Abstract
A method for dyeing a modacrylic/cellulosic fabric includes the steps of providing a fabric comprising modacrylic fibers and cellulosic fibers. An aqueous vat dye composition comprising water and a vat dye is applied to the fabric to provide a vat dyed modacrylic/cellulosic fabric. The vat dyed modacrylic/cellulosic fabric is dried. The vat dyed modacrylic/cellulosic fabric is then contacted with a reducing agent. The vat dyed modacrylic/cellulosic fabric is then steamed to promote dye penetration into the fibers. The vat dyed modacrylic/cellulosic fabric is then washed in a first wash step with a wash composition comprising water to remove excess vat dye and reducing agent. The vat dyed modacrylic/cellulosic fabric is contacted with an oxidation oxidizing agent. The vat dyed modacrylic/cellulosic fabric is washed in a second wash step to remove excess oxidation agent.
