In the present work, Giza 86 cotton (long staple cotton) was used to produce a different fine yarn
with counts 14.7, 11.8, 10.5, 9.8, and 7.4tex on both of compact and ring spinning frames. The
different yarn properties like, CVm%, tenacity, elongation, and hairiness were measured for both
the two type of yarns. The relative yarn quality factor RYQF was calculated to detect the more
suitable range of yarn counts for the compact spinning it was found that it ranges from 1.1 to 1.3
for range of yarn tex from 14.7 to 7.4 referring to the hairiness reduction it was found to be 31%
for yam tex 9.8 the improvement in the yarn breaking elongation was 10%, the improvement in
the yarn tenacity was 14%, while the reduction in the turns per meter in the compact spinning
was 4%. And improvement in the yam mass variation was about 5%. On the other hand it was
found that the improvement in the single compact yarn total imperfections was not statistically
significant, But generally it was found that the yarn total imperfections of the single yarn were
less for the compact spun yarns compared with the conventional ring spun yarns especially for
the fine counts
