Yarn-pileiness is the presence of fiber tips and separate loops of fibers protruding on the surface of the yarn and forming a pile. The number of fibers per unit length of yarn indicates the density of the pile. The total length of the villi is an integral estimate that takes into account both the number of fibers per unit length and their average length. The total area of ​​the villi is an integral characteristic that takes into account the number of villi, their average length and their average cross-sectional area. Methods for determining hairiness: 1. Gravimetric - a method for evaluating the hairiness of a yarn by determining the difference in mass of yarn with and without a nap; 2.optical (projection) - consists in projecting a yarn by means of an optical system onto a screen and counting the number of fibers on an image segment corresponding to 1 mm of yarn length; 3. Electrostatic - method of indirect assessment of yarn yarniness by electrostatic charge removed by a ring-shaped electrode as a result of passing villi that were charged by a high-voltage generator; 4. photoelectric - a method in which the number of villi per unit length of continuously controlled yarn is automatically recorded during optical magnification
