Abstract:

This research studied the influence of thermo-fixing temperature and binder concentration on the fixation of microcapsules with Eucalyptus essential oil to yarns and terry fabrics as well as physical properties of textiles with microcapsules. SEM micrographs confirmed that the grafting of microcapsules onto yarns spun from cotton, grey linen, bleached linen, ramie and bamboo fibres as well as onto ramie-cotton terry fabrics was effective. We conclude that a thermo-fixing temperature of 160 °C and higher caused the deformation of microcapsules or the partial or entire loss of an active product of the majority of microcapsules. Larger microcapsules were commonly damaged faster and were worse than smaller ones. It was determined that variation of the binder concentration from 20 to 95 g/l increased the area density of ramie/cotton terry fabric 1.7 times. The area density of terry fabric grafted with microcapsules in relation to the weft density could be described by linear equations.
