Abstract: In order to know the drapability of seamed knitted fabrics, four representative samples were selected. Influence of seam type and seam direction on the drape behavior of knitted fabrics was investigated through experiment. The results show that seamed knitted fabrics have greater drape coefficient, less number of folds, stable minimum amplitude of folds, and higher maximum amplitude of folds and poor uniformity of the distribution of folds. A comparison of seam types and the drape coefficients of fabrics show that drape coefficient for samples with overlock and flat-lock stitch type together is higher than for samples with overlock alone. Seam type and seam direction both have significant effect on thin knitted fabrics, however, only seam direction has significant influence on drape coefficient for thick fabrics, and the influence of seam type is insignificant.
