PROBLEM TO BE SOLVED: To provide a shading sheet having high strength and excellent softness, and excellent in workability, handleability and shading property. SOLUTION: (1) The shading sheet consisting of a sheet produced by pressing and bonding partly nonwoven fabric of polyester yarn containing a coloring pigment, and having a unit area weight of 70-200 g/m2, a pulling strength ratio of the lateral direction and the longitudinal direction (the longitudinal direction/ the lateral direction) of 0.5-2.5 and a shading percentage of >=95%. (2) The shading sheet in which the average fiber diameter of the nonwoven fabric is 6-30 μm. (3) The shading sheet in which the area of pressing and bonding partially the nonwoven fabric is 3-25% the total area of the nonwoven fabric. (4) The shading sheet in which the content of the coloring pigment in the polyester yarn is 0.1-5 wt.%. (5) The shading sheet in which the average apparent density of the nonwoven fabric is 0.1-0.3 g/cm3. (6) The shading sheet in which the water absorbing speed of the shading sheet is less than 10 sec. |
