There are plenty of methods used to quantify the quality of cotton fiber and it is known that there are differences in the principles of these methods, as well as the quantitative methods differ in the degree of accuracy and being appropriate to quantify fiber quality. Therefore, this study was carried out to compare between some quantitative methods used as a quality criterion of fiber of Egyptian cotton varieties. The most important results were: The Multiplicative Analytic Hierarchy Process (MIAHP) was in the highest values of Spearman rank correlation (Rs) at the two carded ring counts 30 and 40 Ne in comparison of fiber quality index (FQI), Premium-Discount Index (PDI) and Spinning Consistency Index (SCI). The same trend was Grade Factor Analytic Hierarchy Process (GFAHP) in comparison of Grade Factor (GF), this is due to the incorporation of proper criteria weights of cotton fiber properties in both of Multiplicative Analytic Hierarchy Process (MIAHP) and Grade Factor Analytic Hierarchy Process (GFAHP) by using the analytic hierarchy process, and this in turn is more accurate and appropriate than having the same weight for all the cotton properties involving both of GF and FQI. Quantification of cotton fiber quality by using MIAHP and GFAHP should reflect achievable level of endproduct quality representatives in skein strength and these findings emerged through Spearman rank .
