- Abstract
- Dimethylaminopropyl methacryamide was photografted onto PET fabrics by continuous UV irradiation under ambient conditions. Several factors affecting the photografting were studied including irradiation energy, monomer and photoinitiator concentrations. ATR and ESCA analysis showed the successful grafting of the monomer onto the PET surface. The grafted PET fabrics showed higher zeta potentials below pH 7 compared with the ungrafted PET. The dyeability of the grafted PET fabrics to two α-bromoacrylamide reactive dyes was investigated under various dyeing conditions including dye concentration, pH, dyeing temperature and time. The grafting imparted the reactive dyeability to PET fabrics, which was proportional to the grafted monomer content. The reactive dyeing behavior of the grafted PET fabrics was similar to that of conventional wool fabrics.
