The so-called contact angle is dropping a droplet on a solid horizontal plane, solid appearance on solid - liquid - gas three-phase bordering point, the gas - liquid interface and solid - liquid interface of two tangents when the liquid sandwiched therebetween the angle formed. Contact angle measuring instrument used to measure the primary liquid contact angle on a solid, namely liquid wettability of the solid, the instrument can measure a variety of liquid contact angle on a variety of materials. The instrument for petroleum, printing and dyeing, pharmaceutical, coating, dressing and other professional research and production has a very important role. When the droplets in the free space is not affected by the force field, the presence of the interfacial tension and the cylindrical ball. But the water contact angle measurement, when a droplet in contact with a solid plane, which eventually shape depends on the relative size of the adhesion of droplets and droplet internal cohesion between solid. When a droplet placed on a solid plane, the droplets can automatically start to shop in the solid appearance of the contact angle measuring instrument price, or the appearance of a solid contact angle of droplets must exist. 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 video contact angle measurement, to be solid - liquid - gas balance of the balance after the three-phase interface system photography, the contact angle measurement methods through the contact angle measurement software will be supplied. Also able to test the process of balancing processes punctuality photography or video, and then analyze the system change process ShengDing instrument (Figure), powder contact angle measurement, contact angle measurement provided by the Dongguan City Sheng Ding Precision Instrument Co., Ltd. .
