Effect of Polyester Structure on Drying Behavior

The drying capacity of fabrics is an important feature for sportswear. Furthermore, the environmental impact of these products is crucial for the sustainability of the humankind. Combining the eco-friendly feature with clothing comfort is the golden solution. Claims have been made on the comfort level of COCONA® new biodegradable polyester yarn. This study is dedicated for investigating these claims. Six knitted fabrics were made in this work, three were made with COCONA® polyester yarn and three others were made with its biodegradable version. A comparison between the drying time, as a clothing comfort property, of these two groups of fabrics was done on finished and domestically washed fabrics. Results indicate that after finishing and washing, knits made with the biodegradable COCONA® yarn have a superior capacity for drying than knits made with the conventional COCONA® polyester yarn. After the domestic washing cycles, drying times of biodegradable fabrics show a slight improvement compared to the regular ones.
