A Study of Double-rove Yarn Hairiness in the Short-staple-spinning Sector

A factorial-analysis technique is applied to study the effects of strand spacing, twist, and spindle speed on the hairiness of double-rove yarn. A wide range of twist levels and spindle speeds is covered by spinning yarns from two different types of fibres, namely, cotton and a polyester-fibre/cotton blend, in order to study the interactions of the chosen variables under the extreme conditions. The results are discussed and compared with earlier findings on singles-yarn hairiness.
