An experimental study of the tribological properties of hair fibres is reported, and
the effect of surface treatment on the evolution of friction and wear during sliding.
Specifically, orthogonally crossed fibre/fibre contacts under a compressive normal
load over a series of 10,000 cycle studies are investigated. Reciprocating sliding
at a velocity of 0.4 mm/s<sup>−1</sup>, over a track length of 0.8 mm, was performed
at 18<sup>o</sup>C and 40-50% relative humidity. Hair fibres retaining their natural
sebum were studied, as well as those stripped of their sebum via hexane cleaning,
and hair fibres conditioned using a commercially available product. Surface topography
modifications resulting from wear were imaged using scanning electron microscopy and
quantified using white light interferometry. Hair fibres that presented sebum or conditioned
product at the fibre/fibre junction exhibited initial coefficients of friction at
least 25% lower than those that were cleaned with hexane. Coefficients of friction
were observed to depend on the directionality of sliding for hexane cleaned hair fibres
after sufficient wear cycles that cuticle lifting was present, typically on the order
1,000 cycles. Cuticle flattening was observed for fibre/fibre junctions exposed to
10 mN compressive normal loads, whereas loads of 100 mN introduced substantial cuticle
wear and fibre damage. |
