<p>A process for producing a non-woven fabric and fabric produced thereby, the process comprising (1) forming a stack of three or more superimposed fibrous shims, in at least one of the shims the fibres being oriented predominantly in a first direction, corresponding to the machine direction of the shim, and in at least one of the other shims the fibres being oriented predominantly in a second direction, corresponding to the machine direction of the shim, which is inclined at an acute angle to an imaginary line which is orthogonal to the first direction, and in at least one of the other shims the fibres being oriented in a third direction, corresponding to the machine direction of the shim, which is inclined at an obtuse angle to an imaginary line which is orthogonal to the first direction, (2) bonding the fibrous shims together, (3) subjecting the bonded fabric so formed to a stentered operation in a direction orthogonal to the first direction which causes the bonded shims to expand orthogonally to the first direction and to contract in the first direction, and (4) heat setting the bonded shims while they are being stentered.</p> |
