This is the second of two papers dealing with a new conceptual model o
f fiber breakage in carding. Part II deals with the development of a c
omputer simulation based on the theoretical model postulated in Part I
. Some remaining fundamental unknowns are identified and left as opera
tor choices at this stage of the model. The model shows good agreement
between predicted and measured fiber length distributions. Not only w
ill this model be useful as a predictive tool (predicting length distr
ibutions from measured fiber properties), but we will also be able to
investigate possible consequences of altering fiber properties and car
ding parameters for the resultant carded fiber length distributions.
