Abstract
When nano-sized tiny roughness is processed on a surface, the prevention of dust adhesion can be expressed by the decreasing of the van der Waals force between rugged surface and dust particle. Using nanoparticle coating on a textile, the tiny roughness can be created on a textile and the preventive effect of dust particle adhesion can be given to the cloth. This effect is applicable to working clothes etc. Generally, clothes are washed in order to remove the dirt on it, so the nanoparticle coating on a textile and the preventive effect of dust adhesion may be decreased by washing process. In order to add the functionality to the preventive effect of dust adhesion on the clothes in a practical uses, the improvement in the durability for washing is very important.
In this research, we confirm the preventive effect of dust adhesion and measured the effect of the number of washing on the preventive effect of dust adhesion on a textile. From our experimental results, the durability of the nanoparticle coating and the preventive effect of dust adhesion can be improved using acetalized polyvinyl alcohol treatment.
