Method and apparatus for the production of nonwoven web materials |
摘要 |
The present invention provides a method of making a nonwoven web, the method including the steps of providing plurality of fibers and subjecting to a pneumatic 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. |
