Abstract
Process for the manufacture of a colored fibre material, containing a certain proportion of cellulose fibres, such as paper and nonwoven. A dyestuff is applied onto reel or sheet pulp either on the whole material or only on part of it, whereupon the reel or sheet pulp is defibrated and dispersed in liquid or foam possibly together with other fibres. The fibre dispersion is thereafter applied onto a wire and dewatered, whereupon the formed fibre web, which contains a substantially even addition of colored fibres, is subjected to possible further treatment steps before drying and reeling. A fibre material manufactured according to the process is also disclosed. If only part of the pulp fibres are colored, a mottled color impression of the material is obtained.
