布の曲げ特性が婦人服のシルエットに及ぼす影響

抄録

In this paper, since the heavy elastica theory is applicable in the analysis of silhouette of ladies' dress, the influence of bending length ³√B/W (where B and W are bending rigidity and fabric weight per unit area respectively) on silhouette is studied.
One-piece dresses are constructed of two kinds of fabric of women's thin dress, which have the ratio of ³√B/W of 1 to 0. 74, and are made in two sizes of 1 to 0. 74 for each kind. Sensory test, optical and actual measurements and simulation test were under taken on these specimens and the results are summarized as follows :
1) Sensory test firstly resulted that the silhouette of one-piece dress which is made of fabric of larger value of ³√B/W and of smaller size, appears harder, while that, which is made of fabric of smaller value of.³√B/W and of larger size, looks softer. Secondly, the silhouette of one-piece dress which is made of larger value of ³√B/W and of larger size looks the same as that which is made of smaller value of ³√B/W and of smaller size. 2) It was found that silhouette of ladies' dress is closely related with both ³√B/W and size, and that the result has good agreement to that of the sensory test. 3) In order to obtain the same silhouette of one-piece dress among different sizes, it is necessary to construct dresses in the same ratio of value of ³√B/W as the ratio of size.
