Description

나일론 플랫사 {A NYLON FLAT YARN}Nylon Flat Yarn {A NYLON FLAT YARN}

본 고안은 나일론 플랫사에 관한 것으로서, 좀 더 상세히는 나일론필름으로부터 효율좋게 생산할 수 있는 새로운 나일론 플랫사에 관한 것이다.The present invention relates to a nylon flat yarn, and more particularly to a new nylon flat yarn that can be efficiently produced from a nylon film.

종래에 나일론사를 제조하기 위해서는 이른바, 용융방사법으로서, 나일론수지원료인 컴파운드 칩을 용융시켜서 미세한 노즐이 형성된 방사헤드를 통해 방사시켜서 연신 및 냉각 등의 단계를 거쳐서 제작하였다. 그런데, 이러한 용융방사에 의해 제작되는 나일론사는 그 단면이 대체로 원형단면이나 사각형 단면과 같이 종횡비(D/L)가 작다. 따라서, 종래의 나일론사에서는, 필름을 절단하여 제조하는 종횡비가 큰 이른바, 플랫사 또는 슬릿트사에서 얻을 수 있는 것과 같은 질기면서도 거친 질감의 원단을 얻을 수 없었다. 이러한 거칠면서도 질긴 원단은 주로 포장용 로프, 결속끈이나 인테리어재료 또는 가방이나 악세사리의 제조용으로 사용된다.Conventionally, in order to manufacture nylon yarn, as a melt spinning method, a compound chip, which is a nylon water support material, is melted and spun through a spinning head having a fine nozzle to be manufactured through stretching and cooling. However, the nylon yarn produced by such melt spinning has a small aspect ratio (D / L) such that its cross section is generally circular or rectangular. Therefore, in the conventional nylon yarn, the fabric of the tough and coarse texture which is obtained by what is called a flat yarn or a slit yarn with a large aspect ratio which cuts and manufactures a film was not obtained. Such rough and tough fabrics are mainly used for the manufacture of packaging ropes, tie strings or interior materials, or bags or accessories.

한편, 종래에 필름을 절단하여 제작하는 플랫사는 주로 폴리프로필렌이나 HDPE 등의 인조사에 많이 적용되었으나, 나일론사는 T다이를 통해 성형된 필름을 냉각시키는 과정에서 나일론사에 주름이나 변형이 일어나기 쉬어서 나일론사를 플랫사로 제조하는 방법은 실용화되지 못하고 있다. 따라서, 질기고도 내구성이 있으며, 후염가공이 가능한 나일론사의 우수성에도 불구하고 전술한 바와 같이 가방이나 악세사리 등 다양한 제품에 적용되지 못하였다.On the other hand, conventionally, the flat yarn to cut the film has been applied to a lot of polypropylene or HDPE mainly, but the nylon yarn is easy to wrinkle or deformation in the nylon yarn in the process of cooling the film formed through the T-die nylon The method of manufacturing a yarn into a flat yarn has not been put to practical use. Therefore, despite the durability of the tough and durable nylon yarns can be applied to a variety of products such as bags and accessories as described above.

본 고안은 전술한 바와 같은 종래의 플랫사의 다양한 용도에 착안하고, 나일론사의 제조상의 문제점에 착안하여 제안된 것으로서, 나일론사를 플랫사로 제조한 새로운 형태의 나일론 플랫사를 제공하고자 하는 것이다.The present invention focuses on the various uses of conventional flat yarns as described above, and has been proposed in view of problems in the production of nylon yarns, to provide a new type of nylon flat yarns made of nylon yarn flat yarns.

본 고안에 따르면, 나일론수지를 T다이를 통해 필름상으로 압출하고, 압출되는 나일론수지 필름에 에어를 분사하여 외주면이 매끄러운 냉각롤에 접촉시켜서 냉각시키고, 냉각된 나일론필름을 길이방향으로 슬리트하고 연신롤을 통과시켜서 연신시킨 후에, 연신된 나일론사를 다수의 보빈으로 권취하여 얻어지는 것을 특징으로 하는 나일론 플랫사가 제공된다.According to the present invention, the nylon resin is extruded into the film through the T-die, and the air is sprayed onto the extruded nylon resin film so that the outer circumferential surface is brought into contact with a smooth cooling roll, and the cooled nylon film is slit in the longitudinal direction. After passing through the stretching roll to stretch, a nylon flat yarn is provided which is obtained by winding the stretched nylon yarn with a plurality of bobbins.

이하에서 도면을 참조하여 본 고안의 바람직한 실시예를 설명한다. 도 1은 본 고안을 실시하는 장치의 개략 구성도로서, 도시된 바와 같이, 나일론수지 제조용 컴파운드칩을 압출기(10)에서 투입하여 용융시키고 T다이(12)를 통해 필름상으 로 압출한다. 이와같이, 압출된 나일론필름(1)은 T다이(12)에 인접배치된 냉각롤(20)에 접촉되어 냉각된다. 이때, 필름(1)이 냉각롤(20)에 잘 접촉되도록 하기 위해, 에어노즐(22)이 구비되어 미약한 에어를 분사하여 필름(1)을 냉각롤(20)쪽으로 편향시킨다.Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention. 1 is a schematic configuration diagram of an apparatus for carrying out the present invention, as shown, a compound chip for nylon resin production is introduced into an extruder 10 to be melted and extruded into a film through a T-die 12. In this way, the extruded nylon film 1 is brought into contact with the cooling roll 20 disposed adjacent to the T die 12 and cooled. At this time, in order to make the film 1 contact the cooling roll 20 well, an air nozzle 22 is provided to spray the weak air to deflect the film 1 toward the cooling roll 20.

