WebAnd the contact angle of bamboo fiber increased significantly, while that of terylene fibers ascended a little. These findings will aid researchers in better understanding the … WebJul 6, 2024 · The advancing angle is measured when the liquid wets the previously dry surface. This is typically done with the so-called needle method, where water is gradually applied on the surface. When the contact line starts to move, the advancing contact angle can be measured. The advancing angle is thought to be more sensitive to hydrophobic ...

To Determine surface energy indirectly WebThe water contact angle measurement was conducted by using a set of goniometers (Kruss Gambult, Germany). A sessile drop method was used to measure the contact angle seen from the fiber horizontal surface. A total of 1 µL of water droplet was introduced on the surface of the fiber, and the image profile of the drop was shown by the software. lowes appliances kitchen stoves
