Three lint grades and three spinning wastes (flat card strips, comber waste and spinning filter waste) in two of Egyptian cotton cultivars i.e Giza 75 and Giza 81, as well as the second grade of polyester were used in this study. The higher grade has the best fiber, yarn and fabric properties. The flat card strips and comber waste contain a high percent of immature fibers which cause in poor of fiber properties as well as yarn and fabric characters. The comber waste has the lowest single strand strength. Ring spinning gave the highest values of mechanical properties of yarn and fabric. Open-end spinning showed the best values of the yarn evenness.
