Pearlescent printing process
The pearl printing process refers to the process of mixing pearl-like materials with film-forming agents, cross-linking agents, emulsifiers, and colorants to print on fabrics. Pearl pigment printing raw materials Pearl pigments are divided into natural and non-natural. Natural printing raw materials are mainly composed of pearls and fish scales. The surface of these raw materials has a very glossy and anti-finish effect, and is particularly suitable for pearl pigments. However, due to These raw materials have poor stability and poor fastness after fabric printing. Moreover, the quality of raw materials varies, the output is small, and the price is expensive. It is difficult to meet the market demand for bead-finished printing on fabrics. Non-natural beaded pigments refer to artificially prepared raw materials, also called artificial beaded pigments. Artificial beaded pigments are developed from mica ores and are called mica core-coated metal oxides. This metal oxide has high strength, It has the characteristics of heat resistance, sulfur resistance, shear resistance, etc., and the fabrics printed with this pigment not only have a pearl-like luster, but also have the charming color of transparent slurry. Printing glue constitutes the bead-finished printing glue. In addition to the bead-finished pigment, it also needs a mixture and a thickener. The effect of the A mixture is good transparency and firm film formation, while the thickener forms a film on the surface of the fabric. Three The bead-finished printing glue can be formed by mixing and blending. As a high-value-added fabric printing glue, bead-finished printing glue is required to be colorless and transparent after film formation, with a refractive index similar to that of glass. Only in this way can the bead-finishing effect be good.
