Fiber contact angle
WebSep 1, 2006 · For contact angle θ >15°, a novel efficient semi-analytic approach was proposed to extract the contact angle from experimental data. The given approach can be used as theoretical basis of... WebMar 23, 2024 · Because the micro/nanostructure formed on the surface of the film decreased, the contact angle of C-30 slightly decreased. This phenomenon indicated that the particle size of the fiber reduced after grinding, and that the nano/microfibrils became the principal component of the fiber suspension.

WebFeb 27, 2024 · The capillary rise on a Wilhelmy plate is a good way to obtain the contact angle by measuring the height of the meniscus created on a partially immersed plate. The contact angle is obtained directly … WebThe contact angle (also referred to as a wetting angle) is the angle formed between the surface of a liquid drop and the surface it's placed on. If the liquid drop spreads out on …
WebThere exist traditional methods for dynamic contact angle measurements of flat surfaces and of fibers with a uniform cross-sectional shape along the fiber. So far, however, no method has been reported which is suitable for structured fibers, particularly for spindle-knotted structured fibers of varying cross-sections. WebContact angle measurement is a qualitative way to evaluate whether the surface has a hydrophobic or hydrophilic characteristic. It is based on the observation of the intermolecular interactions between the surface and a small drop of water when the drop meets the surface. It is mainly used to assess the wettability of a surface.
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 requirements needed for consideration of measuring the contact angle of different fiber types. Key words: single fibers, contact angles, temperature, humidity WebJul 4, 2006 · This paper is concerned with the geometrical shape, wetting length, and contact angle of a microdroplet on a fiber by using the method free energy variation. …
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 ...
