Method for making synthetic leather |
摘要 |
A method for making synthetic leather includes the steps of: preparing a knitted substrate having a longitudinal direction and a transverse direction transverse to the longitudinal direction, the knitted substrate being stretchable in the longitudinal and transverse directions; positioning two opposite sides of the knitted substrate along the longitudinal direction respectively on two conveyer chains and advancing the knitted substrate without tensioning the substrate along the longitudinal direction; and forming a coating on the knitted substrate by applying a polyurethane solution on the knitted substrate.
