Description
본 발명은 염착속도가 빠르고 균일한 염색이 가능한 새로운 폴리에스테르 필름 및 그의 염색 방법에 관한 것이다.The present invention relates to a new polyester film capable of fast dyeing with a high dyeing speed and a dyeing method thereof.
통상적으로 폴리에스테르 필름은 분산성 염료 또는 용제성 염료로 염색하고 있으나, 필름 내에 치밀한 결정영역이 50% 이상 존재하기 때문에 염색시 필름 내부로 염료의 확산과 흡착이 잘 일어나지 않아 일반적인 염색 방법으로는 염색이 잘 되지 않는다.Usually, the polyester film is dyed with a disperse dye or a solvent dye. However, since the dense crystal region is present in the film in an amount of 50% or more in the film, diffusion and adsorption of the dye into the film do not occur well during dyeing. It does not work.
이와 같은 문제점 때문에 폴리에스테르 중합시 염료를 첨가한 후 중합체를 압출, 연신하여 원착 폴리에스테르 필름을 제조하는 방법이 실시되기도 한다. 그러나 상기 원착 방법은 다품종 소량 생산이 힘들고, 용융 및 열처리에 견딜 수 있는 고내열성 염료가 요구되는 문제가 있다.In order to solve such a problem, a method of producing a polyester film by extrusion and stretching after adding a dye in polyester polymerization may be carried out. However, there is a problem that it is difficult to produce a small quantity of various products at a low cost, and a high heat resistant dye capable of withstanding melting and heat treatment is required.
한편, 미국특허 5,338,318호에서는 염색캐리어인 글리세롤 트리아세테이트 (Glycerol triacetate)를 사용하여 폴리에스테르 필름을 분산성 염료 혹은 용제형 염료로 염색한 다음, 세정 및 건조하는 연속식 염색 방법이 기재되어 있다. 그러나 상기 방법은 염착속도가 느리고 특히 농색인 경우 염색 색차가 심해 균일 염색이 곤란한 단점이 있다.On the other hand, U.S. Patent No. 5,338,318 discloses a continuous dyeing method in which a polyester film is dyed with a disperse dye or a solvent dye using glycerol triacetate as a dye carrier, followed by washing and drying. However, the above method has a disadvantage in that the dyeing speed is low, especially when the color is high, the dyeing color difference is deep and uniform dyeing is difficult.
이와 같은 문제를 해결하기 위해서, 폴리에스테르 필름 제조시 연신비를 조절하여 필름내 결정성을 저하시켜 염료의 침투 및 확산이 용이한 비결정 영역을 높인 다음, 염색시에는 고온에서 필름을 이완(Relaxation)시키면서 염색하는 방법도 제안, 실시되고 있다. 그러나 상기 방법은 필름의 결정성 부족과 염색시 고온처리에 의해 폴리에스테르 필름의 강도가 저하되는 문제가 있다.In order to solve such a problem, the crystallinity in the film is lowered by controlling the stretching ratio in the production of the polyester film to increase the amorphous region where the dye penetrates and diffuses easily, and then the film is relaxed at high temperature A method of dyeing is proposed and carried out. However, this method has a problem in that the strength of the polyester film is lowered due to the lack of crystallinity of the film and the high-temperature treatment during dyeing.
따라서 본 발명의 목적은 폴리에스테르 필름의 고유 물성을 그대로 유지하면서도 염착속도가 빠르고 균일 염색이 가능한 폴리에스테르 필름 및 그의 염색방법을 제공하기 위한 것이다.
Accordingly, an object of the present invention is to provide a polyester film and a method for dyeing the polyester film, which can maintain a high inherent property of a polyester film while allowing a fast dyeing rate and uniform dyeing.
본 발명은 필름의 물성 저하 없이도 빠른 염착속도로 균일하게 염색이 가능한 폴리에스테르 필름을 제공하고자 한다. 아울러 본 발명은 상기 폴리에스테르 필름을 보다 용이하고도 균일하게 염색 할 수 있는 염색방법을 제공하고자 한다.
The present invention aims to provide a polyester film which can be uniformly dyed at a fast dyeing rate without deteriorating the physical properties of the film. It is another object of the present invention to provide a dyeing method capable of more easily and uniformly dyeing the polyester film.
