The cotton is one of the most important crop in the fiber group due to its volume and valued production. This study was conducted with the aim to characterize a ginner regarding physical and physiological quality of seeds and some technological qualities of the cotton fiber. The ginner was made with the following components: cleaner, cylinder saws, cylinder brushes, condenser, and a three-phase electric motor of 3 CV to turn on the equipment. The experimental design was a completely randomized factorial (2 x 2 x 2 x 4), with two cotton cultivars (BRS 187 and BRS Safira 8H), two types of saws (11¾" and 12"), two cleaning process (with and without cleaner) and four rotations (500, 550, 600 and 650 rpm) and four replications. During the processing of seeds, types of saws and cleaning processes did not affect the physical and physiological quality of seeds. Meanwhile, in the technological characteristics of the cotton fiber, the ginner showed efficient performance with the rotation of 550 rpm, using the 12" saws and cleaning device turned activated (cleaner).
