Description

Technical Field

[0001] The utility model relates to the technical field of wet processing of synthetic leather, in particular to a base cloth input pre-treatment device for wet processing of synthetic leather. Background Art

[0002] Wet processing of synthetic leather is a technology for producing synthetic leather. The basic principle of wet processing is to de-bubble a mixed solution containing polyurethane wet resin (usually containing DMF solvent and other fillers and additives) through a vacuum machine, then impregnate or coat it on a base cloth, and then put it into water with affinity for the solvent. The solvent is replaced by water, and the polyurethane resin gradually solidifies to form a porous film, that is, a microporous polyurethane particle surface layer. The semi-finished leather formed in this process is called base.

[0003] Before the wet processing of synthetic leather, dust is easily adhered to the upper and lower surfaces of the synthetic leather base cloth. Direct processing is likely to contaminate the processing mixed solution. Moreover, there are wrinkles on the surface of the synthetic leather base cloth, which are also likely to reduce the quality of the synthetic leather during the processing. Content of the Utility Model
