SmartStrand Structure with DuPont Sorona

SmartStrand is made from renewable resources for the environmentally conscious. This revolutionary carpet has built-in stain protection, superior durability and surprising softness. Smartstrand is the work of the two strong consumer brands with a history of innovation. When Karastan and Dupont combine their knowledge they create unmatched quality with an environmental impact.

Nylon fibers usually have only the outer layers of the carpet fibers covered with stain protection that can rub or wear off over time. SmartStrand with DuPont Sorona provides built-in stain protection throughout the entire strand of carpet fiber. SmartStrand is certainly helping Karastan to meet its sustainable goals. For example, for every seven yards of SmartStrand, enough energy is saved to equal one gallon of gasoline; the production of the Sorona polymer requires 30 percent less energy than an equal amount of nylon 6, the fiber found in many conventional carpets; and SmartStrand carpets are CRI Green Label Plus certified for low emissions.


SmartStrand is made up of renewable ingredients to replace delicate natural resources. Here is the process that each roll of SmartStrand Carpet goes through.

Corn is planted and grown in fields across America.

Fully matured corn is harvested and sent to Loudon, TN.

The sugar from the corn is processed and the end product (Bio-PDO)TM becomes a key ingredient in DuPontTM Sorona® renewably sourced polymer.

DuPont Sorona is spun into fiber by Karastan and then turned into SmartStrand® carpet
