What is another name for polypropylene fibers?

Polypropylene fibers are commonly referred to as "olefin." This term highlights the chemical family of the fibers, which is derived from olefins in the polymerization process. Olefin is a significant category in the textile industry, known for its durability, resistance to moisture, and stain-hiding capabilities, making polypropylene a popular choice for upholstery and various fabric applications.

The other terms listed, such as polyester, nylon, and acrylic, refer to different types of synthetic fibers with distinct chemical compositions and properties. Polyester is derived from polyethylene terephthalate, nylon is a polyamide, and acrylic is made from polyacrylonitrile. Each of these fibers has unique characteristics suited to specific uses, but they do not apply to polypropylene, which is why they are not synonymous with it.
