The effect of various factors, such as the nature of the fiber and the titanium dioxide content, on the abrasive properties of textile yarns has been studied, using a scanning electron microscope. Polyamide and polyester continuous filament yarns produce regular grooves on the surface of knitting needles, but cellulosic yarns give rise to much smoother areas of wear, with some striations. The effect of titanium dioxide on the abrasive properties of the yarn is marked with polyamide yarns, but less significant with the other textile fibers.
