Suining Tongjia New Materials Co., Ltd. (formerly Suining County Tongjia Chemical Fiber Plant) has been focusing on the research and development and production of polypropylene fiber materials since its establishment in 2014. The company's products cover high-strength polypropylene filaments (heavy industrial filaments) ranging from 250D to 6000D, engineering fiber filaments, colored filaments, network filaments, flame-retardant filaments, and twisted filaments.

With its high strength, low shrinkage, flame retardancy, weather resistance, and excellent thermal stability, high-strength polypropylene filaments are widely used in various applications such as wool tops, hoses, webbing, water hoses, geotextiles, industrial fabrics, and filter cloths. The company's products have a breaking strength of 6.5-7.0 g/d and excellent resistance to acid and alkali corrosion and UV aging, making them well-suited for outdoor operations and various environmental conditions. Furthermore, the company supports customized production of shaped cross-section filaments, flame-retardant reinforced filaments, and colored spun filaments, helping customers reduce production losses and improve the yield of finished products.
