AN EMBOSSED COMPOSITE NONWOVEN WEB MATERIAL

摘要

An embossed composite nonwoven web material includes a mixture of thermally unbonded continuous spunlaid filaments and short fibers including natural and/or synthetic fibers or staple fibers. The continuous filaments and short fibers being substantially mechanically bonded to each other by hydroentangling and the composite nonwoven web material being embossed without thermobonds to have a strength index equal to or more than 1 time the strength index of the unembossed composite nonwoven web material.

1. A method for manufacturing a composite nonwoven web material, comprising:
extruding continuous polylactic acid (PLA) filaments from a spinnerette; drawing the filaments by a slot attenuation unit to thin continuous filaments; forming a web of unbonded continuous filaments without thermobonds; hydro entangling the web comprising continuous spunlaid PLA filaments together with wet or foam formed short fibers comprising natural and/or synthetic fibers or staple fibers to integrate and mechanically bond and form a thermally unbonded composite nonwoven web material; and drying the web material, wherein the composite nonwoven web material is embossed without forming thermobonds giving the web material a strength index equal to or more than 1 times the strength index of the unembossed composite web material.
