Fiber elongation is an important physical property of textile fibers. Elongation determinations were initially performed on individual fibers. This is no longer practical. Individual cotton fibers vary considerably in character and the testing ofsingle fibers is very time consuming. Current testing methods use a bundle of fibers. The bundle elongation test used by the High Volume Instruments has been dependent upon calibration cottons of 'known' elongation. This article presents a method thatutilizes the mechanics of the breaking mechanism and a mechanical reference to determine the elongation of a cotton bundle.
