Abstract
Official abstract text for this publication.
According to one embodiment, a fiber sheet includes a plurality of fibers. The plurality of fibers are in a closely-adhered state. All of the following ( 1 ) to ( 3 ) are satisfied, where F 1 is a tensile strength in a first direction, and F 2 is a tensile strength in a second direction orthogonal to the first direction: ( 1 ) F 2 >F 1; ( 2 ) F 1 is 1 MPa or more; and ( 3 ) F 2 /F 1 is 2 or more.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for manufacturing a fiber sheet, comprising: forming a deposited body by depositing a fiber formed by electrospinning, the deposited body including the fiber pulled in one direction; supplying a liquid to the deposited body, the liquid being volatile; and drying the deposited body including the volatile liquid, and when the liquid volatilizes, a part of the fiber is pulled in one direction to be adhered linearly by capillary force. 2. The method for manufacturing the fiber sheet according to claim 1 , wherein the fiber includes 2 wt % or more of a bio-affinity material. 3. The method for manufacturing the fiber sheet according to claim 1 , wherein the volatile liquid includes alcohol. 4. The method for manufacturing the fiber sheet according to claim 1 , wherein the drying the deposited body includes a portion of the fiber being fused.
