Flame retardancy and UV protection of cotton based fabrics using nano ZnO and polycarboxylic acids

► ZnO nanoparticles were applied on cellulosic fabrics. ► Application was through different polycarboxilic acids with SHP as catalyst. ► Effect of concentration of SHP on flammability and UV-protection are investigated. ► 6% SHP increase the flame-retardant of the treated cellulosic fabrics.
