Solvent-free polyurethane automobile leather manufacturing method

Abstract

The invention relates to a solvent-free polyurethane automobile leather manufacturing method. The solvent-free polyurethane automobile leather manufacturing method comprises bottom rack, a vertical rack, a tensioning mechanism, a winding mechanism, a printing mechanism and a cleaning mechanism. According to the solvent-free polyurethane automobile leather manufacturing method, in the automobile leather printing manufacturing process, the difficult problems that a, in the traditional leather printing manufacturing process, as leather is in a loose state in the machining process due to the lackof a tensioning device, the printing effect is poor, pattern lines may be blurred and the use effect is affected due to the loose leather when the leather is machined; and b, in the traditional leather printing manufacturing process, due to the fact that one device only corresponds to one pattern line, the printing effect is single, the diversity of printing cannot be realized, and meanwhile, thesurface of the printed leather cannot be cleaned, so that impurities exist on the surface of the machined leather, and the quality of the leather is influenced.

Description

technical field [0001] The invention relates to the field of automobile leather manufacture, in particular to a method for manufacturing solvent-free polyurethane automobile leather. Background technique [0002] As an important part of automobile interior, automobile leather plays an indispensable role in the process of modern automobile processing. Traditional automobile interior generally uses cotton cloth type materials, which may have disadvantages such as easy to get dirty and difficult to disassemble and wash. Compared with cotton cloth type materials, leather materials are not easy to get dirty. Even if dirt is attached to the leather surface, the surface can be wiped with cleaning agent and rag to achieve the decontamination effect. At the same time, for The aesthetic effect of car interiors can be printed on car leather. [0003] At present, there are the following problems in the printing manufacturing process of automobile leather: a. In the traditional leather ...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a solvent-free polyurethane automobile leather manufacturing method, which can solve the following problems in the printing manufacturing process of automobile leather: a. In the traditional leather printing manufacturing process, the leather is in a slack state during processing due to the lack of a tensioning device , when the leather is processed, the printing effect is not good due to the relaxation of the leather, and the pattern texture may appear blurred, which affects the use effect. b In the traditional leather printing manufacturing process, because one device only corresponds to one pattern pattern, the printing effect is caused. Single, can not achieve the diversity of printing, and can not clean the surface of the leather after printing, resulting in impurities on the surface of the leather after processing, affecting the quality of the leather
