The following results were obtained after developing and conducting tests on items set up for evaluation of the cotton machine system development by self-test and requesting an external authorized testing agency to conduct the test. In technology development, the re-materialization of cotton fragments reduced manufacturing costs by 40%, and the recovery rate was over 95% as a result of the cotton loss test for the development of cotton machine systems. The Feed Roller Speed Control performance test resulted in a revolution of 5 rev per minute.
