Studying the Linear Density of Multi-Thread Fancy Yarn Made from Natural Fibers Using the Design of Experiments

This study aims to define the factors and interaction of factors which affect the average value and variability of the linear density of fancy yarns. A robust, fractional factorial design was used and was repeated five times. It was found that the core component, the effect component and the supply and delivery speeds affected 96.5 % of the linear density value. Further, the binder, the core, the supply and delivery speeds, and the false twist affected 95% of the linear density variability. The value of this study originates from quantifying the effect of high number of factors and interactions precisely.
