Description
본 발명은 습식방사(wet spinning) 혹은 건습식방사(dry-jet wet spinning or air-gap spinning)에 있어서 응고욕조로 방사된 섬유 필라멘트를 고데트롤(godet roll) 혹은 가이드롤(guide roll)로 유도하는 방법 및 장치에 관한 것이다. 보다 구체적으로는 유도관, 유도관에 연결된 파이프라인, 여과망, 및 펌프 등으로 구성된 장치를 이용하여 응고욕 내에서 섬유에 손상을 입히지 않으면서 섬유 필라멘트 다발을 흐트러지지 않게 유도하는 방법에 관한 것이다.The present invention induces a fiber filament spun into a coagulation bath in a wet spinning or dry-jet wet spinning or air-gap spinning with a godet roll or a guide roll. A method and apparatus are provided. More specifically, the present invention relates to a method of inducing fiber filament bundles without disturbing the fibers in the coagulation bath by using a device composed of a guide pipe, a pipeline connected to the guide pipe, a filtering net, a pump, and the like.
습식방사 혹은 건습식방사는 셀루로오즈, 폴리비닐알코올, 폴리아크릴로니트릴, 폴리염화비닐, 폴리아미드 섬유를 방사하는 방법으로 사용되며, 고분자 물질을 용매에 녹여 방사기를 통하여 방사하여 응고욕 내에서 응고시키는 방법을 사용하고 있다. 방사기에서 방사된 섬유 필라멘트는 응고욕 내에서 수평 혹은 수직(상향 혹은 하향)으로 이동하는 동안 응고에 필요한 일정시간 동안을 머물고 다음 공정으로 이동하게 된다. 방사기는 통상적으로 수천개 내지 수만개 이상의 방사돌기(spinnerette)로 구성되어 있으며, 방사된 섬유 필라멘트들은 섬유다발을 형성하게 된다. 응고욕 내에 방사된 섬유 필라멘트들을 다음 공정으로 이송하기 위해서는 섬유다발을 응고욕내 혹은 외부에 설치된 고데트롤까지 유도하여야 하며 이때 수천 또는 수만 개의 섬유 필라멘트를 효과적으로 유도하기가 용이하지 않다. 응고욕내에서 섬유 필라멘트를 수평으로 이동시키는 경우나 수직상향으로 이동시키는 경우에는 응고액을 응고욕의 한쪽에서 투입하고 다른쪽으로 배출시킴으로써 방사된 섬유 필라멘트를 응고액과 함께 흐르도록 유도할 수도 있으나 응고욕내 흐름이 일정하지 않아 작업이 용이하지 않은 단점이 있다.Wet spinning or wet spinning is a method of spinning cellulose, polyvinyl alcohol, polyacrylonitrile, polyvinyl chloride, polyamide fibers, and dissolves the polymer in a solvent and spins it through a spinning machine in a coagulation bath. The method of coagulation is used. The fiber filaments spun from the spinning machine stay in the coagulation bath horizontally or vertically (upward or downwardly) for a certain period of time required to solidify and then move on to the next process. Spinners typically consist of thousands to tens of thousands of spinnerettes, and the spun fiber filaments form a fiber bundle. In order to transfer the fiber filaments spun in the coagulation bath to the next process, the fiber bundle must be guided to gothrol installed inside or outside the coagulation bath, and it is not easy to effectively induce thousands or tens of thousands of fiber filaments. In the case where the fiber filament is moved horizontally or vertically in the coagulation bath, the coagulated fluid may be introduced from one side of the coagulation bath and discharged to the other to induce the spun fiber filament to flow together with the coagulation solution. There is a disadvantage that the work is not easy because the flow is not constant.
