Abstract:

In order to realize prediction of combing quality and intelligent design of combing process, combing processing was simulated by computer for a cotton lap with specified fiber length distribution (number) using Monte Carlo stochastic simulation method, and it was obtained that cotton web form in different stages of a work cycle and number CV value of outputting web. Simulating results under different parameters were discussed. The results show that number CV values of outputting web are lower when forward motion timing is 14.5 and 15.5 index; the number CV value increases with the increase of the noil gauge; and when feeding length increases in the region of 4.7 - 5.9 mm, the unevenness of outputting web becomes worse. The simulated results are in good agreement with previous experiment data. The simulation processing is more suit for combing process research of cotton lap whose fiber length distribution changes frequently.
