Differentially-stretched elastic laminate

摘要

An elastic material that lowers extension tension over a given range without a significant impact on the retractive tension or stress relaxation. The elastic laminate includes a first set of elastic members attached to one or more substrates while the elastic members are stretched, and a second set of elastic members or an elastic film attached to the one or more substrates while the elastic members or film are stretched to a different extent than the first set of elastic members. Both the substrate(s) and one of the sets of elastic members or film are gathered when the other set of elastic members or film is relaxed. Also included is a method of making the differentially-stretched elastic laminate.
