Influence of Relative Humidity on Electrical Properties of Textile Laminates

The aim of this paper is to determine the influence relative humidity on comfort and electrical resistance properties textile laminates in order predict possible changes footwear protection levels. Four different structure fibre nature were selected for study. It was determined that water vapour absorption strongly depends storage environment. ability increases about 1.8 – 3 times as from 65 % up 95 %. degree increase laminate materials layers. protective can be influenced by structure, thickness, humidity, voltage laminates. For composed natural synthetic fibres polymer foam insulators, resistivity with thickness layer. At low (U = 100 V), tested became insulating materials, exceeded threshold values antistatic all ranges. high 500 V) drops dramatically when air level depend amount moisture absorbed layer materials. possessed environments humidity. In a environment, turned antistatic, except without polymeric membrane, which conductive.
