Expanded Surface Area Fibers: A Means for Medical Product Enhancement

Expanded surface area fibers in the 4DG geometry provide about three times the amount of specific surface per denier compared to circular fibers. Fabrics made from these fibers provide greater loft, fluid movement, and particle capture than traditional woven, knitted, or nonwoven structures. This paper includes a description of these fibers and a listing of medical product applications that might benefit from their incorporation.
