Abstract: Spunbonded nonwoven nylon fabrics are formed from a blend of nylon 6 and nylon 6,6 polymers. A blend or copolymer of 0.1 to 10 percent by weight of nylon 6, balance nylon 6,6 is extruded into continuous filaments, pneumatically attenuated and drawn, and deposited onto a collection surface forming a web. The web is bonded either chemically or thermally. The fabric exhibits improved filament bonding. The addition of nylon 6 also improves the spinning performance of a nylon 6,6 spunbonded nonwoven process.
