19—SOME ASPECTS OF THE FRICTIONAL PROPERTIES OF WAXED AND UNWAXED WORSTED HOSIERY YARNS

Abstract

An account is given of some experiments made to elucidate the mechanism of lubrication when waxed worsted hosiery yarns run over a stationary solid surface. The effects on yarn friction of the amount of wax on the yarn, the yarn speed, the yarn moisture regain and the nature and temperature of the rubbing surface were studied, and, although several effects are at present unresolved, a general picture has been built up which fits most of the experimental results.
