Patent ID: 7060160

Claim:
A process for producing a photocatalytic pulp composition, comprising: a) providing 40 to 95 wt % of pulp fibers having an average fiber diameter of 5 to 300 μm and the average fiber length of 0.1 to 70 mm; b) providing 5 to 60 wt % of titanium oxide; c) applying a stirring impact force to the pulp fibers to generate heat from the shearing force of the stirring impact force; d) drying the pulp fibers by the heat from the shearing force to reduce the water content to 3 wt % or less; e) swelling the pulp fibers into a hairy, aggregated, loosened three-dimensionally entangled fibers accompanied with the drying; f) fixing the titanium oxide to respective fiber surfaces of the three-dimensionally entangled fibers by the stirring impact force.
