Multiple response optimization of sizing machine settings and sized yarn tensile properties using advanced method of experimental design

On a loom, the warp yarns experience exceptionally high mechanical stresses and strains, as well significant abrasion from friction. As result, yarn breakages cause loom stoppages and, hence, production quality interruptions. To mitigate this problem, should be treated with thin, strong film of an appropriate adhesive. The aim study is therefore, to investigate effect sizing machine parameters on tensile properties optimize sized properties. Design expert 11 software Box-Behnken design has been employed research, analyze results experiments, responses. In three factors, each at levels (wet zone tension (A) (340, 380, 420 N), squeezing roller pressure (B) (13, 15, 17 speed (C) (30, 49, 68 m/min), response variables (gain strength, loss elongation, stretch), are considered. 15 samples have produced various combinations given values measured for sample. It observed that wet gain stretch, elongation. According regression analysis, strength negative relationship positive pressure. other case, both wet-zone elongation stretch. At 340 N tension, 13 pressure, 51 m/min speed, optimum (32.7 cN/tex), (18.5%), stretch (1.4%) were obtained. methodologies in revealed empirical between factors responses, interaction effects multiple optimizations. optimized result can applied improve loom’s efficiency significantly.
