ABSTRACT
Friction between fibers inside yarns is generally important for determining the physical behavior of textiles. The tendency of cellulosic fibers to slide in a yarn directly influences the extent of fuzz formation during abrasive treatment. This paper presents a test method to determine the slipping behavior of fibers in a yarn as a function of yarn twist. Different kinds of cellulosic fibers tested with the method include lyocell, modal, viscose, and cotton. To obtain a quantitative measure, a mathematical model is established to estimate the force for fibers slipping in a yarn as a function of two basic fiber parameters, [mu
] and [alpha
]: [mu
] is the coefficient of friction of ...
