Description

잉크젯 날염용 잉크 조성물{INK COMPOSITION FOR INK-JET TEXTILE PRINTING}[0001] INK COMPOSITION FOR INK-JET TEXTILE PRINTING [0002]

본 발명은 잉크젯 날염용 잉크 조성물에 관한 것으로서, 더욱 상세하게는 잉크의 토출성과 보습성이 좋으며, 셀룰로오스계 섬유 날염 시 발색이 우수한 잉크 조성물에 관한 것이다.The present invention relates to an ink composition for inkjet printing, and more particularly, to an ink composition having excellent ejection properties and moisturizing properties of an ink and excellent color development upon printing with a cellulose-based fiber.

섬유의 고부가가치 실현을 위해 다양한 날염기술들이 제시되어 왔다. 기존의 섬유의 날염 공정은 스크린날염, 로터리날염 등의 방식을 통해 대량 생산 공정을 진행하였다. 그러나 다품종 소량생산가능, 생산공정의 단축(제판공정 불필요), 폐수감소의 장점으로 인해 잉크젯 방식의 프린터 기술 같은 디지털 프린팅 날염기술이 많이 보급 및 전환되고 있다. Various printing technologies have been proposed for realizing high added value of fibers. The existing textile printing process has proceeded through mass production processes such as screen printing and rotary printing. However, digital printing printing technology such as inkjet printer technology is spreading and converting due to advantages of small quantity production, shortening of production process (no plate making process) and reduction of wastewater.

디지털 프린팅 날염기술은 컴퓨터나 그 주변장비를 이용하여 스크린 과정 없이 매우 복잡하고 세밀한 부분까지 선명하게 디자인할 수 있고, 인쇄과정에서 색상의 조합이 자동으로 가능하기 때문에 단일공정으로 날염작업을 수행할 수 있는 장점뿐만 아니라 작업환경 개선이나 환경 부담을 능동적으로 극복할 수 있는 부대효과로 인해 차세대 날염설비로 떠오르고 있다. Digital printing printing technology can be used to design a very complex and detailed part without a screen process by using a computer or its peripheral equipment, and it is possible to automatically print a combination of colors in a printing process. But it is also emerging as the next generation printing facility due to the side effects that can improve the working environment and overcome the environmental burden actively.

하지만 디지털 프린팅 날염기술은 기존방식에 비해 장비의 속도가 느려 생산속도가 느리고, 농색표현이 어려운 단점이 있다. 이로 인해, 잉크젯 프린팅 속도가 향상된 헤드, 장비, 설비가 출시 보급되고, 농색표현의 단점을 개선하기 위해 이에 적합한 고농도 잉크에 대한 니즈가 확대되고 있다.However, the digital printing printing technology has a drawback in that it is slow in production speed and slow in expressing a thick color as compared with the conventional method. As a result, the number of heads, equipment, and facilities with improved ink-jet printing speeds are increasingly being released, and the need for high-density inks suitable for improving the disadvantages of hyperchromatic expressions is expanding.

수성 잉크 조성물은 잉크젯 헤드에서의 토출 안정성을 가지기 위해 표면 장력을 조정할 필요성이 있으며, 수성 잉크 조성물의 상용성, 안정성을 고려하여 적정 종류의 계면활성제를 선택하여 첨가하는 것이 좋다.The aqueous ink composition needs to adjust the surface tension so as to have ejection stability in an ink jet head, and it is preferable to select and add an appropriate type of surfactant in consideration of the compatibility and stability of the aqueous ink composition.

사용량은 표면장력 25 ~ 35 mN/m의 범위를 만족할 수 있는 수준에서 0.1~1 중량부의 범위로 사용하는 것이 바람직하다.The amount used is preferably in the range of 0.1 to 1 part by weight at a level that can satisfy the range of surface tension of 25 to 35 mN / m.

본 발명은 장기간 잉크의 안정성을 확보하기 위하여 pH 조절제 및 방부제를 포함한다.The present invention includes a pH adjusting agent and a preservative in order to secure the stability of the ink for a long period of time.

상기 방부제로는 벤조산나트륨, 소듐피리딘티온-1-옥사이드 및 1,2-벤즈이소티아졸린-3-원(1,2-benzisothiazolin-3-one)로 이루어진 군에서 선택되는 하나 이상을 사용할 수 있다.As the preservative, at least one selected from the group consisting of sodium benzoate, sodium pyridinethione-1-oxide and 1,2-benzisothiazolin-3-one can be used .

When the viscosity is lower than the above range, the ink flows down to the inlet of the printer nozzle, and when the viscosity is high, there is a problem that proper ejection does not occur.

상기 조성물은 Platinum 재질의 Du Nuy Ring Method로 측정하였을 때 표면장력이 20~40 mN/m일 수 있으며, 바람직하게는 25~35 mN/m일 수 있다. 상기 범위보다 낮을 경우에는 잉크가 헤드노즐 주변에 맺히거나 번지게 되어 인쇄된 출력면의 경계가 뚜렷하지 못하고, 상기 범위보다 높은 경우에는 헤드노즐 입구에서 잉크토출이 잘 되지 않고, 잉크방울이 뭉친 상태로 건조되므로 마찰견뢰도가 떨어진다는 문제가 있다.The composition may have a surface tension of from 20 to 40 mN / m, preferably from 25 to 35 mN / m, as measured by a Duane ring method of Platinum. If the range is lower than the above range, the ink is formed or spread around the head nozzle, and the boundary of the printed output surface is not clear. If the range is higher than the above range, ink ejection is not performed well at the head nozzle inlet, There is a problem that the fastness to rubbing is low.
