Leather machinery and equipment have been favored by everyone for several years, but leather has been seen in brown and black since ancient times. With the advent of warm winter, the provisions on leather fashion are more prominent. The sales market has greater and greater requirements for leather post-processing goods such as leather printing, and the continuous development of professional skills in today's printing and dyeing industry, It also provides professional skills for the production and manufacture of strange printed leather.
Leather machinery configuration
Leather comes from small animals, which determines the irregularity of leather. In addition, the leather cost is high and can not be consumed, so it is decided that the leather printing configuration can not be mechanically copied from the printing configuration of textile products. Today, the printing configuration in the leather industry is divided into immediate printing configuration, transfer printing configuration and some support configuration. Immediate printing configuration: although it is hand-made lifting plate, it has the advantages of fast pattern transformation, wide peripheral resistance, convenient overprint and so on. However, the higher problem of handmade lifting plate for leather printing is that it consumes a lot due to the irregularity of leather. The professional term is paste edge. Finally, it needs to be repaired with scissors. Therefore, there are not many handmade lifting plates for leather printing.
Recently, the roller printing machine is popular for leather printing. The printing results of the special roller printing machine developed by Han can print wanton and exquisite pattern design, and the utilization rate of leather machinery can be guaranteed without consumption at all. Others, there are drip molding machine and embossing machine. Transfer printing configuration: transfer printing requires a paper printer and heat transfer equipment. Nowadays, foreign countries use plastic film to replace printing paper, so a plastic film printing equipment can also be used. Support configuration: support configuration is an important configuration of leather printing factory, which is related to product variety and sales market share.
Leather printing process
First, although it is dye printing, the higher benefit of dye printing is that the touch is not affected. However, leather can not be heat-resistant steaming, so the processing technology can not be mechanically applied to textile products. There are a series of dyes in foreign countries. Anxiety is a 1:2 metal material complexation dye. There is no need to steam it to print the skin. It can be dried in the air. However, this kind of dye has high cost and its strength is only 30% to 50% of that of ordinary dyes. It is very poor when encountering dark and dense colors. It is guessed from the printing and dyeing of textile products that a series of dyes are selected. The color fastness is very similar to that of imported ones, and the color tone is beautiful and the strength is high. Only the light fastness is slightly weak. It can be printed on the leather equipment for drying, with excess steaming and water cleaning.
The second is the architectural pigment printing of leather machinery and equipment, which is a higher type of printing in leather printing. Because architectural paint printing can express gold, white and silver, coupled with hot film, the commodity is also a cross platform transformation, which can express the noble and beautiful characteristics of leather to a greater extent. Wear resistant electrode. Transfer printing: transfer printing is a key printing point of appropriate leather, which is divided into dry and wet according to the processing technology. Dry migration is mostly made of hot sol into printing ink, printed on double-sided tape or BOPP film, and then migrated on leather under compression standard. Wet migration is to spray a special aqueous solution on the leather first. Then press it to dissolve the dye on the migration paper with the aqueous solution, and then contact it on the leather.
