[발명의 상세한 설명]DETAILED DESCRIPTION OF THE INVENTION [
[발명의 목적][Object of the invention]
[발명이 속하는 기술분야 및 그 분야의 종래기술][TECHNICAL FIELD OF THE INVENTION AND RELATED ART OF THE SAME]
본 발명은 카페트용 폴리프로필렌 섬유의 제조방법에 관한 것으로서, 더욱 상세하게는 폴리프로필렌 섬유의 개질 조건을 달리함으로써 부드러운 촉감이 부여되어 카페트 제조용으로 매우 유용한 고감성 폴리프로필렌 섬유의 제조방법에 관한 것이다.The present invention relates to a process for producing polypropylene fibers for carpets, and more particularly, to a process for producing high-sensitivity polypropylene fibers which are very useful for the production of carpets by imparting soft touch by changing the conditions of modification of polypropylene fibers.
일반적으로 폴리프로필렌 섬유를 이용한 성형품은 두께 0.2㎜ 정도의 얇은 것으로 부터 20㎜ 정도의 두꺼운 것까지 용이하게 성형할 수 있는데, 두께가 얇은 것은 포장, 피복재, 침구, 의료용 위생재료, 필터 등의 용도로 사용되고, 두께운 것은 기름 흡착재나 도로공사, 지반개량 등의 토목공사용 재료 및 카페트용 재료로 널리 사용된다. 또한 이러한 폴리프로필렌 섬유를 기재로하여 만든 BCF(Bulk Continuous Filament)는 가볍고, 내약품성, 저흡습성 및 항균성이 뛰어나고, 일광견뢰도가 우수하며 가격이 저렴하여 실내용 또는 옥외용의 카페트용 원사로 넓게 사용되고 있다. 특히 실내용 또는 가정용 카페트의 경우에는 고감성 제품이 요구된다.In general, a molded article made of polypropylene fiber can be easily molded from a thin film having a thickness of about 0.2 mm to a thick film having a thickness of about 20 mm. The thin film can be used for packaging, covering materials, bedding, medical sanitary materials, Thickness is widely used as material for carpentry such as oil absorbent, road work, and ground improvement. In addition, BCF (Bulk Continuous Filament) made from these polypropylene fibers is widely used as yarn for indoor or outdoor carpets because of its light weight, excellent chemical resistance, low hygroscopicity, antibacterial property, excellent light fastness and low price . Especially in case of indoor or domestic carpets, highly sensitive products are required.
미국특허 3,276,944호 및 3,338,922호에서는 폴리프로필렌만을 이용하여 섬유를 제조하는 방법에 대하여 기술하고 있으나, 이 방법으로 제조된 폴리프로필렌 섬유는 상업적인 생산은 용이하지만 부드러운 정도나 벌키성이 떨어지기 때문에 가정용 카페트로는 적합하지가 않다.U.S. Patent Nos. 3,276,944 and 3,338,922 disclose a method for producing fibers using only polypropylene. However, since the polypropylene fiber produced by this method is easy to produce commercially but is poor in softness and bulkiness, Is not suitable.
이러한 결점을 보완하기 위하여 벌키성을 제공하는 방법 및 이를 개선하기 위한 많은 시도가 제안되고 있는데, 이러한 벌키성의 제공 등으로 인하여 기존의 제품에 비하여 촉감면에서는 많은 향상이 있으나, 이러한 벌키성의 제공만으로는 충분히 부드러운 촉감을 가진 폴리프로필렌 카페트를 제조하기가 불충분하다.In order to compensate for these drawbacks, there have been proposed a method for providing a bulky material and many attempts to improve the bulky material. There has been a lot of improvement in the sense of touch as compared with the existing products due to the provision of the bulky material. However, It is insufficient to produce a polypropylene carpet having a soft touch.
또한 일본특허 특개평 7-3528호에는 카페트 제조용 섬유에 사용할 수 있는 수지 조성물에 대하여 기술하고 있다. 이 문헌에서는 폴리에스터 수지를 기본으로하여 변형된 폴리올레핀을 첨가하는 방법을 사용하고 있는데, 이 방법을 사용하여 제조된 섬유는 벌키성이 뛰어나고 유연성이 뛰어난 장점을 가지고 있지만 섬유제조시 부드러운 촉감을 향상시켜 고감성의 섬유를 제조하였다는 점이 명백히 기재되어 있지 않아 커다란 개량효과는 기대되지 않는다.Japanese Patent Laid-Open Publication No. 7-3528 discloses a resin composition which can be used for fibers for producing carpets. In this document, a method of adding a modified polyolefin based on a polyester resin is used. The fiber produced by this method has advantages of excellent flexibility and excellent flexibility, It is not clearly described that high sensitive fibers are produced, and a great improvement effect is not expected.
