SURFACE MATERIAL FOR ABSORBING ARTICLE

摘要

PURPOSE:To obtain the subject surface material having excellent properties to permeate liquid and prevent the return of liquid by specifying the areal ratio of a part positioned at the boundary between parts having different fiber densities and the liquid diffusion distances at the front and back surfaces of the material. CONSTITUTION:The area of the part C positioned at the boundary between a part A having relatively low fiber density and a part B having relatively high fiber density is made to be 2-50% of the total area of the surface material. The liquid diffusion distance x(mm) on the front surface contacting with skin and the liquid diffusion distance y(mm) on the back surface contacting with an absorbing material are selected to satisfy the formula x
