보다 상세하게는, More specifically,

상기 혼합단계(S1)에서는 PE(polyethylene)원료 및 칼라염료가 중량비 100 : 4~5의 비율로 혼합되며In the mixing step (S1) is a PE (polyethylene) raw material and color dye is mixed in a ratio of weight ratio 100: 4 ~ 5

상기 제조단계(S2)는 도 1에 도시된 것과 같이, 제1,2 중공이 있는 제1,2사가 일체로 형성되어 있는 중공사가 제조되며 상기 제1,2중공 또는 브릿지중공을 구비한 중공사는 내포된 수분 혹은 습기의 표면장력을 극대화하여 수분 내포율을 향상시켰다.The manufacturing step (S2) is, as shown in Figure 1, the first and second hollow yarns having a hollow yarn is formed integrally formed, the hollow yarn having the first, second hollow or bridge hollow The moisture content is improved by maximizing the surface tension of contained moisture or moisture.

상기 제1냉각단계(S3)는 상기 제조단계에서 제조된 중공사를 섭씨20~25도의 용수에 투입하여 서서히 냉각시키며 1분당 10g~15g의 중공사를 냉각시키게 된다. 급속냉각하는 경우, PE의 결정이 급수축하여, 분자간 결속력이 저하되므로, 하단의 표와 같이 실온 25도에서 분당 10~15g의 중공사를 냉각시켜 중공사를 제조하는 것이 바람직하다.In the first cooling step S3, the hollow fiber prepared in the manufacturing step is slowly added to the water at 20 to 25 degrees Celsius, thereby cooling the hollow fiber of 10 g to 15 g per minute. In the case of rapid cooling, since the crystals of PE are water-shrinked and the intermolecular binding force is lowered, it is preferable to cool the hollow fiber at 10 to 15 g per minute at room temperature 25 degrees as shown in the table below to produce the hollow fiber.

상기 연신단계(S4)는 상기 제 1냉각단계를 통해 냉각된 중공사를 1 : 3.8~4.2의 비율로 용수안에서 연신하여 잔디사를 제조하는 것으로써, 연신율이 3.8~4.2 인 경우, 벽면의 효과적이며 균일한 경화를 도모하여, 내구성이 최적화되었으며, 연신율이 3.8미만인 경우 벽면의 두께로 인하여, 불균일하게 부분적으로 경화됨으로써, 내구성이 상대적으로 저하되었으며, 연신율이 4.2배를 초과하면 벽면의 효과적인 경화를 도모할 수 있으나 벽면의 두께가 현저하게 얇아져 절사될 수 있다는 문제점이 있다. The stretching step (S4) is to draw the hollow fiber cooled through the first cooling step in the water at a ratio of 1: 3.8 to 4.2 to produce a grass yarn, when the elongation is 3.8 to 4.2, the effective wall surface And uniform curing, durability is optimized, and when the elongation is less than 3.8, due to the thickness of the wall, due to the non-uniformly partially cured, the durability is relatively reduced, when the elongation exceeds 4.2 times effective curing of the wall surface Although it can be planned, there is a problem that the thickness of the wall surface can be significantly thinner and cut off.

상기 고착냉각단계(S5)는 연신되어 제조된 잔디사를 섭씨85~100도의 용수에서 1분에 10~15g의 잔디사를 서서히 냉각하여 중공잔디사를 제작한다.The fixing cooling step (S5) is to prepare a hollow grass yarn by slowly cooling the grass yarn of 10 to 15g per minute in the water of 85 ~ 100 degrees Celsius to stretch the produced grass yarn.

By using the injection-mixed mixture, the hollow fiber constituted by the 1st yarn in which the 1st hollow is formed, and the 2nd hollow in which the 1st hollow is formed and integrally molded with the 1st yarn can be manufactured. The hollow fiber is slowly cooled after it is introduced into the water at 20 to 25 degrees Celsius in the first cooling step, followed by stretching at 3.8 to 4.2 times the elongation in the water and cooling at 85 to 100 degrees Celsius, thereby manufacturing hollow grass yarn. .
