More particularly, the present invention relates to: a method for manufacturing water-repellent coated yarn which uniformly adheres a fluorine-free (C0) water-repellent coating agent to the surface of a workpiece to prevent damage to the water-repellent coating layer formed on the surface even when exposed to moisture for a long time to maintain stable water-repellent coating performance; and the water-repellent coated yarn manufactured by using the same.

본 발명은 발수 코팅사의 제조방법, 및 이를 이용하여 제조된 발수 코팅사에 관한 것으로, 더욱 상세하게는 피가공사의 표면에 무불소(C0) 발수 코팅제를 균일하게 고착하여서, 장시간 수분이나 노출되더라도 표면에 형성된 발수 코팅층의 손상을 방지하여 안정된 발수 코팅성능이 유지되도록 한 발수 코팅사의 제조방법, 및 이를 이용하여 제조된 발수 코팅사에 관한 것이다.The present invention relates to a method for manufacturing water-repellent coated yarn, and to a water-repellent coated yarn manufactured using the same. It relates to a method for producing a water-repellent coated yarn to prevent damage to a water-repellent coating layer formed on a surface so that stable water-repellent coating performance is maintained, and a water-repellent coated yarn manufactured using the same.

일반적으로, 삽입형 생리대(탐폰)의 경우에는 추후 질내에서 인출하기 위해 발수 코팅사로 이루어진 인출끈이 형성된다.In general, in the case of an insert-type sanitary napkin (tampon), a draw-out string made of water-repellent coated yarn is formed to be drawn out later in the vagina.

그리고, 상기 인출끈 등의 발수 코팅사는 장시간 수분에 노출된 상태를 유지함에 따라 수분에 의한 오염을 방지하기 위하여, 안정된 발수성능이 요구된다.In addition, stable water-repellent performance is required in order to prevent contamination by moisture as the water-repellent coating thread such as the draw-out string maintains a state exposed to moisture for a long time.

예컨대, 상기 인출끈의 발수성능이 떨어지면 인출끈 내에 수분들이 유입, 및 세균들이 다량 증식하므로, 안정된 위생상태를 담보하기 어렵게 된다.For example, if the water-repellent performance of the draw-out string is deteriorated, moisture flows into the draw-out string and a large amount of bacteria proliferates, making it difficult to ensure a stable sanitary condition.

그런데, 종래 상기 삽입형 생리대를 구성하는 인출끈 등을 구성하는 발수 코팅사의 제조방법은, 이송롤러를 통해 피가공사인 합연사를 길이방향으로 연속하여 이동하면서, 상기 합연사의 이동경로 상에 배치된 발수 코팅액에 합연사를 함침처리하고 이를 건조하여서, 합연사의 표면에 발수 코팅층이 형성하는 순으로 이루어진다.However, in the conventional manufacturing method of the water-repellent coated yarn constituting the draw-out string constituting the insert-type sanitary napkin, the ply-twisted yarn, which is a workpiece, is continuously moved in the longitudinal direction through a transfer roller, and the ply-twisted yarn is disposed on the moving path of the ply-twisted yarn. The ply-twisted yarn is impregnated with the water-repellent coating solution and dried to form a water-repellent coating layer on the surface of the ply-twisted yarn.

따라서, 종래 발수 코팅사의 제조방법에 의해 제조된 발수 코팅사는 요하는 발수 성능을 담보하기 어렵고, 생산성이 현저히 떨어지고 시설 투자비용이 높은 문제점이 지적되고 있다.Therefore, water-repellent coated yarns manufactured by conventional methods for producing water-repellent coated yarns are difficult to secure required water-repellent performance, productivity is significantly lowered, and facility investment costs are high.

