In this paper, seam tension was measured when women of three different body-types wore slacks made of three different types of fabrics and with different degrees of looseness.
The results were as follows :
1) Among the mechanical properties of a fabric, the elasticity affected most on the seam tension. In the case of the fabric that has low elongation (3.9% : elongation at the tension of 500 g/cm), the maximum tension of approximately 200 g/cm was found near the hips, and it was approximately twice as large as the one of the knitted fabric with high stretchability (18.1% elongation).
2) Concerning looseness added around hips of slacks, the maximum seam tension decreased by about a half when looseness was increased from 2 to 6 cm.
3) When slacks had the same amount of looseness, the seam tension of the slacks worn by heavyset women was 2.5 to 4.5 times as large as that of the slacks worn by slender women.
