Abstract
Textiles including polyester fibers made from recycled PET bottles have increased to be produced recently. We examined on performance and durability of woven fabrics that include recycled polyester fibers. First, forty-eight commercially available fabrics which include polyester fibers made from PET bottles were collected, and their mechanical, surface and thermal/moisture/air transport properties were measured with the KES-F system for making clear the performance. Second, their durability was investigated by washing repeatedly. The performance of the fabrics had the tendency to increase the values of bending rigidity B and shear stiffness G with the increase of the rate of recycled polyester fibers. The results of durability tests showed that the values of B and G were decreased by washing repeatedly, and that fatigue action such as increasing of hysteresis and decreasing of resilience was not observed clearly.
