Changes in the Static and Dynamic Drape Coefficients of Polyester Fabrics Through the Finishing Stages

Abstract

Static and dynamic drape behaviors of polyester woven fabrics are s died through representative finishing stages using two sets of fabrics with different conditions of relaxation and weight reduction. The node number n, the revolving drape increase coefficient Dr, and the dynamic drape coefficient D d increase through the finishing stages, especially with relaxation. The static drape coefficient D, and revolving drape coefficient at 200 rpm D 200 decrease through the finishing stages, especially with relaxation. These parameters do not change much after dyeing and raising. The effect of elaxation in a washer is stronger than in a jet-dyeing machine for these parameters. The e fect of weight reduction on D, and D 200 appears clearly: the former increases and the latter decreases with a higher ratio of weight reduction.
