The waxy layer forms a thin sheet over the primary wall that forms grooves on the cotton surface. Figure 2.5b shows the waxy layer surface with some smooth grooves. 2.5b), is a thin film of mostly fats and waxes. Figure 2.5 shows scanning electron microscopy (SEM) images of different layers in the figure. The cross-section of a cotton fibre is often described as being kidney-shaped. The convolutions give cotton an uneven fibre surface, which increases inter-fibre friction and enables fine cotton yarns of adequate strength to be spun. 10–12 These twists are called convolutions: there are about 60 convolutions per centimetre. Under a microscope a cotton fibre looks like a twisted ribbon or a collapsed and twisted tube ( Fig.
