But its dyeing behaviour is very poor from an aqueous dyebath because of the high degree of crystallinity and the lack of dyeing groups in fibers. Dyeing at high temperature is a better way and more mature technology. But in recent years， individuation， diversification and function of costume are pursued， so the composite fibers are applied widely. The blended PET fabrics with other fibers such as wool， silk， acetate cellulose and spandex and so on are not endured high temperature. Therefore， the dyeing of PET fiber at atmosphere pressure is a developmental current at present. In this paper, polyester fabric was dyed with disperse dye in the presence of methyl methacrylate. The effect of methyl methacrylate on the dyeing properties was studied., especially between the conventional dyeing methods and the new technical dyeing methods when methyl methacrylate appears. The results show that the presence of methyl methacrylate improves the dyeing properties of polyester fabric. The dye uptake and K/S value increase significantly even at a low dyeing temperature.
