Textile and chemical fiber industry is another important applications of titanium dioxide . Chemical
fiber with titanium dioxide mainly as delustering agent. Pepple commonly use anatase due to the
anatase is softer than rutile. Chemical fiber with titanium dioxide generally do not need surface
treatment, but some special chemical fiber need to surface treatment in order to reduce the photochemical
reaction of titanium dioxide and avoid fiber dropped by the photocatalytic of titanium dioxide.
