<p>O.Z.0050/034040 of the disclosure: Though the recycling of sizing agents is increasingly practised, the concentration of sizing agent in the desizing liquor is insufficient for direct re-use in sizing, and hence the liquor must be strengthened. According to the invention this is achieved if the dry size-laden fabric (which may or may not have been singed) is first wetted, where relevant with simultaneous quenching, in countercurrent with the desizing liquor,i.e., size solution obtained after washing, so that the fabric and the size adhering thereto take up water from the size solution by swelling and/or solvation, thereby increasing the concentration of the size solution. This strengthened solution is subsequently separated from the fabric and recycled, whilst the fabric is only then subjected to the actual washing process to remove the sizing agent.</p> |
