Abstract
A low-cost, in-line process for treating a fibrous web with a lotion is provided. The process generally involves passing a web through a nip formed by a pair of opposed surfaces, where one of the surfaces has been treated with a lotion having a penetration hardness greater than 5.0 mm. As the web passes through the nip, the lotion is transferred from one of the opposed surfaces to the surface of the web. In certain instances, the web may have a textured surface and only a portion of the web's textured surface is treated with a lotion.
