Some Features of the Static and Dynamic Drape Behaviour of Polyester-fibre Shingosen Fabrics

The static and dynamic drape behaviour of polyester-fibre shingosen fabrics was investigated precisely and analyzed by using the new mechanical parameters of the dynamic drapability of fabrics, such as the revolving drape-increase coefficient, D r, and the revolving drape coefficient at 200 r/min, D 200. It is shown that the value of D r of Peach Face type was small and that of New Worsted type was large. The value of D 200 of New Worsted type was larger than that for other shingosen types. On the other hand, there was no difference between each group of shingosen fabrics in node numbers and conventional static drape coefficients. In the classification by production characteristics, yarn-processing-type fabrics showed larger values of D r and D 200 than fibre-production- and fabric-finishing-type fabrics. In the classification by fibre characteristics, contractile-fibre-type shingosen fabrics showed the smallest values of D r and D 200. These features of shingosen fabrics in static and dynamic drape behaviour became more distinct by means of discriminant analysis using the parameters of the revolving drape coefficients and also the conventional static drape coefficient and node number as variables.
