The dyeing behaviour of methacrylic acid grafted polypropylene fibre with a disperse dye (Dispersol Red B‐3B) under infinite dyebath conditions has been evaluated. It was found that uptake of dye by the fibre is considerably improved by grafting. The rate of dyeing and the diffusion coefficient also showed marked increases in the grafted samples. Theresults have been explained in terms of the structural changes in the fibre effected by grafting.
