Material Choices

Nylon: This man-made fiber provides a less expensive option than all-wool or silk versions. Karastan incorporates “Eversoft Nylon” in our Studio Collection. In addition, we use high-twist nylon in the luscious Aria Collection in combination with wool for an unusual effect. Look for an 80/20 wool-nylon blend in our handsome Vintage Road rugs as well.

Polypropylene: Polypropylene is a thermoplastic resin made from propylene gas. Rugs made of polypropylene are often heat-set to minimize luster and improve softness.

This is the most expensive rug fiber and even the smallest addition to the content can raise the price. It is also a natural fiber and adds high luster to the end product. Visit our Persian Renaissance collection for fine examples of silk used as accents. These rugs beautifully illustrate the dramatic effect silk adds to the design.Polyester has good color clarity, colorfastness, and resistance to water-soluble stains. All of Karastan’s staple polyester yarn comes from the company’s state-of-the art plastic bottle recycling facility. This “food” grade PET Polyester fiber might be considered to be better quality than “carpet-grade” polyester fiber. 

Viscose: Viscose is a shiny, silk-like fiber made from wood pulp. On its own, Viscose is susceptible to matting, but when used as an accent or in a blend, Viscose makes a wonderful substitute for higher-priced silk.

Wool: The most beautiful and luxurious choice of all, 100 percent New Zealand worsted wool is used in most Karastan rugs. Wool is a natural fiber that is highly regarded for its strength, durability, crush resistance, cleanability, comfort, and beauty. Visit Karastan Wools to learn more about this superior fiber.
