This study was conducted to identify the factors and the interactions which affect the maximum load of multi-thread fancy yarns. The objectives of this research was to identify the relative contribution of each factor and interaction leading to the maximisation of the tensile strength. The fancy yarns were made on a hollow-spindle spinning machine. The experimental design of this study had seven factors – with two levels each and was repeated five times. It was found that using two single yarns, instead of a similar two-ply yarn, for the core component increased the value of maximum load. The effect component contributed positively to the load only when it was a three-ply cotton yarn rather than a three-ply bamboo yarn since the former had interactions with the core and the binder. Excessive wraps reduced the maximum load. The effect of the overfeed ratio on the maximum load was weak. The manufacturing process in general had low levels of variability. This research is important because it contributes to a broader understanding to the effect of seven factors on the structure, quality, and mechanical properties of multi-thread fancy yarn.
