Abstract
Description
본 발명은 자연 조건에서 분해 속도가 적정 수준인, 즉 일정 시간이 흐른 후 저절로 분해될 수 있는 친환경성 폴리프로필렌 섬유에 관한 것이다. The present invention relates to an environmentally friendly polypropylene fiber which can decompose spontaneously at a proper decomposition rate in a natural condition, that is, after a certain period of time.
폴리프로필렌은 석유 정제시 부산물 중 하나인 프로필렌을 중합한 것으로, 중합체가 화학적으로 매우 안정한 아이소택틱 구조를 가져 강도가 우수하며, 또한 수분을 흡수하지 않는 성질을 가지고 있다. 이러한 폴리프로필렌은 원료도 풍부하고 제조법도 간단하면서, 기계적 성질, 열적 성질 및 화학적 성질이 우수하기 때문에 용기, 포장지, 시이트, 필름, 발포체 등의 형태로 잡화, 가전용품, 포장재료, 공업용 부품, 농업용 자재 등 많은 용도에 널리 사용되고 있다. 그러나 사용 후 폐기되는 경우에는 본연의 안정성으로 인해 자연 환경하에서 상당히 장기간 동안 분해되지 않게 되어 오히려 그 우수한 특성이 단점으로 작용하여, 환경 문제를 야기하게 된다. Polypropylene is a polymer of propylene, which is one of the byproducts of petroleum refining. The polymer has an isotactic structure that is chemically very stable and has excellent strength and does not absorb moisture. Such polypropylene is excellent in mechanical properties, thermal properties and chemical properties and is rich in raw materials and easy to manufacture, and therefore can be used as a container, a wrapping paper, a sheet, a film or a foam in the form of articles, household appliances, packaging materials, industrial parts, Materials and so on. However, if it is discarded after use, it will not be decomposed for a long period of time in a natural environment due to its inherent stability, resulting in a disadvantage in its excellent properties, resulting in environmental problems.
폴리프로필렌을 포함하는 범용 플라스틱의 분해를 위해 빛에 의해 분해를 촉진하는 광분해 첨가제, 미생물에 의해 분해를 촉진하는 생분해 수지, 광분해와 생분해를 동시에 일으키게 하는 복합분해 첨가제 등이 연구되어 알려져 있다. 그러나 광분해, 복합분해 첨가제 등도 여전히 분해 기간이 너무 길고, 첨가제의 가격이 고가여서 산업화하는데 어려운 단점이 있으며, 또한 기존의 양산 기계에 그대로 적용하기 어려운 경우가 많다는 문제점이 있다. 또한 폴리유산(PLA) 고분자와 같은 생분해 수지의 경우에는 분해성은 상대적으로 우수하나 물리적인 특성이 취약하고 기존 플라스틱에 비하여 비용이 높다는 단점이 있다. 따라서 기존의 플라스틱과 같이 우수한 물성과 경제성을 지니면서, 자연상에서 스스로 분해되는 친환경적인 소재에 대한 요구가 지속되고 있다. Photodegradation additives for accelerating decomposition by light for biodegradation of general plastics including polypropylene, biodegradable resins for accelerating decomposition by microorganisms, and complex decomposition additives for simultaneously causing photodegradation and biodegradation have been studied. However, the photodegradation, complex decomposition additive and the like still have a disadvantage that the decomposition period is too long and the cost of the additive is so high that it is difficult to industrialize. Further, there is a problem that it is often difficult to apply it to existing mass production machines. In the case of biodegradable resins such as polylactic acid (PLA) polymers, the degradability is relatively good but the physical properties are poor and the cost is higher than that of conventional plastics. Therefore, there is a continuing demand for an environmentally friendly material which is self-decomposing in nature while having superior physical properties and economical properties as conventional plastics.
이에 본 발명은 자연상에서 스스로 분해되는 자가 분해성 폴리프로필렌 섬유를 제공하려고 한다.Accordingly, the present invention seeks to provide a self-degrading self-decomposing polypropylene fiber in nature.
