Fabric having ultraviolet radiation protection, enhanced resistance to degradation, and enhanced resistance to fire

摘要

A method for treating a fabric for ultraviolet radiation protection, enhanced resistance to degradation, and enhanced resistance to fire is disclosed which comprises the steps of adding zinc oxide nanoparticles to a solution of 3-glycidyloxypropyl-trimethoxysilane, placing a fabric in the mixture of zinc oxide particles and 3-glycidyloxypropyl-trimethoxysilane, curing the fabric, and washing the fabric. Other methods of treating a fabric are disclosed.

1. A method for treating a fabric for ultraviolet radiation protection, enhanced resistance to degradation, and enhanced resistance to fire comprising the steps of:
suspending zinc oxide nanoparticles in a mixture of an aqueous buffer and an organosilane or phosphonate with a reactive group, adding multidentate ligand to form a durable reactive layer on the zinc oxide nanoparticles, and adding an oxide, alkoxide, or salt of a metal other than zinc to form a surface layer of an oxide other than zinc oxide on the zinc oxide nanoparticles; collecting the zinc oxide nanoparticles by centrifugation; washing the collected zinc oxide nanoparticles; re-suspending the zinc oxide nanoparticles in a buffer; adding the zinc oxide nanoparticles in the buffer to a solution of 3-glycidyloxypropyl-trimethoxysilane; placing a fabric in the mixture of the zinc oxide particles and 3-glycidyloxypropyl-trimethoxysilane; curing the fabric; washing the fabric; and exposing the fabric to ultraviolet radiation.
