ABSTRACT:
A method of producing needlework canvas materials which are flexible, non-distortable composite laminated materials having a primary layer of non-elastic, open-mesh woven needlework fabric which has welded or bonded to one of its faces a relatively thin non-elastic secondary mesh-stabilizing layer of synthetic fiber sheer fabric material. The sheer fabric secondary layer is bonded to the open-mesh primary layer by the application of ultrasonic vibrations and pressure to interfaced moving webs of the primary and secondary fabric materials. The ultrasonic vibratory energy, applied to the interfaced webs, results in the creation of intermolecular mechanical stress with causes heating and melting of the thermoplastic or synthetic materials of the woven primary layer and the synthetic fiber material of the secondary layer. The thus melted thermoplastic material and synthetic fiber material co-mingle with bonding of the layers at a multiplicity of pressure points of contact of the threads of the primary layer with the fibers of the secondary layer, where intermolectular stress is maximized.
