“…Therefore, we have concluded that the difference in the projected area at the turn-around angle could be a parameter of the dynamic drape behavior of fabrics. The dynamic drape coefficient of fabrics in a swinging motion is defined as the change of projected area at the turn-around angle (17]:…”

“…where D~, = dynamic drape coefficient with swinging motion, S max = maximum projected area at the turnaround angle, Snull = minimum projected area at the tum-around angle, Ro = radius of the circular supporting stand (=63.5 mm), R j = radius of the fabric sample ( = 2 Ro = 127 mm). The dynamic drape coefficient is calculated by [ 17] ] -FIGURE 3. Relationship between calculated and measured values of the dynamic drape coefficient of fabrics with swinging motion D,,.…”

“…' Recently, we investigated the dynamic drape behavior of fabrics (Yang and Matsudaira [15][16][17]), and we defined drape coefficients in the revolving state and also with a swinging motion, proposing a relationship between those coefficients and the basic mechanical parameters obtained by the KES system. Further, we investigated the revolving drape coefficients of polyester Shingosen fabrics and reported the results quite recently [ l0], but we have not yet investigated the dynamic drape coefficient with swinging motion, hence the present investigation.…”

The static and dynamic drape behavior of polyester Shingosen fabrics is investigated using the new mechanical parameter of dynamic drapability, that is, the dynamic drape coefficient with swinging motion Dd. The Dd of the Peach Face fabric is small and that of the New Worsted fabric is large. On the other hand, there are almost no differences between each group of Shingosen fabrics in node numbers and conventional static drape coefficients. In classifying production characteristics, yam-processing fabrics show larger values of Dd than other fiber-production and fabric-finishing samples. In classifying fiber characteristics contractile fiber and ultra-fine fiber Shingosen fabrics show smaller values of Dd than irregular fiber fabrics.

“…We defined the revolving drape increase coefficient D,, which means the degree of spreading of overhanging fabrics with revolution, and the revolving drape coefficient at 200 rpm D2o«, which means the saturated spreading of fabrics at rapid revolution, and derived their regression equations [21,22]. Finally, we defined the dynamic drape coefficient with swinging motion D,,, which is considered to be similar to the human body's motion when walking, and also derived a regression equation from the basic mechanical parameters of fabrics [23]. Then we investigated the revolving drape coefficients and dynamic drape coefficient of polyester &dquo;Shingosen&dquo; fabrics and reported those characteristics quite recently [ 13,14].…”

Conventional static and new dynamic drape coefficients of silk woven fabrics are examined precisely to distinguish those features of each classified fabric by its yarn structure using our regression equations. We find that Shantung has large values of static drape coefficient D, and small node number n, revolving drape increase coefficient D,., and dynamic drape coefficient with swinging motion Dd. Chirimen is characterized by large values of Dr and Dd. Georgette has small values of revolving drape coefficient at 200 rpm, D200. Habutae has relatively large values of Ds and small n, and Dechine has relatively large values of Dr and Dd, but Fujiginu has no peculiar features. The differences between Fujiginu, Dechine, and Georgette become clear from the discriminant analysis, using the five drape parameters as variables. New dynamic drape coefficients are more useful for characterizing each classified silk fabric.

PurposeTo provide researchers with the details of developments in instruments to measure fabric drape and review the literature related to fabric drape.Design/methodology/approach – In recent years, there has been a renewed interest in investigating the aesthetic behavior of fabrics due to the developments in objective evaluation techniques. To understand drape behavior, it is essential to know how drape is measured quantitatively. This paper reviews research related to drape characteristics of fabrics, two‐dimensional instruments and analysis of drape by measuring stiffness, three‐dimensional instruments developed to measure drape, fabric mechanical properties and their influence on drape measurement, and the latest developments in the field including image analysis, the dynamic drape tester and other related research.Findings – Many instruments for measuring drape have been developed including the earliest that assessed stiffness of fabrics, later versions of drape meters and recent innovative instruments for capturing complex drape information. Even though extensive detail for simple geometric forms such as circles and squares can be provided by the newest methods, measurement of the drape characteristics of complex forms needs the consideration of researchers to extend the work on drape measurement to garments. It was also noted that there are some contradictory conclusions regarding the properties influencing fabric drape.Originality/value – This paper is offered as a concise reference for individuals beginning research in the area of fabric drape.
