What is a key feature of olefin fiber?

Olefin fiber, also known as polypropylene, is recognized for its lightweight nature and excellent stain resistance. This makes it a popular choice in residential interior design, particularly for upholstery and carpets. Its lightweight characteristic ensures ease of handling, installation, and cleaning, while the stain resistance provides practical benefits in maintaining the appearance of fabrics in high-traffic areas.

In contrast, the other options do not accurately describe olefin fiber's characteristics. For example, olefin does not retain moisture well; instead, it is hydrophobic, meaning it repels moisture. This property contributes to its quick drying capability. Additionally, while olefin is a synthetic fiber and not derived from plant sources, it is entirely made from petrochemicals. Lastly, while the sustainability of fibers can vary, olefin is generally not characterized specifically as a sustainable fiber compared to natural fibers, which may be more environmentally friendly. This distinction highlights why the lightweight and stain-resistant features of olefin are pivotal attributes in its use.
