Patent number: 7635517Abstract: The invention includes fabrics that have been dyed or finished with a dye that contains a conductive mixture of conductive organic materials, inorganic materials, metals, metal oxides, carbon and carbon nanotubes or combinations or mixtures thereof. The dye is used to finish a fabric such that it is conductive. These fabrics are useful in shielding law enforcement personnel from energy weapons discharge and in providing an electrostatic medium for personnel that work with static sensitive products. The fabrics, when appropriately grounded, dissipate the emitted charge and transmit it to ground. Additionally, the apparel has high wear resistance and is both thermally and electrically conductive yet is comfortable to wear.Type: GrantFiled: February 7, 2006Date of Patent: December 22, 2009Assignee: Mystic MD, Inc.Inventor: Joel S. Douglas

Patent number: 7635439Abstract: The present invention relates generally to a static dissipative textile having an electrically conductive surface achieved by coating the textile with an electrically conductive coating in a variety of patterns. The electrically conductive coating is comprised of a conducting agent and a binding agent, and optionally a dispersing agent and/or a thickening agent. The static dissipative textile generally comprises a fabric which may be screen printed or otherwise coated with a conductive coating on the backside of the fabric so that the conductive coating does not interfere with the appearance of the face of the fabric. The economically produced fabric exhibits relatively permanent static dissipation properties and conducts electric charge at virtually any humidity, while the conductive coating does not detrimentally affect the overall appearance or tactile properties of the fabric.Type: GrantFiled: April 20, 2006Date of Patent: December 22, 2009Assignee: Milliken & CompanyInventors: Andrew D. Child, Alfred R. DeAngelis

Publication number: 20090298368Abstract: A finishing composition is proposed for deposition by continuous flow inkjet technique onto a textile substrate. The composition comprises a dispersion or emulsion of a functional finishing agent in a vehicle and the jetted composition has a conductivity of greater than 500 ?S/cm. The size of particles in the dispersion or emulsion of the finishing composition is less than about 5 microns. By ensuring sufficient fineness of the particles, effective and reliable droplet deposition may proceed without clogging of the nozzles.Type: ApplicationFiled: March 22, 2006Publication date: December 3, 2009Inventors: Johannes Antonius Craamer, James E.
