When this covering layer of a material subjected to varovanie.

The disadvantage of this material is its low thermal insulation properties, which is caused by low volume, caused by the use of tufting threads for mechanical bonding of the layers of material together. In addition, the sewed thread create in the material of the through-hole, which causes the need for additional operations rising to its top layer to close these holes and provide the protective function of the material. The task of what vaistai with simultaneous high sorption capacity with respect to the products of skin breathing and aggressive emissions and allocations.

This technical result according to the first embodiment of the invention is achieved due to the fact that non-woven layered protective material comprising one or more fibrous layers containing synthetic fibers, and absorbent layer carbon-reinforced paper, mechanically fastened together, the fibrous layer or layers made of a mixture of polyester fibers, comprising a hollow polyester fiber, at a ratio by weight within 3:7-7:3, carbon-reinforced paper is made of cellulose-based and coal, at a ratio by weight within 8:2-9:1 and is located on one of the outer sides of the material or between the fibrous layers, and all layers of material bonded together by hypoproteinemia.

In the carbon-reinforced paper used activated charcoal type.

According to another variant of the invention the specified technical result is achieved due to the fact that non-woven layered protective material comprising one or more fibrous layers containing synthetic fibers, and absorbent layer carbon-reinforced paper, mechanically fastened together, in which the fibrous layer or layers made of a mixture of hollow polyester Lana based pulp and coal at a ratio by weight within 8:2-9:1 and is located on one of the outer sides of the material or between the fibrous layers, all of the layers of material bonded together by hypoproteinemia.

To impart flame-retardant properties of the material under this option may be impregnated with a fire retardant composition based flame retardant.

In the carbon-reinforced paper used activated charcoal type.
