Weaving Parameter Interaction Effects and Design of Experiments
topic
Weaving parameter interaction effects arise when the impact of one parameter on fabric quality or loom efficiency depends on the level of another parameter, with known interactions including the warp tension and speed interaction on break rate, the shed height and warp tension interaction on shed opening quality, and the weft tension and weft density interaction on fabric weight, requiring designed experiments with factorial or response surface methodology designs that reveal interactions that one-variable-at-a-time experimentation misses.
Role
Demonstrates the necessity of designed experiments for weaving process optimisation in preference to the sequential one-variable optimisation that fails to identify parameter interactions, with the recognition of interactions being essential for finding the true optimum in the multi-dimensional parameter space where independent single-variable optimisation finds local optima that are not globally optimal from the interaction effects that were ignored in the single-variable approach.
