Application of Gamma Irradiation for the Functionalization of Textile Materials

Abstract

This work focuses on the synthesis of multiple studies made on the investigation of gamma irradiation effects on textiles. Gamma radiation is used in the research for improved dyeing or to change the mechanical properties of textile and in some cases to reduce the ecological impact of the processing methods. One study researches the effects of gamma irradiation on specific composites such as silk with polypropylene and E-Glass with polypropylene and the changes of their mechanical properties, showing that the mechanical properties of the silk composite increase more compared to the E-Glass composite. The application of gamma irradiation in the process of dying polyester textiles can be used to reduce the dyeing temperature. Studies were made even on the effect of gamma irradiation only on dyes and the possibility that it can reduce wastewater production, resulting in the fact that gamma irradiation can result in the degradation and discoloration of dyes in water depending on the dose and dye used. In one study it was researched if gamma preirradiation can affect the growth of microorganism on the textiles for three different fibers. One study was made on reinforcement of synthetic fibers and compared the effect of ebeam radiation and gamma radiation. It resulted that the effects are similar while gamma radiation affects the mechanical properties more than e-beam.The synthesis of the literature review has lead to the development of a conceptual application model for gamma irradiation in the field of textiles.

04. Recent techniques of surface modification for textile fabrics

“…Silk fabric samples irradiated with a dose of 100 kGy show a clearly higher susceptibility to bacterial biodegradation than unirradiated samples. [45] Enhancing the binding of the ZnO nanoparticles with cotton fabrics can be achieved after irradiation by gamma ray of 9 kGy. This suggests that there is an increased level of binding between the functional nanoparticles which have been coated on cotton fabrics after gamma ray irradiation, which can be useful for the textile industries.…”
