ABSTRACT:
A high modulus nonwoven web is produced using a high modulus material and a self-bonding material formed as multi-layer melt-blown microfibers where the web modulus is greater the MX.sub.1 +MX.sub.2 where M.sub.1 and M.sub.2 represent the modulus values of webs formed from the two materials and X.sub.1 and X.sub.2 represent the respective volume portions of the materials in the web fibers.
