Abstract (en)

[origin: DE19732927A1] In order to develop a garment for a cleanroom, capable of absorbing not only particles but also gas emitted by human beings and which interferes with obtaining an extra-pure atmosphere inside a cleanroom, it is suggested that, in addition to the airy medium for filtering particles, an adsorption layer of activated carbon be applied onto the side opposite the support. Said activated carbon is sheet material of activated carbon fibres. In order to fully remove ammonia also, the layer for filtering particles is impregnated preferably with a non volatile organic acid characterized by a good tolerance from a physiological point of view, for example citric acid.
