![]() A bundle of fibers prepared by one of the zoning methods is straightened by hand and pressed into the lower set of combs is impaled in the combs with the ends of fibers protruding, as illustrated in the left-hand side of Fig.A.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.ġ) This instrument consists of a two set of combs (top & bottom) arranged at fixed intervals to hold the fibers and keep them straight.Ģ) Here 8 top combs and 9 bottom combs are used, each comb are spaced 6 mm (¼ inch) apart except the first two bottom comb which is 3/16 inch apart.ģ) The distance from a row of bottom needles to a row of top needles is 3mm ( 1/8 inch).Ĥ) An aluminum depressor, grip, teasing needles, velvet pad etc.The separation or withdrawal of fibers in order of decreasing length.Preparation of a fringe or tuft with all fibers aligned at one end.Basically, the operation involves four main steps: The Baer sorter, the Shirley comb sorter, and the Suter-Webb sorter are the most popular method of the fiber sorter. The fiber sorter is an instrument which enables the sample to be fractionalized into length groups. There are two methods for laboratory analysis used to measure fiber length.ġ.Fibers sorter method/Array method-is much slower but results are more accurate.Ģ.Fibrograph– is the more rapid test but results are not detailed or accurate.
