Functional Upholstery Materials for Protection Against Electrostatic Risk
Research and development

Full text | Abstract: Textile products designed for areas protected against electrostatic discharge (ESD) should be characterised by a very low propensity to generate electrostatic charge. Functional pile knitted and woven textile upholstery materials for different purposes have been designed to meet electrostatic prevention requirements. A comprehensive evaluation of their electrostatic properties was based on the measurement of surface and volume resistance, Rs and Rv, as well as on the charge decay time tested by means of three different methods: triboelectric, induction and corona discharge. The propensity of these materials to charge was also analysed in model conditions simulating the use of a castor chair according to the new, so-called “chair method” developed especially for this purpose. The electrostatic voltage (V) was measured for an operator dressed in different clothing who used castor chairs covered with ordinary fabrics and with the textile upholstery materials designed. All the electrostatic tests were performed at 23 ± 1 °C and 25 ± 2% relative humidity. The materials designed are characterised by permanent antistatic properties: surface resistance Rs = 103 – 1010 Ω; the charge decay half time t50 < 0.01 – 1.80 s and electrostatic voltage V = 0.1 – 0.6 kV. Flame retardant materials meet the requirements for furniture upholstery in public utility buildings and/or for car upholstery. |
