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 Dd increase through the finishing stages, especially with relaxation. The static drape coefficient D, and revolving drape coefficient at 200 rpm D200 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 D200 appears clearly: the former increases and the latter decreases with a higher ratio of weight reduction.

Comparing and Modeling the Dynamic Drape of Four Natural-fiber Fabrics

“…Key words curve fitting, dynamic drapability, nonlinear logistic regression, tangent partition method sudaira and co-workers [4,5,[17][18][19]. They defined three stages when rotating the fabric from 0 to 240 rpm [4,5].…”

Fabric objective measurement and drape

“…The effect of high weight reduction ratio was observed with the decrease of D200 and increase of Dr. However, there were differences between samples A and B with respect to drape parameters, parameters at the final output (end of finishing stages) were similar [110].…”

“…These equations were applied in several further studies investigating drape in terms of studying different features of fabrics [57,[80][81][82][83] and the effect of finishing on fabric drape behaviour [92,110].…”

Textiles Dynamically Influenced Drapability

“…They analyzed also apart the static measuring the drapeability influenced with dynamical effect. They measured the dynamic drapeability during rotating the textile sample [1]. They found that the form of the draped sample is change from the dynamic effect.…”
