Bending Vibrational Properties of Polyester Shingosen Fabrics

Bending vibrational properties of polyester Shingosen fabrics were measured and analyzed by using the new mechanical parameters of bending vibration. It was shown that bending vibration of New Silky, Rayon Touch, and Peach Face type Shingosen fabrics continued longer than New Worsted type in the conventional classification, however, shorter than natural silk filament fabrics. In the classification of production characteristics, yarn-processing type Shingosen fabrics damped sooner than fabric-finishing and fiber-production type in bending vibration. In the classification of fiber characteristics, bending vibration of contractile fibers type Shingosen fabrics continued the longest and ultra-fine fibers type the shortest. Those features of Shingosen fabrics in bending vibrational properties became more distinct by discriminant analysis using the parameters of bending vibration as variables.
