| 摘要 |
The present invention is directed to elastic webs, such as elastic films and elastomeric fibrous meltblown or spunbond webs which may include elastomeric fibers and/or elastomeric continuous filaments. The elastic webs include an elastomeric block copolymer and an amorphous polyolefin plastomer wax. The elastic webs may include a tackifier, but desirably they do not. The elastic webs of the present invention may display hysteresis values and/or immediate set values upon elongation and retraction less than the hysteresis values and immediate set values of previously known elastic webs of similar basis weight. The elastic webs may display tension values upon elongation less than tension values displayed by previously known elastic webs of similar basis weight. The present invention is also directed to elastic laminate structures comprising at least one layer of an elastic web adhesively bonded to one or more other webs, such as, for instance a woven or nonwoven web. |
