본 발명은 열기구용 고강도 폴리에스테르 직물의 제조방법에 관한 것으로서 고강도 나일론 66필라멘트와 유사한 물성을 발휘하면서도 염색성, 후가공성이 용이하며, 치수안정성, 공기투과도 등의 기능성이 우수한 열기구용 고강도 폴리에스테르 직물에 관한 것이다.The present invention relates to a method for producing a high-strength polyester fabric for hot air balloon, which is similar to high-strength nylon 66 filament, but which has excellent durability, post-processability, dimensional stability and air permeability, .
최근 소비자들의 스포츠 활동영역이 기존 육상스포츠에서 벗어나 스릴감이 넘치는 항공 스포츠레져로 확대되는 추세인데, 이를 위한 항공 스포츠레져용 제품으로서는 열기구, 고공낙하, 패러글라이더 등이 있으며, 제품구성 중 가장 중요한 부품으로 섬유직물이 사용되고 있다. 열기구는 크게 풍선 부분인 구피(envelope), 공기를 데우기 위한 버너, 사람이 타고 장비가 적재되는 바스켓으로 분류되며 구피는 열기구의 부력을 생성하게 되는 가장 중요한 부분이다. 구피에는 강도가 높은 섬유소재가 주로 사용되며 높은 온도와 태양열로 인한 손상 방지를 위해 표면에 폴리우레탄 혹은 실리콘으로 코팅 처리한다.Recently, the sports activity area of consumers has been expanding from the existing athletic sports to the thrilling aviation sports leisure. For the air leisure sports leisure products, there are hot air balloon, high drop, paraglider and so on. Fabrics are being used. Hot air balloons are largely divided into balloons, envelopes, air warmers, and baskets on which people can ride and equipment. The goofy is the most important part of creating balloon buoyancy. Gypsum is mainly made of high strength fiber materials and coated with polyurethane or silicone to prevent damage due to high temperature and solar heat.
국내 기구류에 대한 설계 및 구조에 대한 내용 중 재료 및 부품은 기술기준에 의한 기준에 적합해야하며 정상적으로 사용되고 있는 방법에 따라 장착되어야 하고, 작동 및 퇴화 등을 고려하여 충분한 강도를 가져야하며 경험 및 시험결과에 의해서 적합성, 감항성을 갖춘 것이어야 한다. 특히, 구피 부분은 비행 중 파열 방지를 위해 균열이 확대되지 않도록 응력 집중 부분에는 충분한 강도를 갖도록 설계 및 제작되어야 한다.The materials and parts of the domestic design and structure should be conformed to the standards of the technical standards and should be installed according to the method that is normally used and should have sufficient strength considering the operation and degradation. And shall be of conformity and sensitivity. In particular, the gooseneck should be designed and constructed to have sufficient strength in stress concentration areas to prevent cracks from expanding to prevent rupture during flight.
기본적으로 열기구용 직물은 경량이면서 고강도 특성으로 풍압을 견디는 직물이 적용되어야 하는데, 현재 Nylon66 소재를 주로 사용하고 있다. 이러한 Nylon66 고강력사의 경우, 우수한 강신도 물성과는 달리 염색견뢰도가 낮고, 내후성, 치수안정성 등의 기능성 저하가 문제가 되고 있으며, 후가공성이 폴리에스테르사보다 다소 까다로운 점 등에 의해 최근 Nylon 소재를 대체하기 위한 폴리에스테르 섬유의 활용이 주목받아 오고 있다 .Basically, a hot air balloon fabric should be applied to a fabric that can withstand wind pressure with light weight and high strength. Currently, Nylon66 material is mainly used. These Nylon 66 high strength yarns have a low dye fastness, low resistance to weathering and dimensional stability unlike excellent tenacity properties, and have recently been replaced by Nylon materials due to the somewhat more complicated post-processability than polyester yarns The use of polyester fibers has been attracting attention.
