Abstract

A low fluid pressure dual-sided fiber entangling method and apparatus for manufacturing a nonwoven fabric.
A fibrous starting material whose individual fibers are capable of movement relatively to one another under the influence of applied fluid forces is subjected to coacting opposed fluid streams while being confined between a flexible screen belt and a rigid perforated hollow drum.
The fibers of the starting material are entangled under the effect of fluid forces applied in opposition, forming a reticular network which defines a pattern of blind holes, each hole extending transversely to the fabric plane and containing a protuberant fiber packing at a closed end thereof.
