Which fiber is commonly used in high-end carpets for its luster and softness?

Wool is often chosen for high-end carpets due to its natural luster and exceptional softness. This luxurious fiber has a unique structure that reflects light beautifully, giving wool carpets a rich, radiant appearance. Furthermore, wool is highly resilient and can recover its shape and texture after being compressed, making it ideal for areas with heavy foot traffic. Its natural properties also allow it to be more stain-resistant compared to synthetic fibers, which adds to its appeal for premium carpet options.

In contrast, while cotton is soft and relatively easy to dye, it does not have the same resilience and can absorb moisture, making it less suitable for high-traffic areas. Sisal, a natural fiber derived from plants, is durable but lacks the softness and luxurious feel associated with high-end carpeting. Nylon, though popular for its strength and stain resistance, does not match the luxurious quality that wool embodies. Thus, wool stands out as the preferred choice for those seeking upscale, soft, and lustrous carpet options.
