Sažetak
The objective of the study was to test the electrostatic properties of textiles used for protective cloting worn in flammable and potentially explosive environment. The protective clothing is intendent for multi-use and, apart from wear and stretching during use, it is also exposed to inpacts of various cleaning agents. The testing was carried out in accordance with EN 1149-1 ; 1995 specifying requirements for electrostaticproperties and testing metods for protectivecloting to bi worn in specific situations. The objective was to test whether there was a likelihood of fire due tu theelectric discharge. EN 1149-1 requires measuring surface resistance at 25 2 per cent relative humidity and temperature of 23 1 C. Measurrement were taken on knitting of wariying materials coated with polyurthane. The knittings used were made of polyamide, polyester and cotton. All materials werecoated with the same polyurethane coating. All samples were tested for surface resistance befor and after five dry-cleanings and machine washings. In addition to the required Europeanstandard, surface resistance was also measured at the following relative humidity:35, 45, 55 and 65per cent.The results were processed by the correlation analysis and shown graphically.
