NON-WOVEN MATERIAL WITH FILLING WITH PARTICLES Russian patent published in 2012 - IPC H01M2/16 

FIELD: textiles, paper.

SUBSTANCE: canvas for separator is made on the basis of a nonwoven fabric comprising fibers and primary pores formed by these fibers, which at least partially is filled with particles and these particles at least partially fill the primary pores and form the areas filled with the particles. According to the invention, the layer can be designed and improved in such a way that it has a small thickness, high porosity and thermal stability. At that the particles in the filled areas form secondary pores, and the average particle diameter exceeds the average pore size for the majority of the secondary pores. After glasing the linen its smoothing occurs due to its most dense packing of particles in the primary pores of the fibrous material. The resulting fabric has a small thickness, has a high porosity, thermal stability in a wide temperature range and is cheap to manufacture, which is the technical result of the present invention.

EFFECT: fabric is suitable for use as a separator for accumulator batteries or condensers of large capacity with high specific energy.
