Research on Reducing the Degree of COD in Wastewater during Sizing Technology

Abstract:

For the principle of green sizing, the key research on sizing technology which reduce the degree of COD in wastewater of sizing was carried out. PVA and modified starch slurry was gradually replaced by hemp pole cellulose ether and modified starch slurry, and the original formula was optimized. After valuing viscosity and COD of the slurry, several suitable formulas were chosen. Then experiments on the same batch of hemp/cotton blended yarn sizing were carried out, and the sizing enhancement rate, stretching rate and the increasing grinding rate were tested. Through the comparative analysis, the COD of hemp pole cellulose ether slurry with modified starch is lower than that of PVA slurry with modified starch. Meanwhile, with the certain compound rate, the former sizing performance is better than the later.
