Description
본 발명은 압출코팅방식의 사코팅으로 폴리우레탄수지층을 갖는 코팅사를 제조하는 방법으로서 폴리우레탄수지층과 실과의 접착력이 우수하고 기능성 나노입자가 코팅층표면에만 분포하도록 함으로써 경제성 및 기능성발현에 주안점을 둔 발명이다.The present invention is a method of manufacturing coated yarn with a polyurethane resin layer by yarn coating using an extrusion coating method. The present invention focuses on economic efficiency and functionality by having excellent adhesion between the polyurethane resin layer and the yarn and distributing functional nanoparticles only on the surface of the coating layer. It is an invention with
신발갑피, 가방지, 벽지 등의 제조에 있어서 방수기능, 감촉등의 향상을 위해 여러 가지 직물 소재가 개발되고 있으며, 다양한 기능성을 부여하기 위해 직물에 PVC등의 여러 가지 폴리머를 코팅하여 활용하고 있다.In the manufacture of shoe uppers, bags, wallpaper, etc., various fabric materials are being developed to improve waterproof function and texture, and various polymers such as PVC are coated on fabric to provide various functionality. .
특히, 신축성과 투습방수기능을 부여하기 위해 폴리우레탄 수지를 이용하여 나일론, 면등의 직물에 코팅하여 신발갑피, 가방지, 벽지 등의 다용도로 이용되고 있다. 이러한 PU코팅의 경우 직물이나 편물등에 함침, 트리코트코팅등의 방법으로 코팅을 하고 있으나, 경사 및 위사가 얽힌 상태의 불규칙한 표면과 수많은 기공을 가진 직물, 편물층과 PU수지간의 접착력이 견고하지 못해 장기간 사용이나 세탁의 경우 층간분리현상에 의해 박리현상이 일어나 내구성이 저하되는 경우가 많다.In particular, it is coated with fabrics such as nylon and cotton using polyurethane resin to provide elasticity and moisture-repellent properties, and is used for various purposes such as shoe uppers, bag paper, and wallpaper. In the case of this PU coating, it is applied to fabrics or knitted fabrics using methods such as impregnation or tricot coating, but the adhesion between the knitted fabric layer and the PU resin is not strong due to the fabric having an irregular surface with entangled warp and weft yarns and numerous pores. In the case of long-term use or washing, the durability is often reduced due to peeling due to separation between layers.
이러한 문제점을 해결하기 위해 섬유업계에서는 직물이나 편물의 전단계인 실(원사)에 직접코팅을 하여 박리현상을 해결하고자 하는 연구개발이 활발히 전개되고 있다. 이러한 사코팅의 경우에도 수지에 함침하는 방법의 경우 균일한 코팅이 어렵고, 박리강도가 약하며 코팅층과 직물의 분리가 일어나는 문제점이 있어 압출코팅으로 전환하는 추세로 진행되고 있다.To solve this problem, research and development is being actively conducted in the textile industry to solve the peeling phenomenon by directly coating the thread (yarn), which is the previous step of fabric or knitting. Even in the case of such yarn coating, there are problems in that uniform coating is difficult in the case of resin impregnation, peeling strength is weak, and separation of the coating layer and fabric occurs, so there is a trend of switching to extrusion coating.
한편, 친환경 추세에 발맞추어 바이오 폴리우레탄에 대한 관심이 증대되고 있다. 이러한 바이오매스 유래 폴리올과 이소시아네이트로부터 합성되는 바이오 폴리우레탄은 기존의 석유유래 폴리우레탄에 비해 사용후 폐기되어 분해될 때 CO2 배출량을 10~100% 저감할 수 있으며, 재생가능하여 탄소중립적 친환경적인 소재로 각광받고 있다. 그러나 상기 바이오 폴리우레탄만으로 사코팅을 하는 경우에는 코팅층의 박리강도가 저하되고, 내구성이 취약한 문제가 있었다.Meanwhile, in keeping with eco-friendly trends, interest in bio-polyurethane is increasing. Bio-polyurethane, which is synthesized from biomass-derived polyol and isocyanate, can reduce CO2 emissions by 10-100% when discarded and decomposed after use compared to existing petroleum-derived polyurethane, and is renewable, making it a carbon-neutral, eco-friendly material. is in the spotlight. However, in the case of sand coating using only the bio-polyurethane, there was a problem in that the peel strength of the coating layer was lowered and durability was poor.
