The invention relates to a spunlace micro-fiber composite non-woven fabric and a manufacturing method thereof. The spunlace micro-fiber composite non-woven fabric comprises a spunlace micro-fiber non-woven fabric layer and a spunlace non-woven base fabric layer, tensile strips are arranged in the spunlace non-woven base fabric layer, and the spunlace micro-fiber non-woven fabric layer and the spunlace non-woven base fabric layer are connected in a spunlace and combined manner. The spunlace micro-fiber composite non-woven fabric solves the problem that a single superfine fiber non-woven fabricis nonuniform in density, density uniformity and compactness are improved, and the non-woven fabric is high in elasticity, good in tensile strength, rich and fine in hand feeling and can be widely used for high-grade imitation leather base fabrics, high-grade home textile bed sheets, quilt covers and the like.
