Abstract:

In order to study on the motion of fiber during roller-drafting process and predict the irregularity of slivers, a new approach was developed to simulate the roller-drafting process based on the discrete-event simulation. The roller-drafting discrete-event simulation model was established which combines the textile draft theory and discrete theory together. The effect of parameters on output slivers unevenness was discussed. The results indicated that this model could reflect the dynamic behavior of slivers and trace the motion of each fiber during roller-drafting process. In contrast with practical test data, it proved that this model could predict the variation of output slivers unevenness though drafting. After discussing each parameter of established model, it pointed out that the fiber length and linear density of slivers were the most significant effect on roller-drafting process.

Key words: roller-drafting, unevenn, discrete-event simulation, simulation model
