Description
본 발명은 카티온화제를 함유한 잉크젯 날염용 면섬유 전처리제 및 그 처리방법에 관한 것으로서, 구체적으로는 잉크젯 날염방식으로 면섬유를 염색 시 면섬유의 전처리과정에서, 카티온화제가 함유된 전처리제를 사용하여 면섬유를 카티온화시킴으로써 면섬유에 대한 반응성염료의 염색 고착률을 향상시켜 우수한 발색성 및 높은 견뢰도를 가진 잉크젯 날염된 면섬유를 얻도록 하는 것이다.The present invention relates to a cotton fiber pretreatment agent containing a cationizing agent and a method for treating the same, and specifically, in the pretreatment of cotton fibers when dyeing cotton fibers in an inkjet printing method, using a pretreatment containing a cationizing agent Cationizing cotton fibers improves the dyeing fixation rate of reactive dyes on cotton fibers to obtain inkjet printed cotton fibers having excellent color development and high fastness.
일반적으로, 날염이란 섬유의 일부분 또는 무늬의 대부분을 스크린판 등을 사용하여 다양한 색상으로 염색하는 것으로서, 이때 섬유 위에 염액을 그대로 프린팅 할 경우 염액이 번지게 되므로 염액을 호료와 혼합하여 점도 있는 날염색호를 만들어서 그 무늬의 윤곽이 번지지 않도록 염색하는 방법이다.In general, printing is dyeing a part of the fiber or most of the pattern in a variety of colors using a screen plate, etc. At this time, when printing the salt solution on the fiber as it is, the salt solution is spread, so that the dye solution is mixed with the flavoring and printing How to make an arc and dye it so that the outline of the pattern does not spread.
이러한 섬유의 날염기술은 평판날염(스크린날염)이나 롤러날염 등이 주류를 이루고 있으며, 이는 화학섬유의 개발 및 염색산업의 발전에 크게 이바지하여 왔다.The printing technology of such fibers is mainly made of plate printing (screen printing) or roller printing, which has contributed greatly to the development of chemical fibers and the dyeing industry.
그러나, 이와 같은 날염기술은 디자인의 도안에서부터 시작하여 색분해, 제도, 제판 등을 거쳐 샘플제품이 나오기까지 적어도 15일 정도가 소요되는 등 전체적인 가공공정 기간이 긴 편이며, 또한 종래의 날염기술로는 사진 이미지와 같은 복잡한 디자인의 출력에는 한계가 있었다.However, such a printing technique has a long overall processing process, such as at least 15 days from the design of the design to color separation, drafting, engraving, etc., until the sample product comes out. The output of complex designs, such as photographic images, was limited.
이로 인해 잉크젯 날염이 등장하게 되었는데, 잉크젯 날염기술은 컴퓨터의 프린팅 기법을 섬유에 적용하여 섬유원단에 염료를 프린트하는 방법으로서, 컴퓨터 상의 디자인을 바로 섬유에 날염하므로 종래의 날염기술에서 필요로 하는 제판과 색호 조합 단계를 거치지 않는 등 가공공정을 단순화하고, 다품종 소량생산에도 신속하게 응할 수 있게 되어 납기를 최대한 단축시킬 수 있다.This led to the emergence of inkjet printing. Inkjet printing technology is a method of printing dyes on textile fabrics by applying computer printing techniques to textiles. Simplify the processing process without going through the combination of color and color arcs, and can respond quickly to small quantity batch production, thereby reducing the delivery time as much as possible.
또한, 자유로운 색변화 및 디자인의 변경을 유연하게 할 수 있을 뿐만 아니라 제판에 의한 날염공정으로는 불가능한 미묘한 색조표현이 가능한 등 디자인에 있어서 제한이 없으므로 다양한 디자인을 단기간에 처리할 수 있고, 염료와 조제뿐만 아니라 나아가 에너지사용을 극적으로 절감시킬 수 있다.In addition, it is possible to flexibly change the color and design changes freely, as well as to express subtle color tones that cannot be achieved by printing process. Therefore, various designs can be processed in a short period of time. In addition, energy use can be dramatically reduced.
이러한 잉크젯 날염기술이 섬유의 염색에 응용되기 위해서는 컴퓨터와 함께 섬유용 프린터의 하드웨어와 이를 운용하기 위한 소프트웨어, 각종 섬유에 적용 가능한 잉크의 개발 및 염료잉크가 섬유상에 신속하고 효과적으로 고착되도록 하는 전처리제의 개발과 전처리기술 등이 복합적으로 개발되어야 한다.In order to apply the inkjet printing technology to the dyeing of textiles, the hardware of the textile printer, the software for operating the same with the computer, the development of ink applicable to various fibers, and the pretreatment of the dye ink to be fixed on the fibers quickly and effectively Development and pretreatment technology must be developed in combination.
특히, 섬유의 전처리제에 있어서, 만일 섬유에 전처리를 하지 않고 프린팅하는 경우 잉크젯에 의해 염료잉크가 섬유에 출력되는 즉시 번지게 되므로 선명한 색상 및 이미지를 얻을 수 없고, 또한 이를 수세 시 염료잉크의 대부분이 물에 씻겨나가게 되므로 원하는 색상을 얻을 수 없기 때문에, 섬유의 프린팅 전 단계에서 반드시 전처리를 해야만 한다.In particular, in the pretreatment of the fiber, if printing without the pretreatment on the fiber, the dye ink is smeared immediately after being printed on the fiber by inkjet, so that a vivid color and image cannot be obtained, and most of the dye ink when washed Since it is washed off with water, the desired color cannot be obtained, so pretreatment must be done before the fiber is printed.
