Elvanol T-66 is a unique copolymer grade of polyvinyl alcohol (PVA) for use on spun yarns of cotton, polyesters or blend yarns.
A lower viscosity resin than Elvanol T-25, it was developed specifically 1) to meet the demands of the new medium to high pressure slashers, in terms of better runnability and higher-solids formulations, and 2) to increase the productivity of PVA Recovery Systems based on ultrafiltration, by an improvement in desizeability and flux rates. |
