Textile Materials treated with Eco-friendly insectide agents

Research work deals with the possibility to achieve the insecticide properties of the textile substrates treated with ecological friendly insecticide reagents. For this purpose, textiles made of wool, polyester and PES/wool blend were treated with the ß-cyclodextrine and cedar oil which can be used as a moth oppression reagent. Cedar oil forms a complex with the ß-cyclodextrine, which is attached to the textile substrate, from where it can be slowly released. Two processes were used to fix the reagents onto the textile substrate surface: a conventional fixation on tenter and a fixation with microwaves. The advantage of microwaves is the fact that material is heated directly and absorbs energy by the total volume homogenously and selectively. Because of the MW conditions time and energy consumption can be decreased. Different analysing methods were employed:  -cyclodextrin/BTCA amount was evaluated by gravimetric method ; functional group determination was performed using ATR FT-IR as well as Raman spectroscopy ; morphological changes were assessed with the light and electronic spectroscopy and differences to touch before and after the treatment with the KES-FB measuring system.
