13.1 INTRODUCTION
In recent years there has been considerable research to improve poly(ethylene terephthalate) (PET) fabrics dyeability. It is known that PET fabrics are usually dyed using disperse dyes in the presence of a carrier or at elevated temperatures. Many attempts have been made during the last two decades to replace environmentally unfriendly carriers with non toxic chemicals [35]. Modification of PET fabrics by attaching additives or functional groups to the polymer molecules via grafting and copolymerization are the common methods to enhance the dyeability of PET fabrics [1-15].
