  • Method of forming web material
    Patent number: 4351683
    Abstract: A method of forming a resilient open fibrous web of inter-engaged coarse continuous kinky filaments, with one major surface of the web being flattened. The method involves extruding a bundle of filaments of a thermoplastic material, aligning the bundle so the filaments fall into a quench bath and upon a contact surface so as to provide differential quenching, and advancing the resulting web at a slower rate than the rate of extrusion.
