Abstract
The effect of low temperature plasma (LTP) on polyester (PET) is investigated by examining the changes in the dyeing properties of treated PET fabrics. An optimum condition for LTP treatment is determined by orthogonal analysis and this treatment condition was used through out the study. After LTP treatment, the PET fabric samples exhibit better hydrophilicity and the dyeability of the fabric is increased and such improvement is more pronounced in the case of high energy disperse dyes. Scanning electron microscope (SEM) observation also reveals that the surface of the treated PET fibre becomes rough with the formation of microtroughs.
