“…Since the fiber particle to be tneasurerl is much shorter than 9 x 10; ciii, Equation 3.caii be written pAL(9 x 105) L Denier = where L = average fiber Iength (cni) and A L = volume of the fiber particle (~1 1 1~) . Substituting the identity in Equation 1 into Equation 4 results in a11 expression relating denier to threshold level t:…”

Conclusion po = 1.165 X g/cm3 110 = 15 ciii/sec. From these esariiples, we see the limitation of this method, but it should be still valuable in the determination of the tension acting on a melt fiber.

AbstractFiber-diameter and denier distributions of various size tows have been determined with the Coulter Counter, an instrunient consisting of a sensing unit and a digital counter. The methods developed for sample preparation, instrument operation, and efficient data reduction are described. A critical comparison of the results with results of other denier inensuring techniques is made, and the advantages and limitations of the method at present and its future potential are discussed.
