Abstract

Cotton yarns of 32.81 tex with a twist multiplier of 4.0 were spun using six different drafts ranging from 86.54 to 140.63 on a Suesson Open-End Spintester from slivers that had been carded with and without crushrolls. The static pressure in the spinning chamber was held at two levels equivalent to 7.9 × 10−5 and 5.8 × 10−5 Pa. The spinning was performed at turbine speeds of 30,000, 45,000, and 60,000 rpm. Trash extracted by the machine was weighed after each spinning condition. Statistical analyses of data collected from yarn physical tests were performed. Analyses of variance results and graphical presentations are given. The results of the investigation indicate that increasing turbine speed deteriorates yarn physical properties significantly, but also results in more trash extracted; lower drafts yield better yarn evenness and fewer imperfections, but result in less waste extracted than the higher drafts; static pressure in the spinning chamber equivalent to 7.9 × 10−5 Pa results in better yarn evenness and fewer imperfections, but also decreases the trash removal efficiency; and the use of crushrolls at carding slightly lowers the tensile properites of the spun yarn. With respect to trash extraction, the visible foreign matter content of the slivers was lowered by the use of crushrolls; the data normalized to the foreign matter content show only a small effect due to the use of crushrolls at carding on the trash extraction efficiency of the system.
