FLOOR COVERING AND METHOD OF ITS MANUFACTURING Russian patent published in 2011 - IPC D06N7/00 B32B5/22 B32B5/00 B32B5/10 B32B5/28 B32B27/40 C08G18/08 

FIELD: textile, paper.

SUBSTANCE: covering includes a textile element of surface 2 and a layer 1, which on the surface and at least partially is connected to this textile element of the surface. The layer 1 contains a viscoelastic polymer foam. The textile element of the surface 2 has a module of elasticity, the value of which makes from ≥0.5 N/mm² to ≤2.5 N/mm². In the layer 1 the viscoelastic polymer foam has deposition hardness, the value of which at 40% of compression makes from ≥1 kPa to ≤10 kPa. In the layer 1 the viscoelastic polymer foam has hysteresis, the value of which at the deposition hardness determination of 40% makes ≥20% to ≤70%.

EFFECT: method of manufacturing includes a foaming operation of the back side of the textile element of surface with the help of a reaction mixture, forming a polymer foam of the layer.
