Abstract

The invention discloses a preparation method of printed synthetic leather. The printed synthetic leather is prepared by a non-woven fabric warp direction directional elongation and high-temperature sizing step, a wet process warp direction directional elongation and high-temperature sizing step, a dry method face making step and a plate printing step using at least two colors of printing ink. Compared with the prior art, the defects such as the poor printing color fastness, low production efficiency, high cost and the like of the synthetic leather can be overcome; and the prepared printed synthetic leather has rich apparent flower color and patterns, and can be produced in a large scale.

Description

technical field [0001] The invention relates to a printing method for synthetic leather. Background technique [0002] Usually, the process of transferring the graphic information on the original manuscript to the substrate, and making the dye or pigment form a pattern on the substrate is printing. Printing is partial coloring, which requires a certain color fastness. The printing of two or more colors on the substrate is called register printing. After register printing, regular and multi-color patterns are formed on the substrate. [0003] Process printing has become very common in paper printing such as newspapers and advertisements, clothing fabric printing and plastic packaging materials. The printing methods can be divided into gravure printing, letterpress printing, screen printing, lithographic printing, flexo Thermal transfer printing, etc.; monochrome printing is also widely used in synthetic leather, and gravure and letterpress printing are mostly used. [0004...
