摘要： An object of the present invention is to efficiently apply oil to filaments in a structure in which the filaments are spun out downward from a single spinneret, divided into two groups, and bundled as two yarns.
A yarn production system 1 includes (i) a spinning apparatus 2 including a spinneret 24 provided with discharge ports 26, (ii) a cooler 4 provided below the spinneret 24, and (iii) an oiling unit 5 provided below the cooler 4. A virtual partitioning plane X divides the discharge ports 26 into a first discharge port group 26A and a second discharge port group 26B. The first discharge port group is arranged so that (i) discharge ports belonging to the first discharge port group form at least one first line extending in the front-rear direction (predetermined width direction) and at least one second line extending in a direction intersecting with the front-rear direction, (ii) one of the at least one first line has more discharge ports than the at least one first line, (iii) one of the at least one second line has more discharge ports than the at least one second line, and (iv) the one of the at least one first line is larger than the one of the at least one second line in terms of the number of the discharge ports, and the second discharge port group is arranged so that (i) discharge ports belonging to the second discharge port group form at least one first line extending in the front-rear direction (predetermined width direction) and at least one second line extending in the direction intersecting with the front-rear direction, (ii) one of the at least one first line has more discharge ports than the at least one first line, (iii) one of the at least one second line has more discharge ports than the at least one second line, and (iv) the one of the at least one first line is larger than the one of the at least one second line in terms of the number of the discharge ports. The oiling unit 5 includes a first oil supply surface 52a and a second oil supply surface 52b. When viewed in the up-down direction, an angle between a first width direction D1 and the virtual partitioning plane X is within the range of 45 to -45 degrees. When viewed in the up-down direction, an angle between a second width direction D2 and the virtual partitioning plane X is within the range of 45 to -45 degrees.
