DuPont developed a new process to product PTT from corn sugar and calls this fiber Sorona®.
The FTC determined that fibers made from PTT offer a unique combination of benefits which merit a new generic name, Triexta.
This is the fiber used in Mohawk’s SmartStrand®.
It is anticipated that Triexta fibers will resist staining with acid food dyes and be somewhat resistant to disperse dyes (the yellow of turmeric in mustard is an example of a disperse dye).
PTT does have an strong affinity for oil and grease, but should respond well to cleaning if it is done on a regular basis, at least annual, for typical family use.
Properties of Triexta:
- Triexta has a more matte finish, making its appearance look more similar to nylon than to polyester.
- Due to triexta’s hydrophobic fiber, it’s naturally stain resistant.
- Direct exposure to sunlight and UV rays will not cause discoloration of the fiber.
- For stain protection, no chemicals are added to the fiber.
- Triexta is notably softer compared to polyester and nylon.
- Good resiliency.
- Good anti-static properties.
- Resistant to bleach.
- By replacing petroleum with corn glucose during production, fewer chemicals are put into the fiber, which means less VOCs transferred into the air.
- Corterra (PTT) attracts oily soils, leading to premature wear in high traffic areas. For this reason, many oil-based stains are extremely difficult to remove.
