ANALYTICAL AND EXPERIMENTAL STUDY OF THE MECHANISMS OF MONOFILAMENT FIBER FRICTION Part I. A Mathematical Model for Adhesion Mechanism and a General Equation Relating Fiber Friction to Normal Load

摘要

Equations describing the relationship between frictional force and normal load for polymeric fibers (monofilaments) have been derived. Mathematical models describing the variation of area of contact with normal load were used to develop the friction equations. The equations were checked experimentally by moving monofilaments over a cylindrical surface and measuring the friction as a function of tension. The results were compared with data obtained by other workers in the field. Friction occurring between yarns at the intersection of warp and filling has substantial effect on the mechanical properties of fabrics, and may have considerable effect on stress-strain behavior. Therefore, it is necessary to take this friction into consideration in the engineering of a fibrous structure.
