AN EXPERIMENTAL STUDY OF CHITOSAN WET SPINNING PROCESS

This work investigates, mainly from modelling point of view, the process of chitosan fibers formation by coagulation from aqueous solution using sodium hydroxide solution as coagulant (wet spinning). The experimental data were obtained using a spinning laboratory plant. The modelling and simulation study of the chitosan hydrogel wet-spinning conducted to results in an acceptable concordance with the measured data on a laboratory unit. This is proving that the proposed model can be used in the calculation of the coagulation step of the fiber formation process by wet spinning.
