Abstract: To investigate the security of nano-functional textiles during dressing, select the functional fabrics finished with nano ZnO and nano TiO2 , the morphologies and elements of the fibers were observed by scanning electron microscop(SEM) and energy dispersive spectrum ( EDS), laser grain size analyze and inductively coupled plasma-mass spectrometry （ICP-MS ）were applied to the identifycation of the exeract solutions at synthetic perspiration /water washing. The results showed that irregular particles dispersed on the surface of fibers , range from nm to um, EDS show they were Zn and Ti; synthetic perspiration /water washing could lead to the dissolution of nano ZnO and nano TiO2, but the particle sizes in exeract solutions were um.

Key words: nano-functional textiles, application, security, particle size
