Abstract

The invention provides a preparation technology of printed base cloth synthetic leather with high transparency. The preparation technology comprises steps as follows: fabric base cloth is prepared firstly and coated with a transparent base layer, and then the transparent base layer is subjected to printing operation with special transparent printing paste, therefore, high transparency and excellent printing effect of the prepared synthetic leather can be guaranteed; besides, by means of strict control for setting temperature and setting time of the fabric base cloth, components and ratio of the components of the transparent printing paste as well as three-section color fixation treatment after printing, sufficient interaction of the components can be guaranteed, the synergistic interaction effect is achieved, excellent printing effect and transparency can be guaranteed while excellent base performance of the fabric base layer is guaranteed, the effects of air and moisture permeability, visual clarity and the like can be achieved, and the fabric has excellent glossiness.

Description

technical field [0001] The invention relates to the field of synthetic leather, in particular to a preparation process of high-transparency printed base cloth synthetic leather. Background technique [0002] At present, synthetic leather products have gradually become a popular trend in the future. Synthetic leather has been widely used in the production of luggage, clothing, footwear, furniture and other products. But at the same time, with the development of social economy and the improvement of people's living standards, the requirements for the added value of these daily necessities are also getting higher and higher. At present, the processes with high transparency effect include moisture curing and secondary veneer processes. Moisture-curing products are prone to fogging, darkening of gloss, and intolerance to yellowing; while products with secondary veneering technology can solve such problems, but the cost is too high and the production operation is difficult. Con...
