Title
(EN) SPUNBONDED NONWOVEN NYLON FABRICS
(FR) ETOFFES NON TISSEES EN NYLON FILE-LIE
Abstract
(EN)
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 fabrics exhibits improved filament bonding. The addition of nylon 6 also improves the spining performance of a nylon 6,6 spunbonded nonwoven process.
(FR)
On forme des étoffes non tissées en nylon filé-lié à partir d'un mélange des polymères que sont le nylon 6 et le nylon 66. Un mélange ou un copolymère à 0,1 - 10 pour-cent en poids de nylon 6, le restant étant du nylon 66, est extrudé en filaments continus, qui sont étirés et amincis pneumatiquement, puis déposés sur une surface de réception, pour former une étoffe. L'étoffe est consolidée chimiquement ou thermiquement. L'adhésion des filaments de l'étoffe est améliorée. Egalement, l'addition de nylon 6 améliore l'efficacité du filage du nylon 66 lors de la fabrication d'une étoffe non tissée en nylon filé-lié.
