Characteristics of cotton fabric dyed with Euphorbia extract at different concentrations of cellulosic nanoparticles (CNP)

Abstract

As the perception of the consumer's environment and the toxicity of synthetic dyes that is harmful to humans, interest in natural dyes is also increasing in the textile dyeing industry. This study performed an alternative to metal mordants and used cellulose nanoparticles (CNP) as a natural mortant for dyeing cotton fabrics with natural dyes extracted from Euphorbia. The characteristics with and without CNP mordant were investigated in the experiment. The effects of natural cellulosic mordants were analyzed through color, fastness, color, fastness, air permeability, antibacterial rate, UV protection, and total hand value (THV). As a result, the light fastness has been shown to significantly increase, but the improvements in terms of the wash, perspiration, and rubbing fastness were negligible. In addition, when CNP was added to cotton dyeing, there was no difference change in air permeability, but THV was significantly improved to 5 or more, and the UV protection and bacteria reduction rate were excellent. These results are attributed to the groundwork for studies on other types of natural dyes in the future and, by establishing the benefits of CNP, this study significantly contributes to the improvement of the end-products of dyeing.
