Abstract

A nonwoven fabric for manufacturing repeatedly re-usable clean-room protective clothing, made of super microfilaments having a titer of less the 0.2 dtex that are produced by water jet splitting multicomponent multisegment filaments having a titer of less than 2 dtex, the primary filaments being spun from the melt, aerodynamically stretched, laid to form a nonwoven fabric, and subjected to water-jet prebonding prior to splitting.
