This investigation provides a new method for produced dyed yarns of low cost and sufficient quality to be used for garment manufacture using some Egyptian cotton varities of different grades and consequently different Maturity percentages in combination with combed cotton waste in different ratios in open end (O.E) spininig process.  In this study we tried to find facilities looking to upgrade the disposal comber noils into medium dyed yarns. We succeeded in choosing Giza 88 cultivar combing noils to blend withboth Giza 80 and Giza 90 as a long Upper Egypt cultivars which described as coarse and short as compared with the other Egyptian cultivars and their creamy color similar to the combed waste. Measurements of fiber maturity percentage, Fiber and yarn properties, dye ability, andcolor difference propertiesof the produced blends were studied. The results obtained revealed that the best values for all the fiber and yarn characters considered that open end was the favorable system for this investigation. The results show that the micronair reading, hair weight (H.W), upper half mean, uniformity index, color strength (K/S) and color difference showed decrease as the ratio of the cotton varieties decreased.
