The present invention provides a method of using a rice peroxidase, particularly rice hull peroxidase, having excellent reactivity at high temperatures and reactivity. Dyed substances (dyes, etc.) are decomposed (discolored/bleached) in a washing liquor by means of a rice peroxidase. More particularly, in the case of washing or rinsing a portion with another portion in the dyed fabric with the same washing liquor, the transfer of textile dyes from the dyed fabric to the other fabric is inhibited. Further, textile dyes in a solution or a dispersion solution are bleached. The invention allows excellent prevention of dye transfer in washing or rinsing and thus provides a method better than bleaching textile dyes in a solution or a dispersion solution, and further a composition for prevention of dye transfer and for bleaching.
A method of preventing the transfer of a textile dye from one dyed fabric to another fabric in the case of washing and/or rinsing a plurality of fabrics including dyed fabric together in a washing liquor, wherein a rice peroxidase acts on the washing liquor in the presence of hydrogen peroxide.
A method of bleaching a textile dye in a solution or a dispersion solution, wherein a rice peroxidase acts on the solution or dispersion solution in the presence of hydrogen peroxide.
(canceled)
A composition comprising rice peroxidase, which is a detergent composition or a bleaching composition.
A composition which comprises a rice peroxidase, a hydrogen peroxide precursor, and one or more kinds of bleaching activators which can generate hydrogen peroxide by acting on the hydrogen peroxide precursor.
