Composite nonwoven fabric and method of making same

The invention relates to a composite non-woven fabric (10), comprising: A substantially continuous heat by spinning is) and non-woven grid of the fibre is (11); Modelled is a grid material according the fibre composed of for (14); The non-woven fabric is of the modelled melt-blown microfibres is composed of for (13); there between the spinning substantially continuous fibre non-woven grid and heat of adhesive and non-woven grids. A binder (12) donation between the spunbond fibre non-woven filter net (11) and melt blown microfibre the non-woven grid (13), and heat and non-woven grid (14) and melt blown microfibre the non-woven fabric is between (13), wherein the non-woven filter net is bondings composite non-woven fabric. The 6-15mm embodiment, the composite non-woven fabric of the invention comprises: Non-woven grid of the substantially continuous nylon fibre by spinning is), and a polyamide non-woven grid, and a grid material according the micro of which is polyethylene is formed, wherein there between the spinning substantially continuous fibre non-woven grid and fibre non-woven fabric grids.
