<p>A leather or leather substitute laminate is made by bonding together a first layer of leather or leather substitute material and a second layer of woven synthetic or part synthetic material, for example Lycra® spun elastomeric fibre, with the layers having anisotropic elasticity property and arranged such that the axis or axes of minimum modulus of elasticity in the first layer extend at an angle of 45° or less to that or those in the second layer. The elastic modulus and the elastic power of the second layer may be selected so that is high enough for the second layer to reverse at least a major part of the non-elastic portion of the leather extension on relaxation thereof.</p> |
