The step of dividing the wool yarn wound on the cutting spacer to form a wool rod;

The step of twisting the wool rod and two core yarns to form chenille yarn;

During the winding of a predetermined amount of chenille yarn on the spindle, the output rotational speed of the main motor and the yarn motor is increased at least once.

Usually, after the chenille machine runs for a period of time, as the core yarn volume gradually decreases, after the spindle becomes larger in winding the chenille yarn, the resistance of pulling the core yarn and the wool yarn becomes smaller, so the main motor and the wool yarn can be lifted. The output speed of the motor increases the production capacity without causing the core yarn or the wool yarn to be broken and forced to stop.

Due to the increased output speed of the main motor and the wool yarn motor, the production of meters per minute can be achieved.

Preferably, the chenille production method of this embodiment uses the above-mentioned chenille machine.
