Abstract

With regards to environmental conservation, it is necessary to promote an eco-friendly industry and to recycle wastes. In this study, the physical properties and hand values of material recycled PET knit fabrics prepared with various recycled PET yarns were investigated. Bursting strengths of 3 recycled PET knit fabrics were higher than that of regular PET knit fabric. 3 Recycled PET knit fabrics were more flexible than those of the regular PET knit fabric. Lightness of regular PET knit fabric was the highest among the 5 samples. Fabric knitted with recycled non-circular PET yarns had a more yellowish tinge. Mechanical properties were measured using the KES-FB system. Bending properties, shear properties, weight, and thickness were increased in recycled PET knit fabrics. The compressional linearity and energy of 3 recycled PET knit fabrics increased. However, their compressional resilience was reduced. In addition, coefficients of friction were similar. Regular PET knit fabric demonstrated a smooth appearance. Numeri was the highest in the hand values.
