Abstract
This study has been done to compare ring and compact yarns spun from Egyptian long staple varieties .six long staple cotton varieties were used as Giza 80, Giza 83, Giza 90, Giza 85, Giza 86 and Giza 89 ,chosen to produce 40's count yarn spun at three different twist multiplier;3.2, 3.6 and 4.0. The obtain data cleared that:- The compact spun yarns at low twist level had better yarn property values - thin and thick places, nep values, yarn hairiness, yarn evenness, yarn strength and elongation at break (%) - than the conventional ring spun yarns for long staple Egyptian cotton varieties in the same twist level .i.e. yarn strength of the compact yarn was 11%higher than the conventional ring spun yarn. In addition, Compact yarns reached maximum strength at a lower twist multiplier than conventional ring yarns. Increasing twist caused a reduction in the number of thin and thick places and yarn hairiness in both compact and ring yarns While Elongation at break and Strength values increased with higher twist for both spinning systems. The data revealed that, Giza 86 variety was superior in fiber strength (cN/tex) and Giza 90 variety was superior in yarn evenness and hairiness values than other varieties.
