▎ 摘　　要

NOVELTY - Bio-based degradable impregnated knitted fabric polyurethane synthetic leather veneer product, comprises base fabric of synthetic leather veneer, which is a cotton-polyester blended knitted fabric; and the synthetic leather veneer finished product is obtained by (1) pre-impregnating the base fabric, and pre-impregnated materials include bio-based degradable polyurethane resin, dimethylformamide and ultra-fine graphene, (2) coating on the pre-impregnated base cloth, and coating material includes bio-based degradable polyurethane resin, (3) solidifying biodegradable polyurethane resin on the surface of the base cloth, (4) washing the base cloth with clean water, and Dimethylformamide on the base cloth, (5) preheating, ironing, drying and shaping base fabric to obtain the bottom embryo, and (6) applying the solvent-based biodegradable polyurethane resin to release paper, placing the release paper into oven to heat to form a film, and attaching the film to bottom embryo, and drying. USE - The bio-degradable and dip-coated and coated polyurethane synthetic leather surface finished product for shoe manufacturing, furniture manufacturing and luggage manufacturing. ADVANTAGE - The bio-degradable and dip-coated and coated and coated polyurethane synthetic leather surface finished product does not cause pollution to the surrounding environment and prevent the harm to the health of the personnel.
