The invention discloses a fourdrinier forming online spun-bonded spunlace composite non-woven fabric. The fourdrinier forming online spun-bonded spunlace composite non-woven fabric comprises an online wet-process fourdrinier forming first fiber layer and an online spun-bonding net forming second fiber layer, and is formed by laminating and spun-lacing the first fiber layer and the second fiber layer. The non-woven fabric can be prepared only through synchronous one-time forming of online fourdrinier forming and online spun-bonding in the production process, the process is simple and convenient, the relatively high production speed of 400-1200 m/min can be achieved through fourdrinier forming and spun-bonding forming, and the limit that the highest production line speed of an existing PP spunbonded composite wood pulp spunlace non-woven fabric production line is 160 m/min can be broken through; the production line coiling line speed of the fourdrinier forming online spun-bonded spunlace composite non-woven fab
