Abstract:
The stress-strain properties, the tensile-recovery behavior, and the response to re peated tensioning (cycling) of sixteen staple yarns were investigated. Three man-made (Fiberglas, viscose, acetate) and seven synthetic (nylon, Orlon,² Dacron,3 Dynel, Saran, polyvinyl chloride, Kuralon) textile materials were tested at standard conditions using the Instron Tensile Tester. The tensile recovery was obtained by measuring the three elongation and work com ponents. The total work of rupture was divided into the immediately recoverable work, creeping work, and unrecoverable work absorption. Dynamic tests were carried out by extending the yarns in 50 cycles to 80% of their elongation at break and measuring their response during and after this procedure. A comparison was made between tensile properties of staple yarns and corresponding multifilaments of the same material. Cycling tests were found useful in evaluating those tensile characteristics which are significant for the performance of yarns in service. It was attempted to interpret the behavior of yarns in repeated tensioning and flex abrasion from their known tensile properties.
