Guangdong Mengtai Textile Fiber Co., Ltd. specializes in the research and development of polypropylene fine denier, polypropylene profiled yarn, polypropylene FDY network yarn, and polypropylene FDY yarn. The silk produced is widely used, and it is widely used in many industries such as high-grade bag fabrics, thermal fabrics, environmental fabrics, and home textile fabrics.


Polypropylene profiled yarn came into being. Popularly speaking, profiled polypropylene is polypropylene filament yarn with various shapes such as stars, triangles and polygons. The production process is to produce polypropylene profiled yarns by making cross-sections of different shapes of spinning holes. .


The different cross-sections of polypropylene filaments not only affect the feel and shape of the fabric, but also affect the volume, elasticity, gloss, wicking effectiveness, insulation, gloss processing properties, and dirt absorption effects of the fabric, for example, circular cross-sections. The polypropylene filaments magnify the dirt adsorbed on the surface, while the polygonal polypropylene filaments can effectively interfere with this effect.


From this we can find that the biggest difference between polypropylene profiled yarns and common polypropylene yarns lies in the cross-sectional shape. Because of the different cross-sectional shapes, polypropylene profiled yarns have some unique properties.
