Laminated photocatalytic pulp paper and process for producing the same as well as paper sstring and process for producing the same and paper product comprising the paper string

摘要

An object of the present invention is to provide a laminated photocatalytic pulp paper having a variety of uses such as a filter material, a packaging material, a construction material and the like, which has the antibacterial property, the bad smell degrading property and harmful substance oxidatively degrading property, is useful for use in air treatment, water treatment and soil treatment and, at the same time, can improve the photocatalytic activity effect itself of titanium oxide. According to the present invention, there is provided a laminated photocatalytic pulp paper characterized in that a wastepaper pulp is laminated on a photocatalytic pulp composition in which 40-95 wt% of a pulp and/or a paper having the water content of 3 wt% or less, an average fiber diameter of 5-300 mu m and an average fiber length of 0.1-70 mm are blended with 5-60 wt% of titanium oxide, and a paper string comprising this pulp paper.