본 발명은 나프탈렌기를 갖는 단량체가 공중합 되어 있거나 나프탈렌기를 갖는 중합체가 블렌딩 되어 있는 폴리에스테르 필름을 승화성 용제 염료 및 염색캐리어를 사용하여 폴리에스테르 필름의 유리전이온도 보다 높은 온도 하에서 염색한 다음, 연속적으로 세정, 건조함을 특징으로 한다.The present invention relates to a process for dyeing a polyester film in which a monomer having a naphthalene group is copolymerized or a polymer having a naphthalene group is blended by using a sublimable solvent dye and a dye carrier under a temperature higher than the glass transition temperature of the polyester film, Cleaning, and drying.

이하, 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail.
본 발명의 폴리에스테르 필름에는 통상의 방법으로 나프탈렌기를 갖는 단량체가 공중합 되어 있거나 나프탈렌기를 갖는 중합체가 블렌딩 되어 있다. 이때 나프탈렌기를 갖는 단량체 또는 중합체의 함량은 1~98몰%, 더욱 바람직 하기로는 1~94몰% 이다. 나프탈렌기를 갖는 단량체 또는 중합체의 함량이 1몰% 미만인 경우에는 필름의 강도는 유지되나 염색이 잘 되지 않아 균염의 염색 필름 생산이 어렵게 되고, 98몰%를 초과하는 경우에는 염색은 용이하나 필름의 강도가 저하되는 문제가 있다.In the polyester film of the present invention, a monomer having a naphthalene group is copolymerized or a polymer having a naphthalene group is blended by a conventional method. The content of the naphthalene group-containing monomer or polymer is 1 to 98 mol%, more preferably 1 to 94 mol%. When the content of the naphthalene group-containing monomer or polymer is less than 1 mol%, the strength of the film is maintained, but the dyeing is difficult to produce, and the dyeing film of the salt salt is difficult to produce. When the content is more than 98 mol% Is lowered.
본 발명의 필름은 염색캐리어를 사용하여 필름 유리전이온도 보다 높은 온도 하에서 승화성 용제 염료로 쉽게 염색 할 수 있다.The films of the present invention can be readily dyed with sublimable solvent dyes at temperatures above the film glass transition temperature using a dye carrier.

이때 염색캐리어로는 (ⅰ) 물, 에틸렌글리콜, 프로필렌글리콜 등의 글리콜류 화합물, (ⅱ) 글리세롤 트리아세테이트 등의 글리세롤류 화합물, (ⅲ) 리놀산 (Linoleic Acid), 리놀렌산(Linolenic Acid), 올레인산(Oleic Acid), 팔미틴산 (Palmitic Acid) 등의 지방산 글리세롤에스테르 및 (ⅳ) 아마인유(Linseed Oil), 대두유(Soybean Oil), 홍화유(Safflower Oil) 등의 천연 지방산 글리세롤에스테르가 사용 될 수 있다.Examples of the dye carrier include (i) glycol compounds such as water, ethylene glycol and propylene glycol, (ii) glycerol compounds such as glycerol triacetate, (iii) linoleic acid, linolenic acid, Fatty acid glycerol esters such as oleic acid and palmitic acid and (iv) natural fatty acid glycerol esters such as linseed oil, soybean oil and safflower oil.
상기 지방산 글리세롤에스테르는 비점이 230~235℃로 높고, 일반적인 폴리에스테르 염색용 분산염료와 승화성 용제염료에 대해 용해성이 우수하고, 표면 장력이 20 내지 40Dyne/cm로 낮아 폴리에스테르 필름에의 젖음성이 우수하고, 지방산이므로 고온에서도 필름을 침식시키지 않을 뿐만 아니라 인체에 무해하기 때문에 환경 친화적인 염색용 캐리어 이다.The fatty acid glycerol ester has a high boiling point of 230 to 235 DEG C and is excellent in solubility in disperse dyes for general polyester dyeing and sublimable solvent dyes and low in surface tension of 20 to 40 Dyne / Since it is a fatty acid, it does not corrode the film even at a high temperature and is harmless to the human body, so it is an environmentally friendly carrier for dyeing.
