- Title
Reclamation of Polyvinyl Alcohol Using Vacuum Extraction.
- Authors
Perkins, Warren S.
- Abstract
The application of vacuum extraction technology In the reclamation of polyvinyl alcohol (PVA) size materials was studied. The objective was to determine if PVA could be extracted from wet greige goods at a concentration high enough to justify reuse of the extracted solution. Several grades of PVA were tested using two different techniques to wet the greige fabrics prior to extracting the fabric at a vacuum slot. Polyvinyl alcohol was reclaimed from a commercial fabric, and the properties of the reclaimed size were evaluated by testing films cast from the reclaimed material and by measuring properties of yarn sized with the reclaimed material.
