title: New textiles of biocidal activity by introduce insecticide in cotton-poly (GMA) copolymer containing β-Cd.
abstract: The present work deals with the preparation of innovative cotton textiles which act against blood sucking insects such as mosquitoes. Thus experiments were designed to incorporation of efficient insecticide (Permethrin, bioallethrin) in the macro-molecular structure of modified cotton fabrics. Chemical modification of cotton was realized by grafting with glycidyl methacrylate alone or in combination with β-cyclodextrin by irradiation using fasting electron beam. Retreatment of the so obtained modified cotton was also made to increase the amount of CDs, and in turn, their cavities within the molecular structure of the modified cottons. Finished fabrics were though evaluated using chemical analysis; physical testing, bioassay tests and IR as well as SEM. Results obtained conclude that the amount of insecticide in the finished fabrics increases by increasing of the fixed amount of cyclodextrins which incorporate through their cavities the insecticide. The bioassay test shows that finished cotton fabrics display fast acting against mosquitoes.
