Abstract: The present application relates to a polypropylene with high melt flow index and a method for producing the same, and meltblown fiber fabrics. A reacting mixture is firstly provided, and a polymerization process is performed to the reacting mixture in a slurry reaction system to obtain the polypropylene. The reacting mixture includes propylene monomers, Ziegler-Natta catalysts, organoaluminum compounds and electron donor. The polypropylene has high melt flow index and adjustable melting point and molecular weight distribution, such that it is used to produce the meltblown fiber fabrics.
