It is observed that differences in fibre length, fibre denier and fibre type do not affect the blending potential of the rotor spinning machine. The long fibres in a length difference blend and the coarse fibres in a denier difference blend showed tendency to concentrate at the surface of the yarn. However, no significant segregating tendency of the above constituents was observed when the length and denier differences in the respective blends were small. In a polyester/viscose blend, polyester fibre showed inward migration.</span>
