Referring to fig. 1 to 11, in a method for manufacturing an elastic yarn, the elastic yarn 61 manufactured by the method comprises a yarn core 16 and an outer sleeve layer 1 wrapped on the yarn core. The yarn core comprises an inner core 2 and an outer sheath 3 wrapped around the inner core. The inner core is cotton structure, and the inner core has the stranded. The hardness of the outer sheath is greater than that of the inner core, and the outer sheath is of a waterproof structure. The outer sheath is provided with a plurality of outer sheath water seepage holes 4 which are through holes penetrating through the inner and outer circumferential surfaces of the outer sheath, the outer sleeve is provided with outer sleeve part bulges 5 filling the outer sheath water seepage holes, and the outer sleeve part bulges and the outer sleeve layer are integrally formed together. The elastic yarn also comprises a plurality of elastic yarn part air holes 6 which penetrate through the outer sleeve layer and the outer sheath. All the elastic yarn part air holes are positioned on the same side of the plane passing through the center line of the elastic yarn. The plane of the central line passing through the elastic yarn is in a horizontal state, and when the air holes of the elastic yarn part are positioned at the lower side of the plane of the central line passing through the elastic yarn, the air holes of the elastic yarn part are inclined holes with the outer ends facing downwards.
The method comprises the specific steps of firstly, making a yarn core, wherein the yarn core comprises an inner core and an outer sheath wrapped outside the inner core, the inner core is of a cotton structure, the hardness of the outer sheath is greater than that of the inner core, the outer sheath is of a waterproof structure, a plurality of outer sheath part water seepage holes are formed in the outer sheath, the outer sheath part water seepage holes are through holes penetrating through the inner peripheral surface and the outer peripheral surface of the outer sheath, an outer sheath layer part bulge filling the outer sheath part water seepage holes is formed in the outer sheath layer, and the outer sheath part bulge and the outer sheath layer are integrally formed; and step two, wrapping the outer sleeve layer on the yarn core: and water enters the outer sheath from the water seepage holes of the outer sheath part to enable the outer sheath to be in a filling state, the yarn core in the filling state is pulled out in a suspended state from an opening of a yarn outlet nozzle of the drawing machine, the material for manufacturing the outer sleeve layer in a molten state is extruded from the opening of the yarn outlet nozzle, and the material for manufacturing the outer sleeve layer is solidified after wrapping the inner core to form the outer sleeve layer. Specifically, the method is completed by, but not limited to, an elastic yarn production apparatus including a screw feeder 7, a coloring device 8, a traction box 9, and a drying device 10, which are sequentially provided from left to right. The screw feeder is provided with a feed inlet 11 and a wire outlet 12. The screw feeder also includes a steeping barrel 13 and an inner core output nozzle 14. A guide wheel 15 is also arranged between the soaking barrel and the inner core output nozzle.
