n the goal of this study is to determine the differences between the properties of Egyptian long staple cotton, and Pima ELS cotton, to evaluate statistically the changes in yarn quality of these two kinds of cotton fibers. The considerations presented are intended for the benefit of yarn producers and textile manufacturers.

conclusion n Giza 94 and Giza 86 were found to be generally better to Supima in single yarn strength, yarn unevenness, yarn neps and hairiness. However, as fineness is required and preferred by luxury mills, Giza 94 could be regarded as comparable to Supima, although the price of Giza 94 and Giza 86 is less than Supima by 15%.
