Influence of preparatory processes on blend irregularities of rotor-spun blended yarns

摘要

The effect of flock blending, drawframe blending and drawframe passage on blend homogeneity and yarn quality of polyester-viscose and polyester-cotton blended yarns has been studied. It is observed that for both the blended yarns, flock blending results in better blend intimacy compared to drawframe blending. An additional second drawframe passage after flock blending has no significant effect on the index of blend irregularity. However, it improves the yarn evenness to the level of drawframe blended yarns.
