NANOSCALAR PARTICLES BASED ON SIO2 AND MIXED OXIDES THEREOF, THEIR PREPARATION AND USE FOR TREATING TEXTILE MATERIALS

摘要

Nano-scale primary particles based on silicon oxide or mixed oxide of silicon oxide and other metal oxide, preferably aluminum trioxide, where the nano-scale primary particle exhibits an average particle size of 1-2000 nm (determined according to measurement of particle size equipment Zetasizer LV(RTM: Submicron size particle analyzer) (nano series)) and a negative charge, are new. Independent claims are included for: (1) a liquid medium comprising a nano-scale primary particle; and (2) use of the nano-scale primary particle for hydrophilic coating of the hydrophobic material.
