Description
본 발명은 진한 적색 분산염료 및 이를 이용한 염색방법에 관한 것으로서, 특히 높은 색농도로 염색이 가능하고 염색후에도 견뢰도가 우수한 진한 적색 분산염료 조성물 및 이를 이용한 염색방법에 관한 것이다.The present invention relates to a deep red dispersion dye and a dyeing method using the same, and particularly relates to a deep red dispersion dye composition capable of dyeing at a high color concentration and excellent fastness even after dyeing and a dyeing method using the same.
일반적으로 분산염료는 적색, 황색, 청색의 삼원색의 조합으로 이루어 지며, 이외에 진한 적색(Rubine), 진한 청색(Navy), 흑색(Black) 등의 염료가 함께 사용된다. 이중에 버건디(Burgundy), 보드도(Bordeaux) 등과 같은 진한 적색의 경우 그 색농도의 발현이 쉽지 않으며 염색에 있어서도 색차 발생에 의한 불량 발생이 빈번하여 주의가 요망되는 색영역이다.Generally, the disperse dye is composed of a combination of three primary colors of red, yellow, and blue, and dyes such as dark red, dark blue, and black are used together. Among these, in the case of dark red such as Burgundy and Bordeaux, it is not easy to express the color concentration, and in the dyeing, it is a color gamut that needs attention because of frequent occurrence of color difference.
이러한 진한 적색의 발현을 위해서는 주로 하기 화학식 1과 같은 구조의 염료가 많이 사용되는데, 이는 하기 염료가 높은 염색성 및 색농도의 발현이 용이한 장점을 가지고 있기 때문이다. 그러나 이러한 장점에도 불구하고 제반 견뢰도, 특히 세탁견뢰도가 매우 불량하여 그 사용 농도 및 용도에 제한을 받아 왔다. In order to express such a deep red, dyes of a structure such as the following Formula 1 are mainly used, because the following dyes have advantages of high dyeability and easy expression of color concentration. However, despite these advantages, all of the fastnesses, in particular, the wash fastness has been very poor, has been limited in its concentration and use.
〈화학식 1〉<Formula 1>
이러한 단점을 극복하는 대체 염료로 몇몇 다른 염료들이 추천되고 있으나 색농도가 뚜렷하게 낮아서 진한 적색을 얻기가 어렵다.Several other dyes have been recommended as an alternative dye to overcome this disadvantage, but the color concentration is so low that it is difficult to get dark red.
본 발명자들은 상기 화학식 1의 분산염료가 가지는 단점을 극복하고자 연구중 고견뢰도를 가지는 디에스테르형(Di-Ester type)의 적색 분산 염료와 최적 농도로 혼합한 후, 이 혼합 염료로 염색하면 높은 색농도와 높은 수준의 견뢰도를 동시에 가지수 있다는 것을 알게 되어 본 발명을 완성하게 되었다.The inventors of the present invention, in order to overcome the disadvantages of the disperse dye of the formula (1) mixed with a red disperse dye (Di-Ester type) having a high color fastness at the optimum concentration, and then dyed with the mixed dye high color The present invention has been completed by knowing that it can have a concentration and high level of fastness at the same time.
본 발명의 목적은 진한 적색 분산염료에 있어서, 높은 색농도로 염색이 가능하고 염색후에도 우수한 견뢰도를 가지는 진한 적색 분산염료 조성물을 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a dark red dispersion dye composition which can be dyed at a high color concentration in a deep red dispersion dye and has excellent fastness even after dyeing.

〈실시예 및 비교예〉<Example and Comparative Example>
염색할 폴리에스테르 섬유의 중량 대비 상기 화학식 1의 염료(시노졸 레드 케이-지엘에스이(Synozol Red K-GLSE), 경인양행, 한국) 및 화학식 2의 염료(테라실 레드 더블유4비에스(Terasil Red W4BS), 씨아이비에이 스페셜티 케미칼스(CIBA Specialty Chemicals)사, 스위스)를 하기 표 1과 같은 농도가 되도록 칙량한 후 두 염료를 서로 혼합하여 준비하였다. The dye of the formula 1 (Synozol Red K-GLSE, Kyungin Yang, Korea) and the dye of the formula 2 (Terasil Red W4BS) by weight of the polyester fiber to be dyed ), CIBA Specialty Chemicals (Switzerland, Inc., Switzerland) was adjusted to a concentration as shown in Table 1, and then prepared by mixing the two dyes.
