Background
The pigment printing is suitable for different types of fibers and blended fabrics thereof, and is a printing method which is more, faster, better and less in cost. But the defects are that the method is not suitable for printing on the surface of a dark fabric, the color light of patterns can be influenced by the color light of a bottom color to cause color change or color withering, for example, flowers with middle and dark bottom colors or light-colored thin points or lines with fine requirements for the dark bottom color, and meanwhile, the condition of multiple colors is avoided, and the self-connection printing of the coating is useless, so that the requirements of customer products are difficult to meet. Later discharge printing and resist printing can solve the problems to a certain extent, but the two printing technologies have long process routes, difficult control of the process and poor process reproducibility.
In order to solve the above problems, paint overprinting attracts attention as a special printing technology, and the main difference from ordinary paint printing is that inorganic pigment is added into paint overprint color paste or the use amount of the inorganic pigment is increased, and high-concentration paint is used for improving the covering power of ground color. The hiding power of paint is generally that a uniform paint film is scraped on the surface of a fabric, so that the surface of the fabric presents another color, and the original surface color of the fabric is hidden, and simultaneously, the fabric is given various colors as required. This ability of the paint to make the fabric's background color impervious to the paint film is referred to as the hiding power of the paint.
