  • Patent number: 4333190
    Abstract: A process for desizing a fabric web comprising the steps of: first wetting the dry size-loaded fabric with the desizing liquor separated from a previous batch of fabric after desizing, so that the fabric, and the size adhering thereto, take up water from the desizing liquor by swelling and/or solvation, thereby increasing the concentration of the desizing liquor; separating the concentrated desizing liquor from the fabric; recycling the concentrated desizing liquor to a sizing operation; desizing the wetted fabric by a continuous fresh water wash; separating the desized fabric from the resulting desizing liquor; and recycling the desizing liquor to the first wetting step.

  • 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.
