Abstract
A method is described for predicting the inherent abrasion resistance of textile materials substantively by the use of load-elongation diagrams of mechanically conditioned specimens. Immediate and delayed deflections are discussed as they affect energy coefficient E. This coefficient is shown to be a function of: (1) low modulus of elasticity; (2) large immediate elastic deflection; (3) high ratio of primary to secondary creep; ( 4) high magnitude of pri mary creep; and (5) high rate of primary creep.
Nylon shrunk, nylon unshrunk, acetate, and viscose yarns are evaluated on the Taber Abraser, and from rate-of-destruction curves durability coefficients D are obtained. Corre lation is shown to exist between durability coefficients and energy coefficients for the four yarns.
