Synthesis of reactive UV absorbers, derivatives of monochlorotriazine, for improvement in protecting properties of cellulose fabrics

A number of colourless fibre-reactive UV absorbers, derivatives of monochlorotriazine were synthesised. Reactivity with cellulose and their properties as auxiliaries increasing UV-protection factor (UPF) of treated cotton fabrics were determined. Changes in protecting properties of prepared absorbers and changes in whiteness of used textiles during prolonged exposition to light were also measured.
