Patent number: 3941561Abstract: A process of producing a dyed cleaned material comprising first applying to virgin material a dyeing medium, next drying the material and then treating the material with a cleaning substance containing acetone. The acetone may be diluted with water in a proportion up to 50% water. The dyeing medium may be a non-aqueous solvent dyeing medium. The non-aqueous dyeing medium may be combined with a material for which the solvent has an affinity higher than it has for the dye.Type: GrantFiled: July 18, 1973Date of Patent: March 2, 1976Assignee: J & P Coats LimitedInventors: Ronald Barr Love, Alistair Templeton Stewart
