摘      要：Background The strength of cotton fiber has been extensively studied and significantly improved through selec-tive breeding,but fiber elongation has largely been ignored,even though elongation contributes to determining the energy needed to break *** developments to calibrate the high volume instrument(HVI)for elongation has renewed interest in ***,it is not understood how best to utilize yet another fiber property which has the potential to add to the complexity of fiber *** explore a practical approach to applying elongation,cot-ton samples were tested using single fiber methods,the Stelometer,and the *** of strength,elongation,and combined properties such as modulus were *** HVI testing was shown to be sensitive enough to characterize elongation differences but unlike single fiber testing it was unable to capture within-sample *** bundle testing,like Stelometer and HVI was shown to reduce bias due to fiber *** The use of secant modulus,an intrinsic material property,allowed for one value to represent both strength and *** modulus was shown to contain more useful information than either elongation or ***-to-break was shown to be more influenced by a specific value of breaking force or elongation rather than the intrinsic behavior of the sample being *** the influence of genetics and environment on elongation,and its interaction with other fiber properties,requires additional *** modulus,by combining strength and elongation into one value,shows the potential to incorporate elongation values into fiber characteriza-tion without increasing the complexity of current fiber selection processes.
