접착용 저융점 단섬유와 이를 이용한 섬유간 접합방법{union method between fiber to use that melting point filament and this for adhesion}Union method between fiber to use that melting point filament and this for adhesion}

본 발명은 접착용 저융점 단섬유와 이를 이용한 섬유간 접합방법에 관한 것으로서,더욱 상세히는 페딩된 여러개의 부직포를 상호 접합시켜 일정두께로 제작되어지는 보온단열재 및 각종 흡음재, 쿠션재 등은 물론이고 그용도 외에도 일정 두께의 섬유를 상호접합이 필요한 경우 그 섬유간 접합(접착)시 보다 신속하고도 간단하게 접합이 이루어지고, 또 융착방법으로 접합됨에 따라서 접합효율이 높으며, 또 공해와 인체에 무해한 환경친화적인 면까지 제공되는 접착용 저융점 단섬유와 이를 이용한 섬유간 접합방법에 관한 것이다.The present invention relates to a low melting point short fiber for bonding and a method of bonding between fibers using the same, and more particularly, a thermal insulation material and various sound-absorbing materials, cushioning materials, etc., which are manufactured to a certain thickness by bonding a plurality of padded nonwoven fabrics to each other. In addition to the use, if a certain thickness of fibers are required to be bonded to each other, the bonding between fibers can be done more quickly and simply, and the bonding efficiency is high due to the bonding method, and the environment is harmless to pollution and human body. The present invention relates to a low melting point short fiber for bonding and fiber bonding using the same.

여러개의 섬유(부직포)를 상호 겹쳐 하나의 제품(보온단열재, 흡음재등)을 생산할 때 종래에는 수용성화학본드, 폐놀계 접착수지 등의 접착제를 각 섬유 사이에 도포한 다음 열처리 과정을 거침으로서 접합시켜왔다.When producing a single product (heat insulating material, sound absorbing material, etc.) by overlapping several fibers (non-woven fabric), conventionally, an adhesive such as a water-soluble chemical bond or a waste phenol-based adhesive resin is applied between the fibers and then bonded by heat treatment. come.

그런데 이러한 방법은 많은 작업시간 및 노동력이 요구됨은 물론 그 접착제가 인체와 공해에 많은 유해성을 가져오게 됨으로 열악한 작업환경과 대기의 공해를 유발시키는 등 많은 문제점을 가지고 있다.However, this method requires a lot of work time and labor, as well as a lot of harmful effects on the human body and pollution, causing poor working environment and pollution of the air.

즉, 여러겹의 섬유를 접착시켜 일정두께의 보온단열재 생산시 하나의 섬유사 일면전체에 상기 화학 접착제를 일일이 도포시킨 다음 다시 그 위에 하나의 섬유를 겹치고 다시 접착제를 바르는 등 이를 반복하는 과정에서 상기 화학 접착제가 배출하는 유독가스 및 심한 악취로 인하여 작업자의 작업환경이 상당히 열악할 수 밖에 없고, 또 작업과정에서 작업자의 신체에 그 접착제가 묻을 경우 그 접착력에 의하여 많은 애로를 겪게 된다.That is, in the process of repeating the above, such as applying the chemical adhesive to the entire one surface of one fiber yarn in order to bond a plurality of fibers to produce a heat insulating material of a certain thickness and then overlap one again and apply the adhesive again on it Due to the toxic gas emitted by the chemical adhesive and severe odor, the working environment of the worker is inevitably poor, and when the adhesive gets on the worker's body in the process of working, the adhesive force suffers a lot of difficulties.

뿐만 아니라 그 유독가스와 냄새는 대기 환경을 오염시키게 됨으로 대기환경 오염의 주요 원인이 되기도 하였다.In addition, the toxic gases and odors have become a major cause of air pollution by contaminating the air environment.

이러한 문제로 인하여 3D업종으로 분류되어 노동인력 확보에 어려움이 발생되고, 또 생산성이 저조하여 제품가격경쟁력이 약화됨은 물론 공해 발생업체로 지목되어 여러 가지 제약이 따르는 등 많은 문제점이 있었다.Due to these problems, it is classified as a 3D industry, which makes it difficult to secure labor force, and also, due to low productivity, the product price competitiveness is weakened, and as a pollution maker, there are many problems such as various restrictions.

