Abstract
Nonfluorescenced fabrics (cotton, rayon, wool and nylon) used for baby wears were washed in heavy duty or light duty detergents, respectively formulated by Fluorescent Brightening Agents (triazinyl stilbene, distyryl biphenyl or coumarin derivative). The amount of sorption of FBAs on the washed fabrics were determined by absorption of extracted solutions and the relative fluorescence intensity of the fabrics, and its desorption from the soaked fabrics in artificial sweat, urine and saliva solutions were also determined by absorption of the humour solutions. Effects of washing temperature (20°, 40°, 60°C) on FBA sorption varied with the combinations of the fabric material and FBA. At higher washing temperature, the desorption rate of FBAs from the fabrics into the sweat, urine and saliva solutions decreased. As the amount of desorption of FBAs from the fabrics were much more in distilled water than in the artificial humours, sufficient rinsing would be the most effective means for the baby wearer to protect against the FBAs.
