Abstract
There is provided a nonwoven fabric laminate having cross-directional stretch properties. The laminate is comprised of at least three layers. The outer layers are spunbond nonwoven fiber webs which are made of crimped or crimpable fibers. The inner layer is an elastomeric polymer layer which may itself be composed of one or more thinner layers. The layers are preferably produced by sequentially depositing them onto a moving forming wire and bonding them together by a method excluding hydroentanglement to form the laminate.
Claims19
A laminate having cross-directional stretch comprising:
- a first layer of a crimpable spunbond polymer web made from fibers selected from the group consisting of biconstituent and bicomponent fibers;
- a second layer of an elastomeric polymer;
- a third layer of a crimpable spunbond polymer web made from fibers selected from the group consisting of biconstituent and bicomponent fibers;
- wherein said layers are bonded together by a method excluding hydroentanglement to form a laminate with an open bond pattern having between about 5 and 15 percent bond area, said layers are maintained in an unstretched condition throughout their production and bonding into said laminate, and wherein said laminate stretches in the cross direction.
