Lightweight: Polypropylene is one of the least dense synthetic fibers, and polypropylene bulked yarn similarly features lightweight properties, making products manufactured from it easy to carry and use. For instance, in fields such as outdoor gear and sports equipment, the lightweight characteristic of polypropylene bulked yarn is highly favored.

Chemical Stability: Polypropylene exhibits excellent chemical stability, demonstrating strong resistance to acids, alkalis, and other chemical substances. Polypropylene bulked yarn is unlikely to undergo chemical reactions in general chemical environments, maintaining stable performance. This makes it suitable for applications requiring high chemical stability, such as filtration materials in industries like chemical engineering and pharmaceuticals.
