A Study on the Ease of the Total Crotch Length of Slacks

슬랙스원형의 밑위앞뒤길이 여유분에 관한 연구

The purpose of this study was to suggest the proper ease of total crotch length concerning both appearance and comfort. The research processes as follows. 1) For the purpose of obtaining the necessary ease of slacks in body movement, experimental slacks of no ease of total crotch length were made. Three college girls putting on these experimental slacks were examined on their back middle waist lines using cross-cut method. 2) Experimental slacks for suggesting the proper ease consist of 7 types; slacks CO, Wl, W3, W5, W7, C3, C5. The sensory evaluation for appearance and comfort was applied to evaluate the 7 slacks. The results can be summarized as follows. 1. As the leg-movement angle increased, the vertical space increased and the horizontal space decreased. There was negative relationship between vertical and horizontal space. And as the leg.movement angle increased, the area of space increased. The shapes of space showed the amounts of space and the direction of force by the movements. 2. The appearances of slacks C3, W3, C5 were better than the other slacks. The eases of the crotch were better than those of the waist line in appearance. And slakcs W7 was better than any other , ;lacks in comfort. When the amount of each part of eases was same, the comfort in eases of crotch was not as good as that of waist line. 3. In slacks, the proper ease of total crotch length was 3% and 5% of total crotch length.
