본 발명은 전방향족 폴라아미드 필라멘트 등과 같은 광섬유 커버링용 필라멘 트 합사물의 권취 드럼에 관한 것으로서, 보다 구체적으로는 광케이블 제조를 위해 광섬유를 커버링할 때 합사된 필라멘트 일부가 장력 편차로 늘어져 쳐지는 현상을 효과적으로 방지할 수 있는 필라멘트 합사물의 권취 드럼에 관한 것이다.The present invention relates to a winding drum of a filament braided fiber for covering an optical fiber, such as a wholly aromatic polyamide filament, and more particularly, a phenomenon in which a part of the filament filament sags due to a tension deviation when the fiber is covered to manufacture an optical cable. The present invention relates to a winding drum of filament yarn which can be effectively prevented.
광케이블 제조시 필라멘트의 일종인 전방향족 폴리아미드 필라멘트는 여러가닥이 합사된 상태(이하 "필라멘트 합사 다발"이라고 한다)로 광섬유를 커버링(Covering)해 주는 보강재로 사용되고 있다.The whole aromatic polyamide filament, which is a kind of filament in the manufacture of optical cable, is used as a reinforcing material for covering an optical fiber in a state in which multiple strands are joined (hereinafter referred to as "filament filament bundle").
광섬유를 커버링할 때 표면적을 넓게하고 모듈러스를 향상시키기 위해서는 상기 필라멘트 합사 다발은 꼬임이 없는 무연 상태를 유지하는 것이 바람직하다.In order to increase the surface area and improve the modulus when covering the optical fiber, it is desirable that the filament filament bundle be kept free of twist.
통상적으로, 상기 필라멘트 합사 다발에 꼬임이 부여되면 모듈러스가 저하되고 광섬유를 커버링할 때 표면적이 좁아지는 문제가 발생된다.Typically, when the filament yarn bundle is provided with a twist, the modulus is lowered and the surface area is narrowed when covering the optical fiber.
상기와 같이 필라멘트 합사 다발 내에 꼬임이 없는 경우 광섬유를 커버링하는 등의 후공정을 위해 상기 필라멘트 합사 다발을 해사하는 경우 필라멘트 합사 다발을 구성하는 필라멘트 일부가 장력편차로 인해 늘어져 부분 부분 쳐지는 현상이 발생하는 문제가 빈번하게 발생된다.When there is no twist in the filament yarn bundle as described above, when dissolving the filament yarn bundle for a post process such as covering the optical fiber, a part of the filament constituting the filament yarn bundle is drooped due to the tension deviation, thereby causing a partial droop. The problem occurs frequently.
따라서, 필라멘트 여러가닥을 합사하여 필라멘트 합사 다발을 제조하는 공정에서는 각각의 필라멘트에 균일한 해사 장력을 부여하는 것이 매우 중요하다.Therefore, it is very important to give uniform filament tension to each filament in the process of filament filament bundle bundle by flocking multiple filaments.
종래 필라멘트의 합사시에는 필라멘트가 감겨져 있는 보빈(2)이 꽂혀져 있는 다수개의 크릴(Creel, 1)들로 이루어진 크릴부, 크릴부의 보빈(2)들로 부터 필라멘트들을 해사 시켜 합사하는 다수개의 드라이버 로울러(3a, 3b, 3c) 및 권취로울러(5)로 구성되는 합사장치가 주로 사용되어 왔으나, 보빈으로부터 해사되는 각각 의 필라멘트의 해사 장력을 효과적으로 조절해 주는 수단이 구비되지 않아 크릴에서 해사되는 필라멘트의 해사 장력을 일정하게 조절할 수 없는 문제점이 있었다.When filament of the conventional filament, a plurality of drivers to disassemble the filaments from the krill part consisting of a plurality of krill (Creel, 1) in which the filament wound bobbin (2) is plugged, and filaments from the bobbin of the krill part 2 A weaving device composed of rollers (3a, 3b, 3c) and winding rollers (5) has been mainly used, but filaments that are dissociated in krill because there is no means to effectively control the dissipation tension of each filament dissipated from bobbins There was a problem that can not adjust the maritime tension constant.
그로인해 종래 필라멘트의 합사방법으로 제조된 필라멘트 합사 다발을 후공정에서 해사시 장력편차로 인해 필라멘트 일부가 늘어져 아래로 쳐지는 현상이 발생되었다.As a result, a portion of the filament squeezed down due to the tension deviation during dismantling of the filament filament bundle manufactured by the filament weaving method according to the related art has occurred.
본 발명은 광케이블 제조를 위해 광섬유를 필라멘트 합사물로 커버링할 때 상기 합사물을 구성하는 필라멘트 일부가 장력 편차로 늘어져 쳐지는 현상을 효과적으로 방지할 수 있는 광섬유 커버링용 필라멘트 합사물의 권취 드럼을 제공하고자 한다.The present invention is to provide a winding drum of the filament yarn for fiber covering covering the fiber can be effectively prevented from sagging due to the tension variation when the fiber covering the optical fiber with the filament yarn for the manufacture of the optical cable .
