Method for recycling false selvedges of rapier loom

The invention provides a method for recycling false selvedges of a rapier loom, wherein annular false selvedges and a yarn separation box are arranged on the rapier loom; the silk separation box is arranged in the middles of the annular false selvedges; waste yarns are introduced into the silk separation box by weaving the annular false selvedges with the waste yarns; after the waste yarns are removed from the annular false selvedges by the silk separation box, the annular false selvedges are introduced into a false selvedge circulating channel of the rapier loom again to realize the recycling of the false selvedges; the silk separation box is internally provided with a silk separation plate and a draught fan; one side of the silk separation box is provided with an annular false selvedge inlet while the other side is provided with an annular false selvedge outlet; the annular false selvedge inlet and the annular false selvedge outlet are parallel to each other; the inner side of the annular false selvedge outlet is provided with the draught fan while the outer side of the annular false selvedge outlet is connected with the annular false selvedge circulating channel; silk separation holes for spacing the annular false selvedge are formed on the silk separation plate from top down; five annular false selvedges penetrate through the silk separation holes respectively; and the bottom of the silk separation plate is provided with a waste yarn collecting box.
