This paper is concerned with the optimization of a double-rove spinning process in the short staple spinning system, using Box and Hunter's technique of a central compound rotatable design. The influences of strand spacing, twist, and spindle speed on yarn tensile and regularity properties are discussed.Double-rove spinning is becoming more popular because of tremendous cost savings [5,9]. Although there is a considerable amount of work on the properties of double-rove yam produced on the short staple spinning system [ 3,4,8 ], the optimization of doublerove spinning parameters using a factorial analysis has not been so far reported in the literature. Our work concerns the optimization of the three most important double-rove spinning parameters: strand spacing, twist multiplier, and spindle speed. We have used the design developed by Box and Hunter [ 2 ] , which was used by Barella et al. [ I ] in optimizing the rotor spinning process. The yam quality is assessed in terms of its tensile and regularity properties. ExperimentalIn this paper, the zero spaced double-rove yam is considered as a control yam and the others are spaced double-rove (SDR) yarns. The experiments to produce SDR yams were planned according to the rotatable design of Box and Hunter [2] ] for three variables: strand at UNIV OF PITTSBURGH on June 19, 2015 trj.sagepub.com Downloaded from
