Abstract :
A methed for the reduction of the quenching effects of fluorescent whitening agents (FW As) on textiles has been investigated. The total radiance factors of different samples which were produced by normal after - treatment of coloured fibres were compared with a series of blends of coloured and FWA treated fibres. The higher brilliancy of the blended series indicates lower quenching effects of the FWAs in the blended samples. In spite of higher shade changes in the blended series no other side effects, such as colour broken effects, were observed in the blends in comparison with the normally treated samples.
