Abstract
Procedure for improving the use properties of cellulosic material, of the type containing native or regenerated cellulose that exists in the form of fibers, yarns and fabrics, by treating the material, cellulosic with materials that can enter into a reaction with itself and cellulose, by altering the ph value and following action of acids in gaseous form, characterized in that the acid necessary for the penetration reaction or its anhydride mixed with air or an inert gas, at a temperature of 4 to maximum 90, is allowed to act on the materialºC for 3-60 seconds, which contains 2-15%, preferably 4-8% of water referred to the absolutely dry fibrous material, and which is stored after this treatment the material to be treated for 20 minutes up to 18 hours until the end of the compression reaction outside the treatment chamber filled with acid, for example in the coiled state and, if necessary, hot washing later in an alkaline bath.
