A yarn carrier is provided of the type including a substantially rigid tubular core having passageways through the sidewall thereof for the passage of dye or wet finishing bath into the yarn to be wrapped thereon. A filter sleeve is wrapped around the outer surface of the tubular core to prevent entrapment of the yarn in the passageways and for filtering the dye and/or finishing bath. The filter sleeve is formed from a filter material which is wrapped into a sleeve and abutting edges of the filter material are bonded together along a seam. The seam is contemplated to be substantially continuous and extend the length of the sleeve. The tubular sleeve is slid over or heat shrunk onto the outside surface of the tubular core prior to the winding of the yarn thereon.
