Whiteness Index and Intensity Profile of Selected Essential Oils on Cotton Fabric
2010
Devinder Kaur, | Grewal, Neelam
The present investigation was undertaken to study the effect of concentration of four different microencapsulated essential oils namely lemon and pine on the intensity profile of woven and eucalyptus and jasmine on knitted cotton fabrics. The CIE LAB values of the treated substrates revealed that the essential oils led to a slight yellowness of the substrate, the maximum being with eucalyptus oil (87.85). Further, an increase in the concentration of essential oils, from 25 to 35 and 45 per cent led to an increase in the moisture absorption. The effect was more pronounced in knitted substrates, 27.82 per cent at 45 per cent in comparison to the woven ones, i.e. (14.86 per cent at 45%) after 10 launder-o-meter washings. Pine oil (2.40) held the maximum fragrance, followed by jasmine (2.20) and eucalyptus oils (2.10). Lemon oil showed minimum intensity rating of 1.90 after 10 washes.
