摘要:
A stretch laminate having enhanced features is disclosed. The laminate may include a first layer of nonwoven, a second layer of an elastomeric material, a third layer of a polyethylene and/or ductile polymeric film, and optionally, a fourth layer which may also be a nonwoven. The third layer may be bonded to the second layer in a pattern that includes bonded and unbonded areas. Following lamination the laminate may be activated to impart stretchability in a stretch direction. Activation causes plastic deformation/elongation of the third layer along the stretch direction, and upon elastic contraction of the second layer the deformed/elongated third layer gathers in the unbonded areas, creating desirable visual and tactile effects. The laminate has other advantages and may be provided with other features for enhancement of visual and/or tactile effects. The laminate may be used to form components of absorbent articles such as disposable diapers and training pants.
