Composite nonwoven fabric and method

摘要

A composite nonwoven fabric and method for making the same includes subjecting a carded web to the action of a cross lapper (B) and then drafting the cross-lapped web by passing the same through a web drafter (C) utilizing a series of wire wound rolls of progressively increased speed. A web of substantially unbonded polymeric fibers is layed from a roll (D) forming a composite web by hydroentanglement utilizing a series of spun bonding steps resulting in a composite web of substantial strength comparison in the machine direction and in cross direction and possessing the characteristics of fabric suitable for use in hospital applications such as surgical gowns.