특히 건습식방사에서는 통상적으로 수직하향으로 방사하게 되며 방사된 필라멘트들을 응고욕 깊숙이 설치된 고데트롤 또는 가이드롤을 통과하여 응고된 후 다음 공정으로 이송하여야 하므로 응고욕내에서의 섬유다발의 효과적인 유도가 매우 어렵다.In particular, in the wet-and-dry spinning, it is usually difficult to radiate vertically, and it is very difficult to effectively induce the fiber bundle in the coagulation bath because the filaments are spun through the gothrol or guide roll installed deep inside the coagulation bath and then transferred to the next process. .
일반적으로 방사기로부터 응고욕 속으로 처음 들어가는 섬유들은 응고욕 내에서 흐트러지거나 롤러(고데트롤 혹은 가이드롤)에 감겨 이를 한 개의 다발(tow)로 모으기가 매우 힘들다. 또한 종래에 사용하던 갈고리와 같은 도구(도 4 참조)로는 흩어진 필라멘트를 모으기도 어려우며 모아진 섬유가닥을 끊게되는 요인이 되기도 한다. 특히 응고액이 인체에 유해한 경우에는 작업이 더욱 어렵다.In general, fibers first entering the coagulation bath from the radiator are very difficult to disperse in the coagulation bath or to be wound on a roller (gothrol or guide roll) to collect them in a single tow. It is also difficult to collect scattered filaments with a tool such as a conventional hook (see FIG. 4) and may cause a break of the collected fiber strands. Especially when the coagulant solution is harmful to the human body, the operation is more difficult.
습식방사방법을 사용하는 대표적인 섬유인 아크릴섬유 방사에 있어서는 응고액으로 질산 수용액 또는 디메틸포름아미드 수용액을 사용하고 있으며, 폴리아미드 섬유 방사에는 N-메틸피롤리돈과 같은 아미드 용제를 사용한다. 따라서 방사된 섬유 필라멘트를 고데트를 혹은 가이드롤로 유도하기 위해 용매증기가 가득한 분위기에서 작업을 수행하여야 하는 문제점이 있다.In acrylic fiber spinning, which is a representative fiber using the wet spinning method, an aqueous solution of nitric acid or an aqueous dimethylformamide solution is used as a coagulation solution, and an amide solvent such as N-methylpyrrolidone is used for spinning the polyamide fiber. Therefore, there is a problem in that the work must be performed in an atmosphere filled with solvent vapor in order to induce the spun fiber filament to goth or guide rolls.
본 발명의 목적은 상기와 같은 제반문제를 해소하고자 하는 것으로서, 유도관을 이용하여 응고액의 흐름을 일정속도, 일정방향으로 유지함으로써 섬유 필라멘트를 흐트러짐과 손상됨이 없이 흐르는 응고액에 실려 아주 유연하게 유도하고자 하는 것이다.An object of the present invention is to solve the problems described above, by maintaining the flow of the coagulating liquid in a constant speed, a constant direction using an induction pipe, the fiber filament is loaded on the coagulating liquid flowing without being disturbed and damaged very flexibly I want to induce.
보다 구체적으로는 응고욕 내에 본 발명에 의한 유도관을 투입하고 응고액을유도관으로 유입시키는 한편 유도관에는 난류(turbulent flow)가 일어나지 않도록 속도를 유지하고 방향을 조절하여 섬유 필라멘트가 자동적으로 모이게 함으로써 운전자가 원활하게 섬유를 한 다발로 모으는 작업을 수행할 수 있도록 하는 것이다.More specifically, the induction pipe according to the present invention is introduced into the coagulation bath and the coagulating solution is introduced into the induction pipe, while the induction pipe maintains the speed and adjusts the direction so that turbulent flow does not occur so that the fiber filaments are automatically collected. This allows the operator to perform the task of smoothly gathering the fibers in one bundle.

