What fiber smells like asphalt or paraffin when burnt?

The correct choice is olefin, which is also known as polypropylene. When olefin fibers are burned, they emit a distinct odor reminiscent of asphalt or paraffin. This is a characteristic that helps to distinguish olefin from other fibers.

Olefin is a synthetic fiber known for its resilience and resistance to stains and moisture, making it popular in carpet manufacturing, particularly in indoor and outdoor applications. Understanding the burning characteristics and associated odors of various fibers is important for professional carpet cleaning technicians, as it aids in accurate identification and proper care during cleaning processes.

Other fibers, such as cotton, nylon, and acrylic, have their own unique burning smells. Cotton tends to smell like burning paper, nylon releases a smell similar to that of burning hair, and acrylic fibers can emit a sweet odor. Familiarity with these characteristics assists technicians in identifying materials and applying appropriate cleaning methods, ensuring the best care for different types of carpets.
