Method for producing yarn

A method of manufacturing a yarn that, in order to manufacture a yarn in which filler materials are loaded into a tubular member, comprises the steps:

• knitting a wire material to form the tubular member;
• guiding the filler materials that are formed into a strip-like shape, toward an opening of the tubular member;
• and,
• in order to load the filler materials into the tubular member, from a middle stage of formation of the tubular member, charging the filler materials guided to the opening into the tubular member through the opening in a state where longitudinal directions of the filler materials are made extending along an axial direction of the tubular member, wherein,
• 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, and,
• 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 an 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.
