Droplet height / width method is an overall drop method. When consideration is summarized accounting entire droplet shape is not part of, so when the shape of the droplet was disturbed when other objects, such as needles placed inside the droplets, it will affect the way the accuracy of, and even longer applies. The contact angle is defined as the gas, liquid and solid at the intersection by gas - liquid interface tangent and solid - liquid junction angle θ between the lines, is a measure of the degree of wetting. If θ90 ° contact angle meter high, then the solids are lyophobic wholesale contact angle measurement, i.e., the liquid does not wet the solid and easy to move on the surface and can not enter the pores. The contact angle of existing test methods are usually two: one for the shape of the image analysis method; the other for the gravimetric method which is often referred to as a wetting balance or osmosis contact angle meter, but the most widely used, the measured value is best or directly with an accurate shape of the image analysis method. Principle of the shape of the image analysis method, the liquid drops on the surface of a solid sample, the shape of the droplets to obtain an image with the camera through the lens of the microscope, then the use of digital image processing algorithms, and some of the images The method of contact angle of droplets calculated calculation of the contact angle is usually based on a specific mathematical models such as the droplet can be regarded as part of the ball or conical, and then by measuring specific parameters such as width / height or by directly fitting to the calculated value of the contact angle. Young-Laplace equation describes the interface in a closed, the pressure difference between the outer curvature of the interface the interfacial tension and the relationship between the contact angle meter factory pin can be used to describe a liquid droplet axisymmetric contours accurately to calculate its The contact angle. Role of the yarn in the textile processing and the process of taking the fabric are subjected to a bending moment, bending deformation. Yarns and fabrics are superimposed curved fibers interaction between bending and fiber itself. Interaction between the fibers showed yarn twist in the yarn and yarn transfer, and floating-point performance for a long intertwined in the fabric. Fiber bending performance itself is the fundamental factor of yarn and fabric bending, however, limit the scope of measurement methods and makes textile yarn bending evaluation remains at this level. In the solid appearance of a drop of liquid to be solid - liquid - gas balance of the balance after the three-phase interface system photography, the software supplied through the contact angle measurement methods were measuring the contact angle. It is possible to test the process in a balanced processes punctual photography or video, and then analyze the system change process
