Patent number: 4681820Abstract: An electrically conducting material including a polymeric material having adsorbed sulfides of a first metal selected from copper, cobalt, tin, mercury and lead and of a second metal selected from silver, gold and elements of the platinum group. The polymeric material is in the form of powder or a shaped body such as a fiber, film or string and is formed of a synthetic polymer without cyanic groups such as a polyester or a polyamide or a naturally occurring polymeric substance such as silk or wool. The electrically conducting material may be prepared by treating the polymeric material with hydrogen sulfide, and then treating the resultant material having absorbed hydrogen sulfide with (a) a source of ions containing the first metal, (b) a source of ions containing the second metal and, optionally, (c) a sulfur-containing compound to form sulfides of the first and second metals adsorbed by the polymeric material.Type: GrantFiled: May 22, 1985Date of Patent: July 21, 1987Assignee: Nihon Sanmo Dyeing Co.Inventors: Shinji Tomibe, Reizo Gomibuchi, Kiyofumi Takahashi

Patent number: 4410593Abstract: Electrically conducting acrylic and modacrylic fibers are prepared by subjecting the fibers to a first heat-treatment in a bath containing a copper compound and a reducing agent to adsorb monovalent copper ions within the fibers. The heat-treated fibers are washed thoroughly and then subjected to a second heat-treatment in the presence of a sulfur-containing compound to convert the adsorbed monovalent copper ions to copper sulfide. The electrically conducting fibers have superior conductivity which is not lost in repeated washings. The electrically conductive fibers can be dyed readily with cationic dyes without loss of electrical conductivity. The electrically conductive fibers of the present invention possess the touch and other physical characteristics of the starting acrylic or modacrylic fibers.Type: GrantFiled: September 3, 1980Date of Patent: October 18, 1983Assignee: Nihon Sanmo Dyeing Co., Ltd.Inventors: Shinji Tomibe, Reizo Gomibuchi, Kiyofumi Takahashi
