Abstract

A process for washing textile material wherein a non-foamed washing liquor, combined with a foam-producing chemical, is applied to a continuously fed textile material, the foam is produced on the textile material by effecting alternating compression and pressure relief of the textile surface while simultaneously loosening the dirt, and finally the foam, and thus the dirt dissolved in and taken up by the foam, is removed by suction.
