An adsorption filter material used especially for producing protective materials, such as NBC protective suits, has a first layer, a second layer, and an adsorption layer arranged between the first layer and the second layer. The adsorption layer has a first activated carbon layer with granular or spherical activated carbon particles. The first activated carbon layer additionally contains activated carbon fibers and/or the adsorption layer additionally contains a second activated carbon layer with activated carbon fibers.

A gas and water vapor pervious adsorption filter material having a protective function against biological and chemical noxiants and poisons and a multilayered layer construction including a first sheetlike carrier layer, a second sheetlike carrier layer and, interposed between the first carrier layer and the second carrier layer, an adsorbing layer, the adsorbing layer comprising an activated carbon fiber fabric which is durably adhered to the first carrier layer and to the second carrier layer by means of an adhesive.

A protective glove having a protective function against toxic chemical agents, especially chemical warfare agents, and a multilayer construction including a breathable layer is disclosed. The glove has a support layer and a barrier layer, which is assigned to the support layer and which faces the hand when the glove is worn, prevents or at least retards the passage of toxic chemical agents, and contains an adsorption layer based on an adsorbent material, such as activated carbon, which adsorbs toxic chemical agents. The barrier layer has, in addition to the adsorption layer, a membrane, which is at least preferably impermeable to water and air, but permeable to water vapor, and which retards the passage of toxic chemical agents or is at least essentially impermeable to toxic chemical agents. The membrane is arranged between the support layer and the adsorption layer. The protective glove has a high degree of wearing comfort with good tactility properties and at the same time provides excellent protection against toxic chemical agents.

The present invention relates to iodine demand disinfectants. It relates in particular to a process for preparing a polyiodide-resin for use as an iodine demand disinfectant wherein a porous strong base anion exchange resin in a salt form, is contacted with a material capable of donating a member absorbable by the resin so as to convert the resin to the polyiodide-resin. The adsorbable member is selected from the group comprising I.sub.2 and polyiodide ion having a valence of -1. The process is characterized in that conversion of the anion exchange resin to the polyiodide-resin is effected at elevated temperature and elevated pressure, the elevated temperature being 100 degrees C. or higher, the elevated pressure being greater than atmospheric pressure. The present invention also relates to disinfectant substance comprising an iodine (impregnated) resin as produced by the above process.
