Fractionation of nylon fibres using a vertical settler
Based on theoretical analysis, a continuous vertical settler was found capable of fractionating fibres according to their length. Fractionation experiments confirm the theoretical predictions. Under the extreme dilution used in this study, there was no effect of feed consistency. The performance of fibre fractionation decreased with an increase in the overflow stream flow rate. Fibre fractionation performance improved for a larger fibre diameter. A theoretical model was developed to simulate fractionation in the continuous vertical settler and it agrees fairly well with the experimental results.
