  • Publication number: 20190309449
    Abstract: A woven/knitted fabric (1) has a plurality of ridges (6) formed along one direction, and each ridge (6) is constituted by a top (3) and side walls (4), (5) under the top (3). At least one of the top (3) and side walls (4), (5) is different in color from other two of them. At least part of the plurality of ridges (6) is arranged such that a distance L4 between the ridges (6) adjacent to each other is 0.2 to 2.5 mm. The ridges (6) are set so as to satisfy the following relations: Ratio Ra=(L2+L3)/L4=0.8 to 7.9; Ratio Rb=L1/(L2+L3)=0.4 to 1.6; Ratio Rc=L2/L3=0.2 to 0.9; and Ratio Rd=L1/L5=0.4 to 1.2, where L1 is a width of the top (3), L2 is a thickness of the top (3), L3 is a height of the side walls (4), (5), and L5 is a distance between wall surfaces of the side walls (4), (5).
