Polypropylene filament is a very common carpet yarn. Polypropylene fiber can also be called polypropylene fiber. Polypropylene fiber is not like other types of carpet fibers. Polypropylene itself is non-absorbent and has low dyeing performance. Therefore, in the process of dyeing the raw silk, the color has actually been built and becomes a part of the carpet. Even if exposed to strong sunlight, bleach, air pollution or other harmful substances, it will not fade.

This kind of characteristic wool yarn and polyester can also be substituted. For example, wool yarn is soft in texture, has strong durability, and is easy to clean. However, wool yarn is prone to static electricity and is difficult to maintain. Polyester yarn is the most popular fiber for consumers. Because polyester is the first to be marketed and has superior performance, it has the highest acceptance. Polypropylene BCF yarn not only has the characteristics of conventional polypropylene, such as low density and high strength, the yarn fabric covers a large area. The fabric made of polypropylene BCF yarn has a soft and comfortable texture, has the feel of wool, and is more warm. In the dyeing process, the original solution is used for dyeing and antibacterial agents are added. After a series of processing, the polypropylene filament is not easy to fade, and it also has the effect of antibacterial and anti-odor, which is rare in yarn types.
