In order to obtain a clear insight into the deformation mechanisms of fibre gel during dry spinning processes, the creeps of fibres were measured at 25°C in liquid paraffin. In this report, the relations of the breep behaviours of fibres and spinning conditions are discussed, especially by compearing the coefficients of simplest mechanical model representing fibre deformation.
The creeps of fibres were influenced very much by the solvent composition of spinning liquid. The better the solvent, the less the creeps of fibres. The higher the temperatures at dry spinning, the more the creeps of the fibres. And the maximum of retardation spectrum of fibres shifted to the farther left side than the maximum of fibres which were supnd at lower temperature. Spinning speed also influenced on the creeeps of the fibres. The less creep behavior is subject to the orientation of fibres which took place during the spinning proces.
