THE CHARACTERIZATION OF THE STATIC AND DYNAMIC DRAPE OF FABRICS

This paper discusses and establishes the static and dynamic drape of f abrics as an aesthetic property. A new algorithm is introduced, which defines more precisely the drapability of a given fabric. Experimental results show that it is more accurate to describe the different types of fabric-drape performance by using a feature vector, and this is fo und to be in good agreement with subjective assessment. A computer-bas ed vision system, the Static- and Dynamic-drape-measurement System (M- 3), was developed and made possible the application of the new algorit hm to actual fabric measurement. The results show agreement between ae sthetic judgement and subjective assessment, and consequently fabric d rape is standardised into four drape grades, ranging from high to low. The M-3 is able to relate fabric drape with mechanical properties, si mulating intelligence or expert knowledge when property change is need ed for achieving a required drape performance.
