Effects of Combing-Roll Wire Design and Rotor Speed on Open-End Spinning and Cotton Yarn PropertiesSouthern Regional Research Center, New Orleans, Louisiana 70179, U. S. A.
Southern Regional Research Center, New Orleans, Louisiana 70179, U. S. A. The effects of combing-roll wire design, particularly the front angle, on lint and trash in the trash box, rotor trash, fiber breakage, fiber orientation in the rotor, and yarn properties, were investigated by means of various combining-roll and rotor speeds and different methods of cotton sliver preparation. Combing-roll and rotor speeds and sliver prepara tion had a significant effect on all the yarn properties investigated, while wire design had much less effect. Generally, combining-roll wire front (forward rake) angles of 0 and 30° yielded the poorest results, and the 15° angle wire yielded slightly better results than the other combiriing-roll wires studied.
