Description

통신용 광케이블 방수용 흡수성 합연사 및 그 제조방법{Water Swelling Yarn Spinning Process and Machines for Water Blocked Optical Fiber Communications Cable}Water absorbing yarn for manufacturing waterproof optical fiber and its manufacturing method {Water Swelling Yarn Spinning Process and Machines for Water Blocked Optical Fiber Communications Cable}

본 발명은 통신용 광케이블의 방수를 목적으로 케이블의 외주면에 감아 사용되는 흡수성 합연사 및 그 제조방법에 관한 것이다.The present invention relates to an absorbent conjugated twisted yarn that is wound around an outer circumferential surface of a cable for the purpose of waterproofing an optical fiber for communication, and a method of manufacturing the same.

일반적으로 통신용 광케이블은 그 용도에 따라 다양한 종류가 있는데, 옥외에 설치되는 케이블과 옥내에 설치되는 광케이블 및 옥내와 옥외 사이에 설치되는 인입용 케이블로 크게 나뉘어 진다.In general, there are various types of communication optical cables according to the purpose, it is largely divided into a cable installed outdoors, an optical cable installed indoors, and a cable for entering between indoors and outdoors.

이와 같은 광케이블 중 옥외용 광케이블은 지상 또는 지하 또는 해저에 수십킬로미터에서 수천 킬로미터에 걸쳐 설치되는데, 장거리에 걸쳐 광케이블을 설치하는 경우 연결포인트가 발생하기 마련이다.Among such optical cables, outdoor optical cables are installed on the ground, underground or the sea floor for several tens of thousands to thousands of kilometers. If the optical cables are installed over long distances, connection points will occur.

그리고 설치되는 광케이블은 빗물 지하수 또는 해수에 광케이블이 노출됨을 방지하기 위하여 일반적으로 광케이블을 자켓(JACKET)에 수납하여 설치한다And in order to prevent the optical cable from being exposed to rainwater groundwater or seawater, the optical cable is generally installed by storing the optical cable in a jacket.

그런데 이와 광케블 자켓은 그 방수효과가 완전하지 못하고 특히 그 재질의 특성에 기인한 산화작용으로 인하거나 작업중 크랙이 발생되어 누수가 일어나는 경우가 발생하기도 한다.However, the optical cable jacket is not completely waterproof, and in particular, it may be caused by oxidation due to the characteristics of the material or by cracking during operation.

그리고 광케이블을 수백킬로미터 이상 장거리에 걸쳐 설치하는 경우 상기의 광케이블과 광케이블을 연결하는 연결포인트에서 자켓을 벗겨내고 광케이블을 연결하게 되는데 이 연결포인트에서 물에 노출될 우려가 크다.And when the optical cable is installed over a long distance of more than hundreds of kilometers, the jacket is removed from the connection point connecting the optical cable and the optical cable and the optical cable is connected, which is likely to be exposed to water at this connection point.

따라서 광케이블을 자켓에 수납하여 제작함에 있어서, 광케이블의 외주면에방수용 젤리를 도포하여 제작한다.Therefore, in storing and manufacturing the optical cable in the jacket, it is produced by applying a waterproof jelly to the outer peripheral surface of the optical cable.

그런데 이와 같이 방수용 젤리를 도포한 종래의 광케이블의 연결작업시 도포된 젤리를 벗겨내야 하는데 젤리를 벗기는 작업이 상당히 까다로우며 특히 작업자의 손이나 기타 작업공구등에 젤 리가 묻어 불편하며, 특히 젤리의 특성상 약간의 외력에 의하여도 도포된 젤리가 벗겨지므로 광케이블에 물이 누설될 염려가 상존하고 있다.However, when connecting the conventional optical cable coated with waterproof jelly, it is necessary to peel off the coated jelly, which is very difficult to remove, especially the worker's hand or other work tools, which is inconvenient due to the jelly. Since the applied jelly is peeled off even by a slight external force, there is a risk of water leakage on the optical cable.

이와 같은 문제점을 해결하기위하여 광케이블의 외주면에 젤리를 도포하는대신 아라미드 얀(ARAMID YARN), 글래스 얀(GLASS YARN)등 흡수성 방적사를 와인딩한다.To solve this problem, instead of applying jelly to the outer circumferential surface of the optical cable, an absorbent yarn such as ARAMID YARN and GLASS YARN is wound.

이들 방적사는 방수기능을 하는 방적사인데, 이 광케이블 방수용 흡수성 방적사는 수분에 노출되면 수분을 빨아들여 팽윤되는 섬유상의 고흡수성 폴리머로된 실을 포함하여 방적된 흡수성 방적사이다.These spun yarns are waterproof yarns that absorb water, and are absorbed spun yarns including yarns made of fibrous superabsorbent polymers that absorb and swell when exposed to moisture.