[발명이 이루고자 하는 기술적 과제][Technical Problem]
본 발명은 상기 종래기술들의 단점들을 해결하기 위한 것으로서, 가공성 및 부드러운 촉감을 가진 폴리프로필렌 카페트를 제공하기 위하여 고감성 폴리프로필렌 섬유의 제조방법을 제공함을 그 목적으로 한다.Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a process for producing a high-sensitivity polypropylene fiber to provide a polypropylene carpet having processability and soft touch.
[발명의 구성 및 작용][Structure and operation of the invention]
본 발명은 폴리프로필렌 섬유를 제조하기 위한 수지를 혼합, 용융, 압축방사하여 섬유를 제조함에 있어서, 폴리프로필렌 섬유를 제조하기 위한 수지로서 90 내지 99mol%의 프로필렌 성분과 1 내지 10mol%의 에틸렌 성분으로 구성되고 용융흐름지수(Melt Index: MI)가 10-30g/10분(230℃에서 측정)인 프로필렌-에틸렌 랜덤 공중합체를 사용하고, 압출방사시 방사팩에서 800-1,500 sec-1의 전단속도하에서 3-20분간 체류시키고 최종 구금공에서 3,000-30,000sec-1의 전단속도 및 200-270℃의 온도에서 압출방사시킴을 특징으로 한다.The present invention relates to a process for producing a polypropylene fiber by mixing, melting and compression-spinning a resin for producing polypropylene fiber, wherein the polypropylene fiber comprises 90 to 99 mol% of a propylene component and 1 to 10 mol% Ethylene random copolymer having a melt index (MI) of 10-30 g / 10 min (measured at 230 DEG C) and having a shear rate of 800-1,500 sec < -1 > At a shear rate of 3,000-30,000 sec < -1 > and a temperature of 200-270 < 0 > C in the final spinneret.
이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
본 발명에서 사용된 프로필렌-에틸렌 랜덤 공중합체는 결정성의 폴리프로필렌계 수지이며, 수평균 분자량은 7,000 내지 800,000, 바람직하기로는 10,000 내지 700,000이고, 또한 용융흐름지수(Melt Index: MI)는 10-30g/10분(230℃에서 측정)인 것이다.The propylene-ethylene random copolymer used in the present invention is a crystalline polypropylene resin and has a number average molecular weight of 7,000 to 800,000, preferably 10,000 to 700,000, and a melt index (MI) of 10-30 g / 10 minutes (measured at 230 占 폚).
일반적으로 결정성 폴리프로필렌계 중합체는 프로필렌의 단일 중합체 또는 랜덤 공중합체로서 예를 들면 통상 지글러-나타(Ziegler-Natta)형 촉매라고 호칭되는 삼염화티탄 및 알킬알루미늄 화합물과의 조합 촉매의 존재하에서 중합시켜 얻을 수 있는데, 중합시 중하온도를 0℃ 내지 300℃까지에 걸쳐서 실시할 수가 있으나 프로필렌의 고입체 규칙성 중합에 있어서 100℃ 이상에서 중합시에는 고도의 일체 규칙성을 갖는 중합체가 얻어지지 않기 때문에 통상 0℃ 내지 100℃의 범위에서 중합을 행하는 것이 적합하다. 중합 압력에 관해서는 특히 제한은 없으나 공업적 또는 경제적이라는 점에서 3 내지 100 기압 정도의 압력이 바람직하며, 또한 중합시 에틸렌이나 1-부텐을 첨가하여도 무방하다.Generally, the crystalline polypropylene-based polymer is polymerized in the presence of a homopolymer or random copolymer of propylene, for example, in the presence of a combination catalyst with a titanium trichloride and an alkyl aluminum compound commonly referred to as a Ziegler-Natta type catalyst The polymerization can be carried out at a mid-low temperature ranging from 0 ° C to 300 ° C, but a polymer having a high degree of unity regularity can not be obtained at the time of polymerization at 100 ° C or more in the high stereoregular polymerization of propylene It is usually preferable to carry out the polymerization in the range of 0 占 폚 to 100 占 폚. The polymerization pressure is not particularly limited, but is preferably from 3 to 100 atmospheric pressure in view of industrial or economical efficiency, and ethylene or 1-butene may be added during polymerization.
