| Friction and friction build-up cause yarn breaks as textile yarns come into contact with different surfac-es during the manufacturing processes. The interaction between yarn and the other elements such as guides, needles, and machine parts will cause friction. The Yarn Friction Meter is a small, hand held, portable instrument that measures the coefficient of friction very quickly and accurately. It provides feed-back on effects of wax, paraffin or sizing materials on the overall yarn friction values. |