본 발명에서는 일정온도 이상에서 승화성(Sublimation)이 우수한 승화성 용제 염료를 사용하여 염착속도를 향상 시킨다. 승화성 염료는 염욕조에서 승화되면서 폴리에스테르 고분자쇄 내부로의 확산이 통상의 용제형이나 분산성 염료보다 빠르다. 그 결과 염착평형에 빨리 도달하게 되어 염착속도도 빨라지게 된다.In the present invention, the dyeing rate is improved by using a sublimable solvent dye excellent in sublimation at a certain temperature or higher. The sublimable dye sublimates in the salt bath and diffuses into the polyester polymer chain faster than the conventional solvent type or disperse dye. As a result, the dyeing equilibrium is quickly reached and the rate of dyeing is also increased.
또한 본 발명의 승화성 용제 염료는 전술한 캐리어에 대한 용해성이 우수하고 열광견뢰도, 자외선 견뢰도가 우수해야 한다. 본 발명에서 사용하는 승화성 용제 염료를 화학적 구조로 구분하면 모노아조계(Monoazo), 디스아조계(Disazo), 퀴놀린계(Quinone), 잔텐계(Xanthene), 안트라퀴논계(Anthraquinone), 금속착제계 (Complex) 등이 있다.In addition, the sublimable solvent dyes of the present invention should have excellent solubility in the above-described carrier, and should have excellent fastness to light and ultraviolet rays. The sublimable solvent dyes used in the present invention can be classified into chemical structures such as monoazo, disazo, quinone, xanthene, anthraquinone, And Complex.
다음은 본 발명의 효과를 극대화 시키기 위한 일련의 제조공정에 대하여 설명한다. Next, a series of manufacturing processes for maximizing the effects of the present invention will be described.
본 발명은 염욕조에서 염색하고 필름 표면에 존재하는 과량의 염료와 캐리어를 제거하는 세정단계, 세정제와 잔존하는 캐리어를 제거하는 건조단계가 연속적으로 일어남으로써 연속식 염색이 가능하게 되는 것이다.The present invention enables continuous dyeing by staining in a salt bath, washing step for removing excess dye and carrier present on the surface of the film, and drying step for removing the cleaning agent and the remaining carrier continuously.
본 발명의 염욕조는 염료와 캐리어를 함유하고 고온으로 가열하므로써 염색속도를 증진시키는 바 적절한 온도는 폴리에스테르 필름의 유리전이 온도 이상으로 특히 120℃ 내지 180℃ 더욱 좋게는 140℃ 내지 160℃ 이다. 염색 시간은 염욕조의 크기에 따라 혹은 필름의 두께에 따라 다르지만 통상 3초 내지 60초 이다.The salt bath of the present invention contains a dye and a carrier and is heated to a high temperature to increase the dyeing speed. The suitable temperature is not lower than the glass transition temperature of the polyester film, especially 120 to 180 ° C, more preferably 140 to 160 ° C. The dyeing time varies depending on the size of the salt bath or the thickness of the film, but is usually from 3 seconds to 60 seconds.
또한 본 발명의 세정조는 전술한 승화성 염료와 캐리어에 대한 친화성이 있는 유기용제를 함유함이 특징이다. 유기용제로는 아세톤, 메틸에틸케톤과 같은 케톤류 화합물이나 에틸아세테이트, 부틸아세테이트와 같은 에스테르류 화합물 등을 사용한다. 본 발명의 세정제는 필름 표면에 묻어 있는 과량의 염료와 캐리어를 상온에서 적절히 제거 할 수 있는 저비점의 유기용제로서 폴리에스테르 필름을 침식시키지 않아야 한다.Further, the cleaning tank of the present invention is characterized by containing the aforementioned sublimable dye and an organic solvent having affinity for the carrier. Examples of the organic solvent include ketone compounds such as acetone and methyl ethyl ketone, and ester compounds such as ethyl acetate and butyl acetate. The cleaning agent of the present invention should not erode the polyester film as an organic solvent having a low boiling point capable of adequately removing excess dyes and carriers on the surface of the film at room temperature.
