摘　　要：In this paper,phosphate nanoparticles were coated on cotton(CO)and polyester(PES)textile surfaces by sol-gel method using tetraethylorthosilicate(TEOS)and chloropropyltriethoxysilane(CPTS)as silica precursors.The deposited nanoparticles were observed with scanning electronic microscopy energv-dispersive X-ray spectroscopy(SEM-EDX).The release kinetics of phosphorus(P)from these textiles into the aqueous medium(Aq),acid(Ac),and basic(Ba)artificial sweats were then studied.The released amount of phosphorus was evaluated by the inductively coupled plasma(ICP)according to ISO NF EN 16711-2 procedure.The results revealed that the release of P into the aqueous medium is lower than in the artificial sweat.The kinetics data[the phosphoras desorption amount(mg/g)as a iunction of time]were modeled according to five models:the first order,the second order,the third order,simple Elovich and parabolic diffusion.The suitable model was chosen based on the coefficient of determination(R2)and the calculation of the sum of the absolute errors(EABS),which describes the error between the theoretical and experimental values.SEM observations were also carried out on the fabrics after desorption in order to show the impact of desorption on their morphology.Furthermore,the impact of P release on the tensile strength of CO and PES fabrics was investigated using a uniaxial tensile test.The thennal stability of all samples before and after desorption was assessed by thermogravimetric aiialysis(ATG).
