ABSTRACT:
Fabrics of which the warp is sized with water-soluble polymers of acrylic acid and/or their alkali metal salts or ammonium salts, are desized by treating the sized fabric with from 30 to 300 percent by weight of water, based on the dry weight of the fabric, and separating the resulting size solution from the fabric. The recovered size solution can be directly re-used for sizing.