또한 본 발명은 자가 분해성 폴리프로필렌 섬유를 원료로 하여, 사용 후 스스로 분해가 되는 써멀 본드(thermal bond), 니들 펀치(needle punch), 스펀레이스(spunlace) 부직포를 제공하려고 한다.The present invention also provides a thermal bond, a needle punch, and a spunlace nonwoven fabric which are self-decomposable after use, using self-decomposable polypropylene fibers as raw materials.
본 발명은 상기한 목적을 달성하기 위하여, 호모폴리머 폴리프로필렌 99.0~99.95중량%에 대하여 순수 하이드로퍼옥사이드를 0.05~1.0중량%를 포함하는 폴리프로필렌 섬유를 제공한다.In order to achieve the above object, the present invention provides a polypropylene fiber comprising 0.05 to 1.0 wt% of pure hydroperoxide with respect to 99.0 to 99.95 wt% of homopolymer polypropylene.
본 발명은 또한 폴리프로필렌 섬유 전체 중량에 대하여 탄산칼슘을 1.0~20.0중량% 더 포함하는 폴리프로필렌 섬유를 제공한다.The present invention also provides a polypropylene fiber comprising 1.0 to 20.0 weight percent of calcium carbonate based on the total weight of the polypropylene fiber.
본 발명은 또한 하이드로퍼옥사이드가 퀴논 하이드록퍼옥사이드(quinone hydroperoxide), 큐밀 하이드로퍼옥사이드(cumyl hydroperoxide), 디-tert-부틸 퍼옥사이드(di-tert-butyl peroxide), 벤조일 퍼옥사이드(benzoyl peroxide), 아세틸 퍼옥사이드(acetyl peroxide), 디라우릴 퍼옥사이드(dilauryl peroxide), 하이드로젠 퍼옥사이드(hydrogen peroxide), 디아실 퍼옥사이드(diacyl peroxide) 및 퍼옥시디카보네이트(peroxydicarbonate)로 이루어진 군에서 선택되는 1종 이상의 화합물인 폴리프로필렌 섬유를 제공한다.The present invention also relates to a process for the preparation of hydroperoxides wherein the hydroperoxide is selected from the group consisting of quinone hydroperoxide, cumyl hydroperoxide, di-tert-butyl peroxide, benzoyl peroxide, At least one member selected from the group consisting of acetyl peroxide, dilauryl peroxide, hydrogen peroxide, diacyl peroxide and peroxydicarbonate, and at least one member selected from the group consisting of acetyl peroxide, dilauryl peroxide, ≪ / RTI > polypropylene fibers.
본 발명은 또한 섬유 표면에 폴리프로필렌 섬유에 대하여 0.1~1.0중량%의 방사유제로 처리된 폴리프로필렌 섬유를 제공하며, 섬유 표면에 처리한 방사유제는 친수성 또는 소수성 유제를 사용할 수 있다. The present invention also provides polypropylene fibers treated with 0.1 to 1.0 wt.% Of a radiating oil on the surface of the fibers, and the radial emulsions treated on the fiber surfaces can use hydrophilic or hydrophobic emulsions.
본 발명은 또한 본 발명에 따른 폴리프로필렌 섬유로 제조된 써멀 본드, 니들 펀치 및 스펀레이스 부직포를 제공한다.The present invention also provides a thermal bond, needle punch and spun lace nonwoven fabric made of polypropylene fibers according to the present invention.
