Study on Blended Spinning Solution Composed of Chrome Shavings Extract and Polyvinyl Alcohol

Abstract:

Chrome shavings were dechromed by methods of oxidation and the extracts were obtained in acidic or basic condition. The blended solutions were obtained by blending chrome shavings extract with polyvinyl alcohol (PVA). The optimal proportion was determined after comparing the properties which included viscosity of the mixture, mechanical properties of the blended membranes and degradation. The optimal proportion of PVA: extract (prepared with acid method) is 2:8 while solid content is 10 percent. The results of degradation test indicated that the membranes developed with the extract and PVS could be degraded in soil, trypsin solution and AS1.398 solution.
