A yarn monitoring device (5) includes a first sensor (51) that detects a thickness of a running yarn (Y), a second sensor (52) that detects a fiber volume of the running yarn, and a yarn quality assessing section (57) that assesses a yarn quality of the running yarn based on a thickness detection value obtained by the first sensor (51) and a fiber volume detection value obtained by the second sensor (52). |
