Abstract

Non-woven fabrics mfr in which the entanglement of extruded filaments in a non-woven array is enhanced by folding and superimposing thin layers prior to needle treatment. The mat may also be calendered, before or after folding. Esp. for treating filaments comprising homo- or copolymers of polyolefins, polyamides, polyester, vinyl and/or acrylic resins, esp. isotactic polypropylene or polyamide-6. Results in greater degree of mutual entanglement and hence enhanced strength, extensibility and water resistance than needle treatment of a single layer of thick mat.
