The problem of formation, eradication and assessment of yarn faults, many years located in the center of interest of many research institutes, spinning factories and spinning laboratories and makes up an object of numerous theoretical and experimental researches. To assess deficiencies previously used labor-intensive and subjective organoleptic methods whose effectiveness can be guestioned particularly for smaller common hidden faults. Currently, devices constructed of electro-mechanical, electro-capacitive and electro-optical action counting errors for us and they are very often connected with devices that automatically cut out the place loaded with defects and reconnect the ends of the yarn. We present the history of the development of methods of measurement defects of yarns and we describe the various instrumental methods of measurement of rare occurred yarn faults.
