What are the end use markets where Sorona® is used?
Answer: Sorona® is primarily sold in fiber applications including apparel, residential carpets & rugs, commercial carpets, as well as automotive carpets, mats and interiors.
What are the performance attributes and benefits of Sorona® in carpeting?
Answer: Carpeting made with Sorona® offers durability — equal or better than leading nylon carpeting, crush resistance and resilience. In addition, carpeting made with Sorona® is permanently and naturally stain resistant — the stain resistance is built into the fibers so it won’t wash or wear off like topical treatments can. Typical stains including coffee, juice, red wine, etc. will not stain carpet made with Sorona®. Even chlorine bleach will not damage or take the color out of carpeting made with Sorona®.

What are the environmental benefits of Sorona®?
Answer: Sorona® has a three-pronged environmental story. The production of Sorona® uses up to 30% less energy than the production of an equal amount of nylon 6. Second — the production of Sorona® reduces greenhouse gas emissions up to 63% over the production of an equal amount of nylon 6. And Sorona® helps reduce our dependency on oil and petrochemicals by using ingredients made from annually renewable resources. Sorona® contains 37% renewably sourced ingredients by weight.

If Sorona® is 37% renewably sourced by weight, what’s the other 67% made with?
Answer: The other principal ingredient (monomer) is currently made with petroleum based ingredients.
What is the renewable resource used to make Sorona®?
Answer: Sorona® is a polymer (poly meaning more than one) made from two main ingredients. One key ingredient, Bio-PDO™ (bio-based 1,3 propanediol) is made through a fermentation process that uses glucose as the feedstock. Right now, sugar extracted from feed corn is used.
Is Sorona® recyclable?
Answer: DuPont is exploring the recyclability of carpets made with Sorona® PTT fiber. Research so far shows that carpet fiber made with Sorona® can be removed from the carpet backing and recycled at the end of its useful life. Existing carpet recycling facilities, however, do not accept PTT fiber for recycling today.
Is Sorona® biodegradable?
Answer: Sorona® is neither biodegradable nor compostable.
Is Sorona® a polyester?
Answer: Based on the chemical composition of the product, yes, Sorona® falls into the polyester family. Typical polyester is known as PET. Sorona® is a PTT. And based on the unique performance benefits of PTT, the U.S. FTC awarded a new fiber generic classification to PTT – triexta.
What is the generic name of the polymer?
Answer: Sorona® is a PTT or polytrimethyl terephthalate.
Where can I buy fibers or fabrics made with Sorona®?
