A theoretical model is proposed for nonstationary mass transfer from a moving fabric to a stagnant liquid hold-up in open-width washing machines. Verification of the model is established by a large-scale experiment in which concentrations of caustic soda, measured in both liquid 'and fabric, are compared with the corresponding theoretical values. Operating open-width washing machines under nonstationary con ditions appears to be economically attractive for sufficiency large values of the ratio volume of liquid hold-up of the machine to liquid flow in the fabric to be treated.