예컨대, 면섬유의 경우에는 주로 반응성염료로 제조된 잉크가 사용되는데, 이러한 반응성염료는 염색과정에서 공존하는 물에 의해 가수분해되어 다른 종류의 염료에 비해 면섬유에 대한 고착률이 낮아서 수세 시 상당량의 반응성염료가 섬유상에 잘 고착되지 않은 채 씻겨져 나가게 되고, 또한 프린팅 후의 날염무늬의 색상이 원래 의도하는 무늬의 색상에 비해 흐려지는 근본적인 문제점이 있다.For example, in the case of cotton fibers, inks made of reactive dyes are mainly used. These reactive dyes are hydrolyzed by coexisting water in the dyeing process, so that the adhesion rate to cotton fibers is lower than that of other types of dyes. There is a fundamental problem that the dye is washed off without sticking well to the fiber, the color of the printed pattern after printing is blurred compared to the color of the original intended pattern.
또한, 무늬 염에 있어서 염료의 색상이 단일색상이 아닌 여러 가지 색상으로 혼합된 경우가 많은데, 이때 각각의 색상을 지닌 반응성염료가 섬유상에 균일하게 고착되지 않고 수세 시에도 불균일하게 씻겨 나가게 되어 섬유에 염색된 무늬의 최종 색상은 원본의 색상과는 상당부분 달라지게 된다는 단점이 있었다.In addition, in the case of the pattern salt, the color of the dye is often mixed in various colors instead of a single color, wherein the reactive dyes having the respective colors are not uniformly fixed on the fiber and are washed out unevenly upon washing with water. The final color of the dyed pattern has the disadvantage that it is quite different from the original color.
이러한 문제점을 해결하기 위한 종래의 기술로서, 국내 특허공개번호 제96-007930호의 반응성염료에 의해 면섬유 염색성을 향상시킨 염색물의 제조방법이 공지되어 있다.As a conventional technique for solving this problem, there is known a method for producing a dyeing material that improves the dyeing of cotton fibers by the reactive dyes of Korean Patent Publication No. 96-007930.
그러나, 상기 공지기술은 양이온화제와 기타 약제를 물에 녹인 용액에 면섬유를 넣고 일정온도에서 일정시간 동안 처리함으로써 물 속의 양이온화제가 섬유에 부착되도록 한 후 염색하는 것으로서, 이는 침염기술을 이용하여 면섬유를 염색하는 것이므로 다양한 색상으로 염색할 수 없을 뿐만 아니라 이로 인해 디자인의 변경을 자유롭게 할 수 없다는 단점을 지니고 있다.However, the known technique is to dye cotton after the cationic agent in the water is attached to the fiber by putting a cotton fiber in a solution in which the cationic agent and other drugs are dissolved in water and treated for a predetermined time at a predetermined temperature, which is a cotton fiber by using a dyeing technique It is not possible to dye in a variety of colors because it is dyed, and this has the disadvantage that it is not possible to change the design freely.
이에 따라, 본 발명에서는 잉크젯 날염기술로 면섬유를 염색하는 경우 면섬유를 전처리 시 종래의 전처리제에 카티온화제를 일부 혼합하여 면섬유를 카티온화(양이온화)시킴으로써 음이온성의 반응성염료를 정전기적 인력에 의해 면섬유 상에 효과적으로 흡착시켜 고착되도록 하였다.Accordingly, in the present invention, when dyeing the cotton fibers by inkjet printing technology, when the cotton fibers are pretreated, a portion of the cationic agent is mixed with a conventional pretreatment agent to cationic (cationize) the cotton fibers to electrostatic anion dyes by electrostatic attraction. It was effectively adsorbed onto cotton fibers to allow them to adhere.
또한, 본 발명에서 이용되는 면섬유의 전처리제로서는 공지의 천연 혹은 합성의 수용성고분자와, 증열 시 염료의 용해도를 증가시키고 섬유 내의 함수율을 증가시키는 요소 또는 티오요소와, 반응성염료를 면섬유에 화학적으로 결합시키기 위한 알칼리성 물질 및 면섬유에 대한 반응성염료의 흡착성을 높이는 중성염에, 본 발명에 있어서의 카티온화제를 더 첨가하여 각각 일정 비율로 혼합하여 전처리제를 제조하여 사용한다.In addition, as a pretreatment agent for cotton fibers used in the present invention, known natural or synthetic water-soluble polymers, urea or thiourea which increase the solubility of dyes and increase the water content in the fiber during steaming, and reactive dyes are chemically bonded to cotton fibers. To the neutral salt which improves the adsorption property of the reactive dye with respect to the alkaline substance and cotton fiber for further addition, the cationizing agent of this invention is further added, and it mixes in a fixed ratio, respectively, and prepares and uses a pretreatment agent.
본 발명은 상기와 같은 문제점을 해결하기 위하여 개발된 것으로서, 본 발명의 잉크젯 날염용 면섬유 전처리제 및 그 처리방법은 면섬유의 잉크젯 날염 시 면섬유에 대한 반응성염료의 고착률을 향상시킴으로써 우수한 발색성과 높은 견뢰도를 나타내도록 하는 것을 목적으로 한다.The present invention was developed to solve the above problems, the inkjet printing cotton fiber pretreatment agent and the method of treatment of the present invention by improving the adhesion rate of the reactive dye to the cotton fiber during inkjet printing of the cotton fiber excellent color development and high fastness The purpose is to indicate.
또한, 본 발명은 잉크젯 날염된 면섬유의 색상과 원본 상의 색상의 유사도를 향상시키도록 하는 것이다.In addition, the present invention is to improve the similarity between the color of the inkjet printed cotton fiber and the color on the original.
