Abstract
A sheet manufacturing method includes a web forming step of forming a web by accumulating a defibrated product in a dry manner, a moisture imparting step of imparting the web with moisture, a pressurizing step of pressurizing the web to which the moisture is imparted, and a heating step of heating the web to which the moisture is imparted, in which a water content of the web to which the moisture is imparted in the moisture imparting step is 12% by mass or more, a pressure applied to the web in the pressurizing step is 0.2 MPa or more, and a temperature of the web in the heating step is 100° C. or lower.
Claims8
A sheet manufacturing method comprising:
- a web forming step of forming a web by accumulating a defibrated product in a dry manner;
- a moisture imparting step of imparting the web with moisture;
- a pressurizing step of pressurizing the web to which the moisture is imparted;
- and
- a heating step of heating the web to which the moisture is imparted, wherein
- a water content of the web to which the moisture is imparted in the moisture imparting step is 12% by mass or more,
- a pressure applied to the web in the pressurizing step is 0.2 MPa or more, and a temperature of the web in the heating step is 100° C. or lower.
A sheet manufacturing apparatus comprising:
- a belt on which a defibrated product is accumulated in a dry manner to form a web;
- a moisture imparting portion that imparts moisture to the web;
- a pressurizing portion that is arranged downstream of the moisture imparting portion and that pressurizes the web to which the moisture is imparted;
- and
- a heating portion that is arranged downstream of the moisture imparting portion and that heats the web to which the moisture is imparted, wherein
- a water content of the web to which the moisture is imparted in the moisture imparting portion is 12% by mass or more,
- a pressure applied to the web in the pressurizing portion is 0.2 MPa or more, and
- a temperature of the web in the heating portion is 100° C. or lower.
