Work Done in Pulling Fibers from the Cotton Seed under Impact Conditions in Relation to Fiber Properties and Ginning Behavior

Abstract

The strength of attachment of the fiber to the seed has been pointed out to be an important parameter that may considerably affect the ginning behavior of a cotton variety. In order to simulate ginning conditions more appropriately, this property was determined by pulling out fibers from different regions of the seed with an impact tester. Fifteen Indian grown cottons belonging to different species were tested by examining fifty seeds from each species ; the percentage of seeds throwing out seed coat fragments was also counted. The relationships found to exist between mean work of pulling per fiber, on the one hand, and the energy consumed in ginning these varieties in a double- roller gin, the percentage of seeds throwing out seed coat fragments, and other fiber characters, on the other hand, are presented in this paper.
