Abstract
A 3-dimensional fiber is disclosed that is constructed from first and second components. The first component is capable of being stretched and has a recovery percentage R1. The second component is also capable of being stretched and has a recovery percentage R2, wherein R1 is higher than R2. The first and second components are combined to form a linear fiber having an initial length that can be stretched at least 50%. The stretched fiber has the ability to retract to a length of from about 5% to about 90% of the stretched length to form a 3-dimensional fiber that exhibits elongation properties of at least 250% in at least one direction from the retracted length before the fiber becomes linear. A web formed from a plurality of 3-dimensional fibers is also disclosed.
