Investigation of the Effect of Various Natural Dyes on UV Protection Properties and Antibacterial Activity of Cotton Fabrics

ABSTRACT

In this research work, natural dyes (Turmeric, Cinnamon, and Saffron) have been successfully used to dye cotton fabrics that are safe to the environment and health during manufacturing and usage. Also these dyes are considered to be nontoxic, nonpolluting, non-carcinogenic, and eco-friendly. Copper sulfate (CuSO₄) was used as mordant in the dyeing with Turmeric, Cinnamon, Saffron dyes on cotton fabric. After dyeing, the UV protection properties and antibacterial efficiency of cotton samples were evaluated and morphological properties of samples were investigated using scanning electron microscope. Color intensities, reflection, and transmission factor of dyed fabrics were measured using a UV–VIS–NIR Reflective Spectrophotometer. The results show that Saffron dye has higher ultraviolet protection properties among the other used dyes and also according to the antibacterial analysis, it can be said that turmeric showed better antimicrobial properties.

摘要

本文研究了eri丝/细旦涤纶/竹材、eri丝/细旦涤纶/tencel电镀互锁织物及其吸湿性能. 研究了原料组合和织物结构对针织物吸湿性能的影响. 在这项研究中，已开发出两种类型的电镀互锁针织结构. 外层由竹/天丝纱（14.8tex）组成，中间层由125旦涤纶（125旦）组成，中间层与更多的褶裥点相连，下一层由eri丝纱（14.3tex）组成. 结果表明，织物组织对水分管理性能有很大影响. 与eri丝/细旦涤纶/竹纤维和tencel组合相比，eri丝/细旦涤纶/竹纤维/tencel组合针织物具有优异的吸湿性能.
