Comparison between Three (3) New Cotton Varieties (A, B and C): Technological Characteristics of the Fibers and its Spinnability Index

In Mali, several studies and research have been undertaken in favor of varietal improvement of the cotton plant, which until then have focused on, among other things, the improvement of varietal species, the increase in productivity and the technological quality of fibers. The variety choice is now made at national organizational structure on the cotton sector from production up to commercialization level on the basis of variety trials conducted by national research. The choice of varieties is made according to the objectives of the moment and the requirements of the spinners. The general objective of this study is to evaluate the technological characteristics of the fibers of the cotton varieties G3 A, G3 B and G3 C with a view to their transformation through the spinning. The technological characteristics of the new varieties are generally good for the samples analyzed. In fiber technology, they are at the same level as the values sought or deemed appropriate by the textile industry. However A variety is the best in terms of fibers technological parameters (it is ranking in the first floor for four (4) parameters on six (6) parameters. Therefore its spinnability index is the best (SCI =139). Otherwise, concerning waste quantity it shows the least (ME % = 3.74) compared to two others. Finally, with regard to the varietal improvement objectives, the study showed that these must be clearly identified from economic and technical concerns, to lead to the development of specifications specifying the limits of the physico-technical parameters beforehand determined.
