Abstract
A new method to decide an amount of an ease across a collar of a Kimono is described in this paper. According to this method the amount of the ease is fixed by a body style, thickness of the collar, characteristics of a fabric and a collar style. Influences of the fabric, the collar style and a measure of an agarikurikoshi on the amount of the ease have been discussed. The results obtained are as follows :
1) The smaller a Young's modulus of the fabric in the bias direction, the larger the amount of the ease. But it hasn't so much effect on the ease.
2) The amount of the ease becomes smaller in the order, a standard collar, U-type collar and V-type collar.
3) The agarikurikoshi has little effect on the ease.
