We know that functional textiles have some special functions, such as rainproof, fireproof, quick-drying and other functions. These functions are achieved by spraying specific substances on the surface of textiles. At this time, the special substances sprayed need to have good uniformity. It is very important to the quality of textiles, and the contact angle measuring instrument of Sindin comes into play. By analyzing the data of contact angle, surface interfacial tension, surface free energy, etc., Let the product have good quality control and research and development.
Wetting and coating of textiles
The wettability of the fiber or fabric can be confirmed by the contact angle, so wetting before coating should be done as well as possible to ensure the best affinity between the coating material and the fiber. The contact angle also characterizes the final coating, describing the effect of the hydrophobic coating of the fibers. Therefore, it can be used to ensure the quality of the coating process.
