    In this study, fiber compositions, colors, light reflection characteristics, and light transmission properties for the commercial shoji papers were investigated. The results were as follows.
    1) Although the shoji paper predominantly composed of broussonetia-kazinoki (Kozo) contains local aggregations of fibers, the density of the paper was smaller as compared with the shoji paper composed of pulp and/or other fibers.
    2) The commercial shoji papers often show a bluish whiteness according to the use of a fluorescent agent. The fastness of the agent to sunlight was not so excellent.
    3) The screening effect of shoji paper can be evaluated by measuring its haze value obtained from the transmittance ratio of light.
    4) Machine-made shoji papers using rayon, synthetic fibers, binding agents as well as wood pulp are usually produced under hot pressurized conditions. Thus, the surface of the papers tends to become smooth. Accordingly, the machine-made shoji papers reflect light more directly and luster artificially as compared with hand-made shoji papers prepared from broussonetia kazinoki (Kozo).

    In order to evaluate fabric handle of top sheet of disposable diapers objectively, primary hands for the top sheet were selected and defined from the opinions of consumers (mothers) who are using disposable diapers for their children. Four primary hands such as “NAMERAKASA”, “SOFUTOSA”, “KOSHI” and “FUKURAMI” were defined for the top sheet and they could ex-plain 87% of the descriptions used for hand evaluation. “NAMERAKASA” is considered to be a peculiar primary hand of top sheet of disposable diapers. Objective evaluation equation (DPC M-1) of the top sheet using those basic mechanical parameters was developed by stepwise re-gression method with high accuracy and small errors.