이에 본 발명에서는 위와 같은 종래 문제점을 일소하기 위하여 창안한 것으로서, 공해를 전혀 유발시키지 않으면서 신속하고도 간단하게 접착이 이루어 질수 있음은 물론 특히, 접착시 그 접착코자 하는 대상 섬유와 융착 합체되어 접착의 성능 또한 배가될 수 있어 품질의 고급화에도 일조 할 수 있는 저융점 단섬유와 이를 이용한 가장 바람직한 접합방법을 제공함에 주안점을 두고 그 기술적 과제로 완성한 것이다.Accordingly, the present invention was devised to eliminate the above conventional problems, and can be quickly and simply adhered without causing pollution at all, and in particular, is fused and bonded with the target fiber to be bonded. The performance of this product is also doubled, with the focus on providing low melting point short fibers that can contribute to the enhancement of quality and the most preferable bonding method using the same, and completed the technical problem.

위 기술적 과제를 달성하기 위하여 본원에서는 하기 일실시예의 상세한 설명을 통하여 구체적으로 살펴보기로 한다.In order to achieve the above technical problem, the present invention will be described in detail through the following detailed description.

일정 두께의 단열보온재, 각종 흡음재 등의 제조시 섬유와 섬유사이에 유동성 화학접착제를 사용하지 않고, 본원에서는 저융점 섬유사를 이용하여 접착용 저융점 단섬유를 제작한 다음 이를 이용하여 상기 각 섬유사이사이마다 포개어 안착시킨 다음 히팅롤러를 통과시켜 일정 열을 가함으로서 섬유와 섬유사의 저융점 단섬유가 그 열에 의하여 녹아 각 섬유간 일체로 결합되게 하는 것이다.In the manufacture of a heat insulating insulation material of various thicknesses, various sound absorbing materials, and the like without using a fluid chemical adhesive between the fibers, in the present application using a low-melting fiber yarns to produce a low melting point short fibers for bonding using each of the fibers By stacking and seating between the spaces and passing a heating roller to apply a predetermined heat, the low melting point short fibers of the fiber and the fiber yarn are melted by the heat to be integrally bonded to each fiber.

상기한 저융점 단섬유(10)는 폴리프로필렌(Polypropylene)에 염화비닐을 50:50비율로 화합한 단섬유(staple Fiber)를 이용하여 통상의 펀칭공정(통상 단섬유를 이용하여 서로 얽히게 하여 일정 쿠션과 일정두께를 가지게 하는 일반적인 공정)을 거쳐 일정한 두께(얇게)로 형성시킴으로 기존 PP , PE 등 과 같은 합성수지에 비하여 월등하게 융점이 낮은 저융점 섬유원단의 형태로 제작된 것이다.The low melting point short fiber 10 is a regular punching process (usually entangled with each other using a short fiber using a staple fiber in which 50% of polyvinyl chloride is mixed in polypropylene). It is manufactured in the form of low melting point fiber fabric with a much lower melting point than synthetic resins such as PP and PE by forming a certain thickness (thin) through a general process of having a cushion and a certain thickness).

즉, 통상의 폴리프로필렌(Polypropylene) 수지에 염화비닐(화학식 CH2 = CHCl . 상온 .상압(常壓)에서 무색의 기체로, 분자량 62.50, 녹는점 -159.7℃, 끓는점 -13.9℃, 비중 0.969)을 50:50 비율로 혼합함으로서, 상기 폴리프로필렌(Polypropylene 용융점 160℃~200℃)의 단일체의 소재에 비하여 상기 저융점 단섬유의 용융점은 60℃~90℃의 저온에서 완전 용융상태가 될 수 있다.That is, to a conventional polypropylene resin, vinyl chloride (chemical formula CH2 = CHCl. Colorless gas at room temperature and atmospheric pressure, molecular weight 62.50, melting point -159.7 ° C, boiling point -13.9 ° C, specific gravity 0.969). By mixing in a 50:50 ratio, the melting point of the low-melting single fiber may be completely melted at a low temperature of 60 ° C to 90 ° C as compared to a single piece of polypropylene (Polypropylene melting point 160 ℃ ~ 200 ℃).

상기에서 폴리프로필렌과, 염화비닐의 배합비율은 50:50의 비율로 고정되는 것은 아니며 접합원단의 성질에 따라 폴리프로필렌의 배합비율은 다소 높아져도 좋다.The blending ratio of polypropylene and vinyl chloride is not fixed at a ratio of 50:50, and the blending ratio of polypropylene may be somewhat higher depending on the nature of the bonding fabric.

