A separation device includes: a material supply section that supplies a material containing a fiber; a defibrating section that defibrates the material supplied from the material supply section; a separation section that includes a rotating member, a suction portion, and a collection section, the rotating member having a first surface and a second surface that are in a front and back relationship, being at least partially composed of a mesh, and to which a defibrated material generated in the defibrating section is supplied onto the first surface, the suction portion being provided on a side of the second surface of the rotating member and sucking the defibrated material via the mesh to remove foreign matter, the collection section collecting the defibrated material from which the foreign matter on the first surface has been removed; a weight detection section that detects a weight of the material supplied by the material supply section; and a controller that controls an operation of the separation section based on a detection result of the weight detection section.

A method for manufacturing a cellulosic paper material (150) is described. The method comprises: i) providing (105) used textiles as starting material (101), wherein the used textiles comprise cellulose and non-cellulosic foreign matters (in particular synthetic plastics and/or metal oxides), ii) at least partially depleting (120) the non-cellulosic foreign matters from the cellulose, to provide a depleted starting material (110), and iii) forming (170) the cellulosic paper material (150) from the depleted starting material (110). Furthermore, a cellulosic paper material (150) made of recycled used textiles and a use of used textiles for providing a cellulosic paper material (150) are described.

The present invention relates to methods for processing plant and/or micro-organism derived cellulose materials into rheology/structuring agents. More in particular, the present invention relates to methods wherein plant and/or micro-organism derived cellulose material is co-processed with carboxycellulose. The methods of the present invention provide a variety of benefits, in terms of process efficiency and scalability as well as in relation to the properties of the materials that are obtainable using these methods. For instance, it has been found that (highly) concentrated products produced using the method of the invention are easily (re)dispersible in water and aqueous systems to regain much of the cellulose component's original rheological performance.

A raw material supply device includes a housing that stores an aggregate of small pieces, a discharge port through which the small pieces are discharged from an inside of the housing, a rotor provided in the housing and including a protruding portion, and a magnet provided on the discharge port or on a downstream side of the discharge port. In addition, it is preferable that the raw material supply device further include a passage route that communicates with the discharge port and through which the small pieces pass, in which at least one pair of the magnets is disposed on one side and the other side via the passage route.

The present invention relates to pulp molded products including seaweed by-products and methods for producing the same. According to the methods of the present invention, pulp molded products including seaweed by-products are produced using apple pomace and/or green tea pomace. The presence of seaweed as a biodegradable and eco-friendly material and the addition of apple pomace and/or green tea pomace allow the pulp molded products to have natural antibacterial and anti-insect functions.

Provided is a processing device which includes a fluffing section for fluffing fibers contained in a sheet-like material, the fibers being at least near a surface of the sheet-like material, and a particle supplying section for supplying particles having Mohs hardness of 2 to 5 to the fluffed fibers. In addition, in such processing device, the particle supplying section preferably has an ejecting portion for ejecting the particles.

A sheet manufacturing apparatus capable of suppressing adhesion of defibrated material to the inside of the apparatus is provided. A sheet manufacturing apparatus has a defibrating unit that defibrates into defibrated material feedstock containing fiber; mesh that captures at least part of the defibrated material conveyed from the defibrating unit by gas, and passes the gas; an opening to which the defibrated material captured by the mesh, and gas of a different state than the gas from the defibrating unit, are introduced; and a sheet forming unit that forms a sheet using the defibrated material introduced from the opening.

A method for producing an air-laid product or a non-woven product from a starting material includes: comminuting starting material into a comminuted material in at least one comminution line by at least one comminuting device; feeding the comminuted material into at least one material buffer; removing the comminuted material from the at least one material buffer; metering the comminuted material by at least one metering device; supplying the comminuted material to at least one processing line with at least one defibration system in which the comminuted material is defiberized into a defiberized material; and feeding the defiberized material into a production machine and processing the defiberized material into an air-laid product or a non-woven fabric. The at least one metering device is controlled in such a way that a continuous mass flow of defiberized material is supplied to the production machine.
