 Full text | Abstract: Coating processes play a significant role in the area of textile production. They are used for technical textiles and special protective clothes to achieve characteristic material properties, for example water-repellency, fire resistance, high temperature protection, etc. In these processes a lot of parameters influence the coating layer’s properties, which are the distance between the knife and material, the speed of the coated material going along the production line, coating paste parameters – viscosity, surface tension and density, and finally the coating material’s properties – surface energy and roughness. In this paper a simulation of the knife over roll coating process is introduced and compared with experimental data taken from the measurement of coating that was applied by a laboratory coating device, Basecoater COATEMA-type, working on the basis of knife over roll technology |
