Fiber-jet swelling during chemical-fiber formation

  • Published:
Fibre Chemistry Aims and scope

Swelling of the jet during the formation of chemical fibers by the wet method is studied. The swelling of a jet is investigated in the shear regime during extrusion of the spinning solution through a capillary with free efflux and with stretching of a freshly formed jet in the spinning bath. It is shown that the magnitude of the swelling is determined by the viscoelastic properties of the polymer system (equilibrium relaxation time and power-law exponent) and by the conditions of extrusion of the polymer system through a capillary. Relations for determining the magnitude of the swelling and the equilibrium relaxation time are presented.
