| 摘要 |
The invention relates to a method for obtaining non-woven fabrics with acoustic, thermal and filtering properties, said fabrics being obtained using a mechanical method of carding or hydroforming and strengthened by hydroentangling or needlepunching, being optionally reinforced with a polymer resin. The method is characterised by the use of a novel mixture of fibres of different deniers between 0.01 and 30, inclusive, as well as fibres that can be of synthetic, natural and/or mineral origin, for acoustic, thermal, filtering, comfort and cleaning uses in various markets. |
