Purpose – The purpose of this paper is to investigate the physical properties of smart aromatherapic ramie/cotton terry fabrics containing microcapsules (MC) with essential Eucalyptus oil. Design/methodology/approach – Terry fabrics are manufactured by changing the weft density. The air permeability is determined for grey and microencapsulated textile. The factorial designs are made. For informative experiment the linear type of regression is analysed. Development of physical properties of microencapsulated terry fabrics is discussed. Findings – The air permeability of aromatherapic terry fabrics is determined. All statistical analysis is performed. Appropriate conclusions about the influence of fabric’s structure and microencapsulating process on terry fabric quality are made. Originality/value – To date there are no investigations concerning terry textiles with fragrance MC. This study developed analysis and empiric mathematical equations suitable for evaluating and designing terry fabrics with the air permeability required. Assessment of the influence of fabric’s weft density and binder concentration for the air permeability of terry textile is proposed.
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.
