Abstract
A process of producing a uniform fiber dispersion involves the use of an in-line dispersing chamber to provide an average fiber dwell time of only about ten minutes and less. The chamber is provided with a plurality of weedless, nonthrusting impellers that generate regions of reduced pressure and flow disruptive turbulence of high intensity, the turbulence being of sufficient intensity to rapidly open fiber bundles and disperse the individual long fibers during said dwell time within said chamber. The process produces a machine-made light weight glass fiber web material of exceptionally uniform fiber distribution. The web is comprised of micron diameter glass fibers having a fiber length of about 1/4 inch or more and a basis weight of about 5-30 grams/square meter. The web material exhibits an isolated multi-fiber defect count of less than 10 per 100 square feet and a visually perceptible overall uniform fiber distribution essentially devoid of 'cloud effect' fiber density variations.
