Wool
A natural fiber produced from the fleece of sheep. Noted for its inherent ability to resist stains, repel moisture, and retain appearance, wool is the most commonly used fiber found in handmade rugs.
Semi-Worsted Wool
An extra step implemented in wool processing that combs out shorter fibers, collecting only the longer, more durable and lustrous wool. This process results in a finer quality fiber used in high quality rugs.
Silk
A natural fiber processed from silk worm cocoons, silk is often used to accent rug designs. It is a delicate fiber that has a luminous natural sheen and takes color beautifully.
Polypropylene or Olefin
Petroleum based products, derived from propylene and ethylene gasses. The polypropylene fiber is characterized by its resistance to moisture. It is strong, abrasion resistant, quick drying, colorfast, mildew resistant and soil and stain resistant. Its fibers have the lowest density of all manufactured fibers giving olefin textiles a very lightweight quality.
Nylon
A durable, petroleum based synthetic fiber that is resistant to soil and is easily cleaned. Nylon also has good dyeing characteristics. Nylon yarns can be solution dyed, skein dyed and/or space dyed.
Viscose
Either present as a synthetic fiber typically made from viscose/rayon, or a natural fiber using mercerized cotton. Also called "faux silk," viscose is usually used as small accents or in a short, dense pile construction to add a shimmering effect.
Sisal/Jute
A natural plant fiber that is strong, easily stained, and not recommended for use in areas with moisture.
