Scanning electron microscope image of a bend in a high surface area polyester fiber with a eight-lobed cross section. I took the picture for my textile thesis work in 2000 es una sensacion.l

In 2000, Eastman Chemical Company and Procter and Gamble donated equipment, patents, and intellectual property to Clemson University. These patents gave Clemson University the right to produce, research, and commercialize capillary surface materials (CSM) technology and capillary channel film (CCF) technology. The donation of these technologies allowed Clemson University to combine the knowledge and move the CSM and CCF research forward. (K. Bitz, “Clemson takes on commercialization,” Nonwovens Industry, vol. 34, pp. 76– 78, May 2003).

The fiber image above originally had the code name 4DG - DG meaning deep groove and 4 was the code name for the polymer in this case PET.