본 발명의 경우에는 90 내지 99mol% 의 프로필렌과 1 내지 10mol%의 에틸렌으로 구성된 프로필렌-에틸렌 랜덤 공중합체를 사용하는데, 에틸렌 성분이 10mol% 이상이 되면 부드러운 촉감은 증가하지만 섬유의 물성을 유지하고 있는 프로필렌의 함량이 적어지게 되어 전체적으로 카페트용 폴리프로필렌 섬유의 물성은 불량하게 된다.In the case of the present invention, a propylene-ethylene random copolymer composed of 90 to 99 mol% of propylene and 1 to 10 mol% of ethylene is used. When the ethylene content is more than 10 mol%, the soft touch increases, The content of propylene is reduced and the physical properties of the polypropylene fiber for carpet as a whole are poor.
한편 본 발명에서 상기의 수지를 용융, 압출방사함에 있어서는 상기의 수지를 방사팩에서 800-1,500 sec-1의 전단속도하에서 3-20분간 체류시켜야 한다. 전단 속도가 800sec-1미만이면 폴리머 용융라인 벽면에서 전단응력이 충분하지 않아 가공상 문제점이 생기게 되며, 따라서 최종 섬유에 있어서 부드러운 촉감을 충분히 주지 못하게 된다.In the present invention, in melting and extruding the above-mentioned resin, the resin should be retained in the spinning pack for 3 to 20 minutes under a shear rate of 800-1,500 sec -1 . If the shear rate is less than 800 sec -1 , the shear stress is insufficient at the wall surface of the polymer melt line, which leads to a problem in processing, and thus the softness of the final fiber can not be sufficiently given.
또한 전단속도를 800sec-1이상으로 유지하였다고 하더라도 반드시 고감성 섬유가 제조되는 것은 아니다. 만약 체류시간이 3분 미만인 경우에는 에틸렌 성분이 프로필렌 성분에 충분히 분산되지 않기 때문에 최종제품에 부드러운 촉감을 부여하기가 어렵게 되며, 체류시간이 20분을 초과하는 경우에 있어서는 파이프 내에서의 열분해(thermal degradation)현상이 지나치게 되어 양호한 물성의 섬유를 얻기 힘들게 된다.Even if the shear rate is maintained at 800 sec < -1 > or more, high-sensitivity fibers are not always produced. If the residence time is less than 3 minutes, it is difficult to impart soft touch to the final product because the ethylene component is not sufficiently dispersed in the propylene component. If the residence time exceeds 20 minutes, the thermal decomposition in the pipe degradation phenomenon becomes excessive and it becomes difficult to obtain a fiber having good physical properties.
또한, 본 발명에서는 상기 수지를 방사할 경우, 제조되는 섬유의 부드러운 촉감을 향상시키기 위하여 최종 압출영역인 구금공에서의 전단속도를 3,000-30,000sec-1으로, 온도를 200-270℃로 유지한다. 특히 혼합방사할 경우에 전단속도가 3,000sec-1미만이면 구금공을 나오는 분자쇄의 리코일링(recoiling)이 일어나, 부드러운 촉감을 향상시키는 효과가 미흡하게 되며, 30,000sec-1이상이 되면 폴리머 흐름 상태가 불량하게 된다.Further, if the spinning of the resin in the invention, the shear rate in the final extrusion ball detention area in order to improve the soft touch of the fibers to be produced 3,000-30,000sec - 1, and the temperature was maintained at 200-270 ℃ . Particularly, when the shearing speed is less than 3,000 sec -1 , recoiling of the molecular chains coming out of the spinneret occurs and the effect of improving the soft touch is insufficient. When the shearing speed is more than 30,000 sec -1 , The state becomes poor.
이하, 본 발명을 실시예 및 비교예를 통해 설명하면 다음과 같으며, 본 발명의 범위가 이들 실시예에 의해 한정되는 것은 아니다.Hereinafter, the present invention will be described by way of examples and comparative examples, but the scope of the present invention is not limited by these examples.
