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

摘要

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.
