Effects of Interfacing Type on Shear And Drape Behavior of Apparel Fabrics

Abstract

Shear stiffness values for sample fabrics representing a range of weights and yarn types were determined on the Kawabata Tensile and Shear Tester and correlated with drape values measured on a specially designed drape tester. Shear behavior was also determined after application of fusible and nonfusible woven and nonwoven interfacings to the sample fabrics. Interfacing type signif cantly affected the shear stiffness of the composites. The nonwoven interfacings, because of their high shearing resistance, contributed to composite shear stiffness in an additive fashion. The nonwoven character was more important than the presence offusible resins in determining composite behavior. For woven interfacings, however, fusible resins significantly affected shear behavior by increasing the stiffness of the interfacing as well as of the face fabric. For both fusible and nonfusible woven interfacings, large differences in the shear stiffness of the componentfabrics also influenced the composite shear behavior.
