"Cotton is grown to be spun" is an old dictum among cotton processors. Spinning is considered to be a mechanical process by which a few fibres are brought and drawn together in such a manner that a cohesive twisted structure is formed. The number of fibres brought together is dependent upon the count or yarn diameter envisaged. In the process of dismantling a high density compressed bale to produce a yarn, the fibres undergo a series of processes such as opening and cleaning, individualization and parallelization, drawing, thinning down with all fibres brought together and made parallel to an imaginary yarn axis, before being inserted with a twist to form a yarn. In these mechanized operations the compressed fibres are decompressed, opened and individualized devoid of organic trash that was entangled with them. The individual fibres as a result are subjected to mechanical forces in all directions longitudinal and lateral with a preferential longitudinal pull. While preparing a homogenized drawn sliver prior to twisting, the now opened and separated fibres undergo a predominantly longitudinal drag and in both theabove major operations wastes are generated that comprise in the initial stages more organic trash and less of good fibres. In the later stages of processing on a larger measure, good fibres are discarded as waste.