본 발명의 폴리프로필렌 섬유는 섬유 내에 섬유의 분해 속도를 촉진시킬 수 있는 하이드로퍼옥사이드를 포함하여, 자연상에서 산소와 반응하여 스스로 분해할 수 있을 뿐만 아니라 산소가 희박한 매립 등의 경우에도 하이드로퍼옥사이드에 의해 자가 분해를 위한 라디칼 반응이 가능하다는 장점을 가지고 있다. 또한 탄산칼슘을 더 포함하는 경우에는 분해속도를 최대 60%까지 증가시킬 수 있어, 본 발명에 따르면, 물성은 기존과 같이 우수하면서도 친환경성이 우수한 폴리프로필렌 섬유를 제공할 수 있다. The polypropylene fiber of the present invention contains hydroperoxides capable of accelerating the decomposition rate of fibers in the fibers, and is capable of decomposing itself by reacting with oxygen in nature, and is also capable of decomposing itself into hydroperoxides The radical reaction for self-cleavage is possible. In addition, when calcium carbonate is further contained, the decomposition rate can be increased up to 60%, and according to the present invention, it is possible to provide a polypropylene fiber having excellent physical properties and excellent environment-friendliness.
또한 하이드로퍼옥사이드나 탄산칼슘은 폴리프로필렌 수지 방사시에 첨가하여 사용할 수 있기 때문에 별도의 장비 없이도 용이하게 분해 속도를 가속화할 수 있는 폴리프로필렌 섬유를 제공할 수 있다.Also, since hydroperoxide or calcium carbonate can be added to the polypropylene resin during spinning, it is possible to provide a polypropylene fiber that can accelerate the decomposition rate easily without any additional equipment.
폴리프로필렌 섬유는 열과 빛 등의 에너지에 의해 산소와 반응하여, 퍼옥사이드(peroxide)를 생성한다. 이 퍼옥사이드는 라디칼로 분해되고, 이 라디칼은 다시 폴리프로필렌과 반응하여 라디칼을 재생산하는 라디칼 연쇄반응을 일으켜, 결과적으로 폴리프로필렌이 분해되게 된다. 즉 폴리프로필렌의 분해에는 고분자 라디칼의 생성이 필요한데, 이를 위한 산소와의 반응에 많은 에너지가 필요하게 된다. 본 발명은 폴리프로필렌 섬유 제조시 첨가제로서 라디칼 반응의 개시제로 작용할 수 있는 하이드로퍼옥사이드를 첨가하여, 폴리프로필렌 사이트 내에서 라디칼이 쉽게 형성될 수 있게 하였다. Polypropylene fibers react with oxygen by energy such as heat and light to produce peroxide. This peroxide is decomposed into radicals, which react with the polypropylene again to cause a radical chain reaction to regenerate the radicals, resulting in decomposition of the polypropylene. That is, the decomposition of polypropylene requires the generation of a polymer radical, which requires a lot of energy to react with oxygen. The present invention enables the formation of radicals in the polypropylene site by the addition of hydroperoxide which can act as an initiator of the radical reaction as an additive in the production of polypropylene fibers.
본 발명에 있어서, 폴리프로필렌 섬유는 폴리프로필렌 단독 중합체인 것이 바람직하나, 폴리에틸렌 등의 폴리올레핀과의 랜덤 중합체 또는 블록 공중합체도 사용하는 것이 가능하다.In the present invention, the polypropylene fiber is preferably a polypropylene homopolymer, but it is also possible to use a random polymer or block copolymer with a polyolefin such as polyethylene.
폴리프로필렌 섬유 제조를 위한 방사시 하이드로퍼옥사이드를 첨가제로 첨가하여 사용할 수 있다. 섬유 제조를 위한 별도의 공정이 필요하지 않으며, 통상의 방법에 따라 폴리프로필렌 섬유를 제조할 수 있다. Hydroperoxide may be added as an additive in spinning for the production of polypropylene fibers. A separate process for producing the fiber is not required, and the polypropylene fiber can be produced by a conventional method.
