The invention provides a manufacturing method of high-physical-property
embossing dry-method environment-friendly sofa leather. The manufacturing method includes the steps that 1, sofa leather base fabric including base fabric A and base fabric B is prepared; 2, the base fabric A is attached to the base fabric B through
adhesive resin, the base fabric A is arranged on the base fabric B, microspheres foaming
powder is added to the
adhesive resin, and the composite base fabric is obtained after
drying and foaming are conducted; 3, a piece of release paper is coated with a surface-layer
sizing agent and then dried; 4, the release paper is coated with a middle-layer
sizing agent and dried; 5, after the release paper is coated with bonding-layer resin, the composite base fabric is attached to the release paper, and the release paper is stripped after
drying is conducted; 6,
embossing and posttreatment are conducted, and a finished product is obtained. According to the method, base fabric of different knitting tightness is attached to one another through the
adhesive resin, a tissue structure which is similar to natural leather and has a
density gradient is obtained, and a product is high in genuine leather feeling; the excellent
embossing property is obtained through the high-temperature molten deformation functions of a microspheres foaming layer, an adhesive layer and a dry-method layer; a wet-method
coating is not used,
hydrolysis resistance is improved, and residues of DMF are lowered.
