Abstract

In a yarn processing apparatus, the state of a yarn is accurately detected with a simple structure. An oil supply guide 10 configured to apply oil to a yarn formed by binding filaments spun out from a spinning unit is conductive or intermediate-conductive at least at its contact portion with the yarn. A static electricity quantity detection circuit 51 is configured to output a signal corresponding to the quantity of static electricity generated in the oil supply guide 10 due to contact between the yarn and the oil supply guide 10. When the maximum change quantity ΔE of the static electricity quantity indicated the signal output from the static electricity quantity detection circuit 51 during a period from a time point before a predetermined time to the present is equal to or less than a threshold ΔEa (S102: YES), a controller 52 outputs a first signal which indicates that the state of the yarn at the oil supply guide 10 is a predetermined state (S103). When the maximum change quantity ΔE is above the threshold ΔEa (S102: NO), the controller 52 outputs a second signal which indicates that the state of the yarn at the oil supply guide 10 is not the predetermined state (S104).
