A General Relationship between "Easy Stretch" and Break Extension for Woven and Knitted Cotton Fabrics,Including Effects of Resin Setting

Abstract

A most significant correlation between "easy stretch" (∈_∞) and break extension (∈ _b) has been observed for cotton woven fabrics, also consistent with measurements on knitted fabrics. Assuming that the reason for this correlation is an over-all similarity of the stress-strain curves, a master curve equation is derived, whose "individual" parameter is settled by force and extension at break.
