Modulus nonwoven webs based on multi-layer blown microfibers

摘要

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 MX1+MX2 where M1 and M2 represent the modulus values of webs formed from the two materials and X1 and X2 represent the respective volume portions of the materials in the web fibers.
