Abstract: The invention relates to a method for producing a hydraulically-bonded multilayer panel with at least one face layer and at least one core layer, wherein the method comprises the following steps a. introducing a flowable face mixture into a mold. The face mixture contains at least the following components i. face paste containing at least 1. hydraulic binder and 2. water; and ii. aggregate. The aggregate has a mean diameter d50 determined according to ISO 13320:2009 and/or according to EN 12620 of greater than 100.0 ?m; whereby a face mixture layer is formed; b. introducing a dry to earth-moist core mixture into the mold, wherein the core mixture contains at least the following components i. core paste containing at least 1. hydraulic binder, 2. fines, wherein the fines have a mean diameter d50 determined according to ISO 13320:2009 of up to 100.0 ?m, and 3. water; and ii.

Abstract: The method for the chlorine-free anti-felting treatment of wool comprises the steps of: f) applying a solution onto the wool, wherein the solution has an oxidizing agent based on peroxomono sulphuric acid and a tenside, g) exposing the wool to the solution in order to complete the oxidation process, h) washing out the secondary reaction products from the wool, i) treating the wool using a reduction agent and j) post-washing, wherein the steps are carried out continuously.