본 발명의 건조공정은 염색된 필름에 잔존하는 세정제와 캐리어를 증발시키는 열처리 공정이다. 전술한 세정제와 캐리어가 필름 내부에 잔존하면 폴리에스테르 필름의 기계적 물성 저하와 필름의 표면 특성을 변화시키기 때문에 이들의 제거는 필수적 이다. 본 발명의 적절한 열처리 온도는 140℃ 내지 150℃가 적절하고 통상 열풍을 동반하는 것이 보다 효과적 이다.The drying process of the present invention is a heat treatment process for evaporating a cleaning agent and a carrier remaining on a dyed film. If the above-mentioned detergent and carrier remain in the film, it is necessary to remove them because the mechanical properties of the polyester film are deteriorated and the surface characteristics of the film are changed. A suitable heat treatment temperature of the present invention is more preferably 140 to 150 DEG C, and usually accompanied by hot air.
다음은 염액비에 대해서 설명한다. 색상과 필름 두께에 따라 다르지만 담색인 경우 통상 0.1%(wt./volume) 내지 5%(wt./vol.), 농색인 경우 3%(wt./vol.) 내지 15%(wt./vol.)가 적정하다.
The following describes the saline solution ratio. (Wt./volume) to 5% (wt./vol.) In the case of pale color and 3% (wt./vol.) To 15% (wt./vol. .) Is appropriate.
본 발명에 있어서 염착평형 도달시간 및 필름의 각종 특성은 아래와 같은 방법으로 평가 한다.

Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples. However, the present invention is not limited to the following examples.
실시예 1Example 1
나프탈렌기를 함유하는 단량체(디메틸-2,6-나프탈렌디카르복실레이트)의 함량이 1몰% 이고, 두께가 25㎛인 폴리에스테르 필름을 승화성 용제 염료인 솔벤트엘로우 24와 캐리어인 에틸렌글리콜이 함유된 염욕(욕비 : 3.5%)으로 160℃의 온도로 염색한다. 계속해서 이를 메틸에틸케톤과 에탄올이 1 : 1로 혼합된 세정제로 세정시킨 후, 145℃의 온도(열풍 동반)에서 건조한다. 염색시의 염착 평형 도달시간 및 염색 필름의 광학농도 및 균염성을 평가한 결과는 표 2와 같다.A polyester film having a naphthalene group-containing monomer (dimethyl-2,6-naphthalenedicarboxylate) in an amount of 1 mol% and a thickness of 25 mu m was mixed with Solvent Yellow 24 as a sublimable solvent dye and ethylene glycol as a carrier (Bath ratio: 3.5%) at a temperature of 160 캜. Subsequently, this is washed with a cleaning agent mixed with methyl ethyl ketone and ethanol at a ratio of 1: 1, and then dried at a temperature of 145 ° C (accompanied by hot air). Table 2 shows the results of evaluating the arrival time of the equilibrium in dyeing and the optical density and uniformity of the dye film.

필름두께, 필름내 나프탈렌기의 함량 및 염색온도를 표 1과 같이 변경한 것을 제외하고는 실시예 1과 동일한 공정 및 조건으로 폴리에스테르 필름을 염색, 세정, 건조한다. 염색시의 염착 평형 도달시간 및 염색 필름의 광학농도 및 균염성을 평가한 결과는 표 2와 같다.The polyester film was dyed, washed, and dried under the same conditions and conditions as in Example 1 except that the film thickness, the content of naphthalene groups in the film, and the dyeing temperature were changed as shown in Table 1. Table 2 shows the results of evaluating the arrival time of the equilibrium in dyeing and the optical density and uniformity of the dye film.
본 발명의 폴리에스테르 필름은 나프탈렌기를 갖는 단량체가 공중합 되어 있거나 나프탈렌기를 갖는 중합체가 블렌딩 되어 있어서 염착속도가 빨라지고 농염 염색시에도 균일 염색이 가능하다. 또한 본 발명은 염색캐리어를 사용하여 승화성 용제 염로로 본 발명의 폴리에스테르 필름을 염색하므로서 보다 더 염착속도가 빨라지고, 균일 염색 효과를 얻을 수 있다.The polyester film of the present invention can be uniformly dyed even in the case of dyeing with a high dyeing rate because a monomer having a naphthalene group is copolymerized or a polymer having a naphthalene group is blended. Further, the present invention can dye the polyester film of the present invention with a sublimable solvent salt using a dye carrier to achieve a higher dyeing rate and obtain a uniform dyeing effect.
