The Dual Impact of Paraffin Wax and Finishing Treatments on Water Proofness and Strength of Raincoats

Abstract

This research investigates the dual impact of paraffin wax treatment and finishing processes on water repellency and mechanical strength of woven textiles. Paraffin wax treatment significantly increased fabric hydrophobicity, as indicated by enhanced water contact angles and reduced water absorption. Simultaneously, the treatment strengthened fabric tensile properties by increasing inter-yarn friction and compactness. However, tear resistance declined due to restricted yarn slippage. Finishing processes, while enhancing surface smoothness and weight uniformity, altered hydrophobicity by removing wax residues and improving water absorption in certain cases. The study reveals the complex trade-offs between hydrophobicity and strength in treated and finished fabrics, emphasizing the importance of selecting appropriate techniques to achieve balanced fabric performance. These insights contribute to the development of textiles with optimized water repellency and mechanical integrity for technical and apparel applications.
