Assessing Alternative Pre-Treatment Methods to Promote Essential Oil Fixation into Cotton and Polyethylene Terephthalate Fiber: A Comparative Study

This study aims to develop a new refreshing feeling, ecological, and antimicrobial fabrics for medicinal applications. The geranium essential oils (GEO) are incorporated into polyester and cotton fabrics by different methods, such as ultrasound, diffusion, and padding. The effect of solvent, nature of fibers, and treatment processes were evaluated via the thermal properties, the color strength, the odor intensity, the wash fastness, and the antibacterial activities of the fabrics. It was found that the ultrasound method was the most efficient process for incorporation of GEO. Ultrasound produced a great effect on the color strength of the treated fabrics, suggesting the absorption of geranium oil in fiber surface. The color strength (K/S) increased from 0.22 for the original fabric to 0.91 for the modified counterpart. In addition, the treated fibers showed appreciable antibacterial capacity against Gram-positive (Staphylococcus epidermidis) and Gram-negative (Escherichia coli) bacteria strains. Moreover, the ultrasound process can effectively guarantee the stability of geranium oil in fabrics without decreasing the significant odor intensity and antibacterial character. Based on the interesting properties like ecofriendliness, reusability, antibacterial, and a refreshing feeling, it was suggested that textile impregnated with geranium essential oil might be used as a potential material in cosmetic applications.

Automated summary

This study aims to develop new fabrics with refreshing feeling, ecological properties, and antimicrobial functions for medicinal applications. Geranium essential oils (GEO) were incorporated into polyester and cotton fabrics using methods like ultrasound, diffusion, and padding. The results showed that ultrasound was the most effective method for incorporating GEO into fabric, resulting in improved color strength, significant antibacterial activity, and stable odor intensity. The textile impregnated with geranium essential oil was suggested as a potential material in cosmetic applications due to its eco-friendliness, reusability, antibacterial properties, and refreshing feeling.
