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

Abstract

This study primarily analyzed the dynamic drape coefficient of four natural-fiber fabrics at speeds of 0—450 rpm. A tangent partition method was used to divide the drape coefficient curve into four regions, characterized as drape coefficient increment initial growth, fast growth, slow growth and dynamic stable regions. The ANOVA test was used for validation. The dynamic drape coefficients of these four natural-fiber fabrics were then compared. The order of the drape coefficient of these fabrics changed three times in the fast growth region and then remained unchanged throughout the slow growth and dynamic stable regions. The order of the static drape coefficient of fabrics could not represent the drape coefficient of fabrics in dynamic performance. Therefore, a linear model, a growth model and a nonlinear logistic model were used to analyze the dynamic drape coefficient curve fit, and the F-test was used for validation. The results showed that the nonlinear logistic function could be used to fit the drape coefficient curves throughout the static state and the dynamic stable region.

Fabric objective measurement and drape

“…Lin et al [58]studied the dynamic drapeability of four natural fabrics at a wider range of revolution speeds (0 -450)rpm for a sample disc with 18 cm diameter. Images were captured for fabrics tested at 25 rpm regular intervals.…”

Fabric and Garment Drape Measurement - Part 2

“…Plots of experimental drape coefficients showed that the order of the fabrics was dependant on the revolution speed at which the DC was measured. Their order was changed three times in the fast growth stage and returned to the initial growth order and became stable at the two periods following the fast growth (slow growth and dynamic stable) [23].…”

“…Lin et.al. analyzed the dynamic drape coefficient of four natural-fiber fabrics at speeds of 0-450 rpm [13]. A linear model, a growth model and a nonlinear logistic model were used to analyze the dynamic drape coefficient curve fit, and the F-test was used for validation.…”
