Titanium dioxide delusters and gives manmade fibers a matting effect and creates a hill structure below the uppermost polymer layer that increases fiber frictional behavior. The anatase modification of titanium dioxide produces a blue-white color tone. Different fibers require different grades of titanium dioxide with different surface treatments. Inorganic coating surface treatments enhance the light stability of the system when the titanium dioxide is incorporated into the polymer. Uncoated anatase pigments are effective for polyethylene terephthalate fibers. The anatase grades used for ultraviolet sensitive nylon 6 and 66 have a rigid inorganic surface that forms a barrier between the titanium dioxide and the polymer interface. Solvents, such as ethylene glycol, water, caprolactam solution, or acetone, disperse titanium dioxide during the polymerization process.
