Experimental Study on Fabric Surface Wettability based on Contact Angle and Surface Energy

Bingxuan Ni, Peng Zhang


The paper studies on surface wettability characterization of fabric by using contact angle. According to surface tension of liquid, contact angle between liquid and fabric, based on Owens model, the surface energy of nonwoven surface that has water repellent finishing (sample 2) is 29.54 mN/m, and nonwoven surface that hasn’t water repellent finishing (sample 1) is 43.99 mN/m. The essence of water-repellent finishing is to reduce solid surface energy. The surface tension of liquid drop is lower; the contact angle of droplet and fabric surface is smaller.
