Abstract: A process section which is adapted in such a way as to meet the requirements of a batch of washing, comprising textiles that are in danger of shrinking, moved during treatment in said process section in a washing drum that is rotatably arranged about a non-vertical axis while water and optionally detergent flows therethrough, wherein the amount of movement thereof corresponds to less than 5% of the possible drive time. As a result, it possible to treat shrink-endangered batches of washing despite mechanical loading by virtue of the small amount of movement of the washing drum, such that the washing can be evenly moistened with the optimum amount of water or lye, thereby optimizing the washing process for shrink-endangered batches of washing, wherein movement occurs exclusively in one direction of rotation of said drum.
