DETERMINATION OF GEOMETRIC CHARACTERISTICS OF LOCAL WOOL BY STANDARD METHOD AND ACOUSTICAL INSTRUMENT

This article dealth with geometric properties of local wool, determined by the standard length method on a comb analyzer and thickness using a micrometer, and also on an acoustic PAN instrument. The results of the experiments using the standard procedure showed that the weighted average length and thickness index is higher for the wool fibers of the sheared breed of sheep. The results of the experiments on the acoustic device showed that the coarser and irregular fibers, the less the density of the fibers in the chamber, and consequently the more intense passage of the sound pulse. The result obtained on the device of PAN-1 is an affirmation of the fact that fibers of the sheared breed of sheep is coarser and irregular, so with two methods for evaluating wool fibers, similar results were obtained
