Development and Performance Evaluation of Fluorine-Free Saliva-Proof Cotton Knitted Fabric for Kids' Protection
Main Article Content
Abstract
Using ASUPERLE PWR, a fluorine-free treatment intended to improve moisture resistance without sacrificing comfort or mechanical qualities, this study explores the creation of water-repellent cotton textiles. Because cotton is naturally hydrophilic, it cannot be used in areas that are prone to moisture, necessitating the investigation of sustainable water-repellent materials. Water repellency tests (AATCC 22), scanning electron microscopy (SEM), colourfastness to rubbing (ISO 105-X12), and bursting strength tests (ISO 13938-2) were used to evaluate ASUPERLE PWR on scoured and bleached cotton knit fabric. The results showed that treated textiles had a continuous hydrophobic coating visible in SEM images and an ISO 5 water-repellency grade. Although ASUPERLE PWR improves water repellency, there is a little trade-off in durability, as seen by the minor decreases in colourfastness and mechanical strength that were observed. This study positions ASUPERLE PWR as a promising, eco-friendly alternative to fluorine-based treatments for textiles.
