    A study of the mechanism of pilling has been made by a quantitative determination of pills formed on knitted fabrics during garment wear.
    Four women students of about 20 years of age wore the same kind of cardigans for 160 hours. The estimation of pilling was made on six different parts of the cardigans by counting the number of pills and of fibers contained in each pill, and by determining the length of the fibers and the breaking condition of fibers.
    The results obtained are as follows
    1) The structures of pills are remarkably different depending on the parts of the cardigans upon which different forces act to produce pills.
    2) The structure of pills formed on the fabrics during wear is different from that produced by the Random Tumble Pilling Tester.

    A study has been made to make the characteristics of the pilling clear by a quantative determination of pills formed on the knitted fabrics in actual wear and the laundering.
    Four women students wore the same kind of cardigans for 160 hours and the cardigans underwent laundering 4 times in every 40 hours.
    The estimation of pilling was made on six different parts of the cardigans, i.e., front upper and lower parts, beck upper and lower parts, right and left elbows, by counting the number of pills and determining the length of the fibers and the breaking condition of fibers.
    The results obtained are as follows:
    1) The number of pills increases after the first laundering but the rate of increase decreases after the second and subsequent launderings.
    2) There is no remarkable difference between the structures of the pills that have undergone laundering and those which have not, but the fibers contained in the pills which have undergone laundering are not so broken.
    3) By laundering, the number of pills more increases than the change in fabric structure does,
