Factors Affecting the Friction Coefficient

Many factors affect the friction coefficient of polymer fibers. Friction coefficients shown in Table 19.1 are just some typical values. They can be used to provide some basic information on fiber-on-fiber friction, but they cannot be expected to have validity in all circumstances. 

As discussed in section 19.1.2, the friction coefficient of most materials is independent of the sliding speed. However, polymer fibers are different. The friction coefficient of polymer fibers is affected by the sUding speed. In general, at low speeds, a decrease in friction coefficient can be observed as the speed increases, but at high sliding speeds, the friction coefficient increases with increase
