Abstract:
A hygiene or wiping product includes at least one ply of a fibrous web containing cellulose fibers and having a graphical pattern of at least first and second areas. The ply contains a coloring compound providing a coloration of the ply in the first area. The coloring compound is at least partly chemically destroyed in the second area so that the ply is less colored in the second area than in the first area. A method for producing such a ply includes the steps of providing a fibrous web containing a coloring compound, which provides a uniform coloration in at least a portion of the web, and applying a bleaching agent to a part of the colored portion of the web to at least partly decolor the web in the part generating a pattern of at least first colored and second less colored areas.
