In an earlier project a process was developed on a small scale for precipitating carboxymethyl cellulose (CMC) from desizing wastewater with filter alum and recovering and dissolving the precipitate to give a solution suitable for reuse in sizing warp yarns. More extensive recovery trials have now been made on plant desizing wastewater to give sufficient material for weaving trials and for developing a practical procedure for size recovery. Weaving trials using warp yarns sized with CMC recovered from plant desizing wastewater were as satisfactory as those using warps sized with new CMC. Desizing and dyeing the woven fabrics showed no difference in hand and shade that could be attributed to the recovered CMC. The yarns were blends of polyester and cotton (65:35) and polyester and rayon (65:35). Sufficient dewatering of the precipitated CMC - to ten percent solids or higher was accomplished by centrifuging or by the use of a Dual Cell Gravity (DCG) unit (Permutit Co.) alone or, preferably, in combination with a Multi-Roll Press unit.
