Making fabric repel water involves creating a surface that doesn’t allow liquid to penetrate. This is achieved through various treatments that alter the fabric’s surface tension, causing water to bead up and roll off. These methods range from DIY solutions to professional applications, each offering different levels of durability and effectiveness for making your cloth hydrophobic.
Understanding Hydrophobicity: Why Does Cloth Get Wet?
Fabrics are typically made of fibers that have a natural affinity for water. This is due to the presence of hydrophilic (water-loving) molecules within the fibers. These molecules attract water molecules, allowing them to spread across the fabric’s surface and eventually soak through. This is why a cotton t-shirt gets heavy when it rains.
