PURPOSE:To provide an industrial and economical process for dyeing exclusively a protein fiber of a conjugate fiber structure composed of protein fiber/polyester fiber without staining the polyester fiber. CONSTITUTION:A conjugate fiber structure composed of a protein fiber and a polyester fiber is dyed by using a vinylsulfone-type reactive dye as the dye, fixing the dye and subjecting the dyed product to reduction and washing treatment. The protein fiber can exclusively be dyed without staining the polyester fiber by this process. |
