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.
