Abstract
Described herein are 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. The charging of the pins is controlled so that not all pins remain at maximum charge during a cycle with the result that extended run times may be obtained.
