Sažetak
Household textiles are exposed to washing and drying cycles over the use stage (textile care). Textiles are in contact with water, chemicals, high temperatures, and mechanical stress during both processes, affecting their appearance and usability. The laundry and drying process in a rotating drum causes thermal and mechanical stress (cyclic deformation, abrasion), which may cause damage down to the molecular scale. By using inadequate parameters, drying becomes one of the most aggressive processes during daily garment usage, resulting in changes in the physical and mechanical properties of fibres/textiles, affecting the shortening of the garment's lifespan. Having this in mind, the research carried out within the project "Low emission household tumble drying with an evaluation of damage to textile materials" focuses primarily on the identification and evaluation of changes at the molecular scale, exerted by the exposure of the respective fabrics to an increased number of wetting/drying cycles. To this end, X-ray diffraction (XRD) and thermogravimetric analysis (TGA), were applied to examine the alteration in crystallinity and thermal degradation profiles, respectively. The research was conducted on a wide range of fabrics, i.e., cotton, polyester, cotton/polyester blend, wool, silk, polyamide, polyacrylonitrile and viscose.
