Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Agriculture - Department of Animal Production Summary: In the present study, 700 Kg of Barki wool was collected from Desert Research Center, Egypt, to study the effect of subjective grading system and blending with polyester on some wool and yarn characteristics of Egyptian Barki Sheep. Wool was graded subjectively into raw, fine and coarse, and then each grade was blended with 0%, 15%, 25%, 35% and 45% of polyester. The measured traits were analyzed using the SAS GLM procedure and differences between means were tested using Duncan's multiple range test. Correlations were also calculated using the data coming from wool grades and the first blend, which contain 100% raw wool. Staple and yarn strengths were higher in both coarse and fine grades compared with raw wool. Staple elongation of fine grade reached 3 times of coarse grade and twice as much as raw grade. Also, in 100% wool blend, yarn elongation of fine grade was twice as much as both coarse and raw grades. Among different grades and blends, fine grade had the highest yarn friction followed by other grades. Generally, adding polyester to coarse and fine grades leads to improve yarn strength compared with raw grade. Adding 15% of polyester caused the highest improvement among other percentages. Correlations among traits were also discussed
