The Effect of Blends between Some Egyptian cotton Varieties and Introduced Cottons on Technological and Spinning Characters

Abstract

Two Egyptian long staple cotton varieties (Giza 86 and Giza 80) were blended with imported Greek and Russian cottons at 100, 75, 50, 25 and 0 percent of Egyptian cotton component in blend. The objective of the study was to determine the effect of blending, with different percentages, on fiber and yarn properties. The study was set up as split plot design, where the varietal blends were allocated to the main plots and the blending percentages assigned to the subplots. The correlation between blended fiber properties and yarn characteristics varied according to varietal blend, but, generally, showed negative correlation between single yarn strength and fiber micronaire value (-0.54), and between yarn uniformity and blended fiber elongation (-0.58).
