Migration of particulate matters on nano-functional textiles

To investigate the migration of nano-finished textiles during dressing,the functional fabrics finished with nano ZnO and nano TiO2 were selected,the morphologies and elements of the fibers were observed by scanning electron microscope(SEM) and energy dispersive spectrum(EDS),laser grain size analyzer and inductively coupled plasma-mass spectrometry(ICP-MS)were applied to the identification of the extract solutions at synthetic perspiration /water washing.The results showed that irregular particles dispersed on the surface of fabrics,range from nm to μm,EDS showed they were ZnO and TiO2;synthetic perspiration /water washing could lead to the detachment and dissolution of nano ZnO and nano TiO2,but the particle sizes in extract solutions were μm.
