Abstract
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.
Claims48
A processing device comprising:
- a fluffing section that fluffs 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 that supplies particles having Mohs hardness of 2 to 5 to the fluffed fibers.
A processing device comprising:
- a fluffing section that fluffs fibers contained in a sheet-like material, the fibers being at least near a surface of the sheet-like material;
- and
- an alien substance-removing section that removes alien substances contained in the sheet-like material by bringing the fluffed fibers into contact with a fabric material formed of a nonwoven fabric or a woven fabric so that the alien substances migrate to the fabric material.
A processing method comprising:
- fluffing fibers contained in a sheet-like material, the fibers being at least near a surface of the sheet-like material;
- and
- supplying particles having Mohs hardness of 2 to 5 to the fluffed fibers.
A manufacturing method of a sheet, comprising:
- fluffing fibers contained in a sheet-like material, the fibers being at least near a surface of the sheet-like material;
- and
- supplying particles having Mohs hardness of 2 to 5 to the fluffed fibers,
- wherein the sheet is manufactured from the sheet-like material after the particles are supplied.