특히, 종래에는 복수의 원사가 합연된 합연사를 발수 코팅하므로 합연사를 구성하는 원사 조직 내에 발수 코팅액이 균일하게 침투하기 어려울 뿐더러, 발수 코팅사를 구성하는 합연사의 안정적인 세척이 어려워 이를 통해 제조된 발수 코팅사는 이물질의 잔류에 의해 안정적인 위생을 담보하기 어렵다.In particular, in the prior art, since the ply-twisted yarn in which a plurality of yarns are plied is water-repellently coated, it is difficult for the water-repellent coating liquid to uniformly penetrate into the yarn structure constituting the plied-twisted yarn, and it is difficult to stably wash the ply-twisted yarn constituting the water-repellent coated yarn. It is difficult to ensure stable hygiene due to residual foreign substances in the water-repellent coated yarn.

Water-repellent coating is used to mass-produce water-repellent coated yarns that prevent contamination by water even when exposed to water by being inserted into the human body for a long time due to stable water-repellent performance. let's elaborate

[피가공사 권취공정][Workpiece Winding Process]

본 공정에서는 도 1과 도 2와 같이 복수의 분출공들이 내외측으로 관통하여 형성된 중공의 타공보빈(10)에, 발수 코팅을 요하는 피가공사(Y)를 권취한다.In this process, as shown in FIGS. 1 and 2, the workpiece Y requiring water-repellent coating is wound around the hollow perforated bobbin 10 formed by passing through the inside and outside of the plurality of ejection holes.

상기 타공보빈(10)에 권취되는 피가공사(Y)로는, 방사된 원사, 또는 복수의 원사들을 합연한 합연사 등이 채택될 수 있다.As the to-be-processed yarn (Y) wound around the perforated bobbin 10, a spun yarn or a plied yarn obtained by plying a plurality of yarns may be adopted.

본 실시예에서는 원사를 피가공사(Y)로 채택하여 후술되는 일련의 발수 코팅과정을 마친 다음, 후가공을 통해 이들 원사를 합연기에 투입 및 합연하여 요하는 굵기와 강도를 갖는 발수 코팅사를 형성하도록 한다.In this embodiment, yarn is adopted as the workpiece (Y) to complete a series of water-repellent coating processes described below, and then, through post-processing, these yarns are put into a plying machine and plied to obtain a water-repellent coated yarn having a required thickness and strength. to form

그리고, 상기 중공의 타공보빈(10)의 외경면에 피가공사(Y)를 팽팽히 당김하여 권취하지 아니하고 느슨하게 소프트(SOFT) 형태로 권취하여서, 후술되는 바와 같이 권취된 피가공사(Y) 사이로 분출공(12)들을 통해 분출되는 물이나 발수 코팅액이 안정되게 투과하면서 권취된 피가공사(Y) 내에 잔류된 이물질의 안정적인 세정과, 피가공사 조직 내에 발수 코팅액의 안정된 침투가 가능하도록 한다.Then, the workpiece (Y) is not pulled tight and wound on the outer diameter surface of the hollow perforated bobbin 10, but is loosely wound in a soft form, and as will be described later, between the wound workpieces (Y) Stable penetration of the water or water-repellent coating liquid ejected through the spout holes 12 enables stable cleaning of foreign substances remaining in the wound workpiece Y and stable penetration of the water-repellent coating solution into the tissue of the workpiece.

필요에 따라서는, 도 2b와 같이 상기 발수 코팅을 요하는 원사나 합연사 등의 피가공사(Y) 보다 상대적으로 조직 밀도가 낮은 발수재질의 투수사(Y')를 피가공사(Y)와 함께 타공보빈(10)의 외경에 소프트형태로 권취하여서, 상기 투수사(Y')에 의해 피가공사(Y) 사이의 투수효율을 증대되도록 하는 것이 바람직하다.If necessary, as shown in FIG. 2B, a water-permeable yarn (Y') made of a water-repellent material having a relatively lower tissue density than the processed yarn (Y) such as yarn or ply-twisted yarn requiring the water-repellent coating is used as the processed yarn (Y). It is preferable to increase the water permeability between the to-be-processed yarns (Y) by the water-permeable yarns (Y') by winding them in a soft form on the outer diameter of the perforated bobbin (10).

