Abstract: A device as well as a method for the treatment of ready-to-wear, textile apparel parts, particularly for the pretreatment and/or dyeing are described, according to which the ready-to-wear, textile apparel parts to be treated are arranged in cylindrical or cylinder-like fabric carrier being arranged in a preferably closable vessel, where the parts are brought into contact with a treatment bath, whereby the fabric carrier is moved within the apparatus during the treatment. Hereby the ready-to-wear, textile apparel parts are arranged in the fabric carrier as a heap of ready-to-wear, textile apparel parts. During the treatment the vessel is filled with the bath only to such an extent and the treatment bath is pumped through the fabric carrier in that way that the ready-to-wear apparel parts are displaced and particularly intermingled by the treatment bath streaming through the fabric carrier.