그런데 이와 같은 종래의 고흡수성 방적사는 별도로 고흡수성재 실을 제조하여 기타 천연섬유나 화학섬유재 실과 함께 방적을 해야 하기에 그 편리성에 불구하고 그만큼 제조과정이 복잡하였고 이에 따라 제조원가가 높은 단점이 있다.However, such a conventional super absorbent yarn has to manufacture a super absorbent yarn separately and spun together with other natural fibers or chemical fiber yarns, so that the manufacturing process is complicated in spite of its convenience and the manufacturing cost is high. .

상기와 같은 종래의 광케이블 방수용 흡수성 방적사의 문제점을 해결하기 위하여 본 발명이 창안된 것인데, 본 발명의 목적은 보다 간편한 방법으로 방수기능을 갖는 광케이블 방수용 흡수성 합연사를 제공하고자, 보통의 실에 고 흡수성 수지분말을 점착제와 함께 도포하고, 고흡수성폴리머가 도포된 여러가닥의 실을 꼬아 연사한 광케이블 방수용 합연사 및 그 제조방법을 제공하는데 그 특징이 있다.The present invention was devised to solve the problems of the conventional optical fiber waterproof absorbent yarn as described above, the object of the present invention is to provide an absorbent twisted yarn for waterproof optical fiber having a waterproof function in a more convenient way, high absorbency in ordinary yarn The resin powder is applied together with the pressure-sensitive adhesive and twisted and twisted several strands of the superabsorbent polymer coated thereon to provide an optical fiber waterproofing twisted yarn and its manufacturing method.

상기 합사공정(1)은 상술한 바와 같이 합사장치(100)에 의하여 여러가닥의 실을 일렬배열하게 하여 권취용 보빈(130)에 권취시키는 공정인데, 상기 합사장치(100)는 도 2에 도시된 바와 같이 자연섬유사 또는 화학섬유사가 개별적으로 한줄씩 감겨있는 다수개의 실패(110)와 이들 여러가닥의 실을 일렬로 상호 인접하여 배열하여 합사하느 합사용슬릿구(120), 합사에 장력을 부여하는 텐션구(130), 그리고 텐션구(130)를 거쳐 일렬로 배열하여 합쳐진 합사를 권취하는 권취용 보빈(140)으로 구성된다. 상기 합사용슬릿구(120)은 가늘고 긴 슬릿구가 형된 것으로 이슬릿구에 여러개의 실패(110)에서 풀려나온 여러가닥의 실을 서로 인접하여 일렬로 배열되게 하는 것이며, 상기 텐션구(130)는 한자 가로 왈자 즉 曰자 형태로 형성되어 가운데에 형성된 좁은 슬릿형태의 두 구멍을 지그재그로 여러가닥의 실이 지나가게 하여 합사된 실자체에 탠션을 부여하는 것이다.The envoying step (1) is a process of winding the bobbin 130 for winding by arranging a plurality of threads in a row by the envoy device 100 as described above, the envoy device 100 is shown in FIG. As shown, the natural fiber yarn or the chemical fiber yarn is wound several times (110) and the yarn of the joint thread slit (120), which is arranged to be adjacent to each other in a row arranged in a row adjacent to each other in a row It is comprised by the tensioning part 130 to give, and the winding bobbin 140 which winds up the cohesive yarn which was arrange | positioned in a line through the tensioning part 130, and joined. The slit ball 120 is a long slits are formed in the slitting sphere is to be arranged in a row adjacent to each other the strands of several strands released from the failure 110 in the slit sphere, the tension sphere 130 It is a zigzag two holes of narrow slit shape formed in the shape of Chinese character, that is, zigzag, and zigzag to pass several threads to give tension to the threaded yarn itself.

상기 접착제도포공정(2)은 접착제도포장치(200)에 의하여 합사에 접착제를 도포하는 공정인데, 도 3에 도시된 바와 같이 접착제도포장치(200)는 두 개의 접착제용기(220)과 스폰지(210)으로 구성된다.The adhesive coating process (2) is a process of applying the adhesive to the plywood by the adhesive coating device 200, as shown in Figure 3, the adhesive coating device 200 is two adhesive containers 220 and sponge 210 It is composed of

상기 접착제용기(220)에는 수용성 접착제(A)가 수용되어 있는데, 두 접착제용기(220)는 약간의 사이공간을 두고 인접하여 설치된다.The adhesive container 220 is accommodated in the water-soluble adhesive (A), the two adhesive containers 220 are installed adjacent to each other with a little space.

