Effects of raw cotton noncellulosic content and fiber RotorRing friction on yarn ring spinning performance

Brushwood, D.E.
In the manufacturing of cotton textile goods, especially with modern high speed processing machinery, fiber noncellulosic surface related materials and naturally occurring metals may have significant effects on yarn spinning efficiency and product quality. Chemical and physical tests were conducted on cottons originating from five domestic growing areas to determine reducing sugars, wax, total noncellulosic extractable contents, individual residual metal contents, and frictional measurements to determine possible correlations between these properties and ring yarn spinning production performance. Adjusted skein-break factor, single yarn strength, and long thin place measurements were found to be highly related to fiber ethyl alcohol surface extractable materials and the total light metal content. Yarn yellowness (+b) was highly related to metal content. Process carding wastes correlated with increased raw fiber ash residues, potassium content, and the fiber-to-fiber friction measurement.
