    摘要: Improvements to processes and equipment for the manufacture of nonwoven webs useful in numerous applications including personal care, protective apparel, and industrial products. The fiber and/or filaments used to form the nonwoven fabric are deposited on a forming surface in a controlled orientation using application of an electrostatic charge to the fibers and/or filaments in combination with directing them to an electrode deflector plate while under the influence of the charge. The plate may be made up of teeth with a separation and angle orientation that are selected in accordance with the desired arrangement of the fibers and/or filaments in the nonwoven web. As a result, properties of the web such as relative strengths in the machine direction and cross-machine direction can be controlled.

    摘要: The present invention provides continuous fiber nonwoven webs with high material formation uniformity and MD-to-CD balance of fiber directionality and material properties, as measured by a MD:CD tensile ratio of 1.2 or less, and desirably of about 1.0 or less, and laminates of the nonwoven webs. The invention also includes a method for forming the nonwoven webs wherein the fiber production apparatus is oriented at an angle less than 90 degrees to the MD direction and the fibers are subjected to deflection by a deflector oriented at an angle B with respect to the centerline of the fiber production apparatus where B is about 10 to about 80 degrees.
