    摘要: 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.
