Influence of Selected Process Variables on Worsted Compact Yarn Properties

Original language description

In the work the influence of small change of draft and negative air pressure in condensation zone of drafting unit of compact spinning machine on selected worsted yarn properties is studied. Yarns (80% WO, 20% PA) were produced on a compact spinning machine equipped with the compression zone type Suessen EliTe from three rovings of various fineness using two levels of air negative pressure. Main draft ratio on the compact spinning machine was changed to the yarn of the same count be produced. To eliminate influence of roving irregularity on final yarn mass irregularity, machineirregularity was calculated and evaluated. Results confirmed that higher negative air pressure positively influences all observed properties of tested yarn (mass irregularity, number of faults, yarn hairiness, tenacity and breaking elongation) whereas increasing draft ratio up 20 % has statistically significant effect on thin places, number of neps as well as on yarn mass irregularity, but in this case from the point of practice, the difference is insignificant. On the other hand, draft has positive effect on yarn breaking elongation and, in much lesser extent on yarn tenacity. According to results, the level ofnegative air pressure is more significant factor which affects yarn property compared to observed range of draft ratio.
