Chemical compounds that give water repellent characteristics to fabrics are usually fluorocarbon-based. The main issue concerning fluorocarbons is not their performance efficiency but the presence of two by-products called PFOS and PFOA, which are persistent, bio accumulative, and toxic chemicals. In our project, using the melt spinning method, we aim to produce a durable polyester yarn with a special additive that provides carbon-free water repellency.

The successfully concluded SCPE project identified a high fastness masterbatch, UV combinations, and parameters. In our current project, we are utilizing these findings with the goal of incorporating hydrophobic characteristics into our product through the melt spinning method. In this project, it will be determined whether hydrophobic PET yarns, resistant to outdoor conditions, provide a performance advantage against 1000 hours of artificial outdoor conditions. Factors that may arise at each stage of yarn production will be examined. Our objective is to explore solution methods related to the identified factors, with the aim of optimizing the yarn to attain its peak performance level. This way, our product will maintain its performance throughout the material's lifespan in outdoor use, while preserving its hydrophobic feature throughout its usage life.
