Joining the great performance and sustainability is the clothing dilemma of the twenty-first century. Efforts have beenmade to invent new functional fibers without harming the environment, during the manufacturing process, or even after theproduct use. COCONA® is a polyester yarn widely employed in sportswear for athletes, given its capacity to maintain thecore temperature at an optimal range. The sustainable program launched by this yarn producer depicted adding a biodegradablecharacter to their products while preserving the original functionalities. Our study aims to compare the wear comfortproperties namely the air permeability, the water vapor permeability and the drying behavior of the two yarns (regular andbiodegradable). In this study, six knitted fabrics were produced: where three using the regular COCONA® yarn and threeusing the biodegradable COCONA® yarn with the same pattern and machine settings. Results showed that using the biodegradableCOCONA® yarn increases the breathability and improves the drying capacity of loose knitted fabrics and it has nosignificant effect on tightly knitted structures.
