ABSTRACT:
There is provided a fabric which has been produced in a pneumatic chamber which has tiny grooves over an effective amount of its fluid contacting surface. Also provided is a method of producing a web having greater uniformity by producing it with pneumatic chambers having surface grooves. Fabrics produced in such a manner have greater uniformity when measured by permeability, basis weight or CD and MD strength properties.
