Abstract
A device for manufacturing a double-sided yarn for artificial turf, includes: a 1-liquid supply pipe through which a molten 1-liquid is supplied; a 2-liquid supply pipe which is disposed in a space physically separated from the 1-liquid supply pipe and through which a molten 2-liquid is supplied; and a confluence unit in which the 1-liquid introduced through the 1-liquid supply pipe and the 2-liquid introduced through the 2-liquid supply pipe join.

1-6. (canceled)
A double-sided yarn for artificial turf to include a first surface and a second surface including any one of the following:
- (1) the first surface and the second surface have different colors;
- (2) the first surface and the second surface have different glosses;
- (3) the first surface and the second surface have different roughnesses;
- (4) the first surface and the second surface have different warpages depending on changes in the intensity, wavelength, or temperature of irradiated light;
- and
- (5) combinations of (1) to (4) above;
- wherein the first surface and the second surface formed by the 1-liquid and the 2-liquid each of which is supplied by a device for manufacturing a double-sided yarn for artificial turf,
- wherein the device for manufacturing a double-sided yarn for artificial turf, comprising:
- a 1-liquid supply pipe through which a molten 1-liquid is supplied;
- a 2-liquid supply pipe which is disposed in a space physically separated from the 1-liquid supply pipe and through which a molten 2-liquid is supplied;
- a confluence unit in which the 1-liquid introduced through the 1-liquid supply pipe and the 2-liquid introduced through the 2-liquid supply pipe join;
- a slit mold unit which is disposed below the confluence unit;
- a 2-liquid separation discharge pipe for separating and discharging the 2-liquid into the plurality of the confluence units before the 2-liquid supplied through the 2-liquid supply pipe flow into the confluence units;
- a 2-liquid confluence pipe extended to a predetermined length so that the 2-liquid separated through the 2-liquid separation discharge pipe can flow in a horizontal direction;
- and a 1-liquid chamber which is formed above the confluence unit and provided with a 1-liquid chamber passing pipe through which the 1-liquid passes,
- the 1-liquid and 2-liquid flow into the slit mold unit while they are continuously flowing, and the double-sided yarn is formed in a form in which the 1-liquid and 2-liquid contact each other within the slit mold unit,
- the 2-liquid confluence pipe extends from the lower portion of the 1-liquid chamber and the end of the 2-liquid confluence pipe is connected to the confluence unit,
- the confluence unit have a structure extending from the distal end of the 1-liquid chamber passing pipe in a direction away from the 2-liquid confluence pipe by which the 1-liquid, which has flowed into the confluence unit, is pushed a predetermined distance by the hydraulic pressure of the 2-liquid introduced along the 2-liquid confluence pipe, and accordingly, the 1-liquid and 2-liquid may be stably introduced into the slit mold unit by offsetting the hydraulic pressure and flow rate differences between the 1-liquid and 2-liquid above the slit mold unit,
- the double-sided yarn having a denier of 150 to 2500 denier based on the monofilament.