본 발명의 주안점은 응고욕 내에서 응고액의 흐름을 유도하여 방사된 필라멘트가 자연적으로 모이도록 하는 것이다. 이를 성공적으로 성취하기 위한 장치는 응고액의 흐르는 방향 및 속도를 조절할 수 있는 유도관 및 응고액을 순환, 공급하는 펌프를 포함하며, 여과망 또는 바이패스 변과 같은 주변 장치를 포함할 수 있다.The main point of the present invention is to induce the flow of the coagulant liquid in the coagulation bath so that the spun filaments are naturally collected. Apparatus for successfully accomplishing this includes an induction tube capable of adjusting the flow direction and speed of the coagulating liquid and a pump for circulating and supplying the coagulating liquid, and may include a peripheral device such as a filtering network or a bypass valve.
본 발명의 대표적인 장치구성을 예를 들어 설명하면 다음과 같다. 다음의 장치구성 예는 본 발명의 실시를 설명하고자 하는 것이며 발명의 사용 범위 및 실제모양을 제한하는 것이 아니다. 실제 모양은 응고욕의 형태와 구조에 따라 달라질 수 있으며 다양한 모양으로 개조 가능하다.Representative device configurations of the present invention will be described by way of example. The following device configuration examples are intended to illustrate the practice of the invention and do not limit the scope of use and actual appearance of the invention. The actual shape may vary depending on the shape and structure of the coagulation bath and can be modified into various shapes.
응고욕조 내에서 섬유 필라멘트의 수집이 가장 어려운 건습식방사에 본 발명을 적용할 경우, 본 발명에 의한 전체 장치 구성도는 도 1과 같이 나타낼 수 있다. 전체구성은 응고욕조(1); 방사기(2); 고데트롤(3); 응고 욕조 내에서 응고액(8)의 흐름의 방향 및 속도를 조절할 수 있는 유도관(4); 응고액을 순환시키는 펌프(6); 및 여과망(5), 바이패스변(7)과 같은 주변장치로 구성되어 있다.When the present invention is applied to the wet-and-dry spinning where the collection of the fiber filaments in the coagulation bath is the most difficult, the overall device configuration according to the present invention can be represented as shown in FIG. The overall configuration is the coagulation bath (1); Radiator 2; Godetrol (3); An induction tube 4 capable of adjusting the direction and speed of the flow of the coagulating liquid 8 in the coagulation bath; A pump 6 for circulating the coagulating liquid; And peripheral devices such as the filtering net 5 and the bypass valve 7.
유도관의 단면도는 도 2와 같으며 유도관의 개략적 사시도는 도 3과 같다. 이 유도관은 응고 욕조의 응고액을 유도관으로 유도하는 유도깔대기(4b); 펌프로부터 공급된 응고액을 배출하는 반달형 노즐(4a)[또는 스프리트(split)]; 및 응고액이 적당한 유속범위에서 확산되도록 제작된 확산깔대기(4c) 등을 포함한다.A cross-sectional view of the induction pipe is shown in FIG. 2 and a schematic perspective view of the induction pipe is shown in FIG. 3. This induction pipe is an induction funnel (4b) for inducing coagulation fluid in the coagulation bath to the induction pipe; A half moon nozzle 4a (or split) for discharging the coagulating liquid supplied from the pump; And a diffusion funnel 4c prepared to diffuse the coagulation solution in an appropriate flow rate range.
상기 노즐(4a)(또는 스프리트)에는 유도관(4)의 방향과 위치를 조작할 수 있는 손잡이(4d)가 부착되어 있고, 응고액 송출파이프(4e)에는 응고액 송출파이프와 펌프(6)를 연결하기 위한 연결구(4f)가 부착되어 있다. 응고액 송출 파이프와 펌프를 연결하는 연결수단은 일반적인 소재가 사용될 수 있으나, 유연성이 뛰어난 소재가 보다 바람직하다.The nozzle 4a (or split) is provided with a handle 4d for manipulating the direction and position of the induction pipe 4, and the coagulating liquid delivery pipe 4e is provided with a coagulating liquid delivery pipe and a pump 6 The connector 4f for attaching the is attached. As the connecting means for connecting the coagulating liquid delivery pipe and the pump, a general material may be used, but a material having excellent flexibility is more preferable.
