Titanium oxide composite fibers and method for producing same

A method for producing a titanium oxide composite fiber, the titanium oxide composite fiber including:

• fiber;
• titanium oxide;
• and
• an inorganic binder,
• the inorganic binder being firmly fixed to the fiber,
• the titanium oxide being firmly fixed to the inorganic binder so that the titanium oxide is firmly fixed to the fiber via the inorganic binder,
• the method comprising the steps of:
• adding titanium oxide to slurry containing the fiber;
• and
• generating the titanium oxide composite fiber by synthesizing the inorganic binder in the slurry to which the titanium oxide has been added,
• at least part of the inorganic binder containing at least one inorganic compound selected from (i) an inorganic salt containing at least one of:
• at least one metal selected from magnesium, barium, aluminum, copper, iron, and zinc;
• and silicic acid and (ii) metal particles containing the at least one metal.
