Abstract
A multicomponent fiber comprising one component comprising non-starch thermoplastic polymer and one component comprising a thermoplastic starch. The thermoplastic polymer component can surround the thermoplastic starch component. The thermoplastic starch can contain destructured starch and plasticizer. The multicomponent fiber has a greater elongation than a monocomponent thermoplastic fiber produced with the same thermoplastic polymer component materials and under the same processing conditions. Also provided are nonwoven webs and disposable articles comprising the multicomponent fibers.
