length, fibre denier and fibre type on the migration and blend characteristics
of rotor spun yarns has been studied. 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
