Abstract

The invention discloses a functional nano textile and a preparation method thereof. The preparation method of the functional nano textile comprises the following steps: (1) in an organic solvent, reacting inorganic nanoparticles containing hydroxyl on the surface with a compound containing a group and carbon-carbon double bonds, to obtain modified inorganic nanoparticles, wherein the group can react with the hydroxyl; (2) conducting graft copolymerization on the modified inorganic nanoparticles obtained in step (1), monomers A and textiles, thereby obtaining the functional nano textile. According to the preparation method, the addition of a bonding agent, resin or a cross-linking agent is not required, the handfeeling, air and water vapor permeability and other properties can be furthest kept, and the preparation method is suitably used for garment textiles, is lower in cost and suitable for batch production. The functional nano textile has excellent washing resistance and excellent wear resistance, and is durable in functions.
