Wet Spinning of Staple Fibres

Wet spinning of staple fibres has been found to yield a higher yarn strength at a given twist multiplier compared to normal spinning. [Iyer, B.V. et al., Low twist spinning, proceedings, 14thJoint Technological Conference of A TI RA, BTRA and SI Tl\4. (SITRA, Coimbatore), 1973]. In the present paper, the scope of wet spinning is discussed and the effect of certain processing parameters on yarn properties is highlighted. The variables studied include: location of wetting, presence of additives in the wetting bath and spinning tension. A tentative explanation is offered for the observed increase in strength.