상기 스폰지(210)는 "∩" 형태의 형상을 취하여 양 다리부분이 두 접착제용기(220)에 각각 뻗어 수용되어 수용성 접착제와 접하게 되어 있어 스픈지(210)는 수용성접착제를 빨아들여 함유하게 된다.The sponge 210 has a shape of “∩”, and both legs are respectively extended to be accommodated in the two adhesive containers 220 to be in contact with the water-soluble adhesive, so that the sponge 210 contains the water-soluble adhesive.

그리고 스폰지(210)의 상부 중앙을 관통하여 양 다리사이로 합사가 통과되는 슬릿(211)이 형성되어 있다.A slit 211 is formed through the upper center of the sponge 210 and the slit through both legs.

따라서 합사가 스폰지(210)의 슬릿(211)을 통과하면 스폰지(210)에 함유된 수용성접착제(A)가 합사에 도포하게 된다.Therefore, when the plywood passes through the slit 211 of the sponge 210, the water-soluble adhesive (A) contained in the sponge 210 is applied to the plywood.

아와 같이 합사가 스폰지(210)의 슬릿(211)을 통과함에 있어 통과속도는 합사를 구성하는 실의 굵기에 의존하는데 대략 6m/min∼10m/min의 속도로 한다.As mentioned above, the passing speed in the slit 211 of the sponge 210 depends on the thickness of the yarn constituting the plied yarn, and the speed is approximately 6 m / min to 10 m / min .

상기 고흡수성 폴리머분말 코팅공정(3)은 분말코팅기(300)에 의하여 고흡수성 폴리머 분말을 접착제가 도포된 합사에 코팅하는 것인데, 상기 분말코팅기(300)는 도 4에 도시된 바와 같이 내부에 고흡수성 폴리머 분말이 수용된 분말용기통(310)와 분말통 내부에 설치된 합사를 가이딩하는 두 개의 가이딩 휠(320, 320')로 구성된다.The superabsorbent polymer powder coating process (3) is to coat the superabsorbent polymer powder by the powder coating machine 300 to the adhesive coated yarn, the powder coater 300 is shown inside the high It consists of a powder container (310) containing the absorbent polymer powder and two guiding wheels (320, 320 ') for guiding the plywood installed inside the powder container.

상기 분말용기통(310)은 전면(全面)이 밀봉되어 있고 그 상부면에 일정 간격을 갖고 두 개의 슬릿(311, 311')이 형성된다. 두 슬릿 중 하나는 수용성 접착제가도포된 합사가 인입하는 인입용 슬릿(311)이고 다른 하나는 분말용기통(310)내에서 분말이 코팅된 합사가 인출되는 인출용 슬릿(311')이다.The powder container 310 is sealed in its entirety and two slits 311 and 311 'are formed at regular intervals on the upper surface thereof. One of the two slits is an inlet slit 311 into which the pliers coated with a water-soluble adhesive are drawn in, and the other one is a slit for pulling out 311 ′ from which the pulverized powder is drawn out in the powder container 310.

이와 같은 구성으로 이루어진 분말코팅기(300)는 상기 접착제도포장치(200)에서 접착제가 도포되어 이송되어온 합사를 분말용기통(300)의 인입용슬릿(311)으로 인입시켜 두 개의 가이딩 휠(320, 320')을 거쳐 인출용 슬릿(311')을 빠져나가는데, 분말용기통내(310)내에 수용된 고흡수성 폴리머 분말(P)이 인입된 합사에 접착제의 기능에 의하여 코팅되는 것이다.The powder coating machine 300 having such a configuration introduces the entrained yarn, which has been applied and transported by the adhesive coating device 200, into the inlet slit 311 of the powder container 300, thereby providing two guiding wheels 320. It exits the withdrawal slit (311 ') through, 320'), the superabsorbent polymer powder (P) accommodated in the powder container 310 is coated by the function of the adhesive on the inlet yarn.

본 발명에서 사용되는 고흡수성 폴리머 분말은 폴리비닐 알콜(Polyvinyl Alcohol), 폴리하이드록씨에틸메타크릴릭 산(Polyhydroxyethylmethacrylic Acid), 폴리에틸렌 글리콜(Polyethylene Glycol) 등을 가교시킨 폴리머로써,The superabsorbent polymer powder used in the present invention is a polymer crosslinked with polyvinyl alcohol, polyhydroxyethylmethacrylic acid, polyethylene glycol, and the like.

흡수력(吸水力)이 매우 큰 물질로 된 분말체이다.It is a powder made of a substance with very high absorption.

