Development of Combat Uniform Fabrics Exhibiting Durable Electrostatic Dissipation Properties
Abstract
DuPont developed a new electrostatic dissipative fiber called P140. Seven yards of fabric, containing warp and filling bands of various blends of cotton, nylon, and P140, were manufactured to determine the appropriate fiber ratio to achieve the desired electrostatic dissipative performance. These fabrics were tested for electrostatic decay properties initially, after 5, 10, 20, and 30 wash cycles. Most all of the fabrics containing P140 fiber accepted at least the minimum required level of 4000 volts and demonstrated overall decay times of less than 0.5 seconds through 30 wash cycles. One percent P140 was selected as the optimum level for long term durability and protection and was further evaluated in the standard nylon/cotton twill configuration. Three hundred yards of the Temperate Battledress Uniform (BDU) fabric were manufactured with 50 percent cotton, 49 percent nylon, and 1 percent P140. The addition of 1 percent P140 fiber to the nylon and cotton blend fabric resulted in durable electrostatic dissipation through 30 wash cycles and did not detrimentally affect physical, colorfastness, shade or infrared reflectance properties.
