<p>The upper layer of a non-woven textile material containing at least two layers has in those places subjected to load, reinforcement which is at least partially incorporated into that layer, extends through some or all the thickness of the layer and is permanently bound to it. The reinforcement may be a thermosetting resin, a thermoplastic, a latex etc. and may be coloured to tone with the material. For textiles of thermoplastic materials, reinforcement may be accomplished by the fusion of the fibres and a supplementary layer of thermoplastic is generally added to compensate for the reduction in volume.</p> |
