Description

technical field

[0001] The invention belongs to the technical field of leather dyeing equipment, and relates to a leather dyeing machine. Background technique

[0002] Leather dyeing is a complex physical and chemical process, which is the process of penetration and bonding of dye molecules to leather fibers, and is the total effect of physical and chemical effects. During the whole dyeing process, adsorption, diffusion, penetration and fixation interact and alternate with each other. The leather dyeing process involves a wide range of factors, and there are many influencing factors, which can be mainly divided into factors such as equipment, dyeing materials, technology and operation. Although with the continuous development of production and the continuous improvement of scientific and technological level, dyeing machinery is also becoming more and more advanced, but the quality problems caused by equipment cannot be completely avoided.