그러므로 본 발명에 의하면, 코팅사의 제조에 있어 전체 코팅층을 바이오매스유래 TPU로 하는 경우의 박리강도저하 및 내구성의 취약성을 극복하여 제1차코팅층의 TPU 컴파운드의 TPU는 바이오매스유래 TPU를 사용하여 친환경성을 부여하는 동시에 박리강도의 향상을 이룰수 있어 내구성이 우수하도록 하고, 제1차코팅층의 두께를 최대한 얇게 하여 코어인 원사와의 접착력을 높이고, 제2차코팅층의 두께를 두껍게 하여 기능성을 향상시킨 코팅사를 제공하는 것을 기술적과제로 한다.Therefore, according to the present invention, the decrease in peel strength and vulnerability in durability when the entire coating layer is made of biomass-derived TPU in the production of coated yarn is overcome, and the TPU of the TPU compound of the first coating layer is eco-friendly by using biomass-derived TPU. It provides durability and improves peel strength at the same time, making the first coating layer as thin as possible to increase adhesion to the core yarn, and increasing the thickness of the second coating layer to improve functionality. The technical task is to provide coating yarn.
그러므로 본 발명에 의하면, 폴리우레탄수지층을 갖는 코팅사의 제조방법에 있어서,
원사로서 나일론, 폴리에스테르, 폴리프로필렌 중 어느 하나인 합성섬유사에 2,000~4,000 CPS의 점도를 가지는 바이오매스유래 TPU 컴파운드를 노즐구경 0.25~0.30㎜인 제1압출기로 제1차압출코팅하고 건조시켜 상기 합성섬유사표면에 제1차코팅층을 형성한 후,
은나노분말, 금나노분말, 및 구리나노분말 중 어느 하나 이상을 함유한 TPU 컴파운드를 노즐구경 0.40~0.50㎜인 제2압출기로 제2차압출코팅하고 건조시켜 상기 제1차코팅층표면에 제2차코팅층을 형성하는 것을 특징으로 하는 폴리우레탄수지층을 갖는 코팅사의 제조방법이 제공된다.Therefore, according to the present invention, in the method for manufacturing a coated yarn having a polyurethane resin layer,
As a yarn, a biomass-derived TPU compound with a viscosity of 2,000 to 4,000 CPS is applied to a synthetic fiber yarn made of nylon, polyester, or polypropylene using a first extruder with a nozzle diameter of 0.25 to 0.30 mm and dried.

이하 본 발명을 보다 상세히 설명하기로 한다. Hereinafter, the present invention will be described in more detail.
본 발명은 압출코팅방식의 사코팅으로 폴리우레탄수지층을 갖는 코팅사를 제조하는 방법으로서 폴리우레탄수지층과 실간의 접착력이 우수하고 기능성 나노입자가 코팅층표면에만 분포하도록 함으로써 경제성 및 기능성발현에 주안점을 둔 발명이다.The present invention is a method of manufacturing coated yarn with a polyurethane resin layer by extrusion coating method. The present invention focuses on economic efficiency and functionality by having excellent adhesion between the polyurethane resin layer and the yarn and distributing functional nanoparticles only on the surface of the coating layer. It is an invention with
본 발명의 폴리우레탄수지층을 갖는 코팅사의 제조방법은 원사에 제1차압출코팅 후 기능성 나노입자를 함유한 제2차코팅층을 형성하는 것이 특징이다.The method of manufacturing a coated yarn with a polyurethane resin layer of the present invention is characterized by forming a second coating layer containing functional nanoparticles after first extrusion coating on the yarn.