하이드로퍼옥사이드는 ROOH의 일반식을 가지는 과산화물로서, 이는 열 또는 빛 등의 에너지에 의해 쉽게 라디칼로 분해(RO· + ·OH)되어, 폴리프로필렌의 라디칼 분해 반응의 개시제로 작용하며, 산소의 공급에 의해 폴리프로필렌 섬유의 산화를 촉진하여 자가 분해를 돕게 된다. 하이드로퍼옥사이드에 의해 라디칼화된 폴리프로필렌은 산소와의 반응에 의해 연쇄적으로 라디칼화 반응을 일으키게 되어, 일정 기간 사용 후 스스로 분해가 가능하게 된다. 바람직하게 사용될 수 있는 하이드로퍼옥사이드는 퀴논 하이드로퍼옥사이드(quinone hydroperoxide), 큐밀 하이드로퍼옥사이드(cumyl hydroperoxide), 디-tert-부틸 퍼옥사이드(di-tert-butyl peroxide), 벤조일 퍼옥사이드(benzoyl peroxide), 아세틸 퍼옥사이드(acetyl peroxide), 디라우릴 퍼옥사이드(dilauryl peroxide), 하이드로젠 퍼옥사이드(hydrogen peroxide), 디아실 퍼옥사이드(diacyl peroxide) 및 퍼옥시디카보네이트(peroxydicarbonate)가 있으며, 본 발명은 이들 화합물로 이루어진 군에서 선택되는 1종 이상을 사용할 수 있다. 이 중 라디칼화된 후 산화를 보다 촉진할 수 있는 퀴논 하이드로퍼옥사이드가 가장 바람직하게 사용될 수 있다.Hydroperoxide is a peroxide having a general formula of ROOH, which decomposes easily into radicals (RO · + · OH) by energy such as heat or light, acts as an initiator for the radical decomposition reaction of polypropylene, Thereby promoting the oxidation of the polypropylene fiber, thereby assisting self-decomposition. The polypropylene radicalized by hydroperoxide causes a radicalization reaction chain by reaction with oxygen, and decomposition is possible after a certain period of use. Hydroperoxides which can be preferably used include quinone hydroperoxide, cumyl hydroperoxide, di-tert-butyl peroxide, benzoyl peroxide, Diacyl peroxide, and peroxydicarbonate. The present invention relates to a process for producing the same, which comprises reacting these compounds May be used. Among them, quinone hydroperoxide which can promote oxidation after radicalization can be most preferably used.
본 발명에 있어서, 하이드로퍼옥사이드는 순수 하이드로퍼옥사이드로서 폴리프로필렌 섬유에 대하여 0.05~1중량% 포함되는 것이 바람직하며, 보다 바람직하게는 0.1~0.7중량%로 포함되는 것이다. 이는 폴리프로필렌 섬유의 물성의 변화를 초래하지 않으면서, 사용 후 분해를 촉진하기 위해서 적합한 함량에 해당한다.In the present invention, the hydroperoxide is preferably contained in an amount of 0.05 to 1% by weight, more preferably 0.1 to 0.7% by weight, based on the polypropylene fiber as pure hydroperoxide. This corresponds to a content suitable for promoting post-use decomposition without causing a change in the physical properties of the polypropylene fiber.
본 발명의 폴리프로필렌 섬유는 또한 탄산칼슘을 더 포함할 수 있다. 탄산칼슘은 수분을 흡수하여 산화 분해를 촉진하게 되어, 폴리프로필렌 섬유의 자연상에서의 분해를 가속화하게 된다. 탄산칼슘은 폴리프로필렌 섬유에 대하여 1.0~20.0중량% 포함되는 것이 바람직하며, 방사시에 첨가하여 통상의 방법에 따라 폴리프로필렌 섬유로 제조될 수 있다. 상기 범위를 만족하지 않는 경우, 원하는 분해속도를 얻을 수 없거나, 폴리프로필렌 섬유의 강도가 좋지 않게 되어 바람직하지 않다.The polypropylene fibers of the present invention may further comprise calcium carbonate. Calcium carbonate absorbs water and accelerates oxidative decomposition, accelerating the decomposition of natural fiber of polypropylene fiber. The calcium carbonate is preferably contained in an amount of 1.0 to 20.0% by weight based on the polypropylene fiber. The calcium carbonate may be added at the time of spinning, and may be made of polypropylene fiber according to a conventional method. If the above range is not satisfied, a desired decomposition rate can not be obtained, or the strength of the polypropylene fiber becomes poor, which is not preferable.
