Dupont expands Sorona fibre apparel application
Sep '13
For more than 70 years, DuPont has developed leading-edge technology for the fiber and textile industry. The DuPont Sorona fiber applications team continues that legacy by demonstrating the value Sorona fiber brings to three additional apparel segments – seamless, insulation and comfort stretch fiber.

“From year to year, our applications team conducts research and development along various parts of the textile value chain, identifying opportunities that help our strategic customers enhance their offering with DuPont Sorona fiber,” said Raj Kappali, business manager, DuPont Industrial Biosciences. “We are excited to highlight the value Sorona fiber offers in these additional segments.”

During the most recent Dornbirn Man-Made Fibers Congress, Joshua Lin, technical sales manager for DuPont Sorona, shared performance data highlighting the benefits of fabrics made with Sorona air textured yarn (ATY). For seamless garments, fabrics made with Sorona fiber move moisture on the fabric surface to increase evaporation and cooling and keep garments from sticking to the skin. Results also show when exposed to 40 hours of UV rays, Sorona fiber achieves a 3.0 pass rating for colorfastness.

This year, the company also is highlighting a variety of insulation materials made with DuPont Sorona fiber as an alternative to down and feather filling. The introduction of these insulation materials provide apparel designers with a safe and stable source of supply for staple fiber-fill and down-like insulation.

Insulation made with Sorona fiber can be made in a variety of specifications. The use of Sorona fiber creates more elegant, lightweight garments and offers the same unique compression and recovery characteristics that customers need.

Comfort stretch fiber is a trend that is not going away. Garments made with DuPont Sorona fiber, continue to provide excellent stretch and recovery that keeps the garments in good form, a classic attribute that is necessary in today’s apparel market.
