The Influence of Dyeing on the Adsorption of Silver and Copper Particles as Antibacterial Agents on to Cotton Fabrics

Abstract

In this paper, the effect of dyeing on the adsorption of silver and copper particles on cotton fabrics was investigated. Vat, direct, and reactive dyes are among the major class of dyes used for cotton fabrics dyeing. In this study, in the first phase, the dyeing of cotton fabrics with direct blue 151, reactive blue 187, and vat blue 6 was performed and in the second phase, the dyed fabrics were immersed and exhausted into a silver and copper solution. The silver and copper solutions were prepared via silver nitrate and copper sulfate salts. The scanning Electron Microscope was applied for morphological study and the elemental analysis was studied by the energy dispersive X-ray. The reflection factor of dyed samples before and after immersion in silver and copper solutions was monitored by using reflectance spectrophotometer analyses. By dyeing cotton with mentioned dyes and usual methods, adsorption of metal on the cotton samples increases. The obtained data show that vat-dyed samples can absorb more silver and copper particles in compare with other dyes. This study may offer an easy way to absorb more amounts of metallic salts as antibacterial agents.
