<p>This involves a fabric, used mainly for cleaning air, the industrial mass of air and liquids containing, in addition to solid particles of dirt, harmful additives, consisting of a flat filtrating-absorbing formation and possibly also of a flat single-layer or laminated filtrating-reinforcing formation. The filtrating-absorbing formation consists of a layer of synthetic fibres and a layer of bonded non-woven fabric of chemical fibres with a filling of the selected absorber. The single-layer filtration-reinforcing formation is created from synthetic fibre batting. The laminated filtration-reinforcing formation consists of synthetic fibre fabric and/or a layer of glass fibre and synthetic fibres batting and the fabric is reinforced by a number of bundled fibres located proportionally throughout the whole fabric and passing through the thickness of the fabric, at least one surface of which is fused together.</p> |
