By controlling the optical anisotropy of a fiber, a high contrast can be obtained regardless of the viewing angle, and a non-woven fabric and a composite material having high transparency, excellent heat resistance, and a small linear expansion coefficient can be obtained. thing. SOLUTION: Controlling optical anisotropy having at least one ring structure among aromatic compounds such as phenyl groups, naphthyl groups, biphenyl groups, and alicyclic compounds in fibers (a) containing hydroxyl groups such as cellulose fibers. The nonwoven fabric which consists of a modified fiber (c) which introduce | transduced the compound (b) to perform. [Selection figure] None |
