Abstract
A scientific, accurate, and rapid method is presented to measure yarn diameter. This method is built on pure mathematical bases without any approximation. A small sheet of parallel and equi-spaced ends is made from the yarn to be tested: Then this sheet is woven manually (as warp) with straight light wires of identical circular cross-section (as weft) in such a manner that wires reach the jamming condition and the interlacing is according to the method of plain weave. Results obtained from this prepared test specimen are number of yarn ends woven as warp, number of wires woven as weft, wire diameter, and weight of yarn interlaced with wires. For the tested yarn, only its count is required, Substituting for these five values in two simple derived formulae yarn diameter and yarn volumetric density can be obtained. The device used to perform the test is indicated.
