In the fighting of fires or protection of objects from fire by applying thereto water, the improvement which comprises dispersing in the water particles of a cross-linked water-insoluble but hightly water-swellable acrylic acid derivative polymer in an amount insufficient to bring the viscosity above 100 mPa's. Advantageously, the particles are present in an amount such that after swelling the swollen particles hold 60 to 70% by weight of the total water, the particles are from 0.1 to 3 mm in diameter and are present in from 0.1 to 0.6% by weight of the water, the polymer being a copolymer of an acrylic acid, the water containing silicic acid and/or a silicate as well as sodium, potassium or ammonium ions. The water is freely pumpable but the swollen particles adhere to surfaces they contact rather than running off rapidly.

A sheet filter made up of a flat textile article carrying micrometric particles of a resistant and/or adsorptive additive, the textile article made up of fibers which upon heating become temporarily adhesive without fusing. Advantageously the textile article is a nonwoven fibrous fleece or a pile fabric; if a fleece, a second fleece can be placed over the additive particles so heating unites the fleeces as well as adhereing the particles.

The present invention involves an inner shoe material with adsorbent properties, whereby activated carbon particles are fixed as the adsorbent material by means of an adhesive substance in a punctiform manner to the side of the material facing away from the foot. The inner shoe material of the invention can be designed as inside lining, insoles, slipsoles, as inner sole of the shoe or as a covering material for the inner sole of the shoe. The inner shoe material of the invention can e.g. be used for combat boots with integrated C-protection or for safety boots with protection against aggressive chemicals. The inner shoe material has the advantage that it exhibits a high degree of scuff resistance on the one hand and the adsorbent activated carbon is freely accessible to the substances to be adsorbed, on the other.
