Functional Finishing of Textiles Using Bioactive Agents Based on Natural Products

There is nowadays an increasing vogue for so-called cosmetic textiles which are essentially garments that are designed to come into contact with the skin, which then transfer some active substances that may be used for cosmetic purposes. In order to obtain the textile materials with potential for use in the development of cosmetic textiles, this study approached the experimentation of deposition by padding and exhaustion of commercial rose microcapsules on knitted textile structures with different fiber compositions. The finished textile materials were characterized in terms of functionalization treatments durability, release of bioactive compounds in sweat solution and antibacterial activity, respectively. In order to identify the functionalization method which ensures the deposition of a high content of microcapsules on the knitted fabric surface, which implicitly leads to a high functional effect, solid-liquid and liquid-liquid extraction method for sample preparation and a gas chromatography with mass spectrometry detection (GC-MS) for identification of active compunds have been involved. SEM analysis was used to investigate the distribution of microcapsules on the textile materials surface, before and after 1 washing cycle and 9000 abrasion cycles. Antibacterial activity of treated samples has been evaluated before and after 1 washing cycle against the Staphylococcus aureus test strains.
