The basic requirements for evaluation of absorvency in disposable diapers were pursued by using 8 kinds in the market, (5 of which are made chiefly of pulp; 3, chiefly of paper) by comparing the state of contained water in various sizes of samplings with various amount of load on. 1. At least 10 sampling materials larger than 4cm × 4cm should be taken from each kind of diapers for the examination. 2. The diaper made chiefly of pulp is better than that chiefly of paper, 3. The correlation of thickness and the amount of water contained is very great: Without load r=0.999 With 50g/cm^2 r=0.995 The correlation of thickness of soaked material and the percentage of water in the material is smaller than the above case: Without load. r=0.656 With 50g/cm^2 load r=0.876 4. According to the qualities of pulps used, spread of moisture and the amount of contained water are different. In making disposable diapers, various combination of materials shoulb be devised: inside, e.i. the side the material touches the skin of the wearer, spread of moisture shoud be made smaller; outside, the amount of contained water should be less in the same unit of area. Of the two kinds of pulps examined, RAYFLUFF-Q (2.2cm) should be used under the surface of the inside, while RAYFLOC-J, with longer fiber (2.6cm) under the surface of the outside.
