ABSTRACT:
Degradable multilayer melt blown microfibers are provided. The fibers comprise (a) at least one layer of polyolefin resin and at least one layer of polycaprolactone resin, at least one of the polyolefin or polycaprolactone resins containing a transition metal salt; or (b) at least one layer of polyolefin resin containing a transition metal salt and at least one layer of a degradable resin or transition metal salt-free polyolefin resin. Also provided is a degradable web comprising the multilayer melt blown microfibers.
