China's fiber-grade polypropylene resin is far different from foreign advanced countries in terms of type and quantity, and it is far from meeting the demand of polypropylene fiber raw materials in the domestic market, which hinders the development and application of polypropylene industry in China. In order to adapt to polypropylene fiber, especially the non-woven fabrics and high-grade polypropylene fibers (polypropylene superfine denier, meltblown non-woven fabrics, etc.) market demand for rapid growth.
 
In the world, the use of polypropylene filament yarn in the garment industry began in the 1970s, but it has not been widely used in the past 20 years. One of the main reasons is that the monofilament is too thick, making the polypropylene fabric feel hard. Wax is strong, uncomfortable to wear, and easy to pilling, so it is not recognized by consumers. With the development of the world chemical fiber industry, in the late 1980s, people improved the spinning polypropylene sheet and perfected the spinning technology. On the basis of the fine denier, polypropylene ultra-fine denier. The performance of polypropylene filament yarn has produced a qualitative leap, thus opening up a new era of polypropylene filament yarn for apparel fabrics.
