摘要 |
A process for the manufacture of a stiff permeable sheet-like fibrous structure which includes forming a web with 20% to 60% single fibres having a high modulus of elasticity (as herein defined) and between 7 and 50 millimetres long, and 40% to 60% by weight of a wholly or substantially unconsolidated particulate plastics material, and then treating the web by heating to melt the plastics material and passing it between a pair of nip rollers (21, 22, 23, 24) so that the plastics material can flow and wet out the fibres, the nip between the rollers being set to a dimension less than the thickness of the unconsolidated web and greater than that of the web if it were to be fully consolidated, and allowing the web to expand and remain substantially permeable after passing through the rollers. |
