  • Patent number: 4213217
    Abstract: A process for continuously washing a printed textile sheet-like structure, wherein water or a wash liquor is applied to the goods so that they entrain from 80 to 500% of water, based on the weight of the goods, the goods are then squeezed off between rollers so as to remove at least 30% of water, based on the weight of the goods, and the surface-swollen print paste residues are transferred from the goods to the roller, from which they are removed by means of water. The treatment can be repeated one or more times, and a conventional afterwash can be carried out if appropriate. The process is cheaper than conventional processes and only slightly affects the color of the unprinted areas.
