Main description (English)

The aromatherapy textile of cinnamon oil comes from a compound found in the essential oil called cinnamaldehyde. With the antibacterial and anti-inflammatory properties that can help treat certain metabolic, infectious, digestive or respiratory disorders, this compound is also very volatile. Moreover, cinnamon essential oil can help treat dermatitis, but the coumarin compounds found in essential oils can cause skin irritation. Therefore, encapsulation is currently the best solution to improve evaporation and keep the fragrance of essential oils on fabrics longer and reduce large amounts of pure essential oils in direct contact with the skin. In this study, we have investigated the odor fastness of Eugrarit RSPO microcapsules contained the cinnamon essential applied to the surface of interlock fabric knitted byChief Value Cotton (CVC) yarn (60% cotton, 40% polyester). The fragrance durability of the knitted fabrics coated by pure cinnamon essential oil and the microcapsules contained cinnamon essential oil had been evaluated. The influence of the pressure of knitted fabric band coated by the microcapsulecontained cinnamon essential oil induced by extension levels of 21.25%, 57.5%, 68.75%, 83.75% had been studied. The fragrance durability evaluation was based on the combination of the expert method and diluted solution method. The results showed that the fragrance intensity of knitted fabrics treated by pure essential oil was stronger but the diminution of their fragrance was faster than these ones treated by the cinnamon essential oil microcapsules. Besides, the higher the extension applied on the fabrics band,the smaller their fragrance intensity had been maintained.