즉, 폴리프로필렌의 배합비율이 높아지면 용융점의 온도가 높아지게 되므로 접착섬유의 용융점이 높은 피 접착 원단에는 사용이 가능하게 되는 것이며 염화비닐의 비율이 높아지면, 용융점은 낮아지게 되나 섬유의 경화 현상이 일어나게 됨으로 염화비닐의 배합비율은 50%를 초과하지 않게 한다.In other words, if the blending ratio of polypropylene is increased, the temperature of the melting point is increased, so that it can be used for the bonded fabric having a high melting point of the adhesive fiber. If the ratio of vinyl chloride is increased, the melting point is decreased, but the hardening phenomenon of the fiber is reduced. This causes the proportion of vinyl chloride to not exceed 50%.

이와 같이 저융점 단섬유는 융점이 낮아 각종 섬유(10)(부직포 등)와 섬유 사이에서 안착시킨 상태에서 히팅롤러(2)에 통과될 때 상기 섬유보다 적은 온도에서 액체상태로 변형이 이루어짐으로 그 히팅롤러(2)의 외압과 더불어 상당한 접착력을 가지게 되고, 또 이와 더불어 도2에서 도시된 바와 같이 순하게 접착되는 차원을 넘어 그 접착코자하는 대상 섬유간 완전 일체와 융착 결합됨에 따라서 단순하게 접착을 실시한 것임에도 불구하고 하나의 단일체 소재로 된 것과 같이 접착성을 최대로 극대화되는 효과를 얻을 수 있다.As such, the low melting point short fiber has a low melting point and is deformed into a liquid state at a temperature lower than that of the fiber when passing through the heating roller 2 in a state of being seated between various fibers 10 (nonwoven fabric, etc.) and the fiber. In addition to the external pressure of the heating roller (2) has a significant adhesive force, and also as shown in Figure 2, beyond the dimension that is gently bonded as shown in Fig. Despite this, it is possible to obtain the effect of maximizing the adhesiveness as one single material.

상기한 히팅롤러(2)의 온도는 접착코자 하는 대상 섬유(1)(각종 부직포, 상기 저융점 단섬유에 비하여 고온의 용융점을 가진 각종 수지섬유 등)의 종류를 고려하고, 그 사이사이에 끼워진 상기 저융점 단섬유(10)에 가해질 수 있는 열을 온도를 감안하여 150℃~300℃까지 선택 유지시킨 상태에서 가동 될 수 있도록 하였다.The temperature of the heating roller 2 is interposed between the target fibers 1 (various nonwoven fabrics, various resin fibers having a high melting point compared to the low melting point short fibers, etc.) to be bonded, and sandwiched therebetween. The heat that can be applied to the low melting point short fiber 10 was allowed to be operated in a state of being selectively maintained at 150 ° C to 300 ° C in consideration of temperature.

이상에서 상술한 바와 같이 본 발명의 고안에서 제시하는 본 발명의 접착용 저융점 단섬유(10)와 이를 이용한 섬유간 접합방법은 섬유와 섬유간 접착시 유동성의 가스 및 악취를 배출하지 않기 때문에 작업환경이 보다 쾌적하게 개선될 수 있음은 물론 대기오염 방지의 효과까지 더불어 제공되며, 특히 이는 취급이 용이하고, 접착코자 하는 대상 섬유간 사이에 간단하게 안착시키기만 하면 됨으로 기존 접착제 도포시 보다 월등한 생산성 향상과 대량생산의 기반을 구축 할 수 있다.As described above, the low melting point short fiber 10 for adhesion of the present invention and the fiber bonding method using the same presented in the present invention do not discharge fluid gas and odor when the fiber is bonded between fibers. Not only can the environment be improved more comfortably, but also the effect of preventing air pollution is provided. In particular, it is easy to handle, and it is superior to existing adhesives simply by simply placing it between the target fibers to be bonded. Improve the productivity and lay the foundation for mass production.

아울러 대상 섬유의 물성에는 전혀 지장을 주지 않는 가운데 접착을 행할 수 있음은 물론 그 접착된 상태가 단순하게 접착되는 차원을 넘어 그 대상섬유간 단일 구조로 완전 융착 일체화 결합됨으로 접착능력 또한 비교할 수 없을 정도로 배가되는 등 고품질 소재 생산에 지대한 공헌을 할 것으로서 기대되는 획기적인 발명이다.In addition, the physical properties of the target fibers can be adhered without any problem, and the bonded state is not only bonded but also fully bonded and integrated into a single structure between the target fibers. It is a revolutionary invention that is expected to make a significant contribution to the production of high quality materials such as doubled.
