Abstract
A process for finishing cellulose-containing fibrous material, in which (a) commercially available textile finishing agents are applied to the fibrous material and fixed, (b) the material is subsequently washed and dried, if necessary, and (c) the textile material is after-treated with liquid ammonia. As a result of the after-treatment with liquid ammonia, the mechanical properties of the finished fibrous material, from the textile point of view, and in particular the tear strength and the handle, are considerably improved.
