Patent number: 8114791Abstract: 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: July 27, 2007Date of Patent: February 14, 2012Assignee: Sage Automtive Interiors, Inc.Inventors: Andrew D. Child, Alfred R. Deangelis

Patent number: 7151062Abstract: A textile made at least in part with conductive yarns for the purpose of generating heat from an electrical power source. The textile has conducting yarns, or “heaters”, with conductivity and spacing tailored to the electrical source to be used and the heat to be generated. The heater yarns have a positive temperature coefficient whereby the resistance of the yarn increases with an increase in temperature and decreases with a decrease in temperature. “Leads”, such as conductive yarns, can be used to supply electricity to the heater yarns. A coating to the textile can electrically insulate the textile as well as provide protection to the textile during activities such as laundering or use.Type: GrantFiled: April 25, 2003Date of Patent: December 19, 2006Assignee: Milliken & CompanyInventors: Alfred R.