여기에 아세트산 0.3㎖/ℓ, 소디움 아세테이트 2g/ℓ, 분산제(디스퍼 에스-7(Disper S-7), 명성화학(明成化學)사, 일본) 0.5g/ℓ을 첨가한 후 염색할 폴리에스테르 섬유의 중량 대비 15배의 물을 첨가하여 염욕을 준비하였다. 0.3 ml / l of acetic acid, 2 g / l of sodium acetate, and 0.5 g / l of a dispersant (Disper S-7, Sangsung Chemical Co., Japan) were added to the polyester to be dyed. A salt bath was prepared by adding water 15 times the weight of the fiber.
준비된 염욕에 폴리에스테르 섬유를 투입한 후 130℃에서 30분간 염색하였다. 염색이 끝난후 염색물을 물로 세척한 후, 환원 세정(즉, 1g/ℓ의 탄산나트륨, 2g/ℓ의 아황산수소나트륨를 함유하는 용액을 염색물의 중량 대비 15배되는 용액으로 80oC에서 10분간 처리)을 한 다음, 물로 세척하고 건조시켰다.Polyester fiber was added to the prepared salt bath and then dyed at 130 ° C. for 30 minutes. After dyeing, the dye is washed with water, followed by reduction washing (i.e., a solution containing 1 g / l sodium carbonate and 2 g / l sodium bisulfite with a solution that is 15 times the weight of the dye) at 80 o C for 10 minutes. ), Then washed with water and dried.
건조한 폴리에스테르 섬유를 스텐터(Stenter, 마디스(Mathis)사, 스위스)로 180℃에서 1분간 열처리하였다. The dried polyester fibers were heat treated at 180 ° C. for 1 minute with a stent (Stenter, Mathis, Switzerland).
염색한 폴리에스테르 섬유의 세탁견뢰도, 승화견뢰도 및 색농도를 측정 및 평가하여 하기 표 1에 나타내었다. 세탁견뢰도, 승화견뢰도 및 색농도는 다음의 방법으로 측정하였다.Washing fastness, sublimation fastness and color density of the dyed polyester fibers were measured and evaluated, and are shown in Table 1 below. Wash fastness, sublimation fastness and color density were measured by the following method.
1) 세탁견뢰도의 측정 1) Measurement of washing fastness
KS K 0430 A2법에 따라서 세탁견뢰도를 측정하였다. The fastness to washing was measured according to the KS K 0430 A2 method.
2) 승화견뢰도의 측정2) Measurement of sublimation fastness
KS K 0651법에 따라서 승화견뢰도를 측정하였다.Sublimation fastness was measured according to the KS K 0651 method.
3) 색농도의 측정3) Measurement of Color Concentration
화학식 1의 분산염를 염색할 폴리에스테르 섬유의 중량 대비 4%의 농도가 되도록 염색한 염색물의 색농도를 100으로 평가하고 다른 염색물의 색농도를 상대적인 수치로 나타낸다. 색농도의 측정은 분광광도계(컬러-아이 7000에이(Color-Eye 7000A), 멕베스(Macbeth)사)로 측정한 염색 견본의 반사율로부터 K/S값을 계산하였다. The color concentration of the dyed dye was evaluated as 100 to a concentration of 4% relative to the weight of the polyester fiber to dye the dispersion salt of the formula (1) and the color concentration of the other dye is expressed as a relative value. K / S value was calculated from the reflectance of the dyeing swatch measured with a spectrophotometer (Color-Eye 7000A, Macbeth).
이상과 같이 본 발명의 염료 조성물로 염색한 폴리에스테르 섬유는 높은 색농도로 염색될 뿐만 아니라 세탁견뢰도 및 승화견뢰도가 우수하다.As described above, the polyester fiber dyed with the dye composition of the present invention is not only dyed to a high color concentration, but also excellent in washing fastness and sublimation fastness.
