The present invention provides a method of making a nonwoven web, the method including the steps of providing plurality of fibers and subjecting the fibers to a pneumatic attenuation force which imparts a velocity to the fibers, reducing the velocity of the fibers in a diffusion chamber which is formed substantially between opposed diverging sidewalls, subjecting the fibers to an applied electrostatic charge, and thereafter collecting the fibers into a web on a moving forming surface. The invention also provides an apparatus for forming nonwoven webs, the apparatus comprising a source of fibers, a fiber attenuation chamber, a diffusion chamber formed substantially between opposed diverging sidewalls, the diffusion chamber located below the fiber attenuation chamber, and a forming surface for collecting the fibers as a nonwoven web.

Method for the production of nonwoven web materials

A method of producing a laminate material includes the steps of providing a first flexible sheet material; providing a second flexible sheet material having a first surface and a second surface, and also having a first width of 1&#xd7;; stretching the second flexible sheet material in a cross-machine direction to a second width of between about 1.2&#xd7; and 3&#xd7; when in a flattened state; necking the second flexible sheet material to produce an accordion shape, thereby reducing the second width of the sheet material to a third width, less than the width of the first width, such that the third width is between 0.65&#xd7; to 0.975&#xd7; when in an accordion shape; applying adhesive to the first surface of the second flexible sheet material with a slot coat adhesive process; and joining the first flexible sheet material to the first surface of the second flexible sheet material.

The present invention provides a method of making a nonwoven web with desired fiber orientation, the method including the steps of providing a source of fibers, subjecting the fibers to an electrostatic charge, deflecting the fibers with a non-contacting deflecting device, collecting the fibers on a moving forming surface to form the nonwoven web. The invention also provides an apparatus for forming fibrous nonwoven webs, the apparatus comprising a source of fibers, a device for applying an electrostatic charge to the fibers, a non-contacting fiber deflecting device adapted to affect the fibers while the fibers are under the influence of the applied electrostatic charge, and a forming surface for collecting the fibers as a fibrous nonwoven web.
