Processing of aluminum oxide fibers |
| abstract |
In the production of aluminum oxide fibers comprising dry spinning an aluminum-containing solution to produce fiber and thereafter heat treating the fiber, the improvement which comprises applying to the fiber prior to heat treatment a solution of polyvinyl acetate in a solvent which is inert to the fiber. Advantageously the polyvinyl acetate is present in its solution in a concentration of about 0.1 to 10% by weight and is applied to the fiber in about 0.1 to 3 % by weight. The spinning solution may also contain SiO2 and polyethylene oxide, and the polyvinyl acetate solution may also contain di-n-butyl phthalate as a plasticizer for the polyvinyl acetate. The fiber bundles are characterized by increased strength and resistance to breaking during further processing. |
