An apparatus suitable for separating particles and methods for using such apparatus are provided.

The present invention relates to leather fibers for product materials, physically extracted from cowhide, and more specifically, the leather fibers are easily obtained for each length so that there is an advantage in that the leather fibers having different lengths can be respectively used as materials more appropriately for various articles such as leather sheets or yarns.

A method for reclaiming fibers from a textile made of cellulose/synthetic fiber blend, comprising adding the textile to a solution comprising molten salt hydrate (MSH) and an acid catalyst to form a reaction mixture in which cellulose fibers are fibrillated and depolymerized, terminating the reaction to obtain fibrillated and depolymerized cellulose, recovering the cellulose from the re-action mixture, and recovering the synthetic fiber.

A recycled sheet generation system includes a detection section that detects a type of material included in a raw material, a fiber separation section that generates fibers by separating the raw material, a sheet production section that produces a sheet by depositing a mixture in which a treatment agent is mixed with the fibers generated by the fiber separation section, a printing section that prints on the sheet, a history acquisition section configured to acquire, as history, a sheet configuration component based on the type of material that is included in the raw material and that was detected by the detection section and a sheet production condition, and a registration section that registers the sheet configuration component and the sheet production condition in association with each other. The printing section prints an access destination for accessing the registered sheet configuration component and the sheet production condition in a predetermined region of the sheet.
