Water Repellent Finish. (For Textile Processing)
Water Repellent Finish. (For Textile Processing) Introduction Waterproofing is defined as the property of a material not to be penetrated by fluids. Water repellent textiles are often high-density woven materials made of very fine yarns or common materials with hydrophobic surface treatment. Water repellency is therefore a step up from water resistance. This means that water can't easily penetrate the material. Water repellents are chemical finishes that retains textile material from wetting and also protect the other comfort ability. The droplet of water molecules tends to spread out over the fabric mainly depends on the contact angle between water molecule and fabric surface. Actually, this property adds on the fabric by providing a thin layer on the fabric surface that abstains water droplet from fabric wetting. Chemistry Compounds formed by reacting Stearic Acid (C18H35O2) and Formaldehyde (CH2O) with Melamine (C3H6N6) constitute a...
