A fiber composite having one or more layers of reinforcing fibers or filaments, that contains one or more layers of ribbon yarns brought into contact with it, as well as a method for its production.

Loose-fill insulating products include mineral wool, in particular glass wool or rock wool, in the form of down, nodules or flakes, which are obtained from a method including an aeration step that allows the mineral wool to be expanded.

Loose-fill insulating products include mineral wool, in particular glass wool or rock wool, in the form of down, nodules or flakes, which are obtained from a method including an aeration step that allows the mineral wool to be expanded.

A method for preparing an insulating product based on wool includes an aeration step inside a device, the device including a chamber and at least one structure capable of generating a turbulent gaseous flow, during the aeration step. A stream of carrier gas is introduced into the chamber and a wool in the form of nodules or flakes is subjected to the turbulent flow of this carrier gas with entrainment in one sense in a direction A and in the opposite sense in a direction B that is the opposite to the direction A so that within the chamber there is at least in one plane perpendicular to the direction A in which the wool entrained in the direction A crosses the wool entrained in the direction B.

A system and corresponding method are provided for controlling production in a blow room, the blow room including a controller, a supplying machine having a supplying part, and a machine to be supplied that has a filling level measurement. The supplying machine and the machine to be supplied are connected to the controller. A production area is defined for the supplying machine and includes a minimum production and a maximum production. Production of the supplying part of the supplying machine is determined based on a filling level of the filling level measurement. When production of the production area drops below the minimum production, the supplying part of the supplying machine is shut down, the shutdown taking place independently of the filling level of the machine to be supplied.

Cotton cleaner assembly with saw drum and releasable grid bar mechanism that includes bars and a release mechanism that moves the bars between operational and released positions is disclosed. In operational position, the release mechanism locks the bars in a fixed position relative to the saw drum to knock debris from cotton that rotates with the saw drum. In released position, the release mechanism moves the bars away from the saw drum to enable blockages that interfere with saw drum rotation to be cleared. The grid bar mechanism can include side members, where the bars extend between the side members, and the release mechanism moves the side members. The release mechanism can manually or hydraulically pivot the side members about pivot points against and away from stops. The pivot points and stops can be adjustable to adjust distance between the bars and saw drum in the operational position.

This application provides, at least in part, a fiber refining machine and a method of using the same. The fiber refining machine includes a fiber feeding assembly, a rotary brush assembly and a rotary cutter assembly. The fiber feeding assembly comprises a feeding nip formed between a rotatable roll a nose bar and configured to feed a fibrous material through the nip. The rotary brush assembly includes a wire wheel positionable downstream of the feeding nip and configurable to comb the fed fibrous material to remove connective tissue and/or resinous coating therefrom and to separate the combed fibrous material into individual fibers. The rotary cutter assembly includes at least one rotatable knife and a stationary anvil, the rotary cutter assembly configurable to receive and cut the separated individual fibers into predetermined lengths.

A method of manufacturing a cushioning material P includes a defibrating step of defibrating a cloth to produce fibers F in dry forming, a mixing step of mixing the fibers F with a bonding agent to produce a mixture, an accumulation step of accumulating the mixture in air to produce a web W, and a first forming step of pressurizing and heating the web W to form the web W.

A fireproof material used for a lithium battery module and a method for producing the same are provided. The fireproof material has a stacked structure formed by stacking multiple layers of mesh structures. Each layer of the mesh structures includes a plurality of first fibers and a plurality of second fibers. The first fibers are oxidized fibers, and the second fibers are silicate fibers. Each layer of the mesh structures is formed by interweaving the plurality of first fibers and the plurality of second fibers. The multiple layers of the mesh structures of the fireproof material have a stacked layer number of between 5 layers and 20 layers and a stacked layer thickness of between 0.3 mm and 5 mm. The fireproof material has a density of between 0.05 g/cm.sup.3 and 2 g/cm.sup.3 and a thermal conductivity of between 0.01 W/(m.Math.K) and 0.8 W/(m.Math.K).
