Heat resistance using titanium dioxide nanofibers

An insulation blanket, comprising:

• a batting layer comprising only a plurality of titanium dioxide nanofibers having an average diameter of 10 nanometers;
• and
• a plurality of other fibers provided in a blanket body;
• wherein the plurality of titanium dioxide nanofibers have been doped with anions to form a plurality of doped titanium dioxide nanofibers;
