Abstract: Fibre profile plays an important role in OE rotor spinning. The yarns made from a trilobal fibre perform no better than the yarns made from a circular fibre in respect of twist deviation, tensile parameters and mass irregularity. The yarn hairiness is a more serious problem with circular fibres. The spinning of rotor yarns with a low twist factor and rotor speed produces yarns within the acceptable hairiness limit. Yarns with trilobal fibres pick up more dye than the yarns with circular fibres. The dye uptake decreases with the increase in tex twist factor but the decrease in the uptake of dye reduces with the decrease in polyester fibre denier.