현재 개발되어 있는 폴리에스테르 고강력사는 국내에서 태섬도를 중심으로 개발되고 있으며, 폴리에스테르 세섬사의 경우에는 다양한 기능성 소재로 소개되어 의류/생활용으로 생산되고 있으나 고강도의 특성을 발현하지 못하므로 의류 이외의 용도 접목 시 물성 문제가 발생하고 있다.Polyester high strength yarn developed at present is being developed mainly in Taejun Island in Korea. In case of Polyester Yarn Yarn, it is introduced as various functional materials and is produced for clothing / life use, but since it can not manifest high strength characteristics, There is a physical property problem when it is applied.
그러므로 본 발명에서는 고강도 나일론 66필라멘트와 유사한 물성을 발휘하면서도 염색성, 후가공성이 용이하며, 치수안정성, 공기투과도 등의 기능성이 우수한 열기구용 고강도 폴리에스테르 직물을 제공하는 것을 기술적과제로 한다. Therefore, a technical object of the present invention is to provide a high-strength polyester fabric for a hot air balloon which exhibits similar physical properties as the high-strength nylon 66 filament, but has excellent dyeability, easy post-processability, dimensional stability and air permeability.
그러므로 본 발명에 의하면, 고강도 폴리에스테르 삼각단면 멀티필라멘트를 제직전 사이징하여 사이징픽업율이 6~6.5%가 되도록 하는 사이징공정,Therefore, according to the present invention, the sizing process for sizing the high-strength polyester triangular cross-section multifilament so that the sizing pick-up rate is 6 to 6.5%
상기 사이징된 고강도 폴리에스테르 삼각단면 멀티필라멘트로 정경을 한 후, 고강도 폴리에스테르 삼각단면 멀티필라멘트를 위사로 제직하는 제직공정,High-strength polyester triangular cross-section multifilaments are weighed in a weaving process after sizing with the sizing high-strength polyester triangular cross-section multifilament,
상기 제직후 직물을 합성호발제 1~5g/ℓ, 수산화나트륨 1~5g/ℓ, 탄산나트륨 2~6g/ℓ 및 잔부로서 물을 함유하는 정련제에 90~100℃, 30~40분간 정련 및 호발하는 정련·호발공정으로 이루어지는 것을 특징으로 하는 열기구용 고강도 폴리에스테르 직물의 제조방법이 제공된다.The immediately after fabric is refined and expectorated at 90 to 100 ° C for 30 to 40 minutes in a scouring agent containing 1 to 5 g / l of synthetic promoter, 1 to 5 g / l of sodium hydroxide, 2 to 6 g / l of sodium carbonate and the remainder of water A high-strength polyester fabric for a hot air balloon, characterized by comprising a refining and polishing process.
이하 본 발명을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail.

본 발명에서 사용되는 원사는 종래 열기구용 직물에 사용되던 나일론 66원사를 대체할 수 있는 고강도 폴리에스테르 삼각단면 멀티필라멘트로서 나일론 66와 유사한 물성을 발현하고 염색성, 후가공성이 용이하며, 치수안정성, 공기투과도 등의 기능성이 우수하여 열기구나 낙하산과 같은 경량이면서 고강도 특성으로 풍압을 견디는 항공 스포츠레져용 직물에 사용할 수 있는 고강도 폴리에스테르 삼각단면필라멘트를 사용한다. The yarn used in the present invention is a high-strength polyester triangular cross-section multifilament that can replace nylon 66 yarn used in conventional hot air fabrics. It exhibits similar properties to nylon 66 and has excellent dyeability, post-processability, dimensional stability, High-strength polyester triangular cross-section filaments which can be used for air sports and leisure fabrics that are lightweight and have high strength properties such as heat and parachute due to their excellent functionality such as transparency and the like.