이하, 본 발명을 상세하게 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.
본 발명에 따른 광섬유 커버링용 필라멘트 합사물의 권취 드럼은 도 2에 도시된 바와 같이 필라멘트들이 무연(無撚) 상태로 합사된 합사물이 권취되어 있는 광섬유 커버링용 권취 드럼에 있어서, 상기 권취 드럼의 상면(A) 및 하면(B) 중 어느 한면 이상에 호제가 부착되어 있는 것을 특징으로 한다.The winding drum of the filament yarn for fiber covering according to the present invention is an optical fiber covering winding drum in which the filaments are spun in a lead-free state as shown in FIG. 2, wherein the top surface of the winding drum It is characterized by the above-mentioned adhering to any one or more of (A) and lower surface (B).
도 2는 본 발명에 따른 권취 드럼의 사시 개략도이다.2 is a perspective schematic view of the winding drum according to the invention.
본 발명은 도 2와 같이 권취 드럼의 측면(C)에는 호제가 부착되어 있지 않 고, 그의 상면(A)과 하면(B) 중 어느 한면 이상에만 호제가 부착되어 있다.In the present invention, as shown in Fig. 2, no adhesive is attached to the side surface C of the winding drum, and the adhesive is attached only to at least one of the upper surface A and the lower surface B thereof.
그로인해, 광섬유 커버링을 위해 상기 권취 드럼으로부터 필라멘트 합사물을 해사시키면 상기 합사물의 길이 방향으로 일정 간격을 두고 상기 합사물에 호제가 부착되어 있는 상태가 된다.As a result, when the filament yarn is dismantled from the winding drum for fiber covering, the glue is attached to the yarn at regular intervals in the longitudinal direction of the yarn.
호제가 부착된 권취 드럼의 상면(A) 및/또는 하면(B)에 위치하는 합사물이 해사될 때에는 호제의 접착력에 의해 해사 장력이 미세하게 높아지면서 결국에는 해사 장력을 일정하게 조절하는 효과를 발현하게 된다.When the composite material located on the upper surface (A) and / or the lower surface (B) of the winding drum to which the agent is attached is dissolved, the sea tension is increased finely by the adhesion of the agent, and eventually the effect of adjusting the sea tension is constant. Expression.
그로인해, 해사되는 합사물의 해사 장력이 균일하게 조절되어 상기 합사물을 구성하는 필라멘트 일부가 장력 편차로 늘어져 쳐지는 현상을 효과적으로 방지하게 된다.
보다 구체적으로, 본 발명은 호제가 부착된 합사물 부분의 해사 장력이 미세하게 높아지기 때문에, 다시말해 해사장력이 일정주기로 순간 순간 미세하게 높아지기 때문에, 미세한 해사장력 편차로 인해 합사물내 필라멘트 일부가 늘어져 쳐지는 현상을 순간 순간 보정하게 되고, 그로 인해, 결국에는 해사장력이 일정하게 되는 효과가 발현된다.As a result, the sea tension of the spun yarn to be dissipated is uniformly adjusted, thereby effectively preventing the filament constituting the spliced sag from sagging due to tension variation.
More specifically, in the present invention, since the sea tension of the braided portion of the splinter is finely increased, that is, since the sea power is slightly increased momentarily at a constant cycle, the part of the filament in the yarn is stretched due to the slight variation in sea power. The drooping phenomenon is instantaneously corrected, and as a result, the effect of making the coastal force constant is expressed.
상기 호제는 폴리메틸메타아크릴레이트-부틸아크릴레이트 공중합물 등이다.The said favorable agent is a polymethylmethacrylate- butylacrylate copolymer, etc.
본 발명에 따른 권취 드럼은 상기 호제를 메틸알콜, 에틸알콜 등의 희석제에 용해시켜 호제액을 제조한 다음, 상기 호제액을 권취드럼의 상면(A)과 하면(B) 중 어느 한면 이상에 도포하는 방식 등으로 제조할 수 있다.The winding drum according to the present invention is prepared by dissolving the scavenger in a diluent such as methyl alcohol or ethyl alcohol, and then applying the scavenger solution to at least one of the upper surface (A) and the lower surface (B) of the winding drum. It can manufacture in a manner to make.
호제 부착율은 권취 드럼에 권취된 상기 합사물의 전체 중량대비 1~10중량%인 것이 바람직하다.It is preferable that the adhesive adhesion rate is 1 to 10% by weight relative to the total weight of the sieved material wound on the winding drum.
본 발명은 광케이블 제조를 위해 광섬유를 필라멘트 합사물로 커버링하는 공정 중에 합사된 필라멘트 일부가 장력 편차로 늘어져 쳐지는 현상을 효과적으로 방지할 수 있다.The present invention can effectively prevent a phenomenon that the filament part of the filament is sag down due to the tension deviation during the process of covering the optical fiber with the filament filament for the optical cable manufacturing.
