Researchers from Cornell University and the University of California (UC), Davis in the U.S. are developing clothing made of porous membranes and bacteria-killing molecules for military and medical applications. This technology is based on UC Davis professor Gang Sun’s method of attaching polymer molecules containing chlorine, called halamides, to textile fibers. These molecules kill bacteria on contact and also absorb odor. This technology has already been used by Vanson HaloSource to create anti-bacterial bed sheets and cotton pads for medical use. Sun teamed with Professor Kay Obendorf of Cornell to develop a method of attaching halamides to porous nanomembranes of polyurethane so that they can be applied to clothing as a coating. This material is intended for military use to protect individuals who may be exposed to biological agents. The fabrics still allow for perspiration to escape. The two scientists are now working with the National Textile Center to create fabrics for farm workers who are exposed to pesticides in high temperatures and humidity.