본 발명의 원사인 고강도 폴리에스테르 삼각단면필라멘트는 고유점도 1.0 ~ 1.2 ㎗/g인 폴리에틸렌테레프탈레이트 폴리머를 용융시킨 후, 상기 각모서리에 돌기가 형성된 삼각모양의 방사구금은 돌기폭(W) 0.04~0.06mm, 돌기길이(L) 0.125~0.25 mm인 돌기가 형성되고, 삼각모양의 일변의 길이(A)는 0.217~0.433㎜인 각모서리에 돌기가 형성된 삼각모양의 방사구금을 통해 방사팩 온도 314~316℃, 방사팩압력 135~180bar로 상기 용융된 폴리머를 토출시키고, 토출된 용융상태의 폴리머를 0.43~ 0.45m/sec의 냉각풍이 형성되는 냉각부를 통과시키면서 고화한 후, 연신비 3.84~4.00배로 3단연신하고 오일링을 하고 권취하여 얻은 것을 사용한다.The high strength polyester triangular cross-section filament, which is a source of the present invention, has a triangular-shaped spinneret having a protrusion formed on each corner after melting a polyethylene terephthalate polymer having an intrinsic viscosity of 1.0 to 1.2 dl / g, 0.06 mm and a projection length L of 0.125 to 0.25 mm and a length A of one side of the triangle is 0.217 to 0.433 mm through a triangular spinneret having protrusions at each corner, The molten polymer is discharged at a discharge pressure of 135 to 180 ° C and a discharge pressure of 135 to 180 bar, and the discharged polymer in a molten state is solidified while passing through a cooling part having a cooling wind of 0.43 to 0.45 m / sec. It is made by three shortening, oiling and winding.
상기 고강도 폴리에스테르 삼각단면필라멘트의 제조방법은 크게 용융, 방사, 냉각, 연신 및 권취단계로 이루어지는데, 용융단계에서는 익스트루더에 폴리에틸렌테레프탈레이트 폴리머를 용융시켜 다음단계인 방사단계에 공급하게 된다. 상기 익스트루더는 통상의 합성섬유방사에 사용하는 익스트루더를 사용할 수 있다.The method for producing the high strength polyester triangular cross-section filament consists of melting, spinning, cooling, stretching and winding steps. In the melting step, the extruder melts the polyethylene terephthalate polymer and supplies it to the next spinning step. The extruder may be an extruder used for ordinary synthetic fiber spinning.
본 발명에서 사용되는 상기 폴리에틸렌테레프탈레이트 폴리머는 고유점도 1.0 ~ 1.2 ㎗/g인 것을 사용하는 것이 본 발명의 열기구용 고강도 소재에 바람직하다.The polyethylene terephthalate polymer used in the present invention preferably has an intrinsic viscosity of 1.0 to 1.2 dl / g, which is preferable for the high strength material for hot air balloon of the present invention.
용융온도 265~280℃ 및 유리전이온도 80 ~ 90℃인 폴리머를 사용하는 것이 방사를 안정적으로 할 수 있고, 섬유 형성능, 섬유 발열성 및 고강도부여에 바람직하다.It is preferable to use a polymer having a melting temperature of 265 to 280 ° C. and a glass transition temperature of 80 to 90 ° C. to stabilize spinning and to impart fiber forming ability, fiber heat generating property and high strength.
상기 용융된 폴리머는 방사구금에 공급되어 방사되는데, 상기 방사구금은 도 3에 도시된 것과 같이 설계된 각모서리에 돌기가 형성된 삼각모양의 방사구금을 사용하는데, 돌기폭(W) 0.04~0.06mm, 돌기길이(L) 0.125~0.25 mm인 돌기가 형성되고, 삼각모양의 일변의 길이(A)는 0.217~0.433㎜인 삼각모양의 방사구금이 바람직하다.The molten polymer is supplied to the spinneret and is radiated. The spinneret uses a triangular spinneret having protrusions formed at each corner designed as shown in FIG. 3. The spinneret has a protrusion width (W) of 0.04 to 0.06 mm, It is preferable that a projection having a projection length L of 0.125 to 0.25 mm is formed and a length A of one side of the triangle is 0.217 to 0.433 mm.
방사구가 길이가 짧거나 지름이 크면 방사압력이 낮아져 폴리머가 흘려내려 방사시 왜곡을 일으킬 수 있으며, 길거나 너무 좁으면 폴리머의 체류 시간이 길어져 열화가 일어나거나 방사압력이 높아서 작업성에 문제를 일으킬 수 있다.If the spinneret is short or large in diameter, the spinning pressure may be lowered and the polymer may flow down to cause distortion in spinning. If the spinneret is too long or too narrow, the retention time of the polymer may be prolonged to cause deterioration or high radiation pressure, have.
