The object of the invention is a nonwoven product containing organic and / or mineral particles, and a method for its preparation. A soft non-woven product with a bulk density below 1, formed from at least two layers of synthetic fibers or threads, superimposed on each other in the Z direction, perpendicular to the XY plane of the specified product, which was subjected to at least one mechanical or hydraulic needle-piercing operation, wherein non-woven product also includes a special granular filler in the form of mineral and / or organic particles distributed mono- or multimodally in this product and for at least an hour typically coated or encapsulated with a binder that is capable of connecting, at least pointwise, the filaments or fibers to each other, the non-woven product being characterized in that at least one population or fraction of organic and / or mineral particles, called “coarse particles” , has a size such that, preferably, where SMf corresponds to the average cross section of the fibers or filaments forming the layers of the nonwoven product, av means an individual average volume of organic or mineral particles. |
