Abstract
It is difficult to decide experimentally how best to arrange the numerous holes to be made on the spinneret of acetate dry spinning. As a method of theoretical inquiry, we attempt to determine the suitability of the arrangement of holes by using a purely geometrical and practical parameter which is useful for expressing the degree of inter-hole obstruction of evaporation. A comparison of calculated results with experiments showed no contradiction.
We believe this mathematical treatment suggest a way for deducing the best arrangement of the holes on an acetate spinneret.
