维材料的液体悬浮液和混合处理沉积到成形表面上以形成层并除去大部分液体; 以及4)在所述纤维材料层中施加加压的液体喷射流以在时间T3内从所述纤维材料中洗涤未使用的处理。 时间段T1,T2和T3立即连续,总共达到TR的总时间。 还公开了一种水力缠结结构,其由以下组成:1)至少一层包含纤维状纤维素材料的湿法非织造纤维网; 和2)色牢度染料赋予纤维状纤维素材料颜色,使得纤维状纤维素材料具有色牢度。
