Abstract

Official abstract text for this publication.

A sheet manufacturing method includes defibrating a defibration object into a defibrated material in the atmosphere, mixing, in the atmosphere, additive agents including resin into the defibrated material that has been defibrated, adding moisture to a mixture of the defibrated material and the additive agents after the mixing is completed, and heating the mixture that has been moisture-added.

First claim

Opening claim text (preview).

What is claimed is: 1. A sheet manufacturing method comprising: defibrating a defibration object into a defibrated material in the atmosphere; mixing, in the air, additive agents including resin into the defibrated material that has been defibrated; adding moisture to a mixture of the defibrated material and the additive agents after the mixing is completed; and heating the mixture that has been moisture-added, to form a sheet. 2. The sheet manufacturing method according to claim 1 , further comprising depositing the mixture at a depositing unit after the mixing, wherein the adding of the moisture includes adding the moisture to the mixture after the depositing. 3. The sheet manufacturing method according to claim 2 , wherein the depositing includes depositing the mixture on a mesh belt which the depositing unit includes, after the mixing. 4. The sheet manufacturing method according to claim 1 , further comprising pressing the mixture after the adding of the moisture and before the heating of the mixture. 5. The sheet manufacturing method according to claim 3 , wherein the pressing of the mixture includes pressing the mixture without fusing the resin, and the heating of the mixture includes heating the mixture to fuse the resin and bond the mixture. 6. The sheet manufacturing method according to claim 1 , wherein the adding of the moisture includes adding the moisture such that a moisture content of the mixture is in a range from 5 parts by weight to 12 parts by weight, with respect to 100 parts by weight of the mixture before the adding of the moisture. 7. The sheet manufacturing method according to claim 1 , wherein the adding of the moisture includes adding the moisture such that a moisture content after the adding of the mixture is greater than a moisture content included in the defibration object. 8. The sheet manufacturing method according to claim 1 ., wherein the adding of the moisture includes adding the moisture such that a moisture content given to the mixture is varied in accordance with at least one of conditions of a moisture content of the defibration object, humidity of the environment, and temperature.
