The causes of misfits of nylon hosiery while being worn, especially sagging and twisting, were discussed experimentally. Our attention was paid to the four conditions of how hosiery was worn. They are as follows : the length of the clasps of the girdle, the positions of the clasps which hold hosiery around the circumference, the positions of the clasps in the welt and the amount of lengthwise stretch of hosiery.
The amount of sagging was measured by the slid-down length of a circular line on the hosiery around the knee. The amount of twisting was measured by the length of twisted portion of the hosiery times the width slid from a vertical base line along the leg. The experimental results obtained by the method of four dimensional analysis of variances are as follows :
(1) The shorter the length of clasps is, the less the misfits are made.
(2) The amount of the misfits is relatively small when hosiery is worn without strain.
(3) The amount of the misfits depends on the positions of clasps around the circumference of hosiery and in the welt.
