Abstract
A fiber is incorporated with a titanium oxide or other photocatalyst and an adsorbent comprising a phosphate of a tetravalent metal and a hydroxide of a divalent metal. The amounts of the photocatalyst and the adsorbent based on the total amount of the fiber are, about 0.1 to 25% by weight and about 0.1 to 25% by weight, respectively. The fiber may have a composite structure such as sheath-core structure in which the concentration of the photocatalyst in the sheath is higher than that of the core, and may be a fiber having a modified cross section.
