Abstract
Provided are a binder useful for making sheets processed to effectively prevent misfeeds, a sheet manufacturing apparatus capable of desirably manufacturing sheets processed to effectively prevent misfeeds, a sheet manufacturing method, and a sheet processed to effectively prevent misfeeds. The binder for binding fiber to make sheets includes resin; and polyhydric alcohol that is a solid at room temperature and changes to liquid phase when heated. The content of polyhydric alcohol to 100 parts by weight resin is greater than or equal to 0.1 parts by weight and less than or equal to 20 parts by weight polyhydric alcohol.
Claims13
A binder for binding fiber and making a sheet, comprising:
- resin;
- and
- polyhydric alcohol that is a solid at room temperature and changes to liquid phase when heated.
A sheet manufacturing apparatus comprising:
- a defibrator configured to defibrate material containing fiber;
- a binder supply device configured to supply binder to the defibrated material defibrated by the defibrator;
- and
- a heater configured to heat the defibrated material to which the binder was added;
- the binder containing resin, and polyhydric alcohol that is a solid at room temperature and changes to liquid phase when heated.
A sheet manufacturing method comprising:
- a defibrating step of defibrating material containing fiber;
- a binder supply step of supplying binder to the defibrated material defibrated in the defibrating step;
- and
- a heating step of heating the defibrated material to which the binder was added;
- the binder containing resin, and polyhydric alcohol that is a solid at room temperature and changes to liquid phase when heated;
- and
- the polyhydric alcohol contained in the binder changing to liquid phase during heating in the heating step.
A sheet made of fibers bonded by a binder, wherein:
- the binder contains resin, and polyhydric alcohol that is a solid at room temperature and changes to liquid phase when heated.
