Title: Method and apparatus for preparing inorganic oxide fiber from sol-gel composition
Inventor: CHIAACHIENGU RIN
IPC: D01F9/08
Filed: 1989-12-21
Abstract: PURPOSE: To obtain an inorganic oxide fiber from a liquid metal alkoxide sol-gel composition without using heat-treatment by preparing a dry-spinnable liquid sol of an alkoxide compound and passing the spun fiber through an ammonia- containing atmosphere to convert the fiber to non-adhesive fiber. CONSTITUTION: An alkoxide compound of formula M(OR)x (M is an element forming a hydrolyzable alkoxide; R is an organic group forming a hydrolyzable alkoxide; (x) is atomic valence of M) in a liquid sol is hydrolyzed to an extent sufficient for imparting the sol with dry-spinnable concentration and viscosity. The sol-gel composition is supplied from a pot 20 to a fiber-forming spinneret 50 and the spun fibers 80 are cured by the ammonia atmosphere in a spinning tube 60 to enable the winding of the fibers without causing mutual adhesion. The cured fibers are wound by a winder 96.