제조된 폴리프로필렌 섬유는 연신 공정 중에 오일롤러, 오일제트, 침지 또는 스프레이 방식 등에 의해 섬유 표면이 방사유제로 처리되는 것이 바람직하다. 방사유제는 친수성 또는 소수성 부여를 위한 것으로, 불소계, 염소계 또는 실리콘계 방사유제가 제한없이 사용될 수 있다. 제조된 폴리프로필렌 섬유는 통상 써멀 본드, 니들 펀치, 스펀레이스 부직포 형태로 가공되게 되므로, 방사유제는 부직포 제조 공정시 웹의 교락성, 열 접착성 등의 작업성 도모를 위해 폴리프로필렌 섬유에 대하여 0.1~1.0중량%로 포함되는 것이 바람직하다. It is preferable that the fabricated polypropylene fiber is treated with an oil-repellent agent during the stretching process by an oil roller, an oil jet, an immersion or spraying method or the like. Radial emulsions are for imparting hydrophilic or hydrophobic properties, and fluorine-based, chlorine-based or silicone-based dispersions can be used without limitation. Since the produced polypropylene fiber is usually processed in the form of a thermal bond, a needle punch, and a spun lace nonwoven fabric, the radial emulsion is added to the polypropylene fiber in an amount of 0.1 By weight to 1.0% by weight.
한편, 본 발명에 따른 폴리프로필렌 섬유는 써멀 본드, 니들 펀치, 스펀레이스 부직포로 제조될 수 있다. 써멀 본드는 스루에어 본드법, 캘린더법, 극초단파를 이용하는 방법 등 공지된 방법으로 제조될 수 있다. 마찬가지로 니들 펀치, 스펀레이스 부직포도 공지의 방법에 따라 제조될 수 있다.Meanwhile, the polypropylene fiber according to the present invention can be made of a thermal bond, a needle punch, and a spun lace nonwoven fabric. The thermal bond may be produced by a known method such as a through air bonding method, a calendering method, or a method using microwave. Similarly, needle punches and spun lace nonwoven fabrics can be produced by a known method.

열에 의한 분해 테스트는 시편을 130℃의 오븐에서 넣은 후, 일정 시간 간격으로 섬유의 강도 변화를 확인하였다. 또한 빛에 의한 분해 테스트를 위해, 시편을 UV 광원(weatherometer) 하에서 일정 시간 간격으로 강도 변화 확인하였다. 강도는 ASTM 3822에 따라서 평가하였다. 평가 결과를 각각 하기 표 1 및 표 2에 나타내었다. In the thermal decomposition test, the specimens were placed in an oven at 130 ° C., and the change in the strength of the fibers was observed at regular intervals. Also, for the decomposition test by light, the specimens were checked for strength change at a time interval under a UV light weatherometer. The strength was evaluated according to ASTM 3822. The evaluation results are shown in Tables 1 and 2, respectively.
하이드로퍼옥사이드를 포함하는 실시예의 경우 비교예에 비하여 동일한 시간 동안 강도가 더 많이 저하되며, 보다 짧은 시간에 강도가 약해지는 것으로 나타났다. 또, 탄산칼슘을 포함하는 실시예 4의 경우에는 비교예는 물론 다른 실시예에 비해서도 강도가 현저히 짧은 시간 내에 저하되는 것으로 나타났다. In the case of the example including hydroperoxide, the strength was lowered more for the same time period as compared with the comparative example, and the strength was weakened in a shorter time. In addition, in the case of Example 4 including calcium carbonate, the strength was lowered in a remarkably shorter time than the Comparative Example and other Examples.