본 발명의 폴리에스테르의 고분자 유동은 일반적인 I.V 0.65와 달리 고점도 1.V 1.0~1.2로서 점도가 높기 때문에 종래의 "Y"형 방사구금의 경우 방사pack에 완전히 폴리머가 빠져나가질 못해 구금이 막히거나, 구금 조립부분에 폴리머가 새어나오는 등의 문제가 발생하지만, 도 2에 도시된 바와 같은 각모서리에 돌기가 형성된 삼각모양의 방사구금을 사용하게 되면 방사시 pack의 압력을 낮출 수 있고, 방사 구금에서 토출후 필라멘트의 삼각형의 형태가 유지되고, 방사성이 좋아진다.Since the polymer flow of the present invention has a high viscosity of 1.0 to 1.2 and a high viscosity of 1. < RTI ID = 0.0 > 0. < / RTI > 0.65, unlike conventional IV 0.65, the conventional "Y" type spinneret can not completely polymerize into the spin pack, However, if a triangular-shaped spinneret having protrusions formed at each corner as shown in FIG. 2 is used, the pressure of the pack during spinning can be lowered, and in the spinneret The shape of the triangle of the filament after ejection is maintained, and the radioactivity is improved.
이러한 방사구금에 의해 제조된 필라멘트의 단면은 도 2에 도시된 바와 같은 삼각단면으로서 고강도이면서도 원형단면 필라멘트와 대비해 필라멘트 간 공극이 적어 공기투과도가 낮고, 특유의 촉감을 가지며 광택이 뛰어난 특징이 있는 필라멘트를 제공할 수 있다.The cross section of the filament produced by the spinneret is a triangular cross section as shown in Fig. 2, which has a high strength and a low air permeability due to a small gap between the filaments compared to the circular cross section filament, a characteristic tactile feel, Can be provided.
상기 방사구금에서의 방사팩 온도는 314~316℃로 방사팩압력 135~180bar로 하는 것이 열기구용 고강도소재 제조에 적합하다. 상기 방사구금을 통해 동시에 용융방사된 사조는 통상적인 방법과 같이 구금 직하의 사조냉각구간을 통과시키면서 냉각시켜 고화하게 되는데, 토출된 용융상태의 폴리머를 0.43~ 0.45 m/sec의 냉각풍이 형성되는 냉각부를 통과시키면서 고화한다. The temperature of the spinning pack in the spinneret is 314 to 316 캜, and the spinning pack pressure is in the range of 135 to 180 bar, which is suitable for producing a high strength material for a hot air balloon. The yarn which is simultaneously melt-spun through the spinneret is solidified by cooling it while passing through a yarn cooling section of the lower portion of the spinneret as in a conventional method. The molten polymer discharged is cooled to a cooling rate of 0.43 to 0.45 m / Pass through the part and solidify.
이후 제1고뎃롤러, 제2고뎃롤러 및 제3고뎃롤러로 이루어진 연신부에서 연신비 3.84~4.00배로 3단연신하고 오일링을 하고 권취하는데, 연신비 3.84배미만에서는 강도가 약한 문제점이 발생하며, 4.00배를 초과한 경우에는 신도가 떨어지며 단사절이 발생한다. 이렇게 제조된 상기 폴리에스테르 삼각단면필라멘트는 강도6.53~6.70g/d, 신도 16.1~18.96%로서 고강도 Nylon66와 유사한 물성을 발현하면서도 염색성, 후가공성이 용이하며, 치수안정성, 공기투과도 등의 기능성이 우수한 필라멘트로서 본 발명의 열기구용 고강도 폴리에스테르 직물에 사용하기에 바람직하다.Thereafter, in the stretching portion composed of the first godet roller, the second godet roller and the third godet roller, the stretching ratio is 3.84 to 4.00 times and the oil is wound and rolled three times. When the stretching ratio is less than 3.84 times, In the case of exceeding the doubling degree, the elongation is decreased and the thread trimming occurs. The polyester triangular cross-section filament thus produced exhibited similar properties to high-strength Nylon 66, having a strength of 6.53 to 6.70 g / d and an elongation of 16.1 to 18.96%, and was excellent in dyeability, post-processability, dimensional stability and air permeability It is preferably used as a filament in the high tenacity polyester fabric for hot air balloon of the present invention.
