The utility model discloses a
microfiber synthetic leather air permeability modifying device, and particularly relates to the technical field of synthetic leather production, the
microfiber synthetic leather air permeability modifying device comprises a
milling cutter head, a
machine body, a synthetic leather
polishing assembly and a dye
pool, a feed port is formed in the center of the left side of the
machine body, a
discharge port is formed in the center of the right side of the
machine body, and the synthetic leather
polishing assembly is arranged on the right side of a guide roller; the dye
pool is arranged on the right side of the body inner cavity; the synthetic leather
polishing assembly is used for polishing the two faces of the
microfiber synthetic leather, the
fiber structure of the microfiber synthetic leather is strengthened, gaps among fibers are increased, air circulation is promoted, the
surface structure of the microfiber synthetic leather is more uniform,
dirt and impurities on the surface of the leather are removed, the surface becomes smoother, the
dyeing process is more uniform, and the quality of the microfiber synthetic leather is improved. The surface of the synthetic leather is coated with the
cleaning agent, the pore openness of the surface of the synthetic leather is increased, the adsorption performance of dye is improved, adsorption and attachment of a
dyeing coating are facilitated, a good foundation is provided for subsequent
dyeing work, and dust attached to the surface of the synthetic leather is removed through the ultra-long
brush.
