Abstract
3D textile structures with different fibre composition were produced and evaluated in terms of breathability, thermal comfort and antimicrobial activity. Bamboo, cotton, polyester and bioactive polyester were used in proportions ranging from 14 to 72% for the fabrics. Out of the developed materials showing good mechanical and comfort properties, the knitted spacer fabric made up of bamboo and polyester exhibited the best global performance. The results of antimicrobial tests revealed the importance of contact area and type of bioactive agent for antimicrobial protection. Knitted spacer fabrics with 72% antimicrobial fibres, such as bamboo, were not active against the microorganisms tested, whereas knitted flattened fabrics made with the same yarn were effective against E. coli, P. aeruginosa and T. rubrum. The incorporation of thyme oil into the textiles imparted activity against E. coli, S. aureus, C. albicans and T. rubrum. The developed textiles have the potential to be used as footwear lining to prevent athlete’s foot and associated bacterial infections.
