Abstract
Fibrous glass substrates are coated with a substantially unhydrolyzed, hydrolyzable mixture of a silicon alkoxide and a titanium alkoxide and the coating is then hydrolyzed and cured. This provides the glass substrate with a long flex-life, abrasion resistant coating making the fibers of utility for use in forming filter bags.
