Abstract
Official abstract text for this publication.
A fiber assembly-forming method includes forming a web containing a plurality of fibers charged to a first polarity on a transport belt charged to a second polarity opposite to the first polarity and applying a liquid to the web formed on the transport belt from a nozzle of a liquid coater. The liquid contains a binder binding the fibers.
First claim
Opening claim text (preview).
What is claimed is: 1. A fiber assembly-forming apparatus comprising: a transport belt on which a web containing a plurality of fibers charged to a first polarity is formed, the transport belt being charged to a second polarity opposite to the first polarity; and a liquid coater applying a liquid to the web formed on the transport belt from a nozzle, wherein the liquid contains a binder binding the fibers. 2. The fiber assembly-forming apparatus according to claim 1 , wherein the liquid contains water and the water fraction of the web coated with the liquid is 15.0% or more. 3. The fiber assembly-forming apparatus according to claim 2 , wherein the water fraction is 17.7% to 35.0%. 4. The fiber assembly-forming apparatus according to claim 1 , further comprising: a disintegration section disintegrating a feedstock containing a plurality of fibers; and a deposition section depositing disintegrated matter obtained by disintegrating the feedstock on the transport belt to form the web on the transport belt. 5. The fiber assembly-forming apparatus according to claim 1 , further comprising a charge enhancement section enhancing the charge of the fibers contained in the web formed on the transport belt. 6. The fiber assembly-forming apparatus according to claim 1 , further comprising a pressurizing portion pressurizing the web formed on the transport belt before the liquid is applied to the web, wherein the pressurizing portion includes a first calender roller in contact with the web and a second calender roller in contact with the transport belt, the first calender roller is charged to the first polarity, and the second calender roller is grounded. 7. The fiber assembly-forming apparatus according to claim 1 , wherein the liquid coater is an ink jet head. 8. The fiber assembly-forming apparatus according to claim 1 , further comprising a charging section that charges the transport belt to the second polarity.
