Used for processing nanoscale primary particles of the mixed oxides, the textile materials and their preparation and SiO2

摘要

And other metal oxides SiO _2, I describe the nanoscale primary particles of mixed oxides of the Al ₂ O ₃ in particular or SiO _2. And has a negative charge and the average particle diameter (measured by the method of measuring the particle size ZetasizerNS device according to (Nano Series)) 1~2000nm, these can be used advantageously for the hydrophilic coating of the fabric material. Can be formed here in the hydrophilic material on which had been pretreated with the case the outer layer of hydrophobic having dispersibility driving to oil and alcohol that is improved as compared with the fabric material having no hydrophilic interlayer. It is particularly advantageous if the nanoscale primary particles are used for the purposes of (in statu nascendi) are intact in the reaction solution.
