ABSTRACT

Surface conductance is one of the main parameters which describes basic characteristics of specific textile materials. These textile materials are used, for example, in environments with higher requirements on hardware electrostatic protection during their production process. Published measurement standardized methods are followed by modeling methods which do not reach satisfactory results. This paper is therefore focused on the modeling of surface conductance of textile materials. The results show that the structure of textile materials can be seen as serial-parallel connections of resistors. A derivation of this model is described.

Keywords: derivation, surface conductance, textile material.

 

RESUMEN

La superficie de la conductancia se encuentra dentro de los parámetros principales de materiales textiles específicos y describe sus características básicas. Estos materiales se usan por ejemplo en situaciones donde se requiere una protección electroestática para el hardware durante el proceso de producción. Los métodos de medida estándares publicados siguen métodos modelados que no alcanzan resultados satisfactorios. Por lo tanto, este informe se enfoca en modelar la superficie de la conductancia de materiales textiles. Los resultados muestran que la estructura de los materiales textiles pueden considerarse como conexiones de resistencias serie-paralelo. Se describe, además, una derivación de este modelo.
