Description:
The report gives results of a study of textile sizing and desizing in organic solvents. Properties of materials applicable as warp sizes in organic solvents were satisfactory for use as warp sizes. Properties of fabrics made from solvent-sized yarns were equal in quality to those of fabrics made from aqueous-sized yarns. Energy consumption for solvent sizing and desizing is essentially equivalent to that required in conventional aqueous systems. Costs of solvent and aqueous sizing and desizing are about equivalent if the estimates include anticipated 1983 wastewater treatment costs. Major materials cost in solvent operations is for solvent lost in the process (7.3%); the loss can be reduced by proper engineering design. Solvent sizing and desizing would virtually eliminate all of the biochemical oxygen demand (BOD) load in wastewater effluents typical in aqueous operations.
