The ﬁber sorter is an instrument which enables the sample to be fractionalized into length groups. The Baer sorter, the Shirley comb sorter, and the Suter-Webb sorter are the most popular method of the fiber sorter. Basically, the operation involves four main steps: Preparation of a fringe or tuft with all ﬁbers aligned at one end. The separation or withdrawal of ﬁbers in order of decreasing length. The preparation of a sorter diagram by laying the fibers on a black velvet pad in decreasing order of length, the ﬁbers parallel and their lower ends aligned along a horizontal base line as shown in Figure. The analysis of the sorter diagram.
