| 摘要 |
The invention relates to the forming of felts, the fibres of which are disposed in random directions. These felts are obtained by depositing the fibres which are carried by a current of gas on a gas-permeable conveyor, the fibres, prior to being deposited, being coated with a binder composition. The felt constituted on the conveyor is subject to at least a longitudinal compression, the intensity of which is regulated in such a way that no creases form on the surface. The felts obtained are highly resistant to compression, to tearing and to flexion. |