본 실시예에 따른 타공보빈(10)은 외벽에 복수의 분출공(12)들이 형성된 타공관체로 구성되고, 상기 타공보빈(10)의 외경면에 권취된 피가공사(Y)는 분출공(12)들을 통해 타공보빈(10)의 중공부(11)와 연통하도록 한다.The perforated bobbin 10 according to the present embodiment is composed of a perforated pipe body having a plurality of ejection holes 12 formed on the outer wall, and the workpiece Y wound around the outer diameter surface of the perforated bobbin 10 is ejected through the ejection hole ( 12) to communicate with the hollow part 11 of the perforated bobbin 10.

그리고, 상기 타공보빈(10)은 경량성과 우수한 내열성과 열전도성을 갖는 알루미늄 재질로 제작되어 후술되는 열간 고착공정에서도 안정된 형태 안정성을 유지하고, 또 간접 가열을 통해 권취된 피가공사에 열기를 안정되게 발산하여 권취된 피가공사의 신속하고 균일한 건조를 도모한다.In addition, the perforated bobbin 10 is made of aluminum material having light weight, excellent heat resistance and thermal conductivity, and maintains stable shape stability even in the hot fixing process described later, and also stabilizes the heat to the workpiece wound through indirect heating. It promotes rapid and uniform drying of the wound workpiece by diverging to a high level.

또한, 본 실시예에서는 상기 타공보빈(10)의 중공부(11) 내에는 입구에서 출구로 갈수록 점차 직경이 증가하는 상광하협한 형상의 확산코어(13)를 동심구조로 배치한다.In addition, in the present embodiment, a diffusion core 13 having a narrow upper and lower shape, the diameter of which gradually increases from the inlet to the outlet, is disposed in the hollow part 11 of the perforated bobbin 10 in a concentric structure.

따라서, 후술되는 바와 같이 타공보빈(10)의 중공부(11)에 급수되는 물이나, 발수 코팅액은 중공부(11)를 통과하면서 확산코어(13)에 의해 분출공(12)들이 형성된 외측으로 확산하여서, 외벽에 형성된 분출공(12)을 통해 피가공사(Y)가 권취된 외경면으로 고압 분출된다.Therefore, as will be described later, water supplied to the hollow part 11 of the perforated bobbin 10 or the water-repellent coating liquid passes through the hollow part 11 to the outside where the ejection holes 12 are formed by the diffusion core 13. It diffuses and is blown out at high pressure through the blowout hole 12 formed in the outer wall to the outer diameter surface around which the workpiece Y is wound.

이때, 상기 중공부(11)의 입구를 통해 급수된 물이나 발수 코팅액은 확산코어(13)에 형성된 경사면을 통해 외측으로 서서히 확산되고, 결과적으로 타공보빈(10)에 형성된 분출공(12)들에는 균일한 압력으로 급수된 물이나 발수 코팅액이 분출된다.At this time, the water supplied through the inlet of the hollow part 11 or the water-repellent coating liquid is gradually diffused outward through the inclined surface formed in the diffusion core 13, and as a result, the ejection holes 12 formed in the perforated bobbin 10 Water or water-repellent coating liquid is ejected at a uniform pressure.

즉, 상기 타공보빈(10)의 중공부(11)는 원뿔대, 또는 원추형의 확산코어(13)에 의해 순환 펌프부(30)의 급수단(31)과 연결된 입구에서 출구로 갈수록 유로가 좁혀지므로, 상기 타공보빈(10)에 형성된 분출공(12)들을 통해 물이나 발수 코팅액은 균일하게 분출된다.That is, the flow path of the hollow part 11 of the perforated bobbin 10 is narrowed from the inlet connected to the supply means 31 of the circulation pump part 30 to the outlet by the truncated conical or conical diffusion core 13. , Water or water-repellent coating liquid is uniformly ejected through the ejection holes 12 formed in the perforated bobbin 10.
