Leather, thousands of years has been the love for the people, but has always been the brown leather, black entertainment, with the arrival of warm winters, the requirements of fashion leather increasingly prominent, the demand for processing Leather, leather and printing needs Yulai larger, modern textile industry continues to technical progress, but also for the production of printed leather strange provided technical support. 1. Printing equipment leather, leather comes from animals, which determines the irregularity of the skin. Along with the high price of leather, not be wasted, so I decided not to copy the textile, leather, printing equipment printing equipment. Currently the leather sub-sector direct-printing equipment printing equipment, printing equipment transfer, and auxiliary equipment. a. Direct Printing Equipment: hand-carried aboard the choice, of course, has a pattern of rapid change, adaptability, color and easy. However, the hand plate transport to print leather, the biggest problem is due to the irregularity of the skin caused a lot of waste, called pulp art technical terms, the last to use scissors to repair, so that the hand-carried to the printing plate in the leather not much. Not before that leather is the most common printing roller printing machine, developed by the Korean leather special roller machine printer with excellent print results, can print fine patterns can be done to maximize the use of leather , little or no waste. Moreover, the machine fall plastic stamping machine. b. transfer printing equipment: transfer printing to a printing machine and the heat transfer machine, now on the outside with the film instead of paper, so that the printer can also be a film. Heat transfer machine is different from textiles, and requires pressure, normal operating pressure of 20 ~ 30kg/cm2, usually oil. The temperature is less demanding, more than 120 degrees, 80 degrees is quite common. c. Auxiliary: Auxiliary machinery is the key equipment of the printing plant of leather, which was related to the product range, market share. 2. Printing skin of a process. The first is the printing ink, printing ink of the biggest advantages is that touch is not affected. But leather is not high temperature steam, so you can not copy the textile process. Abroad range of dyes, dyes metal complex type mainly 1:02, is used to print the leather is not steaming and drying may be, but the high price of these dyes, dye strength was only 30% of normal in 50%, Shennong are annoying color. Textile printing dye selected from a series of robustness of the coloring matter is considerable, and bright colors, high power points, light fastness is only slightly worse, can be printed on the leather to dry, without steam cleaning. b. followed by print printing leather, in the amount of which is the largest class of printing. Since the printing of gold and silver pigment can be expressed, along with the hot film, the product is constantly changing, the ultimate expression of the skin features noble, beautiful. C. Transfer electrode wear printing: printing transfer skin is the most appropriate way of a seal, according to sub-humid techniques, two ways. Dry transfers, many are made with hot melt ink, printed BOPP release paper or film, hot conditions and then transferred to the leather. Transfer wet spray a special solution, and leather. Then hot, so that the dye transfer paper dissolved and the solution, and then fixed in the leather. Transfer printing, leather, is currently the method of printing high quality leather for a class, the master of detail, visual effects, not as comparable. Currently there are factory specializing in the production of paper, such transfers abroad, the price of 40 to 50 yuan / m.
