Abstract
As the first step of pattern design by geometrical simulation of human body, sleeves and their armhole line developments are examined.
The results are summarized as follows :
1. A sleeve can be approximated to an elliptical cylinder containing an elliptical revolution at the sleeve cap. The attached surface to trunk can be considered as a plane. Thus, the pattern.of sleeve top can be drawn geometrically, and the amount of fabric shrinking on this part is possible to be calculated.
2. The interrelation between sleeve and trunk is represented by five angles. Therefore, we can examine the influence that these five angles have on the sleeve top pattern.
3. The results above-mentioned and the usefulness of geometrical simulation were confirmed practically by wearing test.
