The invention relates to a method for determining laundry properties in a tumble dryer (1) which comprising a horizontally rotatable laundry drum (2) and a resistance measurement device (3) with two measurement electrodes (4) and also a control unit (6). The method comprises that: a) the electrical resistance R between the measurement electrodes when the laundry drum (2) is rotating is measured depending on the time t; b) the electrical resistance RR(t) which is measured depending on the time t is averaged over a prespecified time period [delta]t and registered as a time-dependent average resistance value Rm(t); c) the time-dependent average resistance value Rm(t) is evaluated in respect of an initial average resistance value Rs and/or a change over time [delta]Rm/[delta]t in the time-dependent average resistance value Rm(t); d) the initial average resistance value Rs determined in step (c) and/or the change over time [delta]Rm/[delta]t in the time-dependent average resistance value Rm(t) determined in step (
