Polyester fibers & blends of polyester/cotton fibers are commonly used in the textile industry. Properties of polyester depends on the production method. Beside the advantages of polyester, there are certain disadvantages that affect the dyeability & dyeing process. By the application of chemical process, such as surface hydrolysis, using of solvents, surfactants & enzymes or physical process like using Plasma, Gamma & UV irradiation some improvement can be made. The UV irradiated fabric (Wavenumber of UV Irradiation is 230-280 nm) was dyed with Disperse & Cationic Dyes, which showed high improvement in dyeability of the fabric with cationic dyes, whereas no pronounced effect was noticed with disperse dyes.
