Abstract
Official abstract text for this publication.
A method of forming a fiber body includes defibrating a raw material in air to provide fibers; depositing the fibers in air onto a belt; applying pressure to the deposited fibers to form a pressurized web; and applying a liquid containing an additive to two surfaces of the pressurized web.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of forming a fiber body, the method comprising: defibrating a raw material in air to provide fibers; depositing the fibers in air onto a belt; applying pressure to the deposited fibers to form a pressurized web; and applying a liquid containing an additive to two surfaces of the pressurized web. 2. The method according to claim 1 , further comprising heating the pressurized web to which the liquid is applied. 3. The method according to claim 1 , further comprising applying pressure to the pressurized web to which the liquid is applied. 4. The method according to claim 1 , further comprising cutting the pressurized web to which the liquid is applied. 5. The method according to claim 1 , wherein the step of depositing the fibers forms a web on the belt. 6. The method according to claim 1 , wherein the liquid is applied to the two surfaces of the pressurized web by spraying. 7. The method according to claim 1 , wherein the additive includes a water resistant agent. 8. The method according to claim 1 , wherein the belt is a mesh belt. 9. The method according to claim 1 , wherein the raw material is selected from the group consisting of paper, pulp, a pulp sheet, a non-woven cloth, a cloth, and a woven fabric. 10. The method according to claim 1 , wherein the depositing comprises applying suction to the deposited fibers through the belt. 11. The method according to claim 1 , wherein the defibrating is performed using a mill.
