Abstract: The present subject matter relates to systems, devices, and methods of enhancing carbon fiber dispersion in wet-laid nonwovens. A quantity of fibers is deposited in a medium, and each of one or more stirring elements is moved in a pattern to mechanically agitate the medium. In some embodiments, moving each of the one or more stirring elements includes moving the one or more stirring elements in complementary patterns to induce a chaotic advection current within the medium.

Abstract: A spunbonded nonwovens is made by first spinning thermoplastic continuous filaments and emitting them from a spinneret in a direction and then passing the filaments in the direction through a cooling chamber. Meanwhile cooling air is fed from respective manifolds flanking the chamber into the chamber to cool the filaments and the cooling air is guided into the manifolds through respective manifolds and through respective planar homogenizing elements each having a plurality of openings forming a free open surface area constituting 1 to 40% of the total surface area of the respective planar homogenizing element. The cooling air passes from the planar homogenizing element into the cooling chamber through a flow straightener.

Abstract: A dry forming plant is described which comprises at least one distribution unit having a fibre and air inlet. Such distribution unit is placed above a forming wire opposite to at least one vacuum box which is connected to a suction unit. The distribution unit has an open bottom for release of the fibre material onto the forming wire below the distribution unit. More rotating rollers having protruding spikes are provided in the distribution unit for covering the cross sectional area of the open bottom. The vacuum box is divided into at least three longitudinal zones in a direction transversal to the advance direction of the forming wire. Said longitudinal zones have upwardly orientated intakes arranged below the forming wire. The longitudinal zones are connected with the suction unit via an outlet. The outlet comprises first shut-off means for partly or totally closing the outlet. The first shut-off means are independently operable.

Abstract: An apparatus for making spunbonded nonwovens has a spinneret for emitting continuous thermoplastic filaments in a filament-travel direction, a cooling chamber downstream in the direction from the spinneret for cooling the spun filaments with cooling air, two manifolds on opposite sides of the cooling chamber opening transversely of the direction into the cooling chamber, and a respective conduit having a conduit cross-sectional area and connected to each manifold for feeding cooling air thereto. The conduit cross-sectional area increases toward the manifold to a manifold cross-sectional area, and manifold cross-sectional area is at least twice as large as the conduit cross-sectional area. At least one flow straightener is provided upstream from the cooling chamber in each manifold for orienting air flow in an air-flow direction, and at least one perforated planar homogenizing element is provided in each manifold for homogenizing the cooling air flow.

Abstract: The invention relates to a thermal insulation product based on mineral wool comprising mineral fibers, the product comprising two main faces and longitudinal and transverse edges perpendicular to the main faces, the product being characterized by the following orientation fractions: a longitudinal orientation fraction greater than or equal to 48 %, or even 50 %, along an angle of more or less 6° with respect to the plane of the main faces, when the mineral fibers are counted only in a longitudinal cross-section, and a mean orientation fraction greater than or equal to 40 %, or even 45 %, along an angle of more or less 6° with respect to the plane of the main faces, when the mineral fibers are counted both in a transverse cross-section and in a longitudinal cross-section. The invention allows the insulating power of a thermal insulation product based on mineral wool to be improved without increasing its thickness.

Abstract: A method of making mounting mats comprising the steps of: (i) supplying inorganic fibers through an inlet of a forming box having an open bottom positioned over a forming wire to form a mat of fibers on the forming wire, the forming box having rollers for breaking apart clumps of fibers and an endless belt screen; (ii) capturing clumps of fibers on the endless belt; (iii) conveying captured clumps of fibers on the endless belt so as to enable captured clumps to release from the belt and be broken apart by the rollers; (iv) transporting the mat of fibers out of the forming box by the forming wire; and (v) compressing and restraining the mat of fibers to thereby obtain a mounting mat having a desired thickness suitable for mounting a pollution control element in a pollution control device.
