FIBROUS FORMATION CONTAINING ACTIVE SUBSTANCES, A METHOD FOR THE PRODUCTION THEREOF, AND USE OF THE SAME

摘要

The invention relates to fibrous materials containing a fibrous proportion and, optionally, a particle proportion. The fibrous materials also contain a proportion of one or several active substances for liquid treatment. At least one active substance is provided in the form of a coating and/or impregnates at least one portion of the fibers and/or particles which form the fibrous material, and is distributed in the fibrous material in a defined inhomogeneous manner such that the active substance is provided in a predetermined quantity in a predetermined proportion of the fibers and/or particles which form the fibrous material. In addition, the active substance is not provided in another predetermined proportion of the fibers and/or particles which form the fibrous material or is provided in a quantity which differs from the first predetermined proportion of the fibers and/or particles which form the fibrous material. The invention also relates to fibrous materials which are at least bound to a depot for the active substance so that the active substance is first released when using the fibrous material according to determination, is attained on the fibrous material, and is thus available for the liquid treatment.
