Abstract
The article describes the results of experiments dealing with the irregularity of rayon draftcut sliver (two zone draft-cut system).
The theory described in previous reports (Part III and IV), was tested and proved by these expriments the method for experiment used is idential with the case where irregularity of carded sliver was studied.
Chief results obtained are as follows: (a) the draft-cuting of sliver caused unevenness to it quite pertinent to the “stational and normal stochastic process”. (b) in the long and the short term irregularity, each serial correlation and the relation between variance and length of sliver were obtained. (c) tuft length distribution and biased length distribution were required for the fiber which constructed the sliver. From the above results, it is recongnized that irregularity of draft-cut sliver belongs to the type of the “random sliver”.
