An influence of the constructing conditions and fabric properties on curtain configuration was discussed here. The results obtained were as follows:<BR>1) It was shown that the regularity of curtain pleats, the visual depth and the apparent amount of pleats were influenced significantly by the times of track length (amount of fabric) in the case of pinch pleat curtain from the results by the discriminant analysis. As for the regularity of pleats, the curtain configuration was also influenced by the bending rigidity of fabrics.<BR>2) It was shown using the quantification technique II that the constructing methods influenced the configuration. Of all the three types of curtains, i.e., pinch pleat, box pleat and gather pleat, the box pleat curtain was the most regular one in pleat configuration. The most irregular one was gather one. The visual depth and the apparent amount of pleats were much influenced by the times of track length (amount of fabric) but little influenced by the type of pleating. The visual depth and the apparent amount of pleats were influenced by the bending and shearing rigidity.<BR>3) Curtain configuration was categorized clearly into three groups by the quantification technique IV. The group 1 contained the three types of curtains with small amount of fabric (small times of track length) ; the group 2, pinch and box type curtains with medium and large amount of fabric; and the group 3, gather type curtains with medium and large amount of fabric. It was presumed that the regularity and the apparent amount of pleats were important factors to discriminate against curtain configuration.
