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.

摘要

研究了染色对棉织物中银、铜吸附的影响。还原染料、直接染料和活性染料是棉织物染色的主要染料品种之一。在这项研究中，在第一阶段，直接蓝151的棉织物的染色，活性blue187和还原蓝6进行第二阶段，染色织物浸泡和排出到银和铜溶液。以硝酸银和硫酸铜盐为原料制备银铜溶液。采用扫描电子显微镜（SEM）进行形态研究，用能谱仪（EDX）研究元素分析。采用紫外可见分光光度计对染色前后样品在银和铜溶液中的反射系数进行了监测。采用上述染料和常用方法对棉进行染色，使金属对棉样品的吸附增加。所得数据表明，与其他染料相比，还原染料样品可吸收更多的银和铜颗粒。这项研究可能提供了一种简单的方法来吸收更多的金属盐作为抗菌剂。
