SOFTWARE BASED ON GRID NETWORK FOR TEXTILE ELECTROCONDUCTIVITY AND RESISTIVITY ANALYZE

Summary/Abstract: The paper present a software application developed by modular programming FORTRAN and distributed computing processes by using Grid Network. The software application goal is to analyze conductivity and resistivity correlation when electricity flows through textile structures (yarns or woven structure with additional inserted conductive yarns on weft direction). The electrical intensity on textile structure was measured by using a digital multimeter, after the connection of the conductive part from textile structure to a source of continuous current. The data used in software are from tests made according to standard SR EN 1149 - 1:2006 - regarding determinations for textile surface resistivity, for vertical resistivity and load dissipation capacity. The electrostatic energy dissipation is a requirement for develop protective garment with electronic devices integrated. The aim of usage conductive yarns in textile area is to obtain flexible conductive structures with possibilities of usage in many areas of interest (military, medical of protective equipment). The textile structures (yarns, knit or woven) can be considered like an anisotropic model and this purpose can conduct to different values for conductivity or resistivity. For this software the surface was considered to be anisotropic and the tests for conductivity and resistivity were performed assuming a grid network model with fixed lengths and nodes. The resistance is associated with contact resistance between neighbouring yarns and numerous contact points at the crossing between yarns in the sample [1]. Tests for the contact resistance between the textile substrate and the electrode are important part of research of electro conductive properties of textiles [1]. This software was realized by suing Grid Network due to the power computing in solving difficult mathematical expressions.
