Description
technical field [0001] The invention relates to a yarn dynamic friction coefficient measuring instrument, in particular to a yarn dynamic friction coefficient measuring system. Background technique [0002] The yarn dynamic friction coefficient measurement system mainly tests the dynamic friction coefficient between the same kind of yarns, and the dynamic friction coefficient is an important physical property of yarn. The dynamic friction coefficient of the yarn directly affects the technical effect of the fabric. Studying the dynamic friction coefficient of yarn can provide a scientific basis for improving the process, selecting oil agent or slurry formula, and studying and improving the surface properties of textile equipment or yarn guiding tension parts. [0003] At present, most domestic colleges and universities, scientific research institutes and manufacturers use the imported CTT yarn comprehensive quality evaluation system and the domestic LFY-110 yarn friction coe...
