Ultraviolet resistant and antibacterial finishing of cotton fabrics with attapulgite colloid nanoparticles

To develop multifunctional fabrics with ultraviolet resistance and antibacterial properties,the fabrics were finished by attapulgite colloid nanoparticles.The dispersion,structure and properties of the finished fabrics were characterized by means of laser grain size analyzer,SEM,TG-DTA and fluorescence spectrum.The results indicated the particle size of the attapulgite was 100-150 nm and a large quantity of attapulgite particles could be finished onto the fabrics uniformly.The finished fabrics exhibited improved structural and thermal stability,excellent ultraviolet resistance and antibacterial properties,and very slight influence on their style and whiteness.
