Early, propylene polymerization can only get low degree of paper-based products, a non-crystalline compounds, no practical value. In 1954, Ziegler and Natta invented Ziergler-Natta catalysts and formed a crystalline polypropylene having a high stereoregularity, called isotactic polypropylene or isotactic polypropylene. The findings open up a new direction in the art of polymerization, to large-scale industrial production of polypropylene and is widely used in plastics and fiber production laid the foundation.

1957, by the Italian company Montecatini first realized industrial production of polypropylene. 1958-1960, the company will for the polypropylene fiber production, development of polypropylene fiber tradename Meraklon, after the United States and Canada have also started production.

After 1964, he has developed a polypropylene film split fiber bundling of films by fibrillation carpet made of textile fibers and yarns, and other products.

In the 1970s, short-spinning technology and equipment to improve the production process of polypropylene fibers. Over the same period, bulked continuous filament carpet industry began to be used. Currently, 90% of the carpet backing and 25% carpet veil made from polypropylene fibers.

After 1980, with the development and manufacture of polypropylene, polypropylene fibers of new technologies, in particular metallocene catalysts of the present invention makes the quality of the polypropylene resin has been significantly improved. Due to increasing its stereoregularity (isotacticity 99.5%), thus greatly improving the intrinsic quality of the polypropylene fibers. The mid-1980s, especially fine polypropylene fiber replace some of the cotton fibers, used in textile fabrics and nonwovens. Plus the emergence of developing one-step BCF spinning machine, air texturing machines and composite spinning machine as well as non-woven fabric and the rapid development of polypropylene fiber in terms of decorative and industrial purposes to further expand. In addition, the world of polypropylene fiber research and development is quite active, differentiated fiber production technology popularization and improvement, greatly expanded the application field of polypropylene fibers.
