METHOD FOR MANUFACTURING PHOTOCATALYST FIBER

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a photocatalyst fiber which features good workability and is suitable for the stable production and enables an optical transmission fiber coated with a solution to be wound up on-line, and by which the strength of the oxidation titanium layer becomes strong.

SOLUTION: A mixed methanol or ethanol solution of titanium tetraalkoxide or tetrahalogenized titanium and β-diketone is applied on the surface of an optical transmission fiber, wound on-line as it is and then calcined. The manufacturing method features good workability and is suitable for the stable production because the hydrolysis is controlled by the mixing of β-diketone and the pot life is prolonged. Even if the optical transmission fiber coated with the solution is wound on-line as it is, fibers are not adhered with each other and the thickness of the membrane does not become unequal because methanol or ethanol is quickly dried. The oxidation titanium layer is hardly stripped off.
