Cotton fibres contain naturally occurring non-cellulosic materials such as sugars, wax, metals and other organic species that may influence fibre characteristics, i.e. physical and chemical properties, yarn processing efficiency as well as product quality. Chemical and physical tests were conducted on raw cottons from different growing areas of Pakistan to determine the effect of different depositions of these materials on fibre properties, spinning performance and yarn properties. The present research study was planned to explore the locations effect upon the non-cellulosic content of raw...
