Fibre migration, which is expressed by various parameters and indices, depends on fibre properties, the characteristics of the fibre assembly, and the processing conditions. The fibre properties include length, degree of elasticity, stiffness and fineness. Short, coarse and stiffer fibres move out of the core towards the sheath, while long, fine and flexible fibres move towards the core. Strongly crimped fibres are also found predominantly in the sheath. In blends of fibres with substantially different processing characteristics, preferential radial migration occurs; one component of the blend is found primarily in the core and the other component mostly near the surface. Fibres at high tensions are tried to relieve their tensions by migrating to the core. Relatively slack ones are displaced outwards. In ring spinning, the fibre tensions are generated in the delta zone where the fibres leave the nip of the front drafting rollers and pass into the twisted yarn.
