A system that receives nanomaterials, forms nanofibrous materials therefrom, and collects these nanofibrous materials for subsequent applications. The system is coupled to a chamber that generates nanomaterials, typically carbon nanotubes produced from chemical vapor deposition, and includes a mechanism for spinning the nanotubes into yarns or tows. Alternatively, the system includes a mechanism for forming non-woven sheets from the nanotubes. The system also includes components for collecting the formed nanofibrous materials. Methods for forming and collecting the nanofibrous materials are also provided.

A leather substrate formed from waste leather and its method of production, particularly a leather substrate made up substantially of a collagen fibril matrix.

A fiber material accumulating apparatus which includes a storage section including a porous screen, a supply section which supplies a material containing fibers to the storage section, and a rotating body which is provided inside the storage section and includes a blade which rotates to agitate the material, in which the blade includes an extending portion extending along a rotational axis of the rotating body, and an opening through which the material passes when the blade rotates.

A process for producing a deformed nonwoven is described. The process includes the steps of: adjusting a water content of a nonwoven such that the nonwoven has at least one area having a water content of at least about 12% by weight of the nonwoven in the area, and subjecting the nonwoven to a mechanical deformation process. The deformation process is a mechanical deformation of the nonwoven and dewatering of the nonwoven to obtain a deformed nonwoven.

A system and associated method for preparing a composite sheet material is provided. The system includes a nonwoven fabric source; a collection surface onto which a nonwoven fabric is deposited; a carding device disposed downstream of the nonwoven fabric source overlying the collection surface, the carding device including a main cylinder, an air source configured to provide a stream of air; an air manifold having an air inlet in communication with the air source, an air outlet, a fiber inlet, an interior channel, and a fiber outlet. The air outlet is positioned to direct an air stream against a surface the cylinder to dislodge fibers from the surface of the cylinder. The dislodged fibers enter the fiber inlet and flow to the fiber outlet at which point the fibers are deposited onto a surface of the nonwoven fabric. The fabrics are then bonded to form a coherent sheet material.

A wipe comprises upper and lower melt-blown fiber webs and an intermediate wood pulp fiber web containing a hot-melt adhesive substance. Melt-blown fibers of the melt-blown fiber webs are interwoven in the wood pulp fiber web. A manufacturing method of a wipe can manufacture a water-absorbing wipe, effectively prevent the wipe from shedding fibers when in use, and effectively prevent agglomeration of short wood pulp fibers after the wipe has absorbed a liquid.

An apparatus and method for opening lumps and tuffs of fibre material in blow room of a spinning facility is disclosed. The disclosed method and apparatus use bursts of pressurized gaseous fluid which results in better opening of fibre lumps and reduced damage or breakage of the fibres. The gaseous fluid may be air or a gas or a mixture of air and gases. One or more nozzles 206 arranged in one or more rows are used to direct one or more controlled jets of a pressurized gaseous fluid at the tuffs/lumps 210 of fibre material entering through an opening 204 of at least one chamber 202, which results in opening of the tuffs to smaller and more opened tufts of fibre as well as in separation of foreign material trapped in the lumps. The controlled jets of the pressurized gaseous fluid, such as air, may be bursts of short durations.