이 냉각롤(20)은 표면이 매끄럽게 마감되고 내부에는 냉각수가 흐르도록 된 것으로서, 형태가 변형될 수 있는 나일론필름(1)이 이 냉각롤(20)의 매끄러운 표면에 접촉되어 통과되므로 나일론필름(1)의 냉각시에 수반될 수 있는 변형이나 주름의 발생을 방지할 수 있다. 이러한 냉각롤(20)을 통한 나일론필름의 냉각방식은, 나일론필름을 냉각공기나 냉각수를 통과시킴으로써 냉각시키려 했던 종래의 방법에서 불가피하게 야기되었던 나일론필름의 변형의 문제를 극복할 수 있게 해 준다.The cooling roll 20 has a smooth surface and a cooling water flows therein, so that the nylon film 1, which can be deformed, passes through and comes into contact with the smooth surface of the cooling roll 20. The occurrence of deformation or wrinkles that may accompany the cooling of 1) can be prevented. The cooling method of the nylon film through the cooling roll 20 allows to overcome the problem of deformation of the nylon film, which was inevitably caused by the conventional method of cooling the nylon film by passing the cooling air or cooling water.

아울러, 바람직하게는 상기 에어노즐(22)은 성형되어 나오는 나일론필름의 폭방향의 양 단부에 배치되어, 필름의 양단부를 중앙부보다 먼저 냉각시킴으로써, 이 양단부가 필름시트에 대한 일종의 프레임과 같은 기능을 수행하여, 필름의 변형이나 주름발생을 더욱 억제하는 효과를 얻을 수 있다.In addition, the air nozzle 22 is preferably disposed at both ends in the width direction of the nylon film being molded, so that both ends of the film are cooled before the center part, so that both ends function as a kind of frame for the film sheet. By carrying out, it is possible to obtain an effect of further suppressing deformation or wrinkle generation of the film.

이와 같이 냉각롤(20)을 통과한 나일론필름(1)은 중간롤(24)을 거쳐서 외주면에 다수의 커터날이 형성된 슬리팅롤(30)을 통과하면서 가늘고 납짝한 슬릿트사, 즉 나일론 플랫사(2)를 이루게 된다. 이와같이 슬리팅단계를 거친 나일론사는 연신기(40)의 연신롤(41)을 거쳐서 연신되고, 최종적으로 다수의 보빈(50)에 권취되어 나일론플랫사를 완성하게 된다. 번호 42는 연신기(40) 내에 배치되어 나일론사가 통과되는 열풍발생기로서, 연신을 촉진하기 위한 것이다.As described above, the nylon film 1 passing through the cooling roll 20 passes through the slitting roll 30 having a plurality of cutter blades formed on the outer circumferential surface thereof through the intermediate roll 24, that is, the slender slits yarn, that is, the nylon flat yarn ( 2) is achieved. The nylon yarn undergoing the slitting step is stretched through the stretching roll 41 of the stretching machine 40 and finally wound around a plurality of bobbins 50 to complete the nylon flat yarn. No. 42 is a hot air generator which is disposed in the drawing machine 40 and passes through nylon yarn, and is for promoting drawing.

이와 같이 제조된 나일론 플랫사는 전술한 바와 같이, 질기면서도 내구성이 있고, 아울러, 제직 후에도 날염이 가능하므로, 가방이나 악세사리와 같이 다소 거칠더라도 충분히 사용이 가능한 제품을 짜서 다양한 디자인의 날염을 적용할 수 있게 되어, 나일론사의 용도를 확대할 수 있는 효과를 달성할 수 있다.As described above, the nylon flat yarn is durable and durable, and can be printed even after weaving. Therefore, it is possible to apply various types of printing by weaving a product that can be used sufficiently even if it is a little rough like a bag or accessories. This can achieve the effect of expanding the use of nylon yarn.

이상에서 설명한 본 고안에 따르면, 질기면서도 내구성이 있는 나일론사를 필름으로 압출하여 냉각롤에 접촉시켜서 냉각시킴으로써, 나일론필름의 냉각과정에서의 변형을 방지하여, 상업적으로 사용가능한 품질수준의 나일론 플랫사를 얻을 수 있다. 이에 따라, 가방이나 악세사리 등, 질기고 질감이 다소 거칠더라도 사용가능한 다양한 제품의 직조에 나일론수지가 사용될 수 있고, 특히, 나일론사의 후염가공이 가능한 점으로 다양한 디자인의 나일론 후염제품을 얻을 수 있다.According to the present invention described above, by extruding a tough and durable nylon yarn into a film and contacting the cooling roll to cool, thereby preventing deformation during the cooling process of the nylon film, nylon flat yarn of a commercially available quality level Can be obtained. Accordingly, nylon resin may be used for weaving various products that can be used even if the texture is rough and rough, such as bags or accessories, and in particular, nylon dyeing products having various designs can be obtained in that the dyeing of nylon yarn is possible.
