The role of dyes extracts from plants in protecting natural fabrics

The safest protection from UV radiation (UVR) exposure is provided by clothing and depends on fabric composition (natural, artificial or synthetic fibers) and parameters (porosity, weight and thickness), as welI as dyeing methods and properties (natural or synthetic dyes, dye concentration, UV absorbing properties, etc.). UV protection properties of dyes extracts from Rubia peregrina L, Daphne gnidium L., Helichrysum italicum L. , Lavandula stoecas L. applied with two different mordants (potassiurn alum and chestnut tannins) were investigated on flax and cotton fabrics. D. gnidium L. and H italicum L. extracts were also applied on wool fabric to test textile resistance to mature larvae of T bisselliella and the oviposition deterrence activity.
