  • Process and apparatus for increasing the isotropy in nonwoven fabrics
    Patent number: 6877196
    Abstract: A method for changing the position of fibers in a nonwoven web to improve the isotropy of the web by using angled stream of fluid wherein the streams form a substantially coplanar curtain and impinge on the fibers at their leading ends, trailing ends or sides.
    Type: Grant
    Filed: August 3, 2001
    Date of Patent: April 12, 2005
    Assignee: E. I. du Pont de Nemours and Company

  • Inlet design for handling bulk textile fiber
    Patent number: 6317932
    Abstract: The invention is particularly related to the problems of dispersing fiber to obtain a uniform distribution. The invention includes tapered ducts oriented at an appropriate angle relative to the horizontal for redirecting and decreasing the speed of an air stream containing fiber therein such that the fiber precipitates from the air stream and falls gently to form a uniform fiber bed in a bin.

  • Acceleration arrangement for airlay textile web formers
    Patent number: 5564630
    Abstract: This invention relates to an improved air acceleration nozzle for use in airlay web formers which reduce the creation of large scale vortices and turbulence. The nozzle accelerates the air by reducing the cross sectional area of the conduit. The size of the conduit for the air is reduced in both lateral dimensions, and more preferably, both dimensions are reduced with smoothly curving, low angle peripheral walls.
