Influence of splicing parameters on retained splice strength, elongation and appearance of spliced cotton/flax blended yarn

Abstract

The present study aims at investigating the effect of different yarn splicing parameters on the strength, elongation and appearance of the spliced cotton/flax yarn of 74 tex linear density. Splice length, twisting time, yarn holding lever type, front plate type, untwisting pipe type and splicing nozzle profile have been taken as independent variables. A ½ fractional factorial experimental design is employed using two levels of each variable. The design and analysis of experiments are accomplished using MINITAB^® software. The results indicate that the retained splice strength of yarn is mainly affected by the splicing nozzle profile. Retained splice elongation is mainly affected by the type of untwisting pipe while the appearance of the spliced yarn is mainly affected by the splicer lever type. Furthermore, due to significant interactions, an optimal combination of splicing variables is necessary for best retained spliced yarn strength, elongation and appearance.
