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 *** 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 *** released amount of phosphorus was evaluated by the inductively coupled plasma(ICP)according to ISO NF EN 16711-2 *** results revealed that the release of P into the aqueous medium is lower than in the artificial *** 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 *** 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 *** observations were also carried out on the fabrics after desorption in order to show the impact of desorption on their ***,the impact of P release on the tensile strength of CO and PES fabrics was investigated using a uniaxial tensile *** thennal stability of all samples before and after desorption was assessed by thermogravimetric aiialysis(ATG).
