COMPOSITE ELASTIC BODY HAVING MULTISTAGE ELONGATION CHARACTERISTICS AND METHOD OF MANUFACTURING THE SAME |
摘要 |
There is provided a composite elastic material comprising a non-woven fabric having an elongation along at least one direction and a break-down elasticity along said direction of 100% or more and a sheet-like elastic member having an elastic recovery of 60% or more and a break-down elasticity of 200% or more, with the elastic member and the non-woven fabric being secured together at a plurality of securements discontinuous in the stretchable direction of the non-woven fabric, and the method of producing the same. The composite elastic material provides multiple-stage elongation characteristic having a first stress lowering point caused by changes of structure of said non-woven fabric while being stretched along said direction, and a second stress lowering point occurring at an elongation larger than that said first stress lowering point lies, caused by break-down of said sheet-like elastic member. Therefore, the elastic material shows clearly a break-down point when stretched, and increases flexibility on designing various products. <IMAGE> |
