Sontara® is a DuPont registered trademark for fabrics made at its Old Hickory site using hydroentangling technology – a nonwoven process also known as spunlacing.
DuPont’s Old Hickory site is the largest spunlacing facility in the world.
From hospital gowns to imitation leather to wipes to window shades, DuPont Spunlace® fabrics are converted into an almost infinite number of products that perform just as many functions.
For example, since Spunlace® was first made at Old Hickory in 1973, it has become the leading choice of surgeons and nurses in operating rooms across North America. To date, garments of Spunlace® fabric have protected doctors and nurses in more than 200 million surgical procedures. In fact, every week in the United States, more than one million people are protected during surgery with gowns and drapes made of Spunlace® fabric made at the Old Hickory site.
