Abstract
The main aim of this study relies on analyzing multiple sizing machine setting on sized yarn pick-up and abrasion resistance using response surface methodology. To perform the experiment, three independent variables each at three levels (wet zone yarn tension (A) (340N, 380N, 420N), squeezing pressure (B) ((13N, 15N, 17N), and sizing machine speed (C) 30 m/min, 49 m/min and 68 m/min)) have been taken. Fifteen experimental runs have been performed using design expert 11 software (with Box-Behnken design). It has been observed from the Analysis of variance (NOVA) results of the experiment that wet zone yarn tension, squeezing pressure, and speed of the sizing machine have a significant effect on size pick-up% and abrasion resistance of the yarn. The interaction effect of BC with (p-value = .0053) and the interaction effect of AC with (p-value = .0143) have also a significant effect on abrasion resistance. Moreover, the interaction effects (AC and BC) have a significant effect on size pick-up. Regression analysis shows that wet-zone yarn tension and squeezing pressure have a negative relation with size pick-up and the speed of the machine has a positive relation. Whereas machine speed and wet-zone yarn tension have a negative relation with abrasion resistance and squeezing pressure has a positive relation.
