  Abstract

This study examines the disintegration and physicochemical changes of bio-PET and cotton blended fabrics under composting conditions over 22 weeks. Four fabric samples with different compositions and weave structures were evaluated for disintegration through pilot-scale composting based on KS M ISO 16929 standards. Weight loss, thickness reduction, Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM) analyses were conducted. Results indicated that fabrics with higher cotton content and weft solely with cotton exhibited greater disintegration. This was due to enhanced interaction with microbes and moisture, leading to significant weight and thickness loss. Conversely, fabrics of b-PET and cotton weft demonstrated slower disintegration rates. FTIR spectra revealed structural modifications in b-PET and cellulose of all specimens, such as weakened C=O bonds and cellulose ring breakdown. Thermal analysis revealed reduced crystallinity in b- PET in fabrics with weft made entirely of cotton. In contrast, b-PET in fabrics with alternating cotton and b-PET weft exhibited increased crystallinity. Morphological observations confirmed fiber disintegration, particularly in cotton. These findings suggest that fabric composition and weave patterns significantly influence biodegradability, providing insights for developing sustainable bio-composite textiles.
