The Surface Characteristics and Friction Properties of PTFE Yarn

Abstract:

To discuss the surface characteristics and friction properties of PTFE yarn, the longitudinal structure and cross section were analyzed, it were investigated that the influence on friction coefficient of running speed, guide material and initial tension on ring spinning for producing PTFE film yarn. The results show that the longitudinal section of PTFE yarn was regular cylinder, the cross section was polygon, the yarn surface was very smooth, not easy to absorb dust, PTFE yarn had very good self-cleaning function. The friction coefficient of PTFE yarn was decreased at first with the increase of running speed but increased later, and the friction coefficient of PTFE yarn was reduced with the increase of initial pressure. The friction coefficient between PTFE yarn and plastic was very small, it can be said that plastic was the best guide material for ring spinning of PTFE yarn. Introduction
