Organic Pigment For Textile Printing Pigment In terms of color

We should have heard of organic pigments and dyes to use it, but you know why this is it? I believe that many people do not know the reason. Just when the purchase, the business told you so use, if you ran to ask him why, it is estimated that he did not know it Do not know is not enough, do not say you are proficient, but still have to understand. Xiaobian today to tell you why organic pigments and dyes to use together.

Organic pigments in the color than the dyed bright, high color strength, but the price is also high, so do, for example, POM, PP, PET and other materials when using a lot of organic, we all know is to do POM plastic flowers, he used Surely organic pigments, because the color of the most bright, or he will not make a fortune. But the dye is better than the organic pigment transparency, so a lot of transparent materials are used to do the dye, such as: car taillights, traffic lights and so on.

Why are organic pigments used with dyes?

Because the color of the dye can not reach the brightness of the sample, but if all the organic pigments, then a decentralized effect is not very good, the other is relatively high cost. Of course, there are samples according to the customer to provide color, and many customers to provide samples if the organic and dyes, in the colorimeter above the coordinates of the above can be seen, you can determine which customers use several kinds of C. INO thing, according to the basis of color. The printing products produced by the water-based ink prepared by the dye colorant have the disadvantages of poor water fastness and poor light fastness and easy contamination. In particular, due to the current value of inkjet printing textiles is very high, the requirements of the fastness is also significantly higher than the average fabric.

The use of pigments (paints) for inkjet printing has attracted wide attention. And the size of the pigment particles in the ink during ink jet printing is particularly sensitive to the clogging of the nozzles and the rheology and stability of the ink. Pigment ink is also subject to viscosity restrictions, it is difficult to print darker patterns, which also limits its research and development.

The biggest advantage of pigment colorants is its excellent light fastness and wash fastness. But the pigment is insoluble in water, and therefore, when the water-based ink is prepared using a pigment colorant, the pigment is usually ground into fine powder, dispersed with a surfactant or a polymeric dispersant, suspended in water to form a water- Ink. Water-based ink is thermodynamically unstable, it is difficult to prepare high stability ink with good stability. Due to the surface tension and other reasons, the pigment colorant tends to gather in the water, so the printing color intensity is low, the package is not bright, the pattern is not clear, and easy to plug the nozzle. In addition, the pigment colorant is still incomplete chromatography, color is not bright enough, the preparation of high cost of ink and other shortcomings. So the really fully commercialized pigment inkjet ink is very limited.
