Abstract
In order to manufacture a yarn in which filler materials are loaded into a tubular member, the method of manufacturing a yarn has a step of knitting a wire material to form the tubular member. In the step of knitting the wire material, knitting of the wire material is advanced by a plurality of knitting needles, which are placed substantially concentrically about a rotation axis, while revolvingly moving the knitting needles about the rotation axis. When a stitch is to be formed by the wire material, the wire material is prepared so that an arcuate loop portion, which defines a part of the external shape of the stitch, is expanded in a direction which, in a state where the tubular member is developed, is inclined with respect to a straight line that extends in the axial direction of the tubular member.
