Researchers examined various yarns and spinning systems to confirm and compare the validity of weak link effects. The weak link theory suggests that materials never reach their theoretical strength due to inherent flaws in the material. The application of the weak link theory to yarn related tensile and gage properties to weak link effects. Experiments used ten different yarns manufactured by seven different systems. Standard methods determined yarn twist, packing coefficient, tensile strength, and elongation at break. A least squares method and the power law described the relationship between tenscity and gage length for most yarns, except ring spun combed yarn and flyer spun jute yarn. Weak link effects included reduced tenacity with longer gage length for all yarns and reduced tenacity and elongation at break percent with longer gage length for rotor yarn. 11 refs.
