Abstract
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 F1 is a tensile strength in a first direction, and F2 is a tensile strength in a second direction orthogonal to the first direction: (1) F2>F1; (2) F1 is 1 MPa or more; and (3) F2/F1 is 2 or more.
Claims4
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.
