<p>A material for protection against chemicals and short-term heating effects is made up of an air-permeable flexible base or support layer for adsorber particles, more specially, porous ones, which are placed on support columns or hairs on at least one side of the support layer. In a process for making the material, the adhesive composition is put on to the base or support material at separate points or dots in a viscous form and then the adsorber grains are placed on top of the composition. Then, by the action of centrifugal force or otherwise, the adsorber grains are moved upwards, away from the support layer, pulling out hairs or columns of the adhesive composition, which are then changed into a solid condition.</p> |
