摘要： Disclosed is an improved high sorbency nonwoven fabric and its use particularly as an oilsorb material. The high sorbency nonwoven is preferably made by multi-bank meltblowing and different perturbing thermoplastic fibers of, for example, propylene polymers in separate banks to provide a fiber density gradient through the thickness of the fabric. The sorbent nonwovens have high bulk and strength, oil capacity and oil absorption rates making them particularly suited to such applications. Treatments and additives for such materials are also disclosed.

摘要： There is provided a high speed rotary valve which is relatively simple in design and which can effectively regulate the flow of fluid under high temperature conditions in such a manner as to produce perturbations in the fluid stream. Such a valve may be used to regulate the flow of fluid, e.g. air, toward a work piece to produce a perturbation in the piece for example. The clearance between the rotor and stator is such that the flow of fluid is never completely cut off, i.e., the valve continues to "leak through" the closed outlet port even when the rotor and stator openings are not aligned. Fluids having temperatures in the range of 40 to at least 900.degree. F. may be processed through this valve. The valve is also useful in creating aerosols of liquids and gases and in producing blown fibers.

摘要： An apparatus and method for increasing the heating efficiency of a nonwoven web using heated air are provided. A flow modifier including a turbulence inducing bar arrangement is positioned between the heated air supply and the nonwoven web. The flow modifier increases the turbulence of the heated air before it contacts the nonwoven web, resulting in more thorough penetration of the web by the air, and better convective heat transfer between the heated air and the nonwoven web.

摘要： 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.
