Fabric Drape and Bending Rigidity Analysis
topic
Woven fabric drape and bending rigidity are governed by weave structure through the binding frequency effect where higher binding frequency in plain weave constrains thread mobility creating stiffer fabric than twill or satin at equivalent construction, with bending rigidity measured by cantilever stiffness tests or drape coefficient from Cusick drape tester, quantifying the contribution of weave structure to the drape quality used for apparel fabric evaluation where appropriate drape is a primary design requirement.
Role
Provides the quantitative basis for selecting weave structures that achieve target drape behaviour in apparel fabric design, with the established relationship between float length and bending rigidity enabling prediction of how weave modifications will change drape quality, supporting systematic fabric engineering for drape improvement through weave modification rather than yarn count or fibre changes when the construction is the primary drape-limiting factor.