상기 유도장치를 이용한 섬유 필라멘트를 유도하는 방법은:The method for deriving the fiber filament using the guide device is:
a) 펌프(6)로부터 공급된 응고액을 유도관노즐(4a)(또는 스프리트)을 통해 확산깔대기(4c)로 배출하고;a) draining the coagulant liquid supplied from the pump 6 to the diffusion funnel 4c through the induction pipe nozzle 4a (or split);
b) 이 배출에 의해 응고욕조의 응고액 및 섬유필라멘트를 유도깔대기(4b)로 유도하고; 및b) directing the coagulating solution and the fiber filaments of the coagulation bath to the induction funnel 4b by this discharge; And
c) 유도된 응고액 및 섬유필라멘트를 단계 a) 보다 낮은 속도로 확산깔대기를 통해 배출시키는 것으로 이루어진다.c) evacuating the coagulated liquor and fiber filaments derived through the diffusion funnel at a lower rate than step a).
이를 보다 구체적으로 설명하면, 펌프(6)로부터 유도관노즐(4a)(또는 스프리트)에 들어오는 응고액은 유도깔대기로 유도되는 응고액보다 빠른 속도를 가지며 확산깔대기(4c)를 통과하면서 응고액의 흐름 속도를 조절, 유지한다.More specifically, the coagulant liquid entering the induction pipe nozzle 4a (or split) from the pump 6 has a higher speed than the coagulant liquid induced by the induction funnel and passes through the diffusion funnel 4c. Adjust and maintain the flow rate.
펌프의 토출량을 조절하던가 바이패스변(7)을 사용하여 유도관노즐(또는 스프리트)에 공급되는 응고액의 유량을 조절함으로써 유도관 내에서 난류가 일어나지 않도록 제어할 수 있다. 이때 유도깔대기(4b) 주변의 유체와 섬유 필라멘트들은 유도관(4)으로 부드럽게 유도 진입되어지며 층류(laminar flow)로 흐르는 유도관내확산깔대기(4c)를 통과하게 된다. 확산깔대기에서 배출되는 유체 혹은 섬유흐름(fiber stream)으로부터 난류의 형성 여부를 육안으로 확인할 수 있다. 유도관내 흐름이 층류를 이루기 위해서는 식 (1)으로 계산되는 레이놀즈수(Re)가 2100 이하이어야 한다. 여기서 D는 대표직경, V는 평균유속, ρ는 액체밀도, μ는 액체의 점도이다.By adjusting the discharge amount of the pump or by adjusting the flow rate of the coagulating liquid supplied to the induction pipe nozzle (or split) by using the bypass valve (7), it is possible to control the turbulence in the induction pipe. At this time, the fluid and fiber filaments around the induction funnel (4b) is guided smoothly into the induction pipe (4) and passes through the induction pipe diffusion funnel (4c) flowing in the laminar flow. The formation of turbulence from the fluid or fiber stream exiting the diffusion funnel can be visually observed. In order to achieve laminar flow in the induction pipe, the Reynolds number Re calculated by Equation (1) must be 2100 or less. Where D is the representative diameter, V is the average velocity, ρ is the liquid density, and μ is the viscosity of the liquid.
이와 같이 고데트롤(3)과 유도관을 통과하여 나온 섬유다발은 운전자에 의해 모아져 다음 공정으로 이어지게 되며 유도관(4)을 응고욕조(1)에서 제거함으로써 목적을 달성하게 되는 것이다.In this way, the fiber bundles passing through the gothrol (3) and the induction pipe is collected by the driver to lead to the next process, and the purpose is achieved by removing the induction pipe (4) from the coagulation bath (1).
본 발명의 장치 및 방법에 의해 습식 및 건습식 방사에 있어서 방사된 섬유 필라멘트들을 흐트러짐 또는 손상됨이 없이 한개의 다발로 유도할 수 있게 되었다.The apparatus and method of the present invention enable the fiber filaments spun in wet and wet spinning to be guided in one bundle without being disturbed or damaged.
