The main factors affecting printing drying temperature and time: With the drying temperature, the product to improve the wet rubbing fastness, fastness of the adhesive film has been improved. Leather with drying shrinkage rate increased with the increase of temperature and time. Pigment paste with a binder ratio: less binder in the printing paste, the membrane integrity of a poor coating of the solid pigment particles is poor, resulting in printing the product after drying the wet rubbing fastness is low. Also, because the printing paste adhesives less, resulting in high solid content printing paste, paste the stability of the poor, vulnerable layered, easy storage, while the binder content is too high, to improve the effect of wet rubbing fastness products not very clear, and will affect the feel, while also increasing the cost of production. Therefore, controlling the ratio of the pigment paste and the adhesive wet fastness of the leather has a great influence. Additives: additives are added in order to adjust the viscosity of the slurry, to improve the feel and appearance of the product. However, the coverage of the pigment is too much decreased, the color faded, the control with the ratio of the pigment is particularly important to improve the dyeing effect. Other: pigments crystalline state, particle size and its distribution on the leather color, brightness, color fastness, etc. have a great impact on application performance.
