본 발명에서 심도있는 청색이라는 것은 청색염료를 사용하여 정해진 농도에 따라 섬유를 청색으로 염색하였을 때 염색물의 염색강도(Dyeing power : 이하 D.P라 한다)가 몰 흡광계수에 비하여 높은 것을 말하며, 빌드업성이 우수하다는 것은 염착성이 좋아 현색성(顯色性)을 장시간 유지하는 성질이 우수하다는 것을 의미한다.In the present invention, the deep blue means that the dyeing power (Dyeing power: hereinafter referred to as DP) of the dye when the fiber is dyed blue according to a predetermined concentration using a blue dye is higher than the molar extinction coefficient. Excellent means good dyeing property and excellent property of maintaining color development for a long time.
종래 셀룰로오즈, 셀룰로오즈/나일론 등과 같은 직물을 청색으로 염색하는데 사용되는 반응성 청색염료로서 대표적인 것들은 대한민국 특허등록 1987-0000218호에서 소개되는 다음 구조식[Ⅳ]의 청색염료와 대한민국 특허등록 1991-0006718호의 실시예 7과 12에서 소개되는 각각 위 구조식[Ⅱ]와 구조식[Ⅲ]으로 표시될 수 있는 다음 구조식[Ⅴ]와 구조식[Ⅵ]의 청색염료가 있다.Reactive blue dyes conventionally used for dyeing fabrics such as cellulose, cellulose / nylon, etc. in blue are representative of the blue dye of the following structural formula [IV] and Korea Patent Registration 1991-0006718, which are introduced in Korean Patent Registration No. 1987-0000218. There are blue dyes of the following structural formulas [V] and [VI] which can be represented by the above structural formulas [II] and [III] respectively, which are introduced in 7 and 12, respectively.
----- [Ⅳ] ----- [Ⅳ]
----- [Ⅴ] ----- [Ⅴ]
----- [Ⅵ] ----- [Ⅵ]
상기 구조식[Ⅴ]와 [Ⅵ]으로 표시되는 청색염료의 경우 빌드업성이 떨어져 진한 색상이 나오지 않는 문제가 있다. 빌드업성 특성은 경제적인 관점에서 뿐만아니라 진하게 착색된 제품을 선호하는 최근의 경향 때문에 중요한 것이며, 따라서 현재 개선의 노력이 이루어지고 있다. 그래서 그동안 많은 연구자들이 심도있는 청색을 보이는 진한 반응성 청색염료를 얻기 위해 많은 노력을 하였음에도 불구하고, 다양한 물성을 만족시킬 수 있는 염료로서는 아직 미흡한 실정에 있다. 예를 들어 상기 구조식[Ⅴ]와 [Ⅵ]으로 표시되는 화합물의 경우에서처럼 심도있는 청색이 나오지 않거나, 상기 구조식[Ⅳ]로 표시되는 화합물에서처럼 진한 반응성 청색염료를 얻은 경우에도 균염성, 발염성 그리고 오염성, 제반견뢰도등에서 불만스러운 경우가 많았다. 여기서 타섬유에 대한 오염성이란 면/나일론 혼방 섬유를 반응성 염료로 염색할 때 반응성 염료는 면에만 염색이 되어야 하는데 나일론에도 약하게 염색되는 것을 말한다.In the case of the blue dyes represented by the structural formulas [V] and [VI], there is a problem that a dark color does not come out due to poor buildup properties. Build-up characteristics are important not only from an economic point of view, but also because of the recent trend to favor darkly colored products, and improvements are currently being made. So many researchers have tried to obtain a deep reactive blue dye showing a deep blue color, but it is still insufficient as a dye that can satisfy a variety of properties. For example, even when the deep blue color does not come out as in the case of the compounds represented by the structural formulas [V] and [VI], or when the dark reactive blue dye is obtained as in the compound represented by the structural formula [IV], Many people were unsatisfied with the pollutants and overall fastness. Contamination to other fibers here means that when dyeing cotton / nylon blended fibers with reactive dyes, the reactive dyes should be dyed only on cotton, but are also weakly dyed on nylon.
따라서 뛰어난 알칼리 안정성으로 콜드패드 염색이 가능하고, 타섬유에 대한 오염성과 제반견뢰도, 균염성이 좋으면서 동시에 염색시 심도있는 청색을 나타내어 적은양으로 높은 D.P를 보이는 환경친화적인 염료의 개발이 요망되는 실정에 있다.Therefore, it is possible to dye cold pads with excellent alkali stability, and it is desirable to develop environmentally friendly dyes that show high levels of DP with small amount of contaminants, good color fastness and good leveling of other fibers and deep blue color at the same time. There is a situation.
본 발명의 목적은 셀룰로오즈, 셀룰로오즈/나일론 등의 직물을 청색으로 염색시 매우 심도있는 청색을 나타내며, 염욕내에 존재하는 알칼리 성분에 대한 안정성이 뛰어나 콜드패드 염색이 가능하고, 제반 견뢰도와 균염성이 뛰어나고, 염색시 셀룰로오즈 이외의 타섬유에 대한 오염성이 적어 원하는 색상을 얻을 수 있으며 수세시 물소비가 적어 폐수량을 감소시킬 수 있는 반응성 청색염료 조성물을 제공하는데 있다.An object of the present invention is very deep blue when dyeing fabrics such as cellulose, cellulose / nylon, and blue, excellent stability to the alkali components present in the salt bath, cold pad dyeing, excellent fastness and uniformity In order to provide a reactive blue dye composition that can reduce the amount of waste water due to less water consumption when washing, since it is less contaminated to other fibers other than cellulose during dyeing.
본 발명자들은 매우 밝은 색상으로 타섬유에 대한 우수한 오염성과 제반견뢰도를 보이는 일반식[Ⅱ]와 [Ⅲ]로 표시되는 염료에 흑색염료를 조성할 때 이용되는 구조식[Ⅰ]로 표시되는 염료(C.I Reactive Black 5등과 같은)를 일정량 함유시켜 염료조성물을 형성시켜 주게되면 염색시 심도있는 청색을 나타내면서 제반견뢰도가 좋고 타섬유에 대한 오염성이 낮은 청색염료 조성물을 얻을 수 있는 것을 확인하여 본 발명을 완성하게 되었다. The inventors have found that the dye represented by the structural formula [I], which is used to form a black dye in the dyes represented by general formulas [II] and [III], which shows excellent staining and overall fastness to other fibers in very bright colors. When a dye composition is formed by containing a certain amount of Reactive Black 5, etc.), the present invention is completed by confirming that a blue dye composition exhibiting a deep blue color at the time of dyeing and having good fastness and low pollution to other fibers can be obtained. It became.
본 발명은 다음 일반식[I]로 표시되는 화합물 30∼80 중량%와 다음 일반식[Ⅱ]로 표시되는 화합물 10∼50 중량% 및 다음 일반식[Ⅲ]으로 표시되는 화합물 10∼50 중량%를 혼합하여서 조성된 반응성 청색염료 조성물에 관한 것이다.The present invention provides 30 to 80% by weight of the compound represented by the following general formula [I], 10 to 50% by weight of the compound represented by the following general formula [II] and 10 to 50% by weight of the compound represented by the following general formula [III] It relates to a reactive blue dye composition formed by mixing.
