Abstract
A non-woven product containing organic and/or mineral particles has a volume density less than 1 and has at least two layers of synthetic fibers or filaments superposed in the Z direction perpendicular to the XY plane of the product, having undergone at least one needling operation, where the non-woven product integrates particulate feedstocks of mineral and/or organic particles distributed in a monomodal or multimodal manner in the product and at least partially coated or encapsulated by binding material that can point-connect the filaments or fibers to one another. At least one population or fraction of organic and/or mineral particles, has a size such that:3×(√{square root over ()}), preferably 5×(√{square root over ()})where SMf corresponds to the mean cross-section of the fibers or filaments that form the layers, and v represents the mean individual volume of the organic or mineral particles.
