Abstract
The normal method of studying the length and fineness characteristics of fibres in jute slivers and yarns involves classifying the fibres in a sample into a suitable number of length groups and determination of the frequency and linear density of fibres in all the length groups. The simplified method described in this paper requires evaluation of the cumulative frequency and linear density of fibres of one particular length only, and is hence less time-consuming than the normal method. Graphical relations and tables are provided with the simplified method to reduce the computation time, which is considerable with the normal method. The data obtained on several yarn samples of different qualities by the normal method of testing are used to show the agreement between the results arrived at by the two methods. A procedure for carrying out the tests required in the simplified method is also suggested.
