Abstract

The invention relates to a leather printing product and a preparation method thereof. The preparation method comprises the following steps of (1) selecting finished leather (cowhide, sheepskin, pigskin or horse skin) for surface pretreatment to obtain pretreated leather; (2) preparing water-based color paste, and printing the water-based color paste on the surface of the pretreated leather to obtain printed leather; and (3) enabling the printed leather to be dried and then subjected to color fixation treatment, and obtaining the leather printed product after color fixation treatment is completed. The preparation method solves the existing problems that leather printing fades and is not resistant to dry and wet rubbing, a printing material is not environmentally friendly, a printed finished product is poor in hand feeling, the breathability of leather is affected, the printing material is high in cost, and printing paste is likely to crack due to long-time use. And the quality of the leather printed leather finished product can be effectively improved, so that the leather product is more colorful and has fashionable design.

Description

Technical field [0001] The present invention belongs to the field of leather, and is specifically related to a leather printing and a preparation method thereof. Background technique [0002] The dermis is mainly composed of connective tissue such as collagen fibers, elastic fibers, mesh fibers, and amorphous matrices. Therefore, the dermis has natural and smooth surfaces and comfortable breathable, texture delicate, full, and feel flexible. This is also the advantage compared to artificial leather. In recent years, with the improvement of people's living standards, the quality and personalization requirements of matter are also increasingly high. The existing leather products are subject to color single, and innovation is gradually far from the vision. Although people have worked hard to study a variety of leather printed methods, most printing methods have different defects and problems, and even some techniques cannot be applied to printing of leather products. [0003] Specif...
