Abstract
The textile industry is a major waste producer due to its high production volume and increasing consumption rates. Therefore, recycling and re-using textile waste for production is crucial for environmental sustainability. This study examines the physical properties of cotton/polyester blended knitted fabrics produced with yarns containing four different recycled cotton fiber ratios. In the first part, yarns with varying recycled fiber content were evaluated for unevenness, tensile strength, and friction properties by changing yarn count and twist. In the second part, rib and interlock fabrics were knitted, and fabric tests for weight, thickness, bending rigidity, bursting strength, air permeability, and pilling were conducted. Reference fabrics were produced using virgin yarn with the same blend ratio as the highest recycled fiber yarns for comparison. The results show that recycled yarns can replace virgin yarns, contributing to reducing environmental impacts through textile waste recycling, and recycled yarn quality significantly affects fabric properties.