원사로서는 나일론, 폴리에스테르, 폴리프로필렌 중 어느 하나인 합성섬유사를 사용할 수 있는데, 모노필라멘트사, 멀티필라멘트사, ATY사, DTY사, 방적사의 형태 중 어느 형태의 원사도 가능하다.As the yarn, any synthetic fiber yarn such as nylon, polyester, or polypropylene can be used. Any type of yarn including monofilament yarn, multifilament yarn, ATY yarn, DTY yarn, or spun yarn can be used.
상기 원사에 제1차압출코팅용 TPU 컴파운드를 제1차압출코팅하고 건조시켜 상기 합성섬유사표면에 제1차코팅층을 형성하게 되는데, 상기 제1차코팅층용 TPU 컴파운드는 수성 열가소성 폴리우레탄 수지, 증점제, 소광제, 분산제 등을 함유하는 것으로서 특별한 용제를 필요로 하지 않으며, TPU 컴파운드가 2,000~4,000 CPS의 점도를 가지도록 하여 원사에 압출코팅시 균일하고 접착력이 우수하게 코팅이 되도록 한다. 상기 제1차코팅층의 수성 열가소성 폴리우레탄 수지는 대두유, 피마자유, 옥수수유등의 바이오매스유래 폴리에스터 폴리올과 이소시아네이트호 합성된 열가소성 폴리우레탄 수지(TPU)를 사용하는 것이 바람직한데, 친환경성을 가지도록 할 수 있다.The first extrusion coating TPU compound for the first extrusion coating is applied to the yarn and dried to form a first coating layer on the surface of the synthetic fiber yarn. The TPU compound for the first coating layer is a water-based thermoplastic polyurethane resin, It contains thickeners, matting agents, dispersants, etc. and does not require special solvents. The TPU compound has a viscosity of 2,000 to 4,000 CPS to ensure uniform and excellent adhesion when extrusion coating on yarn. The water-based thermoplastic polyurethane resin of the first coating layer is preferably a thermoplastic polyurethane resin (TPU) synthesized from biomass-derived polyester polyols such as soybean oil, castor oil, and corn oil and isocyanate, so as to be environmentally friendly. can do.
상기 제1차압출코팅후 열풍순환 챔버(180℃)에서 건조를 한 후, 제2차압출코팅을 하게 된다. 제2차압출코팅에서는 상기 제1차코팅층표면에 은나노분말, 금나노분말, 및 구리나노분말 중 어느 하나 이상을 함유한 제2차압출코팅용 TPU 컴파운드를 제2차압출코팅하고 건조시키는데, 상기 제2차압출코팅용 TPU 컴파운드는 수성 열가소성 폴리우레탄 수지, 증점제, 소광제, 분산제이외에 은나노분말, 금나노분말 및 구리나노분말 중 어느 하나 이상을 포함시킨다. 상기 수성 열가소성 폴리우레탄 수지는 바이오매스유래 열가소성 폴리우레탄 수지(TPU)를 사용하여 친환경성을 가지도록 할 수 있다.After the first extrusion coating is dried in a hot air circulation chamber (180°C), the second extrusion coating is performed. In the second extrusion coating, a TPU compound for the second extrusion coating containing at least one of silver nano powder, gold nano powder, and copper nano powder is applied to the surface of the first coating layer and dried. The TPU compound for secondary extrusion coating contains at least one of silver nanopowder, gold nanopowder, and copper nanopowder in addition to water-based thermoplastic polyurethane resin, thickener, matting agent, and dispersant. The water-based thermoplastic polyurethane resin can be made environmentally friendly by using biomass-derived thermoplastic polyurethane resin (TPU).
