Objective evaluation of artificial furs for tactile comfort

The resistance of piles when fingers move on artificial furs is important for tactile comfort. To evaluate the resistance of piles, a simple device for measuring the horizontal force FH of artificial furs was developed and attached to a KES-SE surface tester. The horizontal force (FH) generated when a bar moves on the surface was measured at different vertical displacements from the base for samples with different pile lengths. A hand evaluation test was carried out to find the relationship between FH and subjective parameters, namely, smoothness, comfort and ‘shittori’. Subjective hand evaluations showed that fur mobility was directly related to the sensations of smoothness and comfort. The average horizontal force included the interfiber friction force caused by changing the pile density during bar movement. FH is related to fur mobility and is one of the useful indicators of the tactile comfort of furs.
