PROCESS FOR PRODUCING COLORED FIBROUS MATERIAL CONTAINING A DEFINITE RATIO OF CELLULOSE FIBERS, SUCH AS A PAPER AND NON-WOVEN MATERIAL AS WELL AS A COLORED FIBROUS MATERIAL PRODUCED IN SUCH A MANNER
PROCESS FOR PRODUCING COLORED FIBROUS MATERIAL CONTAINING A DEFINITE RATIO OF CELLULOSE FIBERS, SUCH AS A PAPER AND NON-WOVEN MATERIAL AS WELL AS A COLORED FIBROUS MATERIAL PRODUCED IN SUCH A MANNER
In the present invention there is disclosed a process for the manufacture of a colored fiber material, containing a certain proportion of cellulose fibers, such as paper and nonwoven. A dyestuff is applied onto reel or sheet pulp either overall material or only on part of it, whereupon the reel or sheet pulp is defibrillated and dispersed either in liquid or foam possibly together with other fibers. The fiber dispersion is thereafter applied onto a wire and dewatered, whereupon the formed fiber web, which contains a substantially even addition of colored fibers, is subjected to possible further treatment steps before drying and reeling. Dyestuff is applied to either reel or sheet pulp in the form of a strip, the width of which is less than the width of the reel or sheet pulp.
