Experimentell rangordning av antändligheten hos kläder som används av riskgrupper

- Abstract
- The purpose of this report is to find out which composition of fibres in clothes are the easiest to ignite when exposed to a smouldering fire (i.e. a cigarette). The end result of this report were several rankings concerning the ignitability of sweaters made of polar fleece, WCT-overalls, knitted cardigans (sweaters), dressing gowns (bathrobes) and sweatpants. Several conclusions could be made and one of them is that 100 % viscose and 100 % cotton should be avoided because of their propensity to ignite. The second conclusion was that mixtures of cotton/polyester and cotton/viscose should be avoided. Even thou cotton/polyester ignited fewer times it had an ignition time that were significantly shorter which makes it more dangerous. If a... (More)

Even thou cotton/polyester ignited fewer times it had an ignition time that were significantly shorter which makes it more dangerous. If a decision should be made a blend of cotton/viscose is preferred before cotton/polyester. A content of at least 5 % elastan (also called spandex and lycra) in cotton/elastan mixtures and cotton/polyester/elastan mixtures should be sought since these didn’t ignite. In general 100% polyester together with 100 % wool and 100 % silk were among the least dangerous materials since they did not ignite. A low weight (i.e. g/m2) of 100% cotton should be sought since the afterglow tend to decrease when the weight decreases. (Less)
