WEB MATERIALS HAVING ELASTIC-LIKE AND EXPANSIVE ZONES |
摘要 |
A web material exhibiting both an elastic-like and an expansive behavior in response to an applied elongation. The web material includes an elastic-like zone and an expansive zone disposed adjacent to the elastic-like zone. The expansive zone allows the elastic-like zone to extend without generating excessive tensional forces. The elastic-like zone includes a strainable network having a first region and a second region. The second region has a surface-pathlength greater than the surface-pathlength of the first region. The expansive zone has a surface-pathlength greater than the first region and different than that of the second region. |
