Res. Cent., Giza. The attained results revealed that the highest mean values of the single yarn tenacity was recorded by Giza 83 followed by comber noils and the carding waste, respectively. Single yam tenacity and elongation percentage were significantly decreased with increasing yam count and correspondingly increased with increasing twist multiplier. The fiber length was the main fiber character affecting the open-end single yam tenacity. The highest mean value of the yam evenness (C.v.%) was attained by the comber noils and the lowest mean value was gained by the carding waste. The yam irregularity was gradually increased by increasing the yarn count and twist multiplier for all studied cotton types. The carding waste spun at 25'S recorded the highest mean values of the yam evenness (C.v. %) and the lowest mean values when it was spun at 10'S. The highest mean value of the number of neps was attained by comber noils spun at 25'S with 4.0 twist multiplier, and the lowest mean values were possessed by Giza 83 cotton variety spun at 10'S with 3.6 and 4.0 twist multipliers as well as comber noils spun at 10'S with 3.6 twist multiplier.

To be more convenient for Egyptian cotton, a fiber quality index was modified and applied on the attained HVI data. The attained results revealed that all studied HVI fiber properties as well as the modified fiber quality index (mFQI) and instrumental grade (IG) were significantly affected by the storage period except, length uniformity, short fiber index, elongation percentage, moisture content and trash count. The micronaire value, maturity index, fiber length, strength, modified fiber quality index (mFQI) and instrumental grade (IG) were significantly decreased by the progress of storage up to the fifth year. Fiber yellowness degree (+b), reflectance degree (Rd), trash area and code and fiber quality index (FQI) were significantly increased by progress of storage. Generally, the first three storage periods (0, 1 and 2 years) had a little or no change in all studied traits.