이렇게 원사표면에 열가소성 폴리우레탄 수지(TPU)층을 형성하여 앨라스토머한 성질을 부여함으로써 유연성과 탄성강도를 높여 신발갑피, 가방지, 인테리어용등으로 활용할 수 있게 된다.In this way, a layer of thermoplastic polyurethane resin (TPU) is formed on the surface of the yarn, giving it elastomer properties, thereby increasing flexibility and elastic strength, allowing it to be used for shoe uppers, bag paper, interior decoration, etc.
상기 은나노분말, 금나노분말, 및 구리나노분말은 코팅사 표면에 은은한 펄과 같은 색상을 부여함과 동시에 항균성 또는 항바이러스성과 같은 기능성을 부여할 수 있다.The silver nanopowder, gold nanopowder, and copper nanopowder can impart a subtle pearl-like color to the surface of the coated yarn and at the same time impart functionality such as antibacterial or antiviral properties.
이와 같이 제1차코팅층표면에 제2차코팅층을 형성하게 되면 제2차코팅층에만 기능성입자가 함유되게 되어 한번의 압출코팅에 기능성입자를 함유시키는 경우보다 경제성이 우수하며, 기능성입자의 기능성 발현에도 보다 효과적이다.In this way, when the second coating layer is formed on the surface of the first coating layer, the functional particles are contained only in the second coating layer, which is superior to the case where the functional particles are included in one extrusion coating, and is also effective in developing the functionality of the functional particles. More effective.
상기 제1차압출코팅시 제1압출기는 노즐구경 0.25~0.30㎜인 압출기이며, 상기 제2차압출코팅시 제2압출기는 노즐구경 0.40~0.50㎜인 압출기인 것이 바람직한데, 제1차코팅층의 두께를 최대한 얇게 하여 코어인 원사와의 접착력을 높이고, 제2차코팅층의 두께를 두껍게 하여 기능성을 향상시킬 수 있다. 또한, 제1차코팅층의 TPU 컴파운드의 TPU는 바이오매스유래 TPU를 사용하여 친환경성을 부여하는 동시에 박리강도의 향상을 이룰 수 있어 내구성이 우수한 코팅사를 제공할 수 있다.In the case of the first extrusion coating, the first extruder is an extruder with a nozzle diameter of 0.25 to 0.30 mm, and in the second extrusion coating, the second extruder is preferably an extruder with a nozzle diameter of 0.40 to 0.50 mm. Adhesion to the core yarn can be increased by reducing the thickness as much as possible, and functionality can be improved by increasing the thickness of the secondary coating layer. In addition, the TPU of the TPU compound of the first coating layer uses biomass-derived TPU, which provides eco-friendliness and improves peel strength at the same time, providing a coating yarn with excellent durability.
그러므로 본 발명에 의하면, 코팅사에 있어서 전체 코팅층을 바이오매스유래 TPU로 하는 경우의 박리강도저하 및 내구성의 취약성을 극복하여 제1차코팅층의 TPU 컴파운드의 TPU는 바이오매스유래 TPU를 사용하여 친환경성을 부여하는 동시에 박리강도의 향상을 이룰수 있어 내구성이 우수하도록 하고, 제1차코팅층의 두께를 최대한 얇게 하여 코어인 원사와의 접착력을 높여 코팅사의 내구성을 향상시키고, 제2차코팅층의 두께를 두껍게 하여 색상발현, 항균성, 항바이러스성등의 기능성을 향상시킨 코팅사를 제공할 수 있다.Therefore, according to the present invention, the decrease in peel strength and vulnerability in durability when the entire coating layer is made of biomass-derived TPU in the coating yarn is overcome, and the TPU of the TPU compound of the first coating layer is eco-friendly by using biomass-derived TPU. At the same time, the peel strength can be improved to ensure excellent durability. The thickness of the first coating layer is made as thin as possible to increase the adhesion to the core yarn, improving the durability of the coated yarn, and the thickness of the second coating layer is thickened. As a result, it is possible to provide coated yarn with improved functionality such as color development, antibacterial properties, and antiviral properties.
