Abstract: A method of making artificial leather includes: applying on a fabric substrate a coating layer that includes a mixture of a resin and a gas bubble material; and heating the fabric substrate and the coating layer until the gas bubble material bursts and breaks the coating layer to open and form hairy filaments. A semi-product includes the fabric substrate, and the coating layer disposed on the fabric substrate. The coating layer includes a mixture of the resin and the gas bubble material that is burstable under heat to cause the coating layer to break into hairy filaments.

Abstract: 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.
