PROBLEM TO BE SOLVED: To provide a high stress sheet that is excellent in elastic property and self-adhesion property, safe and excellent in hand tearability.SOLUTION: The high stress sheet is made of a nonwoven fabric 1 comprising 80 mass% or more of crimped fibers having an average radius of curvature of 50 to 200 μm and composed of at least two components including a polyester resin comprising dicarboxylic acid components in which 75 mol% or more is a terephthalic acid and/or an ester-forming derivative thereof and copolymerization components including a compound (i) represented by a specific formula, and further a cyclohexanedicarboxylic acid and/or an ester-forming derivative thereof as (ii), and an aliphatic acid and an ester-forming derivative thereof as (iii). The nonwoven fabric satisfies the following physical properties in at least one direction: a) the breaking strength is 5 to 30 N/50 mm; b) the breaking elongation is 50% or greater; c) the stress at 25% recovery after 50% elongation is 0.8 N/50 mm or greater; and d) the curved surface sliding stress is 0.5 N/50 mm or greater. |
