Cotton and wool dyeing at different conditions are due to they have different structural characteristics.After determination of fixation rate of reactive dyes on cotton which dyeing in the dyeing liquor that have been treated under the condition of pH value 11,temperature 60 ℃,30 min,and determination of strength at rupture of wool fabric that have been treated under the same condition,the results show that one bath two stage dyeing process of cotton/wool blended fabric with B type reactive dyes is feasible.Match cotton and wool fabrics(50/50,80/50)that can be dyed to the same shade by controlling pH value of dye bath.
