PROBLEM TO BE SOLVED: To obtain a non-slip sheet capable of flexibly deforming and bonding to complex curved surface by providing a pressure-sensitive adhesive layer on either one surface of a sheet obtained by applying porous polyurethane coating to mesh-like nonwoven fabric having large degree of freedom to deformation so as to fill the mesh. SOLUTION: This non-slip sheet is obtained by providing an acrylic pressure- sensitive adhesive layer on either surface of a sheet obtained by impregnating dimethylformamide solution of polyurethane into a mesh-like nonwoven fabric having 0.3-3 mm mesh opening formed by mixing polyester fiber with rayon fiber and entangling these fiber so as to pack the above mesh and charging the treated nonwoven fabric into non-solvent such as water to substitute a solvent with water, etc., solidifying the polyurethane resin and applying porous polyurethane coating forming many fine pores to the nonwoven fabric. |
