Abstract
A composite integrally includes a resin and a coagulation inhibitor, and is used to be mixed with fibers. The composite is a powder whose volume average particle diameter is 1 μm or more to 100 μm or less, and at least a portion of the coagulation inhibitor is arranged in a surface of the composite.
Claims15
A composite integrally including a resin and a coagulation inhibitor, and used to be mixed with fibers, the composite being a powder whose volume average particle diameter is 1 μm or more to 100 μm or less, at least a portion of the coagulation inhibitor being arranged in a surface of the composite.
A composite used in a sheet manufacturing apparatus and integrally including a resin and a coagulation inhibitor, the composite being a powder whose volume average particle diameter is 1 μm or more to 100 μm or less, at least a portion of the coagulation inhibitor being arranged in a surface of the composite.
A composite manufacturing method comprising:
- a step of mixing a resin and a coloring material;
- a step of kneading the resin and the coloring material to form a mixture of the resin and the coloring material;
- a step of pelletizing the mixture to obtain a pellet after the step of kneading;
- a step of crushing the pellet to obtain a crushed material being a powder whose volume average particle diameter is 1 μm or more to 100 μm or less;
- and
- a step of mixing the crushed material and a coagulation inhibitor to obtain a composite integrally including the resin, the coloring material and the coagulation inhibitor, at least a portion of the coagulation inhibitor being arranged in a surface of the composite.
A sheet comprising:
- a raw material including fibers and a composite integrally including a resin and a coagulation inhibitor, the composite being a powder whose volume average particle diameter is 1 μm or more to 100 μm or less, at least a portion of the coagulation inhibitor being arranged in a surface of the composite,
- wherein the fibers and the composite are bonded.
