A process for washing and rinsing substrate sheets, in particular of nonwoven fabric or needle-punched felt sheets, is used after previously carried out activation and electroless chemical metallization. The pores or the surfaces of the substrate sheets are adequately freed from the salt residues of the metallizing solution. In this process, the textile material is wound spirally onto the rotor of a drum, and the washing or rinsing water is fed into the textile material via a hollow shaft of the rotor. The washing, rinsing, and spinning operations proceed in one apparatus, resulting in an appreciable savings in the amounts of water supplied. The entire washing and spinning operations in the drum lends itself to complete automation.