고흡수성 폴리머은 매우 뛰어난 흡수성을 갖는 것으로 가교밀도가 높아질수록 수지의 성질이 수용성에서 팽윤성을 갖는데 흡수가 된 후 압력을 가해도 물이 빠져나오지 않는 경이적인 특징을 갖는 물질이다. 본 발명에서 사용되는 고흡수성 폴리머는 50메쉬(mesh)이상의 분말상의 스타크(Starch)계 폴리머 또는 합성수지계 폴리머가 바람직하다. 이들 스타크계 또는 합성수지계 폴리머는 자체중량의 100배이상의 물을 흡수하는 흡수력을 갖는다.The superabsorbent polymer has a very excellent absorbency. As the crosslinking density increases, the resin has a swelling property in water solubility, but it is a material having a phenomenal characteristic that water does not escape even after being absorbed by pressure. The superabsorbent polymer used in the present invention is preferably a powdery Starch polymer or a synthetic resin polymer of 50 mesh or more. These stark-based or synthetic resin-based polymers have an absorbency of absorbing water at least 100 times its own weight.

상기 연사공정(4)은 상기 고흡수성 폴리머분말 코팅공정(3)을 통하여 고흡수성 폴리머분말(P)이 코팅된 합사(T)를 트위스팅기(도시 생략)에 의하여 도 5 에 도시된 바와 같이 일렬로 배열된 합사를 꼬아 합연사(T')로 만드는 공정인데, 합연사의 꼬임은 실의 굵기에 따라 연사의 1m당 30∼100개가 형성되도록 한다.The twisting step (4) is as shown in Figure 5 by a twisting machine (not shown) by the twisted yarn (T) coated with the super absorbent polymer powder (P) through the super absorbent polymer powder coating process (3) The twisted yarns are arranged in a twisted yarn (T ') process. The twisted twisted yarn is formed so that 30 to 100 per 1m of twisted yarn is formed depending on the thickness of the yarn.

상기 공정에서 파우더가 묻혀진 합사를 꼬면 상기 폴리머분말이 실과 실사이에 끼게 되는 것이다.In the process, when the twisted yarn is buried with powder, the polymer powder is sandwiched between the yarns.

이렇게 연사공정(4)를 거친 합연사는 열풍이 발생되는 건조기(도시 생략)등에 의하여 건조하여 합연사에 포함된 휘발분을 제거하여 합연사(T')의 꼬임형태가 고정되도록 한 후 권취용 보빈등에 권취시키는 건조 및 권취공정(5)를 거쳐 본 발명에 따른 광케이블 방수용 흡수성 합연사가 제조되는 것이다.The twisted yarn that passed through the twisting process (4) is dried by a dryer (not shown) that generates hot air, and removes volatile matter contained in the twisted yarn so that the twisted shape of the twisted yarn (T ') is fixed. After the drying and winding process (5) to be wound, the absorbent twisted yarn for waterproofing the optical cable according to the present invention is manufactured.

도 6는 본 발명의 광케이블용 방수용 흡수성 합연사를 광케이블에 사용된 상태도를 도시한 도면이다.6 is a view showing a state in which the waterproof absorbent twisted yarn for the optical cable of the present invention used in the optical cable.

도 6에 도시된 바와 같이 발명의 방수용 흡수성 합연사(T')는 광케이블(F)의 외주면을 싸는데 사용되는데 광케이블(F)을 나선상으로 감싸 광케이블에 물이 스며들지 못하게 하는 기능을 수행한다.As shown in Figure 6, the waterproof absorbent twisted yarn (T ') of the invention is used to wrap the outer circumferential surface of the optical cable (F) to wrap the optical cable (F) in a spiral function to prevent water from seeping into the optical cable.

즉 광케이블자켓(J) 외부에서 스며든 물이 본 발명의 방수용 흡수성 합연사(T')에 코팅된 고흡수성 폴리머(P)에 흡수되면 더 이상 침투가 되지 못하고 합연사(T')내에 머무르게 되어 광케이블(F)을 물로부터 보호하게 되는 것이다. 즉 본 발명의 방수용 흡수성 합연사(T')는 물과 광케이블에 대하여 버퍼역할을 하는 것이다.That is, when water penetrated outside the optical cable jacket (J) is absorbed by the superabsorbent polymer (P) coated on the waterproof absorbent twisted yarn (T ') of the present invention, it can no longer penetrate and stays in the twisted yarn (T'). To protect the optical cable (F) from water. That is, the waterproof absorbent twisted yarn (T ') of the present invention serves as a buffer for water and optical cables.
